8 0

Answer:

The efficiency of the machine is 40 %.

Explanation:

We have,

Output work by the machine is 4 joules and the input work is 10 joules.

It is required to find the efficiency of a machine. The efficiency of a machine is given by the ratio of output work to the input work. It is given as :

\eta=\dfrac{4}{10}\times 100\\\\\eta=40\%

So, the efficiency of the machine is 40 %.

In this reaction diagram which part represents the doffrence in energy between the reactants and the products?
Annette [7]

Answer:

The correct answer is - option C. G.

Explanation:

In this reaction diagram, there is a representation of the reaction profile. The reaction profile shows the change that takes place during a reaction in the energy of reactants or substrate and products. In this profile, activation energy looks like a hump in the line, and the minimum energy required to initiate the reaction.

The overall energy of the reaction, including or excluding activation energy depends on the nature of the reaction if it is exothermic or endothermic. and products are represented by the G which shows the difference between the energy of the reactants and products.
