Answer:

V = 82.31L

Explanation:

Number of moles (n) = 3.88 moles

Temperature (T) = 28.0°C = (28.0 + 237.15)k = 301.15K

P = 885torr = 1.164atm (convert pressure in torr to atm)

1 atm = 760torr

x atm = 885 torr

X = (885 * 1) / 760

P = 1.164atm.

Volume (V) = ?

R = 0.082J/mol.K

From ideal gas equation,

PV = nRT

P = pressure

V = volume of the gas

n = number of moles

R = idealgas constant

T = temperature

PV = nRT

V = nRT/ P

V = (3.88 * 0.082 * 301.15) / 1.164

V= 82.31L

The volume of the gas is 82.31L

Answer:

Its volume is 82.3 L

Explanation:

The state of a quantity of gaseous matter is formulated based on four different variables: pressure, volume, temperature and number of moles of gas. Then, the equation known as the ideal gas equation, explains the relationship between these four variables using the expression:

P*V=n*R*T

where P represents the gas pressure, V its volume, n the number of moles of gas, R the gas constant and T the gas temperature.

In this case:

  • P= 885 torr
  • V=?
  • n=3.88 mol
  • R= 62.36365 \frac{L*torr}{mol*K}
  • T=28°C= 301°K (Being 0°C=273°K)

Replacing:

885 torr*V=3.88 mol*62.36365 \frac{L*torr}{mol*K}*301°K

Solving:

V=\frac{3.88mol*62.36365 \frac{L*torr}{mol*K} *301K}{885 torr}

V=82.3 L

<u><em>Its volume is 82.3 L</em></u>

Using the equation below, if you have 4.3 mol of nitrogen tribromide and
ankoles [38]

Answer:

sodium hydroxide is the limiting reactant

Explanation:

The first step is usually to put down the balanced reaction equation. This is the first thing to do when solving any problem related to stoichiometry. The balanced reaction equation serves as a guide during the solution.

2NBr3 + 3NaOH = N2 + 3NaBr + 3HOBr

Let us pick nitrogen gas as our product of interest. Any of the reactants that gives a lower number of moles of nitrogen gas is the limiting reactant.

For nitrogen tribromide

From the balanced reaction equation;

2 moles of nitrogen tribromide yields 1 mole of nitrogen gas

4.3 moles of nitrogen tribromide will yield 4.3 ×1/ 2 = 2.15 moles of nitrogen gas

For sodium hydroxide;

3 moles of sodium hydroxide yields 1 mole of nitrogen gas

5.9 moles of sodium hydroxide yields 5.9 × 1/ 3= 1.97 moles of nitrogen gas

Therefore, sodium hydroxide is the limiting reactant.

The backbone in a nucleic acids strand is called:
Nina [5.8K]

Answer: Option (c) is the correct answer.

Explanation:

Backbone in a nucleic acids strand is made up of sugar molecules attached with phosphodiester bond.

This sugar-phosphate linkage helps in joining of nucleotides in a DNA sequence. Due to this backbone structural framework of nucleotides is formed. In DNA, the sugar is deoxyribose.  

Thus, we can conclude that the backbone in a nucleic acids strand is called sugar backbone.
