Answer: 
Explanation:
Heat of combustion is the amount of heat released when 1 mole of the compound is completely burnt in the presence of oxygen.

To calculate the moles, we use the equation:
Thus
of sucrose releases = 916.6 J of heat
1 mole of sucrose releases =
of heat
Thus ∆H value for the combustion reaction is 
Two because it has six electrons in it's valence shell and it still has space for two more
Answer:
A combustion reaction
Explanation:
C
organic compound(contains carbon) reacts with oxygen to give out carbon dioxide and water is a complete combustion.
Answer:
The Coriolis effect is caused by the rotation of the earth around its own axis.
Explanation:
The Coriolis effect arises from the fact that different latitudes of the earth's surface rotate at different speeds. The path of wind on earth is deflected by the Coriolis effect. As things move over the earth, they meet different speed areas, which causes the Coriolis Effect to divert their route.
Thus, The Coriolis effect is caused by the rotation of the earth around its own axis.
Answer:
the molarity of MgCl2 = 6.073 x 10^-2 M
Explanation:
Molarity = mole (n) divided by volume of solution (V) in liter = n/v
mole (n) = mass (m) divided by molecular mass (Mm) = m/Mm
n of MgCl2 = 2.891/95.3 = 0.03033 mole
v of solution = 500 ml = 0.500 L
Molarity = n/v = 0.03033/0.500 = 0.06066 M = 6.07 x 10^-2 M
