<h2>question  1</h2>

Mg  + 2HCl→ MgCl2 + H2

after balancing the coefficient for H2   is 1

<em><u>explanation </u></em>

since 1  is in front of H2  it is the coefficient for H2


question  2

 the reaction is single replacement

<u><em>explanation</em></u>

  • because  single replacement  occurs when one element  replaces another.  
  • for  the reaction of  Mg + 2HCl→MgCl2 +H2   Chlorine  

<h2>  Question  3</h2>

The   coefficient  of  H2  is 3

<em><u>explanation</u></em>

  • from  the balanced chemical reaction
  • that is  N2 +3H2 →2NH3  the coefficient  in  front of H2  is   3
<h2 /><h2>  question  4</h2>

N2 + 3H2 → 2NH3  is  a  synthesis  reaction

<u><em>explanation; </em></u>

Synthesis reaction  occurs  when two or more  reactants combine  to form a single product.

  • N2  reacted with  H2  to form   NH3 (ammonia) hence  it is  an example of synthesis reaction.

<h2>question 5</h2>
  1. The sign  that shows that a chemical reaction  has occurred  is    color change, change  in temperature  and  formation of a  gas (bubble)

color change  change in temperature, formation  of  precipitate  and formation  of  a gas(bubble)  is always   an indicator of an occurrence of a chemical  change.

<h2>Question 6</h2>

H2S is not  a strong acid

<u><em>explanation</em></u>

  • strong acid undergo a complete electrolysis  when dissociate in water  for example  HNO3  
  • weak acid  undergo  a partial electrolysis  when dissociate in water   for example  H2S

<h2>question 7</h2>

feels slippery  is not  a property of an acid

<u><em>explanation</em></u>

  • feel  slippery is an example of a  base
  •  The properties of an acid are
  1. sour taste
  2. changes the color of an indicator
  3. usually react with metal among  others
<h2>  Question   8</h2>

detergent with a PH of about  10  is a  <u><em>basic</em></u>

<em><u>explanation</u></em>

  • Base has    a Ph  which range  from 7.1 to  14
  • since  the detergent  has a PH of 10 is a basic
<h2>Question 9</h2>

The balanced chemical equation  for the synthesis  of NaBr is

2Na  + Br2 →2 NaBr

<u><em>explanation</em></u>

 This is because the  equation obey the law of mas  conversation

   for  example it has  2 atoms of  Na   in both reactant and product side

<h2>Question 10</h2>

 reacts with metals  is not  a common  property of  a base

 <u><em>Explanation</em></u>

  • base has  
  1. bitter taste,
  2. feels slippery
  3. turn red litmus paper blue  among others
<h2>  question  11</h2>

Hydrochloric acid have  a PH   in  0-6 range

<u><em>explanation</em></u>

  • HCl  is a strong  acid  
  •  acid has a PH  which are below PH  of 7  hence HCl  has a PH which range from 0-6

<h2>Question 12</h2>

A brand  shampoo  which has a PH between  5 -6 is  a weak  acid

  •    generally acid  has  a PH below   7
  • weak  acid  has a PH of between  5 -6  therefore  brand  shampoo  is a weak  acid
<h2>question 13</h2>

The PH  that indicate  a  solution  of a  base is a PH of 12

 <em><u>Explanation</u></em>

  • base  has a PH  which range between 7-14, hence  a  PH of 12   indicate that it is a  Base

Please balance this. urgent
Colt1911 [192]
Mg+2HCl-->H2+MgCl2 you would it have to make it so each is equal on each side you would add a 2 on left in front of HCl because on the other side there is already 2 H and 2Cl so just put a 2 in front of HCl

The most reactive metal in group three
photoshop1234 [79]

Actinium is the most reactive element or metal in group 3.

Explanation:

Reactivity of an element or metal is defined as its tendency to loose or gain atoms. Group 3 elements consist of metal. We know that reactivity of metal increases as we go down to the bottom of the column.

group 3 metals have 3 electrons in valence shell. They react by loosing 3 electrons. it has oxidation state of +3 and are electropositive.

Group 3 consists of scandium, yttrium, lanthanum and actinium.

Actinium is called actinide.
