Answer: SnO2 + 2 H2 = Sn + 2 H2O
Explanation: I used a balance equation website. It's called WebQC if you want to check it out for future help.
The correct answer would be 0.254.
Imagine you are in a swimming pool 30m deep. Assuming you know that water is denser than air, you would know that the 30m of water above you will carry more weight, and press down on your body. Say you were in a swimming pool 60m deep, you would be sandwiched between 30m of water pressing down on you, and the upthrust created by the 30m of water below you.
In a building 30m up, the pressure will be regulated, as you are in a building. The floor will be strong enough to support the weight of the body, and the body will not recoil into itself.
Answer:
696g
Explanation:
To determine the mass of ethylbutanoate produced, it is important that we know the number of moles of ethylbutanoate produced.
Now from the chemical equation, it can be seen that one mole of ethanol produces one mole of ethylbutanoate. This means that 6.0 mol of ethanol will surely produce 6.0 mol of ethylbutanoate.
Now, we need to get the mass of ethylbutanoate produced. The mass of ethylbutanoate produced is the number of moles of ethylbutanoate produced multiplied by the molar mass of ethylbutanoate produced.
The molar mass of ethylbutanoate is 12(6) + 12(1) + 16(2) = 116g/mol
The mass thus produced is 116 * 6 = 696g
