Answer:
This is a stoichometric ratio
Explanation:The equation is already balanced, so all you have to do is.
1. Count the molar mass of Ammonia N nitrogen atom has an atomic mass of 14 so add 14+ 3 hydrogens which each have a mass of 1 that gives you 17 grams per mole of ammonia on the right side, so they want to know how much hydrogen is needed to make 100 grams of ammonia, so what you have to do is divide 100/17=2.94 that is your ratio so you now know there is 2.94 times everything in the equation so at first you had 3 moles of hydrogen now you have 3*2.94 moles of hydrogen. You also have 2.94 moles of N2 gas. It's just a ratio if you plug in 200 instead you have to multiply everything by 200/17=11.76 ratio.
1st step count molar mass of product.
2nd plug number they gave you and divide it by molar mass ratio then multiply everything in equation by that ratio.
B, not every place has the same evaporation rate, but it does redistribute water and areas have different climates.
Answer:
The pulling atom is oxidized while the pulled atom is reduced. Grade 9 Chemistry
Explanation:
Just use the equation M=DV which means Mass equals Density times Volume. Simply plug your values into the equation to get
M=.789(139) and solve
