9
Explanation:
cause 2 + 2 is equal to 9
The degree to which a specified material conducts electricity, calculated as the ratio of the card density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.
The reaction between zinc and silver nitrate is

Moles of Zn = m /M = 599 /65 = 9.2 mol
Moles of AgNO3 = m /M = 1500 /169 = 8.87 mol
Silver nitrate is reacting completely to give silver
Thus, moles of Silver nitrate is equivalent to silver = 8.87
For mass of silver produced
m /M = 8.87 = m /107
m = 949.24 g
Hence, the given quantity of reactants are sufficient to produce 800 g of silver as the amount of silver produced is 949.24 g
A. The hydrogen molecule has a structural formal that looks like this: H—H. The oxygen molecule has a structural formula that looks like this: O=O (except you should make the lines longer). When you combine the molecules, it has a structural formula that looks like this:
O
/ \
H H
b. O=C=O (again, make the lines a little longer)
c. space-filling model of hydrogen looks like this oo (circles should be touching) and the space-filling model of carbon dioxide should look like this OoO (circles should be touching)
Answer:
There are there are 8.13-10^25
Explanation:
N(CS2)= 1.35* (times) 6.02-10^ 25= 3.13-10^25 molecules
