Which factor can increase solubility?

1 answer:

7 0

Solubility is the maximum amount of a substance that will dissolve in a givenamount of solvent at a specifictemperature. There are two direct factors that affect solubility:temperature and pressure.Temperature affects the solubility of both solids and gases, but pressureonly affects the solubility of gases.Jul 12, 2012 More info at https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.ck12.org/user:krogers/section/Factors-Affecting-Solubility/&ved=0ahUKEwjrhrbkgaLSAhWBTSYKHf2_CwgQFggdMAE&usg=AFQjCNEpdOlW5dWQ1GlXoJu_ufz-FhKJAQ&sig2=tPbfrbEnhCcyUiSCkWaH7w

A sample of glucose contains 1.250x10^21 carbon atoms, how many atoms of hydrogen does it contain?

dybincka [34]

Answer:

Hydrogen = 2.5 * 10^21

Explanation:

Chemical Formula Glucose: C₆H₁₂O₆

One of the ways you could do this is to notice that for every carbon atom there are two Hydrogen atoms. You can state this more formally by using the formula to set up a ratio: 12/6 = hydrogen to Carbon

So if there are 1.250 * 10^21 Carbon atoms in the Glucose sample, then there will be twice as many hydrogen atoms.

H = 2 * 1.25 * 10^21 = 2.5 * 10^21 atoms

You could do this more formally by setting up a proportion.

6 Carbon / 12 Hydrogen = 1.25*10^21 / x Cross Multiply

6*x = 12 * 1.25*10^21 Combine the right

6x = 1.5 * 10^22 Divide by 6

x = 2.5 * 10^21

How many moles of KCIO3 most decompose to form 13.0 moles of potassium chloride?

Elden [556K]

Answer:

13 moles of KClO₃ will decompose to gives 13 moles of KCl.

Explanation:

Given data:

Moles of potassium chloride = 13.0 mol

Moles of KClO₃ = ?

Solution:

Chemical equation:

2KClO₃ → 2KCl + 3O₂

Now we will compare the moles of KCl with KClO₃.

KCl : KClO₃

2 : 2

13 : 13

So 13 moles of KClO₃ will decompose to gives 13 moles of KCl.

solution is 2.41 molal toluene (C 7H 8, 92 g/mol) in benzene (C 6H 6, 78 g/mol); i.e. consider toluene the solute, benzene the s

inn [45]

Answer : The molarity of solution is, 1.73 mole/L

Explanation :

The relation between the molarity, molality and the density of the solution is,

where,

$d=M[\frac{1}{m}+\frac{M_b}{1000}]$

d = density of solution = $0.876g/cm^3=0.876g/mL$

m = molality of solution = 2.41 mol/kg

M = molarity of solution = ?

$M_b$ = molar mass of solute (toluene) = 92 g/mole

Now put all the given values in the above formula, we get the molality of the solution.

$0.876g/ml=M\times [\frac{1}{2.41mol/kg}+\frac{92g/mole}{1000}]$

$M=1.73mol/L$

Therefore, the molarity of solution is, 1.73 mole/L

Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of

Vedmedyk [2.9K]

Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of two atoms of nitrogen.

The correct option is C.

Explanation:

Nitrogen gas has the chemical formula $N_{2}$ , which means that two atoms of nitrogen element combined to form nitrogen gas.

The combination of two atoms of element nitrogen produce dinitrogen atom.

Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.

2 atoms of nitrogen element

N + N = $N_{2}$

the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.
