A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal.
Answer:
Water is most dense as a liquid, then as a solid, and least dense as a gas. Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.
Explanation:
Answer:
11.0 L
Explanation:
The equation for this reaction is given as;
2H2 + O2 --> 2H2O
2 mol of H2 reacts with 1 mol of O2 to form 2 mol of H2O
At STP;
1 mol = 22.4 L
This means;
44.8 L of H2 reacts with 22.4 L of O2 to form 44.8 L of H2O
In this reaction, the limiting reactant is H2 as O2 is in excess.
The relationship between H2 and H2O;
44.8 L = 44.8 L
11.0 L would produce x
Solving for x;
x = 11 * 44.8 / 44.8
x = 11.0 L
The answer is Coal. Atmospheric pollution is least when geothermal electricity is used to produce electricity.
Answer:
The answer to your question is: Arrhenius base
Explanation:
Arrhenius base ; an Arrhenius base is able to produce (OH-) in water, so Ca(OH)2 is an Arrhenius base.
Brønsted-Lowry base
. An Bronsted and Lowry base is able to accept a proton, Ca(OH)2 can do it.
Lewis base
this base is able to donate a pair of electrons, Ca(OH)2 does not have a pair of electrons to donate.
All of the above. This option is wrong only the first option is correct.
