A4 kg object is being pulled to the east by a 6 N force. What is the object's<br> acceleration?

Dahasolnce [82]

1.5 ms⁻²

Explanation:

We understand that Force is also given as mass * acceleration;

F = Ma

If force is 6N and the mass is 4kg of the object, the a can be evaluated as follows;

6 = 4a

6/4 = a

1.5 = a

= 1.5m/s²

In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions

padilas [110]

Answer:

$\triangle G= -6.7 KJ/mol$

Explanation:

From the question we are told that:

Chemical Reactions:

X=A⇌B,ΔG= 14.8 kJ/mol

Y=B⇌C,ΔG= -29.7 kJ/mol

Z=C⇌D,ΔG= 8.10 kJ/mol

Since

Hess Law

The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the number of steps taken.

Therefore

Generally the equation for the Reaction is mathematically given by

$T = +1 * X +1 * Y +1 *Z$

Therefore the free energy, ΔG is

$\triangle G=1 * \triangle G*X +1 * \triangle G*Y +1 * \triangle G *Z$

$\triangle G= +1 * (14.9) +1 * (-29.7) +1 * (8.10)$

$\triangle G= -6.7 KJ/mol$
