To complete the balancing of the following combustion reaction, we must do elemental balances. For C, there is 5 on the left side hence there should be 5 CO2. For H, H20 should be 9/2. Next we balance O. on theright side we find a total of 29/2. So the o2 on the left side should be 29/4. To have whole number stoich.coeff. we multiply the numbers by 4, hence answer is
4C5H9O + 9O2= 20 O2 + 18 H20.
Answer: Niagra Falls Happens
Explanation:
Hey there!
27 tells us the sum of protons and neutrons is 27.
Al tells us we have 13 protons.
3- tells us that there are 3 more electrons than protons.
13 + n = 27
neutrons = 14
13 + 3 = 16 electrons
27Al3- has 13 protons, 14 neutrons, and 16 electrons.
Hope this helps!
