3 0

Answer:

88.38K gm/s^{2}

Explanation:

Mass and weight are quite different terms .

Weight is defined as the amount of force exerted on the earth due to our mass and gravity of acceleration.

w=m*g

Given that the mass is 90 kg and gravity of acceleration of earth is 9.82 m/s^2.

So weight will be

w=90*9.82\\w=88.38K gm/s^2

According to the following reaction, how much energy is evolved during the reaction of 32.5 g B2H6 with excess Cl2? The molar ma
bonufazy [111]

Answer:

1640 kJ are involved in the reaction

Explanation:

In the reaction:

B₂H₆(g) + 6Cl₂(g) → 2 BCl₃(g) + 6HCl(g)

<em>1 mol of B₂H₆(g) with 6 moles of Cl₂(g) produce 1396 kJ of energy.</em>

<em />

Now if 32.5g of B₂H₆(g) react with excess Cl₂(g), moles involved in reaction are:

32.5g B_2H_6\frac{1mol}{27.67g} = 1.175 moles

If 1 mol produce 1396kJ of energy, 1.175 moles produce:

1.175mol\frac{1396kJ}{1mol} = 1640kJ\\

Thus, <em>1640 kJ are involved in the reaction</em>
