2.3/6.7 = 4.6/x

using cross products

2.3*x = 6.7 * 4.6

divide by 2.3

x = 6.7 * 4.6 / 2.3

x = 6.7 * 2

x = 13.4

Choice A

Which statement is correct?The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic.
mafiozo [28]

Answer:

The correct statements are :

1. The enthalpy of the reaction is -184.6 kJ, and the reaction is exothermic.

2. The enthalpy of the reaction is 184.6 kJ and the reaction is endothermic.

Step-by-step explanation:

Enthalpy of reaction is amount of heat absorbed or released during the reaction.

If energy is required, enthalpy of reaction is positive and if energy is released the enthalpy of reaction is negative.

Exothermic reaction: The chemical change is accompanied by the release of heat energy

Endothermic reaction: The chemical change is accompanied by the absorption of heat energy.

So, from the above definitions, it is clear that the enthalpy of reaction of a exothermic reaction is negative and that of a endothermic reaction is positive.

What is the minimum force required to prevent a ball weighing 22.6 lb from rolling down a ramp which is inclined at 39.0 degrees
Alona [7]
The correct answer is 14.2 lb which is choice D.

Let:

F = minimum force required to prevent ball from rolling down the ramp

The formula will be:

F = w * sin theta

F = w * sin (39 degrees)

F = 22.6 * sin (39) 
= 14.2 lb (this is rounded to the nearest tenth)

11. Explain how to evaluate the expression 9 +(45 x 2) = 10.
Dmitry_Shevchenko [17]

The Answer Is 18

Order Of Operation laws says that you must do the parentheses first, 45x2.

45x2=90

The next thing you must do is divide 90 by 10 since division is before addition.

90/10=9

Now combine like terms.

9+9=18
