Yes: water can exist in solid (ice), liquid (water), and gas (water vapor) forms.
Answer:
behaviors that are passed down genetically
Answer:
A and E for sure.
Explanation:
Can't be B or C, since it is stated in the problem. And probably not D because candy don't have magnetism to them.

Now, question is why MgO but not CaO.
At a dissociation pressure of 1 atm, the temperature at which CO2 and metal oxide is formed is :
For MgCO3 = 540 °C
For CaCO3 = 900 °C”
Also,
<span>The driving force is the larger lattice energy of MgO(3795) vs that of CaO(3414 kJ mol^-1) . More the lattice energy, the more chances of that compound to form.</span>
So MgO is formed first.
Carbonate is Calcium carbonate
