percentage of zinc= 5.985/20 X 100= 29.5%
let x represents zinc and y be magnesium so
Zinc(s) + 2HCl(aq) -----> ZnCl2(aq) + H2(g)
Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)
1.152 g of hydrogen gas=( x/65.3 + y/24.305) 20
= 3.08 x10^-2 + 0.8295-8.30
=x=5.985
y= 4.015
percentage of zinc= 5.985/20 X 100= 29.5%
The hydrogen gas escapes, so the two products of Zinc Chloride and Magnesium Chloride will then react with Silver Nitrate. Again, I combine both of the reactions

Answer:
Explanation:
D
A decrease in the outside insect population
The volume of the hydrogen gas would be 116.022 L
<h3>Density</h3>
The density of an object is a measure of how heavy the object is.
Mathematically, the density of an object is given by:
Density = mass/volume.
Thus, given 2 out of the 3 variables that make up the equation, the unknown variable can be calculated.
In this case, the mass and the density of hydrogen were given as 10.326 g and 0.089 g/L respectively.
Therefore, we need to find the volume by making it the subject of the formula from the equation above.
Volume = mass/density.
10.326/0.089 = 116.022 L
This means that the volume of the hydrogen gas is 116.022 L

Answer:
The C22- ion is stable
Explanation:
The C22- ion is a stable ion having a bond order of three. It has a favourable stabilization energy of 6∆ compared to 4∆ in C2. In the carbide ion carbon firms three bonds rather than two in dicarbon, hence the formation of the carbide ion is preferred. The molecular orbital configuration of the carbide ion is shown in the image attached.
