N= m/v n=0.077/.200 = 0.385
Answer:
sodium carbonate decahydrate
Explanation:
Usually we would the molar mass of Na2CO3 x 10 H2O. This is where the name comes from.
Answer:
Without the respiratory system your blood would be useless. The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body
Explanation:
Answer:
0.861842
Explanation:
One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Example #1: Convert 0.875 atm to mmHg. Solution: multiply the atm value by 760.0 mmHg / atm.
Mg + HNO3 -> Mg(NO3)2 + H2
On reactants side:
Mg=1
H=1
N=1
O=3
On products side:
Mg=1
H=2
N=2
O=6 (3×2)
Therefore to balance the equation, we must add 2 to HNO3 on the reactants side...
Mg + 2HNO3 -> Mg(NO3)2 + H2
Reactants:
Mg=1
H=2
N=2
O=6
Therefore, it's balanced.
