methane gas reacts with chlorine gas to form dichloromethane and hydrogen chloride, as represented by the equation below.
__ch4(g) + __cl2(g) > __ch2cl2(g) + __hcl(g)
a) balance the equation
b0what is the mass of dichloroethane that can be produced when a 25.0 g sample of methane gas is placed in a reaction vessel containing 182.92 g of cl2(g)?

CH4+ 2Cl2→CH2Cl2+ 2HCl

Explanation:

mass is 132.8`125

as methane and dichlormethane has the same molar ration 1 to 1

mol of ch4 is 1.5625

so 1.5625 times mr of ch2cl2 is 132.8125

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
