The new volume of a sample of gas initially occupying a 500 mL container at a pressure of 1.4 atm and a temperature of 25 °C is 281.01mL.

The volume of a gas can be calculated using the following formula:

P1V1//T1 = P2V2/T2

Where;

1.4 × 500/298 = 2.7 × V2/323

2.348 × 323 = 2.7V2

758.72 = 2.7V2

V2 = 281.009mL

Therefore, the new volume of a sample of gas initially occupying a 500 mL container at a pressure of 1.4 atm and a temperature of 25 °C is 281.01mL.

The relative atomic mass of x is 101 u.

Molar mass is calculated by adding the atomic mass of all the elements in a compound.

Molar mass of x(HCO₃) =162 g/mol

Atomic mass of H = 1 g/mol

Atomic mass of C =12 g/mol

Atomic mass of O = 16 g/mol

Therefore, molar mass of x(HCO₃) will be

Answer:

Chemical bonds are how atoms, and even molecules join together.

Explanation:

There are two main types of primary chemical bonds. While secondary links relate to molecules, primary ties are atom to atom. This answer explains basic primary bonds only.

One must comprehend what a valence shell is before I proceed. The outer electron orbital of an atom is known as the valence shell. Most of the time (except from hydrogen), atoms desire to have 8 electrons in their valence shell, thus they form bonds with other atoms to accomplish this.

All bonds result in a new chemically different molecule. Now, the two types are:

Answer:

D. The amount of nitrogen dioxide and sulfur dioxide would increase.

Explanation:

Because the reaction is exothermic, heat is a product. According to Le Chaetelier's Principle, a system in equilibrium will adjust itself so as to relieve any stress placed upon it. If the temperature of the system increases, there are more products, and therefore the system is no longer at equilibrium. Thus, it will shift to favor the reactant side of the equation, where sulfur dioxide and nitrogen dioxide are located. This makes the answer D.

Edit: Brainly thinks that the correct spelling of 'Le Chaetelier' is a bad word so that's why it is spelled wrong lol.

Answer:

X = 350 kJ/mol

Explanation:

According to the question:

Energy needed when breaking bonds  +  1640 kJ/mol   =   Energy released when forming bonds

∴ 2 (C - C) + 8 (C - H) + 5 (O = O) + 1640 = 6(C = O) + 8(O - H)

⇒ 2 (X) + 8 (410) + 5 (500) + 1640 = 6 (740) + 8 (460)

⇒ 2X  +  7420  =  8120

⇒ 2X = 700

⇒ X = 350 kJ/mol

Answer:

B. Optical

Explanation:

First, let's go through what isomerism is. Isomerism is the relation of two or more compounds, radicals, or ions that are composed of the same kinds and numbers of atoms but differ from each other in structural arrangement (structural isomerism), as CH3OCH3 and CH3CH2OH, or in the arrangement of their atoms in space and therefore in one or more properties.  There are 5 types of structural isomerism. They are chain isomerism, position isomerism, functional group isomerism, metamerism, and tautomerism. This would mean that these types of structural isomerism that are in the options would be eliminated as the question ask which of the "following" is not a type of structural isomerism. This would leave the only option available which is Option B. Optical Isomerism. So instead of being a structural isomerism, it is a type of stereoisomerism. Stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in space is different in each isomer.

Therefore, the answer is Option B. Optical.

Answer:

=> 1.0 M

Explanation:

The question is asking us to find the molarity of the acid (HCl).

We have been provided with;

We know that molarity (M) of a solution is contained in 1 L or 1000 mL or 1000 cm³.

This means that;

0.40 M is contained in 1000 mL.

X mol is contained in 25.0 mL

[tex] = \frac{25 \: \times \: 0.40}{1000} \\ = 0.01 \: moles[/tex]

These 0.01 moles is contained in 10 mL of HCl.

To find the molarity of the acid;

0.01 moles is contained in 10 mL

x mol is contained in 1000 mL

[tex]x \: mol \: = \frac{0.01 \times 1000}{10} \\ = 1.0 \: mol[/tex]

= 1.0 M

Therefore the molarity of the acid (HCl) is 1.0 M

Answer:

independent: amount of baking powder

dependent: the banana bread that it produces

constants: the amount of other ingredients/the other ingredients, the type of baking powder, rest of the baking process (heat, temperature, timing of steps), and who's tasting the bread.

Explanation:

The independent variable is the thing that we are directly changing.

We usually change this to test out differences between different amounts of this variable;

This variable is the "x" variable in a function or graph, if it helps you to think of it as that.

The dependent variable is the thing that changes because of the independent variable

Once again, if you think of a graph or function, this would be the "y" variable--it changes in relation to x

The constants are the things that stay the same no matter what the changing variables are

This element is key to an experiment--an experiment would be almost pointless without it. We need to see what is actually changing as a result of the independent and intentional changes.

Here's an example:

Let's say I want to test out how much condensation forms on a bottle based on the temperature of the liquid inside.

I will be changing the temperature of the liquid inside, meaning that this is the independent variable

I will be expecting/looking for a change in the condensation because of my change in the independent variable, meaning that this is the dependent variable

In my experiment, there are some things I need to make sure don't change, so that I can see the effect of my change in the temperature directly--perhaps I need to keep the same bottle shape and size, the same amount of liquid, the same location, the same type of liquid, the same amount of time I let it sit for, etc.  meaning that these are my constants.

So, with all of this in mind, let's take a look at our experiment given.

Here, I will be changing the amount of baking powder that I use, whilst observing the change in the banana bread that it directly produces.

There are a few things I must keep constant: the amount of the other ingredients, the rest of the baking process (heat/temperature, mixing time, etc.), and the type of baking powder I use

There is another consideration that I probably want to keep consistent: who is deciding the taste of the bread. If the person switches, then I might get a different opinion for the same recipe.

hope this helps! have a lovely day :)

Option 2 involves conducting an experiment to find the ideal amount of baking powder to add to a batch of banana bread.

The amount of baking powder served as the independent variable. The goal of this experiment is to determine the ideal amount of baking powder to use in each batch of banana bread.

Dependent Variable: The standard of banana bread served as the dependent variable. It is called the outcome you are measuring or observing in response to a change in the independent variable. In this instance it could be the taste, texture or texture of banana bread.

Constant: Some variables must remain constant throughout the experiment to ensure that only the independent variable has an effect on the dependent variable. Following are some possible constants in this experiment:

By holding these variables constant, you can isolate the effect of different amounts of baking powder on the quality of the banana bread and determine the exact amount needed for best results.

110ml of the 40% alcohol mixture and pure water will  need to obtain the desired solution

Given that 0.30 * 440 = 132 mL of pure alcohol needed

132 mL = 0.40 * x mL of 0.4

x = 330 mL of 70%

440 - 330 = 110 mL of H2O

Water content differs

If you have 440 mL of a 30% alcohol mixture, then (440mL)*(0.30) = 132mL of that solution is alcohol.

Similarly, if you have x mL of a 40% alcohol mixture, then (x mL)(0.40) = 0.40x mL of that solution is alcohol.

When you combine these two liquids, you will have (440 + x) mL of liquid and you want it to be 40% alcohol.

Hence  110ml of the 40% alcohol mixture and pure water will  need to obtain the desired solution

If an electron in an atom gains energy to go from a lower energy level to a higher energy level, it is called Excited energy state.

Ground state energy: The lowest energy state for an electron is called its ground state, which is the energy level it typically resides in. Each electron has a limit on how much energy it can have while still remaining a part of its atom. It is the most stable state of electron.

Excited state energy: An electron is in an excited state when it momentarily possesses an energy state higher than its ground state. If an electron receives additional energy, such as when it absorbs a photon, or packet, of light, or collides with an adjacent atom or particle, it can become excited. As these excited state energy level are unstable. So while coming back to ground state electrons emit radiations suitable wavelength.

Explanation:

To determine the formula to use in solving such a problem, you have to consider what you have been given.

We have;

mass (m)     = 25 Kg

Volume (v) = 18.3 mL.

From our question, we are to determine the density (rho) of the rock.

The formula:

[tex]p = \frac{m}{v}[/tex]

First let's convert 25 Kg to g;

1 Kg    = 1000 g

25 Kg = ?

[tex]= \frac{25 × 1000}{1}[/tex]

= 25000 g

Substitute the values into the formula:

[tex]p = \frac{25000 g}{18.3 ml}[/tex]

= 1366.120 g/mL.

Therefore, the density (rho) of the rock is  1366.120 g/mL.

The ionized uranium (238 [tex]U^{5+}[/tex]) has 92 protons, 146 neutrons and 87 electrons.

The U²³⁸ is a stable isotope of Uranium. It cannot sustain a chain reaction.

The atomic number for uranium is 92 and its atomic mass is 238.

The atomic number for U²³⁸ is 92.

So, the number of protons or electrons = 92

Then, the number of neutrons = atomic mass - number of protons

⇒ 238 - 92 = 146

The Uranium is ionized and becomes ²³⁸U⁵⁺.

So,

The number of protons = 92

The number of electrons = 92 - 5 = 87 (Since uranium is ionized by 5+ electrons i.e., removing 5 electrons)

The number of neutrons = atomic mass - number of protons

= 238 - 92 = 146

Thus, when uranium ionizes and becomes ²³⁸U⁵⁺, there are 92 protons, 146 neutrons, and 87 electrons.

In this pair, NH3 is a weak base, which gets its basic character due to the presence of lone pair of nitrogen and its ability to donate it.

The limiting reagent will be Al

They are reagents that limit the quantity of products that are formed in reactions.

From the equation of the reaction:

The mole ratio of Al to O2 is 4:3.

With 2 moles of Al and 2 moles of O2, Al becomes limiting while O2 is in excess.

With 2 moles of O2, the amount of Al required should be:
