Students are completing a table about a particular subatomic particle that helps make up an atom. The students have filled in one cell of the table so far. A 3-column table with 2 rows. The first row has entries Mass (a m u), location, charge. The second row has entries 1, nothing, nothing.

Based on the information shown, which statement about the subatomic particle must be correct?
Its location is in the nucleus, because the particle is a proton or a neutron.
Its location is in the nucleus, because the particle is a neutron or an electron.
Its charge is +1, because the particle is a proton.
Its charge is 0, because the particle is a neutron.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2

50.23 i believe is correct but don't quote me on that.
