Answer:
He had the most potential energy going down hill
Explanation:
because he picked up he went faster
Explanation:
a) 3Pb(NO3)2 + Al2(SO4)3 ---> 3PbSO4 + 2Al(NO3)3
Double displacement
b) 2Cl2 + 3O2 ---> 2Cl2O3
Synthesis
c) 2Fe2O3 + 3C ---> 4Fe + 3CO2
single displacement
Use the 1st order decay equation

Answer:
34.21%
Explanation:
Given parameters:
Mass of ethylene glycol in the container = 130g
Mass of the liquid in total = 380g
Unkown:
Percentage of ethylene glycol in the liquid =?
Solution
To find the percentage of the ethylene glycol in liquid, we use the expression below:
Percentage of ethylene glycol in liquid =
x 100
Percentage of ethylene glycol =
x 100
Percentage of ethylene glycol = 34.21%
