Identify ALL the possible mol ratio from this balanced equation:

Karolina [17]

There are 3 possible mole ratios

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

N₂(g)+3H₂(g)⇒2NH₃

So mol ratio :

N₂:H₂:NH₃=1:3:2

Possible mol ratio :

1 mole N₂

3 mol H₂

2 mole NH₃

3 mole H₂

1 mole N₂

2 mole NH₃

If 3.25 g N2 gas is introduced into an evacuated 1.50 L flask at 325 K, what is the pressure

Volgvan

Answer:

2.06 atm

Explanation:

The computation of the pressure inside the flask is shown below;

As per the ideal gas law

we know that

P V = nRT

where

V = 1.50L

T = 325 K

R = 0.0821

Now moles of N_2 is

= 3.25 ÷ 28

= 0.116 mol

Now

P = NRT ÷ V

= 0.116 × 0.0821 × 325 ÷ 1.50

= 2.06 atm

If 1495 J of heat is needed to raise the temperature of a 319 g sample of a metal from 55.0°C to 66.0°C, what is the specific he

Olegator [25]

The specific heat capacity of the metal is calculated using the following formula
Q(heat)= MC delta T
Q= 1495 j
c= specific heat capacity =?
M(mass)=319 g
delta T = change in temperature = 66-55 =11 c
by making c the subject of the formula

C=Q /M delta T
c= 1495 j/ 319 g x 11 c =0.426 j/g/c
