Answer:
Option C. 0.34 moles
Explanation:
Data obtained from the question include:
Molarity = 0.15M
Volume = 2.25L
Mole =
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 0.15 x 2.25
Mole = 0.34mole
The number of mole of AlCl3 present in the solution is 0.34mole.
Answer is: product of reaction.
<span>There are two types
of reaction: endothermic reaction (chemical reaction that absorbs more
energy than it releases) and exothermic reaction (chemical reaction that
releases more energy than it absorbs).
</span><span>According to
Le Chatelier's principle when the reaction is exothermic heat is
included as a product.</span>
It would change the charge, a neutral atom has zero charge but a proton has a positive charge. So 0 charge + 1 positive charge = 1 positive charge.
Answer:
The shape of a molecule is mostly determined by repulsion among the pairs of electrons around a central atom.
Answer:
Gas, has no shape but does take up volume
