Answer:
For a particular chemical reaction, the enthalpy of the reactants is -400 kJ. The enthalpy of the products is -390 kJ. The entropy of the reactants is 0.2 kJ/K. The entropy of the products is 0.3 kJ/K. The temperature of the reaction is 25oC. What can you conclude about this reaction?
It is exergonic
It is endergonic
it is a redox reaction
It is being catalyzed by an enzyme
Answer: the correct answer is C velocity.
Explanation: I just got the answer wrong on the exam.
Answer:I think it’s mechanical energy
Explanation:
Answer:

Explanation:
Force is equal to mass times acceleration.

By dividing both sides by m, we rearrange the formula for a (acceleration).

The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.
- A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².
The mass is 2300 grams, but we need to convert it to kilograms.
- To convert grams to kilograms, divide by 1,000
- 2300 g/1000= 2.3 kg

Substitute the values into the formula.

Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).


Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7

The acceleration is about <u>2.7 meters per second squared.</u>
