Answer:
B. SO2
Explanation:
An Ionic bond transfurs electrons and occurs with metals and nonmetals
Covalent is the sharing of electrons and occurs with nonmetals only.
Answer:
"1 M" will be the right solution.
Explanation:
The given values are:
Number of moles,
= 2 moles
Volume of solution,
= 2000 mL
or,
= 2 L
Now,
The molarity of the solution will be:
= ![\frac{Moles}{Liters}](https://tex.z-dn.net/?f=%5Cfrac%7BMoles%7D%7BLiters%7D)
On substituting the values, we get
= ![\frac{2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D)
= ![1 \ M](https://tex.z-dn.net/?f=1%20%5C%20M)
B.
There is no covalent bonds in pure H2O. Only hydrogen
Density is the mass of compound divided by its volume can be shown as follows:
![d = 0.5 g /mL = m /V = m /40 = 0.5](https://tex.z-dn.net/?f=d%20%3D%200.5%20g%20%2FmL%20%3D%20m%20%2FV%20%3D%20m%20%2F40%20%3D%200.5)
![m = 20 g](https://tex.z-dn.net/?f=m%20%3D%2020%20g)
40 mL of snow having 20 g of mass calculated from density.
Now, 10 cm of snow = 3.93 inches = 20 g
As, 10 inches of rain will produce 11 inches of ice as the volume of ice is bigger than rain water.
10 inches rain = 11 inches snow
3.93 inches of snow produced by
![= (3.93 * 10) /11 = 3.57 inches rain.](https://tex.z-dn.net/?f=%3D%20%283.93%20%2A%2010%29%20%2F11%20%3D%203.57%20inches%20rain.)
Thus, 3.57 incehs of rain produces by 10 cm snow.
