What needs to happen for the equation CH4 + O2 → CO2 + H2O to be balanced?

ludmilkaskok [199]

The answer is B.
in the original equation, CH4 + O2 → CO2 + H2O, there are:

REACTANTS: 2 carbon, 4 hydrogen, 2 oxygen
PRODUCTS: 2 carbon, 2 hydrogen and 1 oxygen.

If we change the equation to this,
CH4 + 2O2 → CO2 + 2H2O, then there are now:

REACTANTS: 2 carbon, 4 hydrogen, 4 oxygen
PRODUCTS: 2 carbon, 4 hydrogen, 4 oxygen
and thus the equation is balanced

How much of an alloy that is 30% copper should be mixed with 50 ounces of an alloy that is 60% copper in order to get an alloy t

kompoz [17]

Answer: 180 i think

Step-by-step explanation: .5*200+.2X=.3(200+X)

100+.2X=60+.3X

.2X-.3X=60-100

-.1X=-40

X=-40/-.1

X=400 OUNCES OF 20% COPPER.

PROOF

.5*200+.2*400=.3(200+400)

100+80=.3*600

100+80=180

180=180
