CO, + H2O –H^2 CO^3 The reaction is which type of chemical reaction?

Rudik [331]

Answer:

Combination or synthesis reaction

Explanation:

The reaction is a combination or synthesis reaction.

Let us write the reaction equation:

CO + H₂O → H₂CO₃

A combination or synthesis reaction is one in which a single product forms from two or more reactants. The formation of a compounds from the union of their constituent elements falls into this category of reaction.

The combination of carbon monoxide and water to give hydrogen carbonate is one of such reaction.

Use the chemical equation and the bond diagram to answer the question.

Scilla [17]

Answer:

O=O bond

Explanation:-

Note it down that the bond having highest Hydrogen enthalpy has strongest bond.

Now

O=O(495KJ/mol)
O-O(146KJ/mol)
O-H(467KJ/mol)
H-H(432KJ/mol)

Hence

$\\ \bull\sf\dashrightarrow O=O>O-H>H-H>O-O$

At sea level water usually boils at 100. °C and 760. mmHg pressure. On Mt Whitney, the pressure is about 560. mmHg. At what temp

WITCHER [35]

Answer:

91.7°C

Explanation:

We suppose you have a formula to work from. However, that is not supplied with this problem statement, so we looked one up.

The formula in the attachment is supposed to have good accuracy in the temperature range of interest. It gives vapor pressure of water in kPa, not mmHg, so we needed the conversion for that, too.

560 mmHg corresponds to about 74.66 kPa. The attached "Buck equation" formula is used to find the corresponding temperature. The exponential equation could be solved algebraically using logarithms and the quadratic formula, but we choose to find the solution graphically.

Water boils at about 91.7 °C on Mt. Whitney.
