3 0
Chemical reaction of PO₄³⁻ ion in water:
PO₄³⁻(aq) + H₂O(l) → HPO₄²⁻(aq) +OH⁻(aq).
Kb = [HPO₄²⁻] · [OH⁻] / [PO₄³⁻]; <span>base ionization constant.
</span>Base ionization constant <span>is the equilibrium </span>constant<span> for the </span>ionization<span> of a </span>base<span>.
</span>According to  Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺<span>). 
</span>PO₄³⁻ is Bronsted base and it can accept proton and become conjugate acid HPO₄²⁻.

If 842 grams of sodium hydroxide reacts with 750.0 grams of aluminum, how many grams of aluminum hydroxide should theoretically
Phantasy [73]

548.55 grams of aluminum hydroxide should theoretically form.

Explanation:

Balanced equation for the reaction:

3 NaOH + Al ⇒ Al(OH)3 +3 Na

DATA GIVEN:

mass of NaOH = 842 grams, atomic mass =39.9 grams/mole

mass of Al = 750 grams, atomic mass = 26.9 grams/mole

aluminum hydroxide theoretical yield = ?

Moles of NaOH reacted

number of moles = \frac{mass}{atomic mass of 1 mole}

putting the values in the equation

NaOH = \frac{842}{39.9}

           = 21.1 MOLES OF NaOH

Al = \frac{750}{26.9}

   = 27.8 moles

from the equation

 from 3 moles of NaOH 1 mole of Al(OH)3 is produced

21.1 moles of NaOH will react to give x moles of Al(OH)3

\frac{1}{3} = \frac{x}{21.1}

7.03 moles of Al(OH)3 is formed.

and

1 mole of Al(OH)3 is formed from 1 mole of Al in the reaction

so, 27.8 Moles will react to give give 27.8 moles of Al(OH)3 limiting reagent of the given reaction is NaOH

mass of Al(OH)3 =7.03 x 78 (atomic mass of Al(OH)3)

          = 548.55 grams

theoretical  yield from the given data is 548.55 grams

Help me pls due in 4 minutes thanks and have a great day!! :))))
Mamont248 [21]

Answer:

Its A, C and D

Explanation:

A= correct because when you add heat to a solid it starts to melt and turn to liquid

B= Incorrect because the more heat that's dded the faster the atoms in the object will move and that creates energy

C= Correct because the liquid is in fact changing to a gas as more heat is added.

D= Correct because as i explained in B the more heat added the more energy is there

Answer:

Creativity

Skepticism

Reasoning

Explanation:

Scientists must see a creative way to solve problems in the world. Scientists must also be skeptic about what is said, because if they were not, no one would disagree and the problems would never be solved. Reasoning is a must, as reasoning is involved in the scientific process and writing conclusions to their studies.

Hope this help!
