Answer:
Explanation:
P = 2.35g
Cl= 0.539 g
% MASS = mass of X/ mass of a compound
% mass of P = 2.35 / (2.35+ 0.539) = 81.34%
% mass of Cl = 0.539 /(2.35+ 0.539) = 18.66 %
If the power is out long enough even the city folks will run out of water. Many homes are all electric, so as soon at the lights are out they have no heat, no hot water and they can't cook. ... If the power is out, gas stations can't pump gas. Once generators run out of gas, those people will be in the dark too.
Telling the teacher about a chemical spill immediately
To determine the heat or energy needed for the process, we use the equation,
H = mcpdT
where m is the mass, cp is the specific heat and dT is the temperature difference.
H = (95.4g)(0.44 J/g°C)(32°C - 22°C)
= 419.76 J
Thus, the amount of heat that should be ABSORBED is approximately 419.76 J.
