How many grams of water can be produced from 4.6 grams of Hydrogen and 7.3 grams of Oxygen?
12345 [234]

Answer:

The answer to your question is 8.21 g of H₂O

Explanation:

Data

mas of water = ?

mass of hydrogen = 4.6 g

mass of oxygen = 7.3 g

Balanced chemical reaction

                   2H₂  +  O₂  ⇒   2H₂O

Process

1.- Calculate the atomic mass of the reactants

Hydrogen = 4 x 1 = 4 g

Oxygen = 16 x 2 = 32 g

2.- Calculate the limiting reactant

Theoretical yield = H₂/O₂ = 4 / 32 = 0.125

Experimental yield = H₂/ O₂ = 4.6/7.3 = 0.630

From the results, we conclude that the limiting reactant is Oxygen because the experimental yield was higher than the theoretical yield.

3.- Calculate the mass of water

                   32 g of O₂ ---------------- 36 g of water

                   7.3 g of O₂ ---------------   x

                          x = (7.3 x 36) / 32

                          x = 262.8 / 32

                          x = 8.21 g of H₂O

motikmotik
Answer-kinetic energy. The human experience of sound is caused by vibrations. The object creating the sound creates waves of movement through a medium, like air, until it reaches our eardrums, which then vibrate and our brain interprets that as sound. Here are some examples of sound energy:

Some gas was collected when the pressure was 760mmHg. It occupied 500mL when the pressure was increased to 800mmHg. What was the
Ivan

Answer:

<h3>The answer is 526.32 mL</h3>

Explanation:

To find the original volume we use the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the original volume

V_1 =  \frac{P_2V_2}{P_1}  \\

From the question we have

V_1 =  \frac{500 \times 800}{760}  =  \frac{400000}{760}  =  \frac{40000}{76}  \\  = 526.315789...

We have the final answer as

<h3>526.32 mL</h3>

Hope this helps you
