B. false is the answer of this question
Answer:
0.193 L
Explanation:
Another way of writing the question would be: What volume of a 7.5 M Sodium Bromide solution would contain 1.45 moles.
To answer that we can use the <em>definition of molarity</em>:
- Molarity = moles / liters
We <u>input the given data</u>:
- 7.5 M = 1.45 moles / liters
And <u>calculate how many liters are required</u>:
- 1.45 mol / 7.5 M = 0.193 L
The shorthand equation shows us in a glance what happens in the electrochemical reaction. For a lead storage battery, we have; PbSO4(s)/H2O//Pb (s) ,PbO2(s) /H2SO4
<h3>What is an electrochemical reaction?</h3>
An electrochemical reaction is one in which electrical energy is produced from a chemical reaction. The equations in a lead storage battery are;
Anode: Pb (s) + HSO4- → PbSO4(s) + H+ + 2 e-
Cathode: PbO2(s) + HSO4- + 3 H+ + 2 e- → PbSO4(s) + 2 H2O
Overall: Pb (s) + PbO2(s) + 2 HSO4- + 2 H+ → 2 PbSO4(s) + 2 H2O
Hence, the shorthand notation of this reaction is;
PbSO4(s)/H2O//Pb (s) ,PbO2(s) /H2SO4

Answer:
H2O is the chemical formula for water or in simple language its is water
Explanation:
<span>(2) a diatomic molecule is the correct answer.
When two atoms of Br bond together, they will form bromine gas with a chemical formula of Br2. Therefore, it is called a diatomic molecule. (the word "di" means two).
Hope this helps~
