What would cause the shape of a molecule to be tetrahedral?
Phantasy [73]

Answer:

A molecule is tetrahedral if the central atom has four bonds and no lone pairs.

Explanation:

A typical example is a molecule of methane (see image).

The electron pairs in the bonds repel the electrons in the other bonds, so they all try to get as far from each other as possible.

They can do this if the bonds point to the corners of a tetrahedron, with bond angles of 109.5°.

A chemical reaction produces 653 550 kj of energy as heat in 142.3min. calculate the rate of energy transferred in kj per minute
miskamm [114]

We have the value of  

Total energy produced in the chemical reaction=653 550 KJ  

Time needed=142.3min  

To calculate the rate of energy transfer, that is the amount of energy produced per minute.  

Rate of energy transfer=\frac{Total energy produced}{Time needed}

=\frac{653 550}{142.3}

=4592.76 KJ min⁻¹

So, the rate of energy transfer is 4592.76 KJ min⁻¹.

How many grams of benzene (C6H6) will produce 42 grams of CO2?
3241004551 [841]
The balanced chemical reaction is:<span>

</span><span>2C6H6 + 15O2 → 12CO2 + 6H2O</span><span>

We are given the amount of carbon dioxide to be produced for the reaction. This will be the starting point of our calculations.

</span>42 g CO2 ( 1 mol CO2 / 44.01 g CO2) ( 2 mol C6H6 / 12 mol CO2 ) (78.1074 g C6H6 / 1 mol C6H6) = 12.42 grams of C6H6
