Answer:
2Na=Ca(OH)000.1 AgBr=2KF 2KBr=LiNO
Answer:
18.9 moles
Explanation:
We have the following data:
V = 50 L
P = 12.4 atm
T= 127°C + 273 = 400 K
R = 0.082 L.atm/K.mol (it is the gas constant)
We use the ideal gas equation to calculate the number of moles n of the gas:
PV = nRT
⇒ n = PV/RT = (12.4 atm x 50 L)/(0.082 L.atm/K.mol x 400 K) = 18.9 mol
Answer 2325 milligrams.
Explanation:The unit is abbreviated as tsp. Convert Milligrams (mg) to Teaspoons (tsp): 1 mg is approximately equal to 0.0002 tsps. One milligram is a relatively small quantity of table sugar A mere one-teaspoon of granulated sugar contains some 2325 milligrams.

The type of energy do chemical bonds have, and the type of energy is it converted to during chemical reactions are that chemical bonds have potential energy, which is converted to heat energy during chemical reactions.
Answer: Option D
Explanation:
The chemical molecules which are bonded by atoms to form such molecule in its stable form consists of chemical potential energy. The potential energy is form of energy which is possessed by the bond, atom or molecule in its non excited or stable state.
As the chemical bonds are stable in nature, they consist of Chemical potential energy. The potential energy of bond converts into heat energy as the bond on breakage either takes up energy to break the bond or releases the heat to break the bond, during the chemical reactions occurring.
