Answer: D) dinitrogen trioxide

Explanation:

$N_2O_3$ is a covalent compound because sharing of electrons takes place between nitrogen and oxygen. Both the elements are non-metals and hence, will form covalent bond.

The nomenclature of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.

3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.

Thus the name of $N_2O_3$ is dinitrogen trioxide.

If 1.00L of muriatic acid w/ a pH of 2.5 is poured to 8.00L water, what is the new molar concentration of the muriatic solution?

Daniel [21]

Answer:

The answer to your question is: C2 = 0.0004 M

Explanation:

Data

pH = 2.5; V = 1.0 L

V2 = 8.0 L C2 = ?

Formula

C1V1 = C2V2

C2 = C1V1 / V2

pH = -log[H⁺]

Process

[H⁺] = antilog -pH

[H⁺] = antilog (-2.5)

[H⁺] = 0.003 M = C1

Finally

(0.003)(1 l) = C2(8)

C2 = 0.003 / 8

C2 = 0.0004 M

What is the molarity of a solution that contains 0.23 mol HCL in a 9.75 L solution

Paul [167]

Answer:

23.59

Explanation:

molarity=moles x1000÷volume

$0.23 \times 1000 \div 9.75 = 23.5897 \\ = 23.59m$

Why is it easier to remove an electron from a sodium atom than a magnesium atom

gulaghasi [49]

It doesn't take much energy to remove one electron from a sodium atom to form an Na+ ion with a filled-shell electron configuration. The first ionization energy of magnesium is larger than sodium because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital.

Calculate the molality of a solution containing 15.01 g of glycerol (c 3h 8o 3) in 42.3 g of ethanol (c 2h 5oh).

kkurt [141]

The molality of the glycerol solution is 3.854mol/kg

The number of moles of solute present in a solution equal to 1 kg or 1000 g of solvent is referred to as its molality.

Given:

Mass, m1 of glycerol = 15.01g

Mass, m2 of ethanol = 42.3g

Molar mass, mm1 of glycerol = 92.095g/mol

Molar mass, mm2 of ethanol = 46.069g/mol

To find:

Molality, m = ?

Formula:

Molality, m = moles of solute / kg of solvent

Calculations:

No. of moles of glycerol = 15.01 x (1/92.095)

n = 0.163 mols

Molality, m = 0.163 / 0.0423g

Molality, m = 3.854mol/kg

Result:

3.854mol/kg is the molality of the glycerol solution.

What is the mass, in grams, of 0.125 L of CO2 at STP? Question 4 options: 2.80 g 181 g 0.246 g 4.11 g

Zolol [24]

1) Use the fact that 1 mol of gas at STP occupies 22.4 liter

=> 1 mol / 22.4 l = x / 0.125 l => x = 0.125 l * 1 mol / 22.4 l = 0.00558 mol

2) Now use the molar mass of the gas

molar mass of CO2 ≈ 44 g / mol

Formula: molar mass = mass in grams / number of moles =>

mass in grams = molar mass * number of moles = 44 g/mol * 0.00558 moles

mass = 0.246 g

Answer: 0.246 g
