Answer:
True
Explanation:
Yes I agree object can be in motion and in not motion at the same time for example there are two men travelling on the bus one person is A another person is B. the person be B rest so by seeing person be the person A also sits but the person see who saw the person be B move along with person C so the the person be B is in rest for person Abut is motion for a person C.
2 moles of Na3PO4 form from 6.0 mol NaOH. Details about stoichiometry can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated stoichiometrically as follows:
3NaOH + H3PO4 → 3H₂O + Na3PO4
According to this equation,
3 moles of NaOH produces 1 mole of Na3PO4
This means that 6 moles of NaOH will produce 6/3 = 2 moles of Na3PO4
Therefore, 2 moles of Na3PO4 form from 6.0 mol NaOH.

<h3>
Answer:</h3>
Reactivity increases because the valence level is further from the nucleus of an atom.
<h3>
Explanation:</h3>
- The reactivity of elements in the periodic table depends on the position of the element in the periodic table.
- The trend in the reactivity across the period and down the group depends on whether one is dealing with metallic elements or non-metallic elements.
- Reactivity of metals such as alkali metals and alkali-earth metals increases down the group as the number of energy levels increases making valence electrons to be further from the nucleus.
- Reactivity of non-metallic groups such as halogen decreases down the group as energy levels increase which reduces the nuclear attraction of the valence electrons to the nucleus.
