Answer:
tap water Is the pure substance
Answer:
a. the conversion of nitric oxide into elemental nitrogen and oxygen gas.
Explanation:
Hello,
In this case, combustion at the automobiles' motors is not complete since gasoline usually has a considerable nitrogen oxides content (NOx) which is highly toxic when giving off from the cars. For that reason, recent advancements have shown platinum-rhodium-based catalytic converters have the capacity to catalyze the conversion of nitrogen oxides to elemental nitrogen and oxygen which are nontoxic. For that reason, answer is a. the conversion of nitric oxide into elemental nitrogen and oxygen gas.
Regards.
525L
Explanation:
Given parameters:
Volume to Temperature ratio = 1.75
Temperature = 300k
Unknown:
Volume of the gas = ?
Solution:
We must carefully analyze and comprehend the detailed description of this experiment:
It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.
This implies that the pressure in the vessel is constant
This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.
Mathematically;
V and T are the volume and temperature
Now we can solve the given problem;
= 1.75
Since temperature is given as 300K
Input the variables:
= 1.75
V = 1.75 x 300 = 525L

Answer:
Structural formula
Explanation:
This is because structural formula is use to show or indicate chemical bonds that are present between atoms of molecules. structural formula comprises of symbols that represent the atoms which are connected by short lines which indicate the presence chemical bonds which could be single line, double lines or even triple lines.
