In order to calculate for the amount of CaCl2 and water used we need to multiply the total amount mixture to the percentage of each component. Since we are given a two component mixture CaCl2-water with 40% CaCl2 by mass, therefore we have 60% water.
Amount of CaCl2 = 0.40*(370.9) =148.36 g of CaCl2
Amount of Water = 0.60*(370.9) = 222.54 g of Water
Answer:
Prop-1-yn-1-ide
Explanation:
In this case, we will have an <u>acidic hydrogen</u> upon the left carbon in the alkyne. In the presence of a<u> base</u>, we can <u>remove</u> this hydrogen. In this reaction the base will be 
. The <u>amidure ion</u> will remove the hydrogen of the alkyne to produce a <u>carboanion</u>. (See figure)
Answer: Surface Tension
(Water molecules are attracted to the molecules in the wall of the glass beaker).
Answer: I am not sure but I think its fossil fuel - filling oil and mining coal cause few environmental problems,not dependent on weather condition, not chemical hazard or flammable hazard. Wind and solar - inexpensive, increase carbon footprint and easily stored and transported
Explanation:
I am not quite sure for two of them
