Ethane is formed from the reaction carbon and hydrogen:
2C(s) + 3 H2(g) C2H6(g)
If 7.08 g of carbon and 4.92 g of hydrogen are allowed to react, how much of the excess reactant (the “non-limiting reactant”) is left over?
a. 1.78 g
b. 2.16 g
c. 2.78 g
d. 3.14 g
e. 4.92 g

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
