Answer:245.088
Explanation: you subtract final temperature with initial temperature = 46 then multiply by grams = 552 then multiplied by J = 245.088
There are 2.5 oxygen for every phosphorus atom.
Answer:
Option D. 3, 1, 3, 1
Explanation:
From the question given above,
HNO₃ + Al(OH)₃ —> HOH + Al(NO₃)₃
The equation can be balance as follow:
HNO₃ + Al(OH)₃ —> HOH + Al(NO₃)₃
There are 3 atoms of N on the right side and 1 atom on the left side. It can be balance by 3 in front of HNO₃ as shown below:
3HNO₃ + Al(OH)₃ —> HOH + Al(NO₃)₃
There are a total of 6 atoms of H on the left side and 2 atoms on the right side. It can be balance by 3 in front of HOH as shown below:
3HNO₃ + Al(OH)₃ —> 3HOH + Al(NO₃)₃
Now, the equation is balanced.
Thus, the coefficients are 3, 1, 3, 1
Biotic Resources are based on living organisms. These are obtained from
the biosphere. Examples are animals, birds, forests. They can reproduce
themselves!
Abiotic Resourcesare based on non-living organisms. They are obtained
from lithosphere, atmosphere and hydrosphare. Examples are water, air,
minerals. They cannot reproduce themselves.
Answer:
ZnCO3 + 2HClO4 = Zn(ClO4)2 + CO2 + H2O
Explanation:
ZnCO3 + 2HClO4 = Zn(ClO4)2 + H2CO3
ZnCO3 + 2HClO4 = Zn(ClO4)2 + CO2 + H2O
