How many electrons does an ion of magnesium have if it’s represented by the symbol shown below? 25Mg2+

Chemistry
1 answer:
Galina-37 [17]3 years ago
7 0

Answer:

10 electrons.

Explanation:

Hello!

In this case, since a normal atom of magnesium has 12 protons and electrons when is not in the form of a cation, since it is a metal that tends to lose electrons when ionized, and therefore it becomes positively charged, we infer  that in form of:

Mg^{2+}

It only has 10 electrons.

Best regards!

trapecia [35]
When multiplying by a constant, raise Kp to the power of that constant.

When the reaction is reversed, it gives the inverse of Kp.

Kp^(-1/2) = (7.8 x 10^-16)^(-1/2) = 3.6 x 10^7

When Wolverine’s 10-pound adamantium claws are dissolved in 100 mL of 10 M nitric acid, 10.7 grams of adamantium nitrate are rec
Mazyrski [523]

The percent yield is 71.3 %.

Explanation:

Percent yield is the measure to analyze the success percentage of any experiment .The percent yield of any experiment can be obtained by the ratio of actual or experimental value to expected or theoretical value multiplied with 100.

Percent Yield = \frac{Experimental Outcome}{Theoretical Outcome} *100

So, in the present problem, we have obtained 10.7 g of adamantium nitrate from Wolverine's 10 pound claws. So the actual value or the experimental value is the amount of adamantium nitrate obtained from Wolverine's claws.

Thus, the experimental outcome is 10.7 g. While we had expected to recover 15 g of adamantium nitrate. So the theoretical outcome is 15 g.

Percent yield = \frac{10.7}{15} * 100 = 71.3 %

Thus, the percent yield is 71.3 %.
