Answer:
The reaction takes place is
2 (C2H6) + 7 (O2) → 4(CO2) + 6(H2O)
According to the equation,
60g ethane requires 7x32= 224g oxygen
here ethane is in excess.oxygen will be consumed completely.
hence
2.9 g O2 will consume 60×2.9/224=0.776g of C2H6
now,
2 moles of C2H6 produces 4 moles of CO2!
60g ethane produces 4x44 g CO2
hence amount of CO2 produced =4×44×0.776/60=2.27g
Answer:
a) gold - Solid
b) gasoline - liquid
c) oxygen - gaseous
d) olive oil - liquid
e) mercury (found in thermometers) - liquid
f) aluminum - solid
Explanation:
Matter exists in three states viz: solid, gas and liquid. Note that, room temperature is a neither hot or cold temperature, which is about 20-23°C.
A) Gold is a transition metal with the symbol Au. At a room temperature, Gold, like most metals are found as SOLIDS.
B) Gasoline is a liquid mixture of refined hydrocarbons majorly used as fuels.
C) Oxygen is a chemical element with symbol O. It is a constituent of natural air, which is a mixture of different gases including oxygen. Hence, at room temperature, Oxygen is a gas.
D) Olive oil is a vegetable oil got from olives. It is composed of fats and it's a liquid at room temperature.
E) Mercury is an element with symbol Hg. It is the only metallic element found naturally (at room temperature) as a liquid. It is used in thermometers.
F) Aluminum is another chemical element with symbol Al. It is a lustrous metal that occurs as a Solid in room temperature.

It could be 67.628 ounces but i dont fully know the question
Reaction rate tells us how fast or how slow a reaction proceeds. There are certain reactions that are reversible. This means that the reactant can form products and the products can form back the reactants. The reaction will proceed until it reaches equilibrium. Equilibrium is achieved when the rate of the forward reaction is equal to the rate of the reverse reaction. In equation form:
Sample reaction
R1 + R2 <--> P1 + P2
rate(forward) = rate(reverse)
kf [R1][R2]=kr [P1][P2]
K = kf/kr = [P1][P2]/[R1][R2]
K is the equilibrium constant
kf is the rate constant of the forward reaction
kr is the rate constant for the reverse reaction
[R1], [R2], [P1], [P2] = concentration of reactants (R) and products (R) (examples)
