If a sample of radioactive isotopes takes 60 minutes to decay from 200 grams to 50 grams, what is the half-life of the isotope

Chemistry
1 answer:
qaws [65]3 years ago
6 0

Answer:

<u><em>I HOPE IT WILL BE YOUR ANSWER:</em></u>

Explanation:

As given

60 min = 50 gm        (1)

then we know half-life mean half amount decay time

so we can write as the half of 200 is 100 gm hence

T 1/2 = 100               (2)

solving these two equation by cross multiplication we will get

T 1/2 = 120 min

If 125 g of CaCO3 is mixed and reacted with 125 g of HCl, which reactant is limiting and how many grams of CO2 can be made?
Trava [24]

Answer:

CaCO3 is the limiting reactant

55 g of CO2 is made

Explanation:

First we must put down the reaction equation;

CaCO3(s) + 2HCl(aq) ---------> CaCl2(s) + H2O(l) + CO2(g)

Number of mole of CaCO3 = 125g/100gmol-1 = 1.25 moles

From the reaction equation;

1 mole of CaCO3 yields 1 mole of CO2

Hence 1.25 moles of CaCO3 yields 1.25 moles of CO2

For HCl;

number of moles of HCl = 125g/36.5 g mol-1 = 3.42 moles

From the reaction equation;

2 moles of HCl yields 1 mole of CO2

3.42 moles of HCl yields 3.42 * 1/2 = 1.71 moles of CO2

Hence CaCO3 is the limiting reactant.

Mass of CO2 produced = 1.25g * 44 gmol-1 = 55 g of CO2

Which reaction is a decomposition reaction?
Artist 52 [7]

Answer:

See the answer below , please.

Explanation:

In a decomposition reaction, a certain compound is "broken" to give two or more different products.

An example for compound AB, giving as products A and B:

AB -> A + B

In the case of water:

2H20 -> 2H2 + 02,  water decomposes giving Hydrogen and Oxygen
