A gas is contained in a thick-walled
balloon. When the pressure
changes from 1.21 atm to 2.52 atm,
the volume changes from 3.75 L to
1.72 L and the temperature changes
from 293 K to____________ K.
Which variable is held constant?
A.P B.V C.n D.T
Thank you! :)

Answers

Answer:

C.) n

Explanation:

-----> P = pressure (atm)

-----> V = volume (L)

-----> T = temperature (K)

-----> n = number of moles

According to the problem, it seems like pressure (P), volume (V), and temperature (T) are all changing. The problem never brings up whether the number of moles (n) has changed. Therefore, the number of moles (n) must have been held constant.

________________________________________________________

If you need to know what the temperature changes to....

When the number of moles is held constant, you can find the change in the other variables using the Combined Gas Law equation:

P₁V₁ / T₁ = P₂V₂ / T₂

In this formula, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the final pressure, volume, and temperature. You can find the final temperature by plugging in the given values and simplifying.

P₁ = 1.21 atm                      P₂ = 2.52 atm

V₁ = 3.75 L                        V₂ = 1.72 L

T₁ = 293 K                         T₂ = ? K

P₁V₁ / T₁ = P₂V₂ / T₂                                       <----- Equation

(1.21 atm)(3.75 L) / (293 K) = (2.52 atm)(1.72 L) / T₂         <----- Insert values

0.015486 =  (2.52 atm)(1.72 L) / T₂              <----- Simplify left side

0.015486 = 4.3344 / T₂                               <----- Multiply 2.52 and 1.72

0.015486 x T₂ = 4.3344                               <----- Multiply both sides by T₂

T₂ = 279.885                                                <----- Divide both sides by 0.015486

T₂ = 280 K                                                   <----- Answer in correct sig figs

Answers

The rate constant is mathematically given as

K2=2.67sec^{-1}

What is the Arrhenius equation?

The rate constant for a particular reaction may be calculated with the use of the Arrhenius equation. This constant can be stated in terms of two distinct temperatures, T1 and T2, as follows:

[tex]ln(\frac{K2}{K1})= (\frac{Ea}{R})*(\frac{1}{T1}-\frac{1}{T2})[/tex]

Therefore

KT1= 0.0110^{-1}

T1= 21+273.15

T1= 294.15K

T2= 200  

T2=200+273.15

T2= 473.15K

Ea= 35.5 Kj/Mol

Hence, in  j/mol R Ea is

Ea=35.5*1000 j/mol R

[tex]ln(\frac{K2}{0.0110})= (\frac{35.5*1000}{8.314})*(\frac{1}{294.15}-\frac{1}{473.15}\\\\ln(\frac{K2}{0.0110})=5.492[/tex]

K2/0.0110 =e^(5.492)

K2/0.0110 =242.74

K2= 242.74*0.0110

K2=2.67sec^{-1}

How many grams of magnesium chloride must be added to 725 mL of water to create a solution with an anion concentration equal to 0.800 M

Answers

55.2218 grams of magnesium chloride must be added to 725 mL of water to create a solution with an anion concentration equal to 0.800 M.

How to calculate the no. of moles ?

To calculate the number of moles from molarity as

[tex]\frac{\text{x moles}\ MgCl_2}{0.725\ \text{L solution}} = \frac{0.8\ \text{moles}\ MgCl_2}{1.0\ \text{L solution}}[/tex]

x moles MgCl₂ = [tex]\frac{0.8\ \text{moles}\ MgCl_2}{1.0\ \text{L solution}} \times 0.725\ \text{L solution}[/tex]

                         = 0.58 moles MgCl₂

What is Molar Mass ?

Mass of one mole of substance is known as molar mass.

Molar mass of MgCl₂ = Atomic mass of Mg + 2 (Atomic mass of Cl)

                                   = 24.31 + 2 (35.5)

                                   = 95.21

Convert moles to grams

0.58 moles MgCl₂ × [tex]\frac{95.21\ g}{1\ \text{mole}\ MgCl_2}[/tex]

Guanine pairs with cytosine using ______ noncovalent hydrogen bonds, while adenine pairs with thymidine using ______ noncovalent hydrogen bonds. Multiple choice question. two; two

Answers

Guanine pairs with cytosine using three noncovalent hydrogen bonds, while adenine pairs with thymidine using two noncovalent hydrogen bonds.

Why does cytosine and guanine have 3 hydrogen bonds?

Cytosine and guanine are joined by three hydrogen bonds. The Watson and Crick bases differ from one another in strength as a result. Thymine and adenine bonded base pairs in DNA are weaker than guanine and cytosine bonded base pairs. Size and structure of the specific nucleotides cause Adenine and Thymine to always pair together while Cytosine and Guanine always pair together.

Adenine and thymine can make two hydrogen bonds, while cytosine and guanine can form three hydrogen bonds. Or, to put it more simply, A and G form bonds. Because each base can only link with one other base, the process is known as complementary base pairing.

What conclusion can you make about the atomic number and the number of neutrons for the first 20 elements of the Periodic Table?

Answers

Answer: It has more neutrons. Its mass number is larger than the atomic mass number for carbon.

Explanation:

We can see that all the isotopes of Carbon occupies the same slot in the periodic table and thus the same periodic number.

Atomic number of carbon = 6

Periodic Table gives us the information of Atomic number and mass number of atoms of an element.

Atomic number does not give any information about the number of neutrons of an atom. Atomic number of an element is the number of protons in the nucleus of each atom of that element.

Mass number is defined as the total number of protons and neutrons in an atom. Mass number of a typical carbon atom is equal to 12.

Isotopes are variants of a particular chemical element which differ in number of neutrons. Hence, the mass number of different isotopes of the same element varies and gives us information about the number of neutrons present in that atom at the same time.

The mass number of Carbon-14 is equal to 14.

Atomic number of C-14 = Protons in Carbon-14 = 6

Neutrons in Carbon-14 = Mass Number - Atomic Number

Neutrons in C-14 = 14-6

The atmospheric pressure on mars is around 7 millibar, where the gravitational constant
is 3.7 m/s² instead of Earth's 9.8 m/s². What height of water column would be stable on
Mars? Assume a density of water of 1.0g/mL.

Answers

The height of water column would be stable on Mars is 1.89 m

To answer the question, we need to know what the pressure on mars is

What is the pressure on mars?

The pressure on mars P = ρgh where

ρ = density of water = 1.0 g/mL = 1.0 × 10⁻³ kg/1 × 10⁻³ L = 1 kg/L = 1 kg/1 × 10⁻³ m³ = 1000 kg/m³, g = acceleration due to gravity on mars = 3.7 m/s² and h = height of water column.

Height of water column

Making h subject of the formula, we have

h = P/ρg

Since

P = 7 mbar = 7 × 10⁻³ bar = 7 × 10⁻³ × 10⁵ Pa = 700 Pa,ρ = 1000 kg/m³ and g = 3.7 m/s²

Substituting the values of the variables into the equation, we have

h = P/ρg

h = 700 Pa/(1000 kg/m³ × 3.7 m/s²)

h = 700 Pa/370 kg/m²s²

h = 1.89 m

So, the height of water column would be stable on Mars is 1.89 m

In a filtration experiment 25cm of a solution of a sodium hydroxide contain 8g per litre was required for complete neutralization of 0.245g of a diabasic acid. Calculate the relative molecular mass of the acid (Na= 23, O=16,H=1)

Answers

The relative molecular mass of an element is a proportion of the mass of the unified amu. The relative molecular mass of sodium hydroxide is 40.

What is molecular mass?

The molecular mass of a substance is an addition of the individual masses of the element that makes the compound.  

Moles of NaOH = 8 mole

Molarity = 0.2 M

Moles of sodium hydroxide in 25 cm³: 25 × 0.2 = 0.005 moles

The mole ratio between the two moles:

0.2 ÷ 0.005 = 40

Therefore, 40 is the relative molecular mass of the acid.
