<u>First part:</u>
2 atoms of Na
6 atoms of N
<u>Second part:</u>
2 atoms of N
2 atoms of Na
Why?
We are given the chemical reaction, so, we can extract the number of atoms for both reactants and products.
We are given the chemical equation:
We can rewrite it as follow:
From the reactants, we have:
From the products we have:
Hence, we have that:
There are <u>6 atoms of N in the reactants</u> and <u>6 atoms of N in the products.</u>
and
There are <u>2 atoms of Na in the reactants</u> and<u> </u><u>2 atoms of Na in the products</u> since we have a balanced equation.
Have a nice day!
The total mass is the sum of the masses.
It is
5543 + 23.45 + 697.4 mg = 6263.85 mg
Answer: 6263.85 mg
A barometer is used to measure the pressure in the air, Like if there was a Storm coming the barometer can forecast (Predict) The weather in the air
The answer is b because 46-44 = positive 2.
Answer:
<h2>The answer is 1.48 L</h2>
Explanation:
In order to find the original volume we use the same for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the original volume
From the question
P1 = 172 kPa = 172000 Pa
P2 = 85 kPa = 85000 Pa
V2 = 3 L
We have
We have the final answer as
<h3>1.48 L</h3>
