What is the main type of heat transfer.
krek1111 [17]

Conduction

Convection

Radiation

Explanation:

The main types of heat transfer are heat transfer by conduction, convection and by radiation.

These forms of heat transfer has different modes of application.

  • Conduction is a form of heat transfer in solids. It requires a material medium to dissipate. Here, heat flows from a hot end to a cold end.
  • Convection is a form of heat transfer in fluids i.e liquids and gases. In convection, heat is transferred due to density differences between heated fluids.
  • Radiation does not involve material medium. It uses the electromagnetic waves to dissipate heat.

1. How does the Key change for a weak acid?
Tema [17]

The weak acid will have fewer ions than the strong acid of similar concentration.

The chemical reactions for a weak acid and a strong acid is given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

<h3>What are strong and weak acids?</h3>

Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.

Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.

Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.

The equation of the dissociation of strong acids and weak acids are given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.

What are the coefficients of the equation below when it is balanced?
strojnjashka [21]

3, 2, 1, 6

Explanation:

To balance the chemical equation the number of atoms of each element  

entering the reaction have to be equal to the number of atoms of each  

element leaving the reaction, in order to conserve the mass.

In our case we have:

3 CaCl₂ + 2 Na₃PO₄ → Ca₃(PO₄)₂ + 6 NaCl

So the stoechiometric coefficients will be:

3, 2, 1, 6
