Answer:

The answer to your question is: water, polar solvent.

Explanation:

Data

sample of CaCl2

Solid copper this option is incorrect because in order to dissolve something the solvent must be liquid and this is a solid solvent.

water, I think this option is right, because CaCl2 is ionic and water is a polar solvent, CaCl2 will dissolve in water.

a polar solvent, CaCl2 will dissolve is a polar solvent like water, this option is correct.

hexane, CaCl2 will not dissolve in hexane because hexane is a non polar solvent and CaCl2 is ionic. This option is wrong

a nonpolar solvent This option is not right, CaCl2 will only dissolve in polar solvents.

liquid mercury, This option is wrong, mercury is not a solvent.

A bike tire reads a pressure of 13.2 psi. What is the
BaLLatris [955]

Answer:

0.89821 atm

Explanation:

Psi and atm are units of pressure.

Psi stands for pound force per square inch.

While atm stands for atmosphere.

In order to convert the psi to atm we would divide the given value 14.696.

Given value = 13.2 psi

In atm:

13.2 / 14.696 = 0.89821 atm

Explain the composition of dna nucleotides and the structure of the dna molecule need help
Kaylis [27]

A nucleotide is composed of a phosphate group, sugar, and nitrogen base. DNA is made of 2 strands of nucleotides linked together by covalent bonds between the phosphate and sugar of each nucleotide. The strands of nucleotides are linked together by hydrogen bonds creating DNA. Hope this helps and sorry if I made a mistake.

Solid ammonium chloride, NH4Cl, is formed by the reaction of gaseous ammonia, NH3, and hydrogen chloride, HCl. NH3(g)+HCl(g)⟶NH4
Mashutka [201]

9.41 atm is the pressure in atmospheres of the gas remaining in the flask

<h3>What is the pressure in atmospheres?</h3>

The equation NH3(g) + HCl(g) ==> NH4Cl(s) is balanced.

Divide the moles of each reactant by its coefficient in the balanced equation, and the limiting reagent is identified as the one whose value is less. With the issue we now have...

6.44 g NH3 times 1 mol NH3/17 g equals 0.3688 moles of NH3 ( 1 = 0.3688)

HCl: 6.44 g of HCl times one mole of HCl every 36.5 g equals 0.1764 moles ( 1 = 0.1764). CONTROLLING REAGENT

NH4Cl will this reaction produce in grams

0.1764 moles of HCl multiplied by one mole of NH4Cl per mole of HCl results in 9.44 g of NH4Cl (3 sig. figs.)

the gas pressure, measured in atmospheres, that is still in the flask

NH3(g) plus HCl(g) results in NH4Cl (s)

0.3688......0.1764............0..........

Initial

-0.1764....-0.1764........+0.1764...Change

Equilibrium: 0.1924.......0...............+0.1924

There are 0.1924 moles of NH3 and no other gases in the flask. This is at a temperature of 25 °C (+273 = 298 °K) in a volume of 0.5 L. After that, we may determine the pressure by using the ideal gas law (P).

PV = nRT

P = nRT/V = 0.1924 mol, 0.0821 latm/mol, and 298 Kmol / 0.5 L

P = 9.41 atm

9.41 atm is the pressure in atmospheres of the gas remaining in the flask
