r-ruslan [8.4K]4 years ago
7 0

Answer:

Because Aluminum by loosing electron to form ion it's nuclear effective charge increase hance more pull to it's corresponding valence she'll thus appear smaller

While

Chlorine due to gaining of electron to form ion it's effective nuclear charge decrease thus less pull to it's corresponding valence hence appear large relatively

Select the term that matches each definition:
Zinaida [17]

Answer:

a) common ion effect

b) solubility

c) saturated solution

d) solubility product constant

e) molar solubility

Explanation:

When a substance, say BA2 is dissolved in a solution and another substance CA2 is dissolved in the same solution. The solubility of BA2 is decreased due to the addition of CA2. This is known as common ion effect.

The mass of a substance that will dissolve in a given Volume of solvent is known as it's solubility.

The molar solubility is the amount of moles of solvent that dissolves in 1 dm^3 of solvent.

A solution that contains just as much solute as it can normally hold at a given temperature is known as a saturated solution.

Lastly, the product of molar solubilites raised to the power of the molar coefficient is know as the solubility product constant.

Trace amounts of sulfur (S) in coal are burned in the presence of diatomic oxygen (O2) to form sulfur dioxide (SO2). Determine t
Mashcka [7]

Answer:

0.99 kg O₂

1.9 kg SO₂

Explanation:

Let's consider the reaction between sulfur and oxygen to form sulfur dioxide.

S + O₂ → SO₂

The mass ratio of S to O₂ is 32.07:32.00. The mass of oxygen required to react with 1 kg of sulfur is:

1 kg S × (32.00 kg O₂/32.07 kg S) = 0.998 kg O₂

The mass ratio of S to SO₂ is 32.07:64.07. The mass of sulfur dioxide formed when 1 kg of sulfur is burned is:

1 kg S × (64.07 kg SO₂/32.07 kg S) = 1.99 kg SO₂

The balanced equation for the reaction between iron sulfied and water is best represented by?​
nika2105 [10]

FeS  +   H₂O    →    FeO   +    H₂S

Explanation:

  Iron Sulfide = FeS

  Water = H₂O

                FeS  +   H₂O    →    FeO   +    H₂S

To balance this equation, we can use a mathematical method. This involves solving simple algebraic equations

                 aFeS  +   bH₂O    →    cFeO   +    dH₂S

 a,b,c and d are the coefficients needed to balance up the equation:

      Conserving Fe: a = c

                           S:  a = d

                           H:  2b = 2d

                           O:  b = c

let a = 1, c= 1, b = 1 d = 1

     The balanced equation is:  FeS  +   H₂O    →    FeO   +    H₂S

Imagine that you have an ideal gas in a 6.70 L container, and that 1450 molecules of this gas collide with a square-inch area of
kakasveta [241]

Answer:

they could collide 241.66 molec / in² by increasing the volume to 40.2L

Explanation:

ideal gas:

<u>Boyle Law</u>: at constant temperature the pressure of a gas varies inversely with the volume

  • V1 * P1 = V2 * P2
  • P = F / A

∴ V1 = 6.70 L;

∴ P1 = 1450 molec / in²

∴ V2 = 40.2 L

⇒ P2 = (( 6.70 L ) * ( 1450 molec/in²)) / 40.2 L

⇒ P2 = 241.66 molec/in²
