(a)What mass of oxygen is compulsory to conflict utterly with 24g of CH4 in a following reaction?
CH4(g) + 2O2(g) ——> CO2(g)+2H20(l)
(b)How most mass of CH4 would conflict with 96g of oxygen?

Hydrocarbons have been organic devalue stoical of hydrogen as well as carbon.A 0.1647g representation of a pristine hydrocarbon upon blazing in a explosion blood vessel constructed 0.5694g of CO2
and 0.0845g of H2O.Determine a % of these elements in a hydrocarbon.

On explosion 2.4g of a devalue of carbon,hydrogen as well as oxygen gave 3.52g of CO2 as well as 1.44g of H2O.The molecular mass of a devalue was found to be 60amu.
(a)What have been a rank as well as file of carbon,hydrogen as well as oxygen in 2.4g of a compound?
(b)What have been a experimental as well as molecular formulae of a compound?

In a greeting H2+Cl2——->2HCl,how most grams of Cl2 have been indispensable to conflict utterly with 0.245g of H2 to give HCl?How most HCl is formed?

3.65g of H2 as well as 26.7g of O2 have been churned as well as reacted.How most grams of H2O have been formed?

Caustic soft drink NaOH can be commercially rebuilt by a greeting of Na2CO3 with slaked lime,Ca(OH)2.How most grams of NaOH can be performed by treating 2kg of
Na2CO3 with Ca(OH)2?

A portable hydrogen generator utilizes a greeting
CaH2+H2O——–>Ca(OH)2+2H2
How most grams of H2 can be constructed by 100g cartridge of CaH2?

The greeting 2Al+3MnO——–>Al2O3+3Mn deduction compartment a tying piece is consumed.A reduction of 220g Al as well as 400g MnO was exhilarated to beginner a greeting .Which
initial piece remained in additional as well as by how much? (Al=27,Mn=55)

KClO4 might be rebuilt by equates to of following array of reactions
Cl2+2KOH———>KCl+KClO+H2O
3KClO———>2KCl+KClO3
4KClO3——->3KClO4+KCl
How most Cl2 is indispensable to hope for 400g KClO4 by a on top of sequence? (K=39,Cl=35.5,O=16,H=1)

2g of a reduction of Na2CO3 as well as NaHCO3 was exhilarated when a weight marked down to 1.876g .Determine a % combination of a mixture.

Calculate a weight of 60% H2SO4 compulsory to spoil 150g of marker (calcium carbonate) (Ca=40,C=12,O=16,S=32).
