Answer:
When these materials end up in the ocean, they support the growth and well-being of marine life.
Explanation:
This is the incorrect statement
Answer:
2.11 g hydrobromic acid (correct to 3SF)
Explanation:
Molecular formula of hydrobromic acid = C2H5BrO2
mass of C2H5BrO2 = 140.96g
Beginning with what we're given, 9.03*10^21 we then make a conversion by using Avegadro's number which is 6.02*10^23 per mole (Oct. 23 at 6:02 am is national mole day :) Then, we need to convert out of moles, 140.96g hydrombromic acid per mole.
It looks like this:
9.03*10^21 molecules • (1 mol C2H5BrO2 / 6.02*10^23 molecules) • (140g C2H5BrO2 / 1 mol) = 2.1144 g C2H5BrO2
Here are the balanced equations
- C_2H_5OH+3O_2--->2CO_2+3H_2O+Energy
- 2AgCl-->2Ag+Cl_2
- AgNO_3+Zn--->Ag+ZnNO_3
- 3BaCl_2+Al_2(SO_4)_3--->3BaSO_4+2AlCl_3
- H_2+I_2--->2HI
Done!
