Answer is: <span>the molecular mass ratio of two gases is 1 : 256.
</span>rate of effusion of
gas1 : rate of effusion of gas = 16 : 1.<span>
rate of effusion of gas1 = 1/√M(gas1).
rate of effusion of gas2 = 1/√M(gas2).
rate of effusion of gas1 = rate of
effusion of gas2 </span>· 16<span>.
</span>1/√M(gas1) = 1/√M(gas2) · 16 /².
<span>1/M(gas1) = 1/M(gas2) </span>· 256.
<span>M(gas1) </span>· 256 = M(gas2).<span>
</span>
Answer:renewable
Explanation:Renewables Can Cost Less than Fossil Fuels
These days, the energy produced by renewables is just as affordable as energy produced by fossil fuels, if not cheaper in some cases. Some solar panel projects can even generate power at roughly half the cost of fossil fuels like coal. That's a lot of potential savings.
Answer:
Ag2S
Explanation:
10.8 gm of silver, 12.4 gm of silver sulfide, so 12.4 -10.8 = 1,6 gm of sulfur
silver atomic weight is 108, sulfur atomic weight is 32 so
10.8/108; = 0.10 mole Ag 1.6/32 = 0.05 mole sulfur
so there is a 2:1 ratio of silver to sulfur, so the compound is 2 silver 1 sulfur or Ag2S
Na is reduce as it gain electron from cl
