<u>Answer:</u>

<em>Indonesia Bank one of the largest consumers of electricity or energy in any form depends on fossil fuels for energy.</em>

<u>Explanation:</u>

Utilisation of solar energy for their day to day basis such that the energy need is met would mean less use of fossil fuels and lesser greenhouse gases.

And also damage to the environment and this is a very important step by Indonesia to do their bit towards environment by controlling pollution and being largest consumer turning green would mean a lot.

Determine the average volume of 0.20 mol/l NaOH needed to neutralize 25 ml of diluted

Viktor [21]

12.5 mL of NaOH solution

Explanation:

We have the following chemical reaction in which sodium hydroxide (NaOH) react with acetic acid (CH₃-COOH) to form sodium acetate (CH₃-COONa) and water (H₂O):

NaOH + CH₃-COOH → CH₃-COONa + H₂O

molar concentration = number of moles / volume

number of moles = molar concentration × volume

number of moles of CH₃-COOH = 0.2 × 12.5 = 2.5 mmoles

*typically a vinegar solution have a concentration of acetic acid of 12.5 mol/L.

Taking in account the chemical reaction, we devise the following reasoning:

if 1 mmole of NaOH reacts with 1 mmole of CH₃-COOH

then X = 2.5 mmoles of NaOH reacts with 2.5 mmoles of CH₃-COOH

volume = number of moles / molar concentration

volume of NaOH solution = 2.5 / 0.2 = 12.5 mL

In the diagram, what is happening to the ENERGY during Segment C? Phase Change Diagram_Water Question 16 options: The kinetic en

Leviafan [203]

There was an increase in kinetic energy during the segment C and in other segments

Recall: That temperature is a measure of the average kinetic energy, so increasing temperature all cause increasing kinetic energy and vice versa.

However too, the heat energy which is added during the phase change is usually used to overcome forces in order to hold the molecules together.

<h3>What is kinetic energy?</h3>

Kinetic energy is the type of energy an object or a body posesss due to it motion

The body usually maintains it's kinetic energy unless the speed changes

<h3>What it potential energy?</h3>

Potential energy is a type of energy an object or a body had due to its relative position.
