Using the gas laws, the volume of nitrogen produced is 6.6 L.

<h3>What is the product of a reaction?</h3>

We know that the product of a reaction is obtained from the balanced reaction equation. The reactants combine together to yield the products hence we have; N2 + 3H2 ----> 2NH3

We know that 1 mole of hydrogen occupies 22.4 L

x moles of hydrogen occupies 25500 L

x = 1 mole * 25500 L/ 22.4 L

x = 1138.4 moles

If 3 mole of hydrogen reacts with 1 mole of nitrogen

1138.4 moles  reacts with 1138.4 moles * 1 mole/ 3 moles = 379.5 moles

Mass of nitrogen = 379.5 moles * 28 g/mol = 10626 g

Now 3 moles of hydrogen produces 44.8 L of NH3

1138.4 moles  produces 1138.4 moles * 44.8 L/ 3 moles = 17000 L

Now;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2 = 1 * 17000 * 848/5.5 * 273

V2 =9601 L

2) 2NH4NNO3(s) ---> 4H2O(g) + 2N2(g) + O2(g)

Number of moles = 12g/ 80 g/mol = 0.15 moles

Now;

2 moles of NH4NNO3 produced 2 moles of nitrogen hence 0.15 moles of N2 was produced.

1 mole of N2 occupies 22.4 L

0.15 moles of N2 occupies 0.15 moles  *  22.4 L/1 mole = 3.36 L

P1 = 760 torr

V1 = 3.36 L

T1 = 273 K

P2 = 745 torr

T2 = 527 degrees or 800 K

V2 = ?

V2 =  P1V1T2/P2T1

V2 =  760 *  3.36 * 527/745 * 273

V2 = 6.6 L

Name the following in aqueous solution: HClO2
AfilCa [17]

The first letter is an H (hydrogen) so the compound is an acid. Since the rest of the compound is a polyatomic ion, we do not use the prefix hydro-.

The name of the polyatomic ion ClO2- is chlorite (see a polyatomic ion chart to confirm).

Drop the ending -ite and replace with -ous acid.

So the name is chlorous acid (aq).

What is the volume of 0.80 grams of O2 gas at STP?
frez [133]

Answer:

The volume of 0.80 grams of O2 is 0.56 L

Explanation:

Step 1 : Data given

Mass of O2 = 0.80 grams

Molar mass of O2 = 32 g/mol

STP = 1 mol, 1atm, 22.4 L

Step 2: Calculate moles of oxygen

Moles of O2 = Mass of O2 / molar mass of O2

Moles O2 = 0.80 grams / 32 g/mol

Moles O2 = 0.025 moles

Step 3: Calculate volume of O2

1 mol = 22.4 L of gas

0.025 moles = 0.025*22.4L = 0.56 L

The volume of 0.80 grams of O2 is 0.56 L

What is neurilemma...explain citing its difference with Myelin Sheath
Dmitry [639]

Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. ... In the central nervous system, axons are myelinated by oligodendrocytes, thus lack neurilemma.

3) Calculate how many formula units are in 7.11 moles of CaCl2.<br>​
Natalka [10]

Answer:

42.82 × 10²³ formula units

Explanation:

Given data:

Number of moles of CaCl₂ = 7.11 mol

Number of formula units = ?

Solution:

We will solve this problem by using Avogadro number.

1 mole of substance contain 6.022× 10²³ formula units.

7.11 mol × 6.022× 10²³ formula units / 1mol

42.82 × 10²³ formula units
