The question is incomplete, the elements to be arranged as required are shown in the image attached to this answer.

Answer:

K<Mg<P<O

Explanation:

Electronegativity is the ability of an atom of an element in a compound to attract the shared electrons of a bond towards itself. Atoms of highly electronegative elements tend to polarize a covalent bond leading to polar covalent bonds and dipole moments. Electronegativity increases across the period but decreases down the group hence the arrangement of elements in the answer provided above.

Fe2O3 + _H2SO4 → _Fe2(SO4)3 + __H2O what are the coefficients
lbvjy [14]

Answer:

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

Explanation:

Step 1: Write out unbalanced reaction

Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Step 2: Balance

We need the same number of SO₄²⁻ on each side

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Now we need the same amount of H⁺ on each side

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

Select the pH value you would expect for each of these solutions. an aqueous solution of HNO3 an aqueous solution of NaCl an aqu
Neko [114]

Answer:

An aqueous solution of HNO_3 will be an acid and have a pH of less than 7.

An aqueous solution of NaCl will be a neutral solution and have a pH equal to 7.

An aqueous solution of NaOH will be an base and have a pH of more than 7.

Explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,  

pH = - log [H⁺]

pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.

Thus,

<u>An aqueous solution of HNO_3 will be an acid and have a pH of less than 7.</u>

<u>An aqueous solution of NaCl will be a neutral solution and have a pH equal to 7.</u>

<u>An aqueous solution of NaOH will be an base and have a pH of more than 7.</u>

A mixture of oxygen, hydrogen, and nitrogen exerts a total pressure of 378 kPa. If the partial pressures of oxygen and hydrogen
sertanlavr [38]
What's the relationship between total and partial pressure? The total pressure is the sum of the parcial pressures!


So for us, it would be:

378= 212+101+x

where x is the parcial pressure of nitrogen.

Now we count:
378= 212+101+x
378=313+x
378-313=x
65=x

So the parcial pressure exerted by nitrogen is 65!
