The reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms. In order to follow the conservation of matter, the products of the chemical equation will have

Answers

Answer:

The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).

Explanation:

According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, matter can be neither created nor destroyed. It can only be transformed.

Therefore, in a chemical reaction the atoms are conserved. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and the amount and type of atoms of the products will be the same as the reactants.

In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.

A 2.00 L pocket of air at sea level has a pressure of 99.9 atm. What is the
pressure if the pocket of air rises and expands to 8.0 L? *
0.04 atm
O
400 atm
25 atm
52 atm​

Answers

Answer:

The answer is 25 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{2 \times 99.9}{8} = \frac{199.8}{8} \\ = 24.975[/tex]

We have the final answer as

25 atm

Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie

a cube has a length of 1.02 cm and a mass of .001012 kg what is its density ​

Answers

Answer:

d = 9.5× 10⁻⁴ Kg/cm³

Explanation:

Given data:

Length of cube = 1.02 cm

Mass of cube = 0.001012 Kg

Density of cube = ?

Solution:

The length , height and width of cube is always same. Thus the volume of cube is,

Volume = length × height× width

Volume = 1.02 cm × 1.02 cm × 1.02 cm

Volume = 1.06 cm³

Density of cube:

d = 0.001012 Kg /1.06 cm³

d = 9.5× 10⁻⁴ Kg/cm³

If I place a balloon in my fridge that initially has a pressure of 1.02 atm and a
temperature of 11.2 °C, what will be the pressure (in atm) of the balloon when it is
fully cooled to 4.00°C by my refrigerator?

Answers

Answer:

P₂ = 0.99 atm

Explanation:

Given data:

Initial pressure = 1.02 atm

Initial temperature = 11.2°C

Final pressure = ?

Final temperature = 4.00°C

Solution:

Initial temperature = 11.2°C (11.2+273 = 284.2 K)

Final temperature = 4.00°C (4.00+273 = 277 K)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.02 atm / 284.2 K = P₂/277 K

P₂ = 1.02 atm × 277 K / 284.2 K

P₂ = 282.54 atm. K /293 K

P₂ = 0.99 atm

Answers

if I am correct I think its I'm am not 100 percent sure but I think this should be the answer

The gravitational force of attraction between them is 3.56 * 10⁻⁴ N

Using the formula of gravitational attraction

F = G*M1M2/d²

where G = 6.67 * 10⁻¹¹ Nm²Kg⁻²

M1 = 8000Kg

M2 = 1500 Kg

F =  6.67 * 10⁻¹¹ * 8000 * 1500 / (1.5)²

F = 3.56 * 10⁻⁴ N

Explanation:

a sample of carbon dioxide gas occupies a volume of 20 L at standard temperature and pressure (STP). what will be the volume of a sample of argon gas that has the same number of moles and but tripled the absolute temperature?​

Answers

Volume of Argon = 59.972 L

Further explanation

In general, the gas equation can be written  

[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

At STP(0 C, 1 atm), 1 mol gas= 22.4 L

so for 20 L

[tex]\tt \dfrac{20}{22.4}=0.893[/tex]

For Argon

P = 1 atm

T = 273 K x 3 =819 K (tripled)

n = 0.893 (the same number of moles)

R = 0.082 L/atm.mol K

[tex]\tt V=\dfrac{nRT}{P}=\dfrac{0.893\times 0.082\times 819}{1}=59.972~L[/tex]

If a compound begins with a metal, it most likely is a _______ compound

metallic

molecular

covalent

ionic

Answers

Answer:

A

Explanation:

If a compound begins with metal, it is most likely to be a metallic compound. Thus, option A is correct.

The metallic compound has been formed when the metal has been bonded with a metal or more than 1 metal by the ionic or covalent interaction.

The ionic interactions result in between the metal and non-metal or between two metals, and the covalent interactions have been found in the nonmetals.

The molecular compound has been the one that has been formed a molecule. All the compounds are molecular compounds.

Thus, if it starts with metal, it has been most likely to form a metallic compound. Thus, option A is correct.
