Answer:
Lithium
Explanation:
Alkali metals are group of metals which are present in first group of periodic table. As we know atomic number is equal to number of protons contained by a particular element. Therefore, the alkali metals along with there number of protons are listed below;
Alkali Metal Number of Protons
Lithium 3
Sodium 11
Potassium 19
Rubidium 37
Cesium 55
Francium 87
Hence, it is cleared from above table that Lithium is having fewer protons than 10.
Answer:
6.52 × 10^14 Hz
i don't know if that's right tbh
The balanced chemical reaction is written as:
<span>Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)
</span>
We are given the amount of the reactant zinc to be used in the reaction This amount would be the starting point for the calculation. It is as follows:
5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) (2.02 g H2 / 1 mol H2 ) = 10.1 g H2
Therefore, the correct answer is the second option.
Having food in your stomach does not allow to keep alcohol from being absorbed but it does allow you to not get intoxicated as fast. this is a (FACT)!!!!
The answer would be Ca + FeN = Ca3N2 + 2Fe
