Answer:
1.98 g
Explanation:
The balanced reaction would be:
2CO + O2 = 2CO2
We assume that the gases are ideal gas so that we use the relation that 1 mol of an ideal gas is equal to 22.4 L of the gas at STP. From that relation, we get the number of moles and we can convert it to other units. We do as follows:
1.0 L CO ( 1 mol / 22.4 L ) ( 2 mol CO2 / 2mol CO ) = 0.045 mol CO2 produced
0.045 mol CO2 ( 22.4 L / 1 mol ) = 1 L of CO2
0.045 mol CO2 ( 44.01 g / 1 mol ) = 1.98 g of CO2
I'm not 100% sure but I think it's false
Answer:
15.5 km
Explanation:
1.55x10^4m
1.55x10000m
15500m
1km=1000m
b=15500m
1km*15500m=b*1000m
1km*15500m/1000m=b*1000m/1000m
b=15.5km
Hope this helps ;) ❤❤❤
I would go with false but idk
You are given the number of grams of Chromium which is
156 grams. The molar mass of chromium is 52 grams per mole. Divide 156 grams to
52 grams per mole of Chromium and you will get 3 moles of Chromium. The answer is letter B.
