Calculate the volume in mL of 53.2 g of .251M solution of HCl.

Answers

Answer 1

Answer:

5.813 mL

Explanation:

You need to use the formula : vol = mass / molar mass x molarity

the molar mass of HCl is 36.46 and the problem gives you the rest of the equation

0.251M x 36.46 = 9.151

53.2g / 9.151 = 5.813 mL

Calculate the molar mass of a sample if a single molecule weighs 2.55 x 10^-23 g.

Answers

molar mass= energy x mass= 10 x 2.55 x 10^-23

Avogadro's number (NA) or Avogadro's constant (6.0221 x 10^23). The term "mole" is defined as that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram.

What is Avogadro's number?

The number of molecules in one mole is 6.022 * 10^ 23 numbers. The molecular mass of the molecule is 2.55 x 10^-23

Molar mass can be defined as 'mass per mole.' In other words, molar mass is the sum of the mass of all the atoms found in one mole's worth of a substance. It is expressed in units of grams per mole.

Molar mass is depicted for elements or molecules. In the case of single elements or individual atoms, the molar mass would just be the element's mass expressed in atomic mass units.

Molar mass =  2.55 x 10^-23/ 6.022 * 10^ 23

                   = 0.423

Therefore, Avogadro's number (NA) or Avogadro's constant (6.0221 x 10^23). The term "mole" is defined as that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram.

A larger balloon has 2.5 l of nitrogen gas at 298 k . If the temperature is increased to 333 k , what will be the new volume of balloon filled with nitrogen

Answers

Answer: The new volume of baloon filled with nitrogen is 2.8 L

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where,

[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.

[tex]V_2\text{ and }T_2[/tex] are the final volume and temperature of the gas.

We are given:

[tex]V_1=2.5L\\T_1=298K\\V_2=?\\T_2=333K[/tex]

Putting values in above equation, we get:

[tex]\frac{2.5}{298}=\frac{V_2}{333}\\\\V_2=2.8L[/tex]

Thus the new volume of baloon filled with nitrogen is 2.8 L

Calculate the equilibrium constant of the reaction below if the pressures are 1.0atm, 2.0 atm, and 1.0 atm respectively. PCl3 + Cl2 <--> PCl5

Answers

Answer:

K = 0.5

Explanation:

Based on the reaction:

PCl₃ + Cl₂ ⇄ PCl₅

The equilibrium constant, K, is defined as:

K = P PCl₅ / P PCl₃ * P Cl₂

Where P represent the pressure at the equilibrium for each one of the gases involved in the equilibrium.

As:

P PCl₅ = 1.0atm

P PCl₃ = 1.0atm

P Cl₂ = 2.0atm

K = 1.0atm / 1.0atm * 2.0atm

K = 0.5

a- Balance the equation
b- Find the limiting reactant when 2.5 g H,PO, react with 4 g of KOH
C- What is the excess reactant?
d- How much of the excess reactant remained after reaction proceeded?

Answers

Explanation:

a.H2PO4 + 2KOH = K2PO4 + 2H2O

b. H2PO4 _ 2KOH

1(2) + 31 + 16(4) _ 2(23) + 2(16) + 2(1)

2 + 31 + 64 _ 46 + 32 + 2

97 _ 80

no of moles of H2PO4 = 2.5 ÷ 97

= 0.026mol

no of moles of 2KOH = 4 ÷ 80

= 0.05mol

2KOH is the limiting reactant

c. H2PO4 is the excess reactant

d. 1 mole H2PO4 weighs 2.5g

0.026mol H2PO4 weighs g

(0.026 × 2.5)

H2PO4 weighed 0.065g after reaction

If a sulfur atom gained 3 protons what atom would be formed?

Answers

Answer:

The stable ion the sulfur would form is the sulfide ion,

Explanation:

When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.

Sulfur is an elemental atom that has an atomic number of 16 and an atomic mass of 32.065 amu. If the sulfur atom gains three protons then potassium will be formed.

What is a proton?

A proton has been a sub-atomic particle that has been known to carry a positive charge and are tend to remain inside the nucleus with the neutrons bonded together by the nuclear force.

The proton of the atom is the characteristic property of the element in the periodic table. They are the sole sub-atomic particle that gives the atomic number of the elemental atom.

The sulfur atom has the atomic number 16 which means it has 16 protons, so if three protons are added to it then the number f protons become 19 which is an atomic number of the potassium (K) element.

Therefore, a potassium element is formed.

3 moles de hierro con 4 moles de agua producen 1 mol de óxido de hierro y 4 moles de hidrógeno (gas)

Cuando la reacción se está produciendo con un recipiente abierto, todo el gas de hidrógeno está escapando a la atmósfera y no habrá forma de que reaccione con el óxido de hierro.

Pero, si el recipiente está cerrado, el hidrógeno no podrá escapar y podrá reaccionar con el óxido de hierro, así:

Fe₃O₄ + 4H₂(g) → 3Fe + 4H₂O
