Answer:

Approximately 241 kJ/mol reaction.

Explanation:

How many moles of the reaction took place?

The coefficient in front of both NaOH and HCl are both one. In other words, one mole of the reaction will require one mole of NaOH and one mole and HCl.

\rm0.025\; L \times 0.100\; mol\cdot L^{-1} = 0.0025\; mol of both NaOH and HCl are available. As a result, 0.0025 moles of the reaction would have taken place.

How much heat was produced?

Approximate volume of the solution:

\rm 25.0 + 25.0 = 50.0\; mL.

Approximate mass of the solution:

\rm 50.0\; mL\times 1\;g\cdot mL^{-1} = 50.0\; g.

Q = c\cdot m \cdot \Delta T = \rm 50.0\; g \times 4.812\; J \cdot g^{-1} \cdot K^{-1} \times (25.5 - 23.0)\; K = 601.5\; J

Enthalpy change per mole reaction:

\displaystyle \Delta H = \frac{Q}{n} = \rm \frac{601.5\; J}{0.025\; mol} \approx 241000\; J\cdot mol^{-1} = 241\; kJ \cdot mol^{-1}.

1. What is the potential energy of a 8 kg ball that is at a height of 20 m?
weqwewe [10]

Answer:

1. 1568 J

2. 0 J

3. 1176 J

Explanation:

PE = mgh

(PE = Potential Energy) = (m = mass)(g = gravitational force which is 9.8)(h = height)

1. (3)(9.8)(20) = 1568 J

2. PE = (3)(9.8)(0) = 0 J

3. (5)(9.8)(24) =  1176 J

Will mark as brainliest
expeople1 [14]

The answer is C

because plants use light energy from the sun to make their own food providing energy. The food created is a type of sugar.

This would make it definitely not A or D. The only answers left would be B and C but, technically the sunlight doesn't deliver the sugar straight to the plant so I'd go with C.

Hope that his helped!
