For the chemical reaction:
Julli [10]

Answer:

Volume of ammonia produced = 398.7 dm³

Explanation:

Given data:

Volume of N₂ = 200 dm³

Pressure and temperature = standard

Volume of ammonia produced = ?

Solution:

Chemical equation:

N₂ + 3H₂     →      2NH₃

Number of moles of N₂:

PV = nRT

1 atm× 200 L = n× 0.0821 atm.L/mol.K × 273 K

n = 200 atm.L /22.41 atm.L/mol

n = 8.9 mol

Now we will compare the moles of ammonia and nitrogen.

               N₂          :         NH₃

                1            :           2

              8.9          :        2/1×8.9 = 17.8 mol

Volume of ammonia:

1 mole of any gas occupy 22.4 dm³ volume

17.8 mol ×22.4 dm³/1 mol = 398.7 dm³

Balance the following skeleton reaction and identify the oxidizing and reducing agents: H2S(g) + NO3 ---->’ S8(s) + NO(g) [ac
disa [49]

Answer : Oxidizing agent is NO^-_3 and Reducing agent is H_2S

Explanation :

The given unbalanced redox reaction is,

H_2S(g)+NO^-_3(aq)\rightarrow S_8(s)+NO(g)

In acidic medium, the balanced redox reaction is,

24H_2S(g)+6NO^-_3(aq)16H^+(aq)\rightarrow 3S_8(s)+16NO(g)32H_2O(l)

Oxidizing agent : Oxidizing agents are those agent which oxidizes other substance and itself get reduced.

Reducing agent : Reducing agents are those agent which reduces other substance and itself get oxidized.

In this redox reaction, NO^-_3 is an oxidizing agent and H_2S is a reducing agent.

The redox reaction is also shown below.

a sample of substance has a volume of 60.5 ml and a density of 1.20g/ml. what is the mass of the sample?
Sliva [168]

The mass of a sample of substance with a volume of 60.5 ml and a density of 1.20g/ml is 72.6 g.

Density, denoted as ρ, is a physical property of a material which is defined as the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" or compact an object has in a unit volume. The more dense a substance is, the heavier it feels for its size.

To find the density, use the formula given by:

ρ = \frac{m}{v}

where

ρ = density

m = mass

v = volume

Using the same formula, we can transform it to solve for mass, if the volume and density are given.

ρ = \frac{m}{v}

m = ρv

Putting the values in,

m = 1.20g/ml x 60.5 ml

m = 72.6 g

Hence, the mass of a sample of substance with a volume of 60.5 ml and a density of 1.20g/ml is 72.6 g.
