Zinc chloride (ZnCl2) and hydrogen (H2) are the products of a single replacement reaction. What are the reactants of this reacti
Juli2301 [7.4K]

 The reactants  of the reaction  of single   replacement  that  produces ZnCl₂ and H₂  is   Zn  + 2HCl

Explanation

  In  a single replacement  reaction  is  a  chemical  reaction whereby  an element  react  with compound  and take  the place of another element  in that compound.

zn   displaces  H   from  HCl  to form  ZnCl₂  and  H₂  according  to below  equation.

Zn  +2HCl  →  ZnCl₂ + H₂

Which of the following is not a part of the ideas john dalton proposed in his model
NNADVOKAT [17]

The following which is not a part of  Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

<h3>What is Dalton atomic theory?</h3>

Dalton has proposed his theory in three parts and each part stated that

The first portion of his theory asserts that all stuff is made up of indivisible atoms.

According to the second section of the theory, all atoms of a given element have the same mass and characteristics.

Compounds, according to the third section, are combinations of two or more different types of atoms.

Dalton has given three laws

  • Law of conservation of mass
  • Law of definite proportion
  • Law of multiple proportion

Thus, the following which is not a part of  Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

To learn more about Dalton atomic theory, refer to the link below:

Phosphoric acid is neutralized by potassium hydroxide according to the following reaction:
iren2701 [21]

Answer:

The answer to your question is 1.33 M

Explanation:

Data

Volume of H₃PO₄ = 24 ml

[H₃PO₄] = ?

Volume of KOH = 16 ml

[KOH] = 2 M

1 M H₃PO₄ = 3.0 M H⁺

Balanced chemical reaction

             KOH  +  H₃PO₄   ⇒   K₃PO₄  +  H₂O

Process

1.- Calculate the moles of KOH

Molarity = moles / volume

-Solve for moles

moles = Molarity x volume

-Substitution

moles = 2 x 16/1000

-Simplification

moles = 32/1000

-Result

moles = 0.032

2.- Calculate the moles of H₃PO₄

              1 mol of KOH --------------- 1 mol of H₃PO₄

 0.032 moles of KOH  --------------   x

                 x = (0.032 x 1) / 1

                 x = 0.032 moles of H₃PO₄

3.- Calculate the concentration of H₃PO₄

Molarity = 0.032 / 0.024

-Result

Molarity = 1.33
