Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)

Products: Carbon dioxide (CO₂) and Water (H₂O)

Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.

Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O

Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O

The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.

Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.

A 155g sample of an unknown substance was; heated from 25.0°c to 40°c. In the process, the substance absorbed 2085 J of energy.
Archy [21]

Answer:

0.897 J/g°C

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Mass (M) of substance = 155g

Initial temperature (T1) = 25.0°C

Final temperature (T2) = 40°C

Change is temperature (ΔT) = T2 – T1 = 40°C – 25.0°C = 15°C

Heat Absorbed (Q) = 2085 J

Specific heat capacity (C) of the substance =?

Step 2:

Determination of the specify heat capacity of the substance.

Applying the equation: Q = MCΔT, the specific heat capacity of the substance can be obtained as follow:

Q = MCΔT

C = Q/MΔT

C = 2085 / (155 x 15)

C = 0.897 J/g°C

Therefore, the specific heat capacity of the substance is 0.897 J/g°C

Select True or False: The equilibrium constant for the chemical equation 2NO(g) O2(g) 2NO2(g) is two times the equilibrium const
ser-zykov [4K]

Answer:

False

Explanation:

The first reaction is;

NO(g) + 1/2O2(g) ---->NO2(g)

K= [NO2]/[NO] [ O2]^1/2

The second reaction is;

2NO(g) + O2(g) ---->2NO2(g)

K'= [NO2]^2/[NO]^2 [O2]

It now follows that;

K'= K^2

Hence the statement in the question is false
