Explanation:
They are called or known as cations
Answer:
A molecule that has only nonpolar bonds and no polar bonds cannot be polar.
Explanation:
However, a molecule that CONTAINS nonpolar bonds is different, because it can contain polar bonds. A molecule that contains nonpolar bonds can be polar as long as it also contains polar bonds.

The reactant in a chemical reaction that limits the amount of product that can be formed. The reaction will stop when all of the limiting reactant is consumed
Chromium is a fairly active metal. It does not react with water, but reacts with most acids. It combines with oxygen at room temperature to form chromium oxide (Cr 2 O 3 ). Chromium oxide forms a thin layer on the surface of the metal, protecting it from further corrosion (rusting).
Answer:
1720.8g water are necessaries
Explanation:
Mass percent is defined as the mass of solute (In this case, MgCl2) in 100g of solution (Mass MgCl2 + Mass water). To solve this question we must find the mass of solution that we need to produce th 1.5% by mass solution. Thus, we can find the mass of water that we need as follows:
<em>Mass solution:</em>
26.2g MgCl2 * (100g Solution / 1.5g MgCl2) = 1747g solution
<em>Mass water:</em>
1747g solution - 26.2g MgCl2 = 1720.8g water are necessaries
