In order to balance this equation you need to count each element and how many of the individual elements are in the equation. _H2+N2=2 NH3 You multiply the 2 (Which is the coefficient) by the 3 (which is the subscript) This would equal 6 which indicated there are 6 hydrogen atoms on the right side so the left side should also have 6 hydrogen atoms
The missing coefficient on the left side must multiple the 2 to become 6 hydrogen Answer=3
Answer:
Is when there is an increase in the temperature of the liquid
Explanation:
Increase in temperature of the liquid is an indication that chemical change occur because chemical change occur through process of chemical reaction and it involve when two or more substances combine together to form new substances which is as a result of change in chemical composition. The crystals dissolved in water to form another new solution and it became warm and this indicate a chemical change, new substances are formed as a result of increase in temperature.
One mole of an ideal gas will occupy 22.4 liters of volume at STP.
If the only thing that changes is the pressure from 1.00 atm to 2.00 atm, then we know the initial volume, initial pressure, and final pressure. We can use Boyle's law.
Boyle's law: (initial pressure)*(initial volume) = (final pressure)*(final volume)
fill in the knowns
(1.00 atm)*(22.4 liters) = (2.00 atm)(final volume)
divide both sides by 2.00 atm
11.2 liters = final volume
