Answer:
will be 90054 J
Explanation:
Number of moles = (mass)/(molar mass)
Molar mass of 
= 134.45 g/mol
So, 1.00 g of = 
of = 0.00744 mol of
0.00744 mol of produces 670 J of heat
So, 1 mol of produces 
of heat or 90054 J of heat
Answer:
Desertification mainly impacts land resources.
Point and nonpoint sources refer to types of water pollution.
The process of people moving to cities, called urbanization , greatly impacts land, air, and water resources.
The burning of fossil fuels can cause smog and acid rain.
Explanation:
Answer:
mass O2 = 222.5 g
Explanation:
- %wt = ((mass compound)/(mass sln))×100
balance reaction:
∴ %wt H2 = 11 % = ((mass H2)/(mass H2O))×100
∴ %wt O2 = 89 % = ((mass O2)/(mass H2O))×100
∴ mass H2O 250 g
⇒ mass O2 = (0.89)(250 g)
⇒ mass O2 = 222.5 g
Answer:-
H+ + OH- --> H2O
Explanation:-
The chemical equation is NaOH + HNO3 --> NaNO3 + H2O
Now for the ionic compounds
HNO3 --> H+ + NO3 -
NaOH--> Na+ + OH-
NaNO3 --> Na+ + NO3-
Water being covalent will remain as H2O,
Hence
HNO3 + NaOH--> NaNO3 + H2O
H+ + NO3 - + Na+ + OH- --> Na+ + No3 - + H2O.
Crossing out common terms
H+ + OH- --> H2O
Answer: But because part 2 stays the same
