A reaction begins with 130.5g of substance X and substance Y. How many grams of
Paha777 [63]

Answer:

130.5g

Explanation:

At the of the reaction, the combined mass of X and Y will be 130.5g.

The premise for this conclusion is based on the law of conservation of matter.

This law states that "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

In essence, in a chemical reaction, there is no mass loss.

  • The amount of product in the reaction is expected to be the same as the amount of reactants used in the experiment.
  • When we start with 130.5g then we should end with 130.5g

How does gravity affect the inner planets? (site 2)<br><br>                 <br><br>​
ikadub [295]

The presence of an atmosphere, temperature, and distance from the Sun do not affect a planet's gravity. Are the objects in the solar system still or are they in motion? The Sun's gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them.

What alkene(s) would be produced from the dehydration of cyclopentanol? (enter "none" in the unused blanks.)
amm1812
Dehydration of Alcohols yield Alkenes. Depending upon the starting material (alcohols) different alkenes are being formed either by following saytzeff rule or Hoffman rule. In case of Cyclopentanol only one alkene is produced (i.e. Cyclopentene) as shown below.

Carbon monoxide replaces oxygen in oxygenated hemoglobin according to the reaction: HbO2(aq) + CO(aq) ∆ HbCO(aq) + O2(aq) a. Use
gayaneshka [121]

The question is incomplete, complete question is;

Carbon monoxide replaces oxygen in oxygenated hemoglobin according to the reaction:

HbO_2(aq) + CO(aq)\rightleftharpoons HbCO(aq) + O_2(aq)

Use the reactions and associated equilibrium constants at body temperature to find the equilibrium constant for the above reaction.

Hb(aq) + O_2(aq)\rightleftharpoons HbO_2(aq) ,K_1=1.8

Hb(aq) + CO(aq)\rightleftharpoons HbCO(aq) ,K_2=306

Answer:

The equilibrium constant for the given reaction is 170.

Explanation:

Hb(aq) + O_2(aq)\rightleftharpoons HbO_2(aq) ,K_1=1.8

K_1=\frac{[HbO_2]}{[Hb][O_2]}

[Hb]=\frac{[HbO_2]}{[K_1][O_2]}..[1]

Hb(aq) + CO(aq)\rightleftharpoons HbCO(aq) ,K_2=306

K_2=\frac{[HbCO]}{[Hb][CO]}..[2]

HbO_2(aq) + CO(aq)\rightleftharpoons HbCO(aq) + O_2(aq)

K_c=\frac{[HbCO][O_2]}{[HbO_2][CO]}..[3]

Using [1] in [2]:

K_2=\frac{[HbCO]}{\frac{[HbO_2]}{[K_1][O_2]}\times [CO]}

K_2=K_1\times \frac{[HbCO][O_2]}{[HbO_2][CO]}

K_2=K_1\times K_c ( using [3])

306=1.8\times K_c

K_c=\frac{306}{1.8}=170

The equilibrium constant for the given reaction is 170.
