From ideal gas equation that is PV=nRT
n(number of moles)=PV/RT
P=760 torr
V=4.50L
R(gas constant =62.363667torr/l/mol
T=273 +273=298k
n is therefore (760torr x4.50L) /62.36367 torr/L/mol x298k =0.184moles
the molar mass of NO2 is 46 therefore density= 0.184 x 46=8.464g/l
Answer:
it is 50
if I m right pls mark me brainliest
True
Explanation:
Magnetism is the ability of a material to be attracted by a magnet or to act like a magnetic material.
- Magnetism is exhibited by a wide range of substances.
- In fact, the earth behaves like a bar magnet.
- A magnet usually have a magnetic field round them and they exert their forces in this regions.
- Magnets are used for a wide range of functions like in fans and rotors.
- Substances can lose their magnetic ability when exposed to high temperatures and electrically.

Energy from SUNLIGHT + CO2(g) + H2O(l) = C6H12O6 (glucose) + O2(g)
The above is unbalanced, but it shows that sunlight is on the left side of the equation.
Sunlight provides the energy for the reaction to take place, without it nothing would really happen. Therefore it is an INPUT into the equation, thus it is on the left side. Outputs are placed on the right side of the equation.
