Ireally need
1. 2al + 3h2so4 -> al2(so4)3 + 3h2 in the balanced equation above, what is the ratio of the reactant aluminum to the product aluminum sulfate?

2. what coefficients would be needed to balance the following chemical equation? put them in order separated by commas. if no coefficient is needed, put a 1. example: 1,2,3,4 c2h4(g) + o2(g) > co2(g) + h2o(g) a. 1,2,3,3 b. 2,1,1,2 c. 1,3,2,3 d. 1,3,2,2

3. 25 grams of mg react with 20 grams of hcl. identify the limiting reagent. how much of the excess reagent remains (in grams)
mg(s) + 2hci(aq) > mgci2(aq) + h2(g)

1. The ratio of the reactant aluminum to the product aluminum sulphate is 2:1

2. Option D. 1,3,2,2

Explanation: 1. From the balanced equation:

2Al + 3H2SO4 -> Al2(SO4)3 + 3H2

2moles of Al produced 1mole of Al2(SO4)3. Therefore, the ratio will be 2:1

2. C2H4 + 3O2 ---> 2CO2 + 2H2O from the equation, the coefficients are 1,3,2,2

the answer is b & c i believe : )

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
