Explanation:

1)

NH_{4}^++OH^-\rightarrow NH_4OH

3NH_{4}^++ClO_3^{3-}\rightarrow (NH_4)_3ClO_{3}

2NH_{4}^++SO_3^{2-}\rightarrow (NH_4)_2SO_{3}

2NH_{4}^++HPO_{4}^{2-}\rightarrow (NH_4)_2HPO_{4}

2)

Al^{3+}+3OH^-\rightarrow Al(OH)_3

Al^{3+}+ClO_3^{3-}\rightarrow AlClO_3

2Al^{3+}+3SO_3^{2-}\rightarrow (Al)_2(SO_{3})_3

2Al^{3+}+3HPO_{4}^{2-}\rightarrow (Al)_2(HPO_{4})_3

3)

Pb^{4+}+4OH^-\rightarrow Pb(OH)_4

3Pb^{4+}+4ClO_3^{3-}\rightarrow Pb_3(ClO_3)_4

Pb^{4+}+2SO_3^{2-}\rightarrow Pb(SO_{3})_2

Pb^{4+}+2HPO_{4}^{2-}\rightarrow Pb(HPO_{4})_2

what happens to the radius of the atoms of an element as you go towards the right in a row of the periodic table ?
Olegator [25]

Answer:

It decreases

Explanation:

As one moves from left to right on the periodic table, the radius of atoms reduces due to the nuclear pull.

  • The size of an atom estimated by the atomic radius is taken as half of the internuclear distance between the two covalently bonded atoms of non-metallic elements.
  • Across a period, atomic radius decreases progressively from left to right.
  • This is due to the increasing nuclear charge without attendant increase in the number of electronic shell.

A student mixed some yellow sulfur powder with some iron filings. She was able to take the iron out of the sulfur by using a mag
Kay [80]

Answer: Chemical change

Explanation:

Physical change is a change in which there is no rearrangement of atoms and thus no new substance is formed. There is only change in physical state of the substance. The change can be reversed using physical methods.

Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state. The change can only be reversed using chemical methods.

Thus when iron and sulfur are heated in a test tube, the chemical change occurs and thus lead to formation of new substances which could not be separated using magnet.

For the following reaction, calculate how many moles of NO2 forms when 0.356 moles of the reactant completely reacts.
Nesterboy [21]

Answer:

0.712 mol of NO₂ are formed .

Explanation:

For the reaction , given in the question ,

2 N₂O₅ ( g )  →  4 NO₂ ( g ) + O₂ ( g )

From the above balanced reaction ,

2 mol of N₂O₅  reacts to give 4 mol of NO₂

Applying unitary method ,

1 mol of N₂O₅  reacts to give 4 / 2 mol of NO₂

From the question , 0.356 mol of N₂O₅ are reacted ,

<u>now, using the above equation , to calculate the moles of the NO₂ , as follow -</u>

Since ,

1 mol of N₂O₅  reacts to give 4 / 2 mol of NO₂

0.356 mol of N₂O₅  reacts to give 4 / 2 * 0.356 mol of NO₂

Calculating ,

0.712 mol of NO₂ are formed .
