Answer:
tha mass of magnesium nitrate is 592g
Explanation:
from a balanced chemical equation
2HNO3 + Mg(OH)2→ Mg(NO3)2 + 2H2O
2 mol of nitric acid is equivalent to 1 mol of magnesium nitrate. then 8 mol of nitric acid will be equivalent to 4 mol of magnesium nitrate.
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted. This happens because all the heat energy goes into breaking the bonds of the ice's crystal lattice structure.
Explanation:
Answer:the horizontal rows in the periodic table are called periods
Explanation:Btw the vertical ones are called groups or families.
Answer:
Molar mass = 216.8254 (approx.)
Explanation:
Given:
FeCl2 • 5H20
Find:
Molar mass
Computation:
Atomic mass
Fe = 55.845
Cl = 35.453
H = 1.00794
So,
FeCl2 • 5H20
55.845 + 2(35.453) + (2)5(1.00794) + 5(15.999)
55.845 + 70.906 + 10.0794 + 79.995
Molar mass = 216.8254 (approx.)
Answer:
A. car moving down the highway
Explanation:
Potential energy is when the energy is being held in, as in, it is very still, and not moving.
When a car is moving down a highway, it is releasing kinetic energy, instead of potential.
