Answer:
The answer should be A:) The energy produced from the splitting of atoms.
Explanation:
It is TRUE that mass is indeed the gravitational force that pulls on earth
The percent by mass of an answer made from 14 g NaCl (the solute) and 61 g water is 18.66%
14 g + 61 g =75.0 g - mass of the solution
mass % = (mass solute/ mass solution)*100% = (14/75.0)*100% =
= 0.186*100% =18.66%.
What is the percent by mass?
Mass percent is another method of expressing the composition of the solution mixture. It describes the amount of solute (grams) present in 100 gm of the solution.

CaSO4(s) might be an improperly capitalized: CAsO4(S), CaSO4(S)
Balanced equation:
K2SO4(aq) + CaI2(aq) = CaSO4(s) + 2 KI(aq)
Reaction type: double replacement.
Answer: E. trigonal planar
Explanation:
The trigonal planar geometry is made up of 3 equally spaced sp2 hybrid orbitals arranged at angle 120° to each other, The molecule are electron deficient and does not follow octet rule. Therefore, a molecule containing an sp2 hybrid central atom has a trigonal planar geometry e.g boron hydride (BH3)
