Answer:
tiny crystals of the mineral quartz, which is made out of silica and oxygen
Good conductors of electricity and heat, form cations by loss of electrons,
Answer:
power is work/time so 10,000j/5s=2000J/s
Yes because without movement the tow truck will not be moved with 15,000 N
The answer is: 1.5 moles of oxygen are present.
V(O₂) = 33.6 L; volume of oxygen.
p(O₂) = 1.0 atm; pressure of oxygen.
T = 0°C; temperature.
Vm = 22.4 L/mol; molar volume at STP (Standard Temperature and Pressure).
At STP one mole of gas occupies 22.4 liters of volume.
n(O₂) = V(O₂) ÷ Vm.
n(O₂) = 33.6 L ÷ 22.4 L/mol.
n(O₂) = 1.50 mol; amount of oxygen.
