Answer:

Mass = 30 g

Explanation:

Given data:

Mass of hydrogen needed = ?

Number of moles of ammonia produced = 10 mol

Solution:

Chemical equation:

N₂ + 3H₂        →      2NH₃

Now we will compare the moles of ammonia and hydrogen.

                  NH₃            :                H₂

                    2               :                3

                   10               :               3/2×10 = 15 mol

Mass of hydrogen needed:

Mass = number of moles × molar mass

Mass = 15 mol × 2 g/mol

Mass = 30 g

weqwewe [10]

The low temperature outside lowers the volume of the gas according to Charles' law because this law describes how a gas will behave at constant pressure. It shows that the volume of a given mass of a gas is directly proportional to the absolute temperature provided the pressure remains constant. An increase in temperature leads to an increase in volume while a decrease reduces the volume. This is due to the reduction in the distances traveled by the vibrating  particles of the gas because of the lost kinetic energy.

If Maria winks exactly 5 times every minute and she sleeps
Elina [12.6K]

First, we need to find the amount of winks in an hour, to simplify it so we can answer easier. Since there are 60 minutes in an hour, we can multiply 5 by 60 to find the number of winks in an hour.

5*60=300

Now multiply 300 by 8.

300*8=2,400

She winks exactly 2,400 times per day.

Hope this helps!

belka [17]
<span>In the field of science, usually, the product of an experiment is computed ahead to understand if it reached a specific objective. It would reach greater than 100% of percent yield if the factors include faster reaction rates; proper handling of the reactants, no outside contaminants, and the procedure of the experiment is followed smoothly. It would reach lesser than 100% percent yield if the experiment is not followed, external factors such as contamination from the environment (wind, moisture, etc). </span>
