Barometer, it is used to measure air pressure
Answer :
The complete equation for the reaction of sulfuric acid and sugar is,

By the stoichiometry of the reaction,
1 mole of sucrose react with the 11 moles of sulfuric acid to give 12 moles of carbon and 11 moles of water.
In this reaction, sulfuric acid react with sucrose (sugar). It dehydrates the sugar molecules which means it eliminates the water.
Because on both of them you are typing/writing something.

Explanation:
so i would,WITH CONFIDENCE C.
Answer:
52.54 %
Explanation:
Half life = 29 years
Where, k is rate constant
So,
The rate constant, k = 0.023902 hour⁻¹
From 1964 to 1991:
Time = 27 years
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
So,
<u>The strontium-90 remains in the bone = 52.54 %</u>
