Answer:
Explanation:
You need to know one piece of information for these problems. That is as follows:
There are 6.02 x 10^23 atoms in a mole of atoms or 6.02 x 10^23 molecules in a mole of molecules (actually there are 6.02 x 10^23 in a mole of anything).
So in 3.161 x 10^21 molecules of CO2 there are 3.161 molecules x (1 mole CO2/6.02 x 10^23 molecules CO2)= ?? moles CO2. Then multiply that by 2 to find the moles of O in CO2.
The others are done th same way.
With an increase in temperature, the particles gain kinetic energy and move faster. (The ANSWER is increase the temperature.)
I know for a fact the answer would (not) be the last option. This would not be a way that electricity would be able to really flow.
Your correct answer would be of when the
"e<span>
lectrons flow from the negative end of a source towards the positive end."This would be because when the electrons would be free, they would have enough energy to then move from the negative side of the end, to the positive side.</span>

Answer:
The answer is red.
Explanation:
- Methyl orange is an organic dye that used as an indicator in acid-base titrations because its color is changed according to pH of the medium (acidic, neutral or basic).
- Methyl orange is red in acidic solutions, orange in neutral solutions, and yellow in basic solutions.
Since pH of the solution is 2, the solution is acidic, the color of the solution will be red.
