Answer:Precision can be defined as the. reproducibility of a measured value. Precision is how close the measured values are to each others. In contrast with accuracy, accuracy is the agreement between a measured value and an accepted value.
Explanation:
<h2>
Hello!</h2>
The answer is: The new pressure of the gas is 3.6 atm.
<h2>
Why?</h2>
From the statement we know that the gas is kept at a constant temperature of 0°C, so, if the gas keeps a constant temperature we can use the Boyle's Law to solve this problem.
The Boyle's Law states that:

Where,
P is the pressure of the gas.
V is the volume of the gas.
So, the given information is:

Now, substituting it into the Boyle's Law equation to calculate the new pressure, we have:

So, the new pressure is 3.6 atm.
Have a nice day!
Answer:
Explanation:
You just have to see the REACTANTS and PRODUCTS and look how much molecules are there and accordingly put numbers.
Eg:4Fe+3O2--------->2Fe2O3
