Answer: 0.8g/cm^3
Explanation:
In seeing your problem, I see an issue with your units for centimeter. The volume is in the third dimension, so we use cm^3 every single time for the volume. That way, we can arrive to the correct density (in g/cm^3)
Density = mass/volume and so
Density = 8g/10cm^3
= 0.8g/cm^3
Answer:
The volume of the gas will be 78.31 L at 1.7 °C.
Explanation:
We can find the temperature of the gas by the ideal gas law equation:
Where:
n: is the number of moles
V: is the volume
T: is the temperature
R: is the gas constant = 0.082 L*atm/(K*mol)
From the initial we can find the number of moles:
Now, we can find the temperature with the final conditions:
The temperature in Celsius is:
Therefore, the volume of the gas will be 78.31 L at 1.7 °C.
I hope it helps you!
Rock that has formed by sediment deposited by water or air
D. impermeable rocks
Explanation:
Impermeable rocks is the factor among the give choices that will increase the amount of water runoff on the surface.
Surface run-off is liquid water that flows and moves on the earth surface.
- An impermeable rock is a rock that lacks porosity and permeability.
- Porosity is the amount or percentage of void spaces in rock.
- Permeability is the inter-connectivity of the pores.
- When a rock is impermeable, it will not allow water to infiltrate.

Answer:
In He2 molecule,
Atomic orbitals available for making Molecular Orbitals are 1s from each Helium. And total number of electrons available are 4.
Molecular Orbitals thus formed are:€1s2€*1s2
It means 2 electrons are in bonding molecular orbitals and 2 are in antibonding molecular orbitals .
Bond Order =Electrons in bonding molecular orbitals - electrons in antibonding molecular orbitals /2
Bond Order =Nb-Na/2
Bond Order =2-2/2=0
Since the bond order is zero so that He2 molecule does not exist.
