Answer: The correct answer is option D.
Explanation:
Mass of the NaCl = 225 g
Volume of the solution ,V = 0.25 L
15.4004 mol/L is the molarity of the solution. The most closest option to our answer is option D.
Yes it does, its derived from the greek name for beryl, or beryllo
Answer:
A chemical reaction expresses a chemical change. For example, one chemical property of hydrogen is that it will react with oxygen to make water. We can write that as follows:
hydrogen reacts with oxygen to make water
We can represent this chemical change more succinctly as
hydrogen + oxygen → water
where the + sign means that the two substances interact chemically with each other and the → symbol implies that a chemical reaction takes place. But substances can also be represented by chemical formulas. Remembering that hydrogen and oxygen both exist as diatomic molecules, we can rewrite our chemical change as
H2 + O2 → H2O
A process called respiration. This process is carried out in organelles in the cell<span> called the Mitochondria.</span>
If I had to answer, I would go with C.) Two elements in the same group
I would choose C because elements in the same group have the same number of valence electrons. When elements have the same number of valence electrons, they are all willing to give/receive them in the same way. Therefore, if placed in water, they will combine with water the same way.
Hope this helps!
