Answer:
5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.
Explanation:
Moles of copper(I) sufide = 2.9 mol
According to reaction, 1 mole of copper(I) sulfide is obtained from 2 moles of copper, then 2.9 moles of copper(I) sulfide will be obtained from :
copper
5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.
The conclusion includes a summary of the results, whether or not the hypothesis was supported, the significance of the study, and future research.
Most of the mass of an atom is in the Nucleus.
Answer:
Since the equation for amount remaining is (1/2)^n, where n stand for the number of half lives, after 2.3 half lives the equation is (1/2)^2.3. This makes the answer about 1/4.92, which converts to about 20% of the original amount.
