The statement "<span>All gaseous mixtures are solutions." is true. This is because there are a number of gaseous molecules present in a volume of gas and they are considered solutions.</span>
Answer:
0.0055 seconds
Explanation:
To answer this question you need to know the equivalence:
1 second (s) = 5.5 (miliseconds) (ms)
Then you use the conversion factor:
-Put the value given and the units:
- Put in the denominator the equivalence with the same units:
- Put in the numerator the unit at which you want to convert the value given:
- Then multiply and divide the quantities:
Note that the same units in numerator and denominator are cancelled.
Answer:
There is 1.6 L of NO produced.
Explanation:
I assume you have an excess of NH3 so that O2 is the limiting reagent.
<u>Step 1:</u> Data given
2.0 liters of oxygen reacts with ammonia
<u>Step 2:</u> The balanced equation
4NH3 + 5O2 → 4NO + 6H2O
For 4 moles of NH3, we need 5 moles of O2 to produce 4 moles of NO and 6 moles of H2O
Consider all gases are kept under the same conditions for pressure and temperature, we can express this mole ratio in terms of the volumes occupied by each gas.
This means: when the reaction consumes 4 liters of ammonia (and 5 liters of oxygen) it produces 4 liters of nitrogen monoxide
Now, when there is 2.0 liters of oxygen consumed, there is 4/2.5 = 1.6 L of nitrogen monoxide produced.
There is 1.6 L of NO produced.
The answer is c because the subject thinks that they will be shocked when then might not
