2 answers:
Answer:
it is a combustion reaction.
Explanation:
Combustion reaction is the type of reaction in which a hydrocarbon heated up in the presence of oxygen to form water and carbon dioxide.
is ethane and it is a hydrocarbon. The combustion reaction of ethane is as follows :
So, the correct option is (c).
Answer:
2C2H6 + 7O2 → 4CO2 + 6H2O
Explanation:
Combustion is when a hydrocarbon (a compound made of only hydrogen and carbon) reacts with oxygen at high temperature to produce CO2 and H2O gases.

Answer:
H = 5.35 cm
Explanation:
As per energy conservation we know that energy stored in the spring is converted into gravitational potential energy when it is reached at the top
now we have
here we know that
m = 1 kg
k = 105 N/m
x = 0.1 m
now plug in all data in it
now solving for height H we have
Answer:
The work done by you on the two cart system is 2 N-m
Explanation:
Work done is the product of force and displacement.
W = F * D
Substituting the given values we get -
W =
The work done by you on the two cart system is 2 N-m
Answer:
D. none of them.
Explanation:
This is because Ohm's law is:
Voltage = Current × Resistance
or,
V = IR
