The answer is A, light and heat energy.
Answer:
It is MgCl₂ because the total positive charge on Mg is two
Explanation:
The bond between the atoms that makes up the formula unit of the compound is an ionic bond. This bond involves the transfer of electrons between atoms.
Mg is in the second group on the period on the periodic table. It has two valence electrons and would readily lose it to have a stable atomic configuration like those of noble gases. This leaves magnesium with a net positive charge of 2. Each chlorine atom gains one electron to achieve their own octet.
Strawberry, bread, bananas/ lemonade, milk, water/ nitrogen, oxygen, carbon dioxide
See where the liquid or whatever you're measuring meets with the numbers! And thats your answer!
Sugar dissolves and is spread throughout the glass of water<span>. The </span>sand<span> sinks to the bottom. The sugar-</span>water<span> is a homogeneous mixture while the </span>sand-water<span> is a heterogeneous mixture. Both are mixtures, but only the sugar-</span>water<span> can also be called a </span>solution. i got this from :<span>www.chem4kids.com/files/matter_solution.html
