Answer:
CaBr2 is a colorless solid and the charge on Calcium is +2
Explanation:
CaBr2 is a colorless solid at room temperature.
Other properties include -
a) It is a crystalline solid
b) Melting point of 765°C.
c) It is deliquescent
d) Soluble in water and absolute alcohol.
The charge of Br is -1. Here two atoms of Br attaches with one atom of calcium. Hence the charge of calcium is +2
Aldehydes are usually more reactive<span> toward nucleophilic substitutions </span>than<span> ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.</span>
The correct answer to
the question that is stated above is letter C.<span>compression and rarefaction
</span>
Longitudinal wave has two features which include:
A compression--<span> the part of the wave which is pressed together.
A </span>rarefaction--<span> the part of the wave that is the most spread apart.</span>
Answer: The mass of oxygen per gram of nitrogen is 0.57
Explanation: Given Mass of Nitrogen (N2) = 30.82 g
Given Mass of Oxygen (O2) = 17.60 g
Thus the mass of oxygen per gram of nitrogen can be calculated by dividing the given mass of the oxygen by the given mass of the nitrogen.
Thus, Mass of oxygen per gram of nitrogen = 17.60 g / 30.82 g = 0.57
Thus the answer is 0.57
