Answer:
14,250 years old.
Explanation:
First, multiply the two lifetimes. - 11,400.
Then, divide 5,700 in half for the 0.5 lifetime. - 2,850.
Lastly, add them all up. - 11,400 + 2,850 = 14,250 years old.
sorry if incorrect <3
thats what i understood XD
The lead acid battery produces energy by oxidation of lead. The amount of lead oxidized in this case is 1.47 g.
<h3>What is lead acid battery?</h3>
The lead acid battery is the common accumulator that we have in use. It is made up of a cell that contains lead electrodes in an acid.
The oxidation of lead occurs according to thr equation;
Pb(s) ----> Pb^2+(aq) + 2e
If 207 g of Pb is oxidized by 2(96500)C
x g of lead is oxidized by (221 * 6.20) C
x = 207 g * (221 * 6.20) C/2(96500)C
x = 1.47 g

It is tasteless and colorless.
L
mol/dm³ is measure for molarity
Answer:
0.72 M
Explanation:
Given data
- Initial volume of the H₂SO₄ solution (V₁): 200 mL
- Volume of water added (VH₂O): 300 mL
- Initial concentration of the H₂SO₄ solution (C₁): 1.8 M
Step 1: Calculate the final volume (V₂)
The final volume of the solution is equal to the sum of the initial volume of the solution and the volume of water.
Step 2: Calculate the concentration of the diluted solution (C₂)
We will use the dilution rule.
