Answer:
Density can be useful in identifying substances. It is also a convenient property because it provides a link (or conversion factor) between the mass and the volume of a substance. Mass and volume are extensive (or extrinsic) properties of matter - they depend on amount.
Explanation:
Answer:
449.5 g
Explanation:
Silver sulfate- Ag2SO4
M(Ag)=107 g/mol => M(Ag2)=214 g/mol
M(S)=32 g/mol
M(O)=16 g/mol => M(O4)=64 g/mol
M(Ag2SO4)=310 g/mol
n=1.45 mol
m(Ag2SO4)=M(Ag2SO4)*n=310 g/mol *1.45 mol= 449.5 g
True, Robert Hooke was the first person to discover cells inside a cork.
Answer: The given question is incomplete. The complete question is:
At a certain temperature the rate of this reaction is second order in 
with a rate constant of 
. 
Suppose a vessel contains at a concentration of 0.100 M Calculate how long it takes for the concentration of to decrease to 0.0240 M. You may assume no other reaction is important. Round your answer to 2 significant digits.
Answer: It takes 0.93 seconds for the concentration to decrease to 0.0240 M.
Explanation:
Integrated rate law for second order kinetics is given by:
= initial concentration = 0.100 M
a= concentration left after time t = 0.0240 M
k = rate constant =
t = time taken for decomposition = ?
Thus it takes 0.93 seconds for the concentration to decrease to 0.0240 M.
