Which of the following will have same number of molecules at STP. a)280cm3 of CO2 and 280cm3 of N2O. B)44g of CO2 and 11.2dm3 CO c)11.2dm3 of O2 and 32g of O2 d)28g of N2 and 5.6dm3 of oxygen PLEASE EXPLAIN IN DETAIL :))

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

H2so4(aq) + mg(s)—> mgso4(aq) +h2(g) which substance is the acid in the reaction?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
