Answer:

2.5 moles HCl = 2.5moles x 36g/mole HCl = 90 grams HCl.

Explanation:

From equation ratios the reaction ratio is 1 mole Mg to 2 moles HCl. That is, given 1.25 moles Mg, moles HCl consumed will be 2(1.25)moles, or 2.5 moles HCl = 2.5moles x 36g/mole HCl = 90 grams HCl.

How much heat is released when 27.6 g P C l subscript 3 cools from 83.1 °C to 55.6 °C? (The specific heat of P C l subscript 3 i
Paul [167]

Answer: Thus 663 J of heat  is released when 27.6 g PCl_3 cools from 83.1 °C to 55.6 °C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat released = ?

m = mass of substance = 27.6 g

C = specific heat capacity = 0.874J/g^0C

Initial temperature= T_i = 83.1^0C

Final temperature  = T_f  = 55.6^0c

Change in temperature ,\Delta T=T_f-T_i=(55.6-83.1)^0C=-27.5^0C

Putting in the values, we get:

Q=27.6g\times 0.874J/g^0C\times -27.5^0C=-663J

As the value of q is negative, it means the heat has been released and it is 663J

Which of the following matches is not correct?
Furkat [3]

Answer:

SO42 - Trigonal planar ion

Explanation:

The SO4^2- ion is tetrahedral and not trigonal planar because the sulphur atom has four regions of electron density which includes the lone pair of electrons on sulphur atom.

This accounts for the observed tetrahedral arrangement of electron pairs around the central sulphur atom in SO4^2- ion, hence the answer.
