<h3><u>Answer;</u></h3>

No ions present

<h3><u>Explanation;</u></h3>
  • Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge.
  • Atoms that gain electrons and therefore have a net negative charge are known as anions. Conversely, atoms that lose electrons have a net positive charge are called cations.
  • C12H22O11 (sucrose) is not an ionic compound, and therefore does not have any ions. Sucrose is a molecular compound.

Consider the rate law below.
Serga [27]

C. quadruples the rate

<h3>Further explanation</h3>

Given

The rate law :

R=k[A]²

Required

The rate

Solution

There are several factors that influence reaction kinetics :  

  • 1. Concentration  
  • 2. Surface area  
  • 3. Temperature  
  • 4. Catalyst  
  • 5. Pressure  
  • 6. Stirring  

The rate is proportional to the concentration.

If the concentration increased, the reaction rate will increase

The reaction is second-order overall(The exponent is 2)

The concentration of A is doubled, the reaction rate will increase :

r = k[A]² ⇒ r= k[2A]²⇒r=4k[A]²

<em>The reaction rate will quadruple.</em>

K3PO4+AgNO3--&gt; ???<br> Ba(HCO3)2+Ba(OH2)--&gt;
GuDViN [60]

<u>Explanation:</u>

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

  • <u>For 1:</u>

When potassium phosphate reacts with silver nitrate, it leads to the formation of silver phosphate and potassium nitrate.

The balanced chemical equation follows:

3AgNO_3+K_3PO_4\rightarrow Ag_3PO_4+3KNO_3

  • <u>For 2:</u>

When barium bicarbonate reacts with calcium hydroxide, it leads to the formation of barium carbonate, calcium carbonate and water

The balanced chemical equation follows:

Ba(HCO_3)_2+Ca(OH)_2\rightarrow BaCO_3+CaCO_3+2H_2O
