The balanced chemical reaction is given above however I believe the coefficients are wrong. It should be:
4K + O2 = 2K2O
We use data from that reaction to obtain relationships between substances. We are given the amount of potassium that reacts. We proceed as follows:
1.52 mol K ( 2 mol K2O / 4 mol K ) = 0.76 mol of K2O is formed
A diversity of scientists is important for reducing bias and for providing different ways of looking at the world. ... To the extent that we can remove our biases and learn from multiple perspectives, we will understand our world better.
Answer:
5.81L
Explanation:
N1 = 1.70 moles
V1 = 3.80L
V2 = ?
N2 = 2.60 moles
Mole - volume relationship,
N1 / V1 = N2 / V2
V2 = (N2 × V1) / N1
V2 = (2.60 × 3.80) / 1.70
V2 = 9.88 / 1.70
V2 = 5.81 L
The volume of the gas is 5.81L
