Answer:
1.2 ( two significant digits)
Explanation:
5.4 - 4.21 answer should only have the the number of significant digits as the number in the equation with the least number of significant digits... in this case 5.4 is only two significant digits....so the answer should only have two significant digits
5.4 - 4.21 = 1.19 round to two digits = 1.2

Answer: Some of the chemical energy in natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.
Explanation:
The natural gas consists of chemicals, which when burn produces thermal energy. This thermal energy is utilized for heating or boiling water. The boiling water produces steam the steam tries to come out of the kettle thus makes sound over the kettle lid, the pressure created by steam while leaving kettle produces sound energy.
Hey there!:

Answer 5
Hope this helps !
<u>Ans: P = 22.5% and Cl = 77.5%</u>
<u></u>
<u>Given:</u>
Total Mass of sample containing P and Cl = 50.51 g
Mass of P produced = 11.39 g
<u>To determine:</u>
Mass % of P and Cl
<u>Explanation:</u>
Mass % of a given element in a total mass is generally expressed as:
Mass % of element = [mass of element/total mass]*100
Here,
Total mass = mass of P + mass of Cl
mass of Cl = Total - mass of P = 50.51-11.39 = 39.12 g
% P = [11.39/50.51]*100 = 22.5%
%Cl = [39.12/50.51]*100 = 77.5%
