Answer:
Blank 1: 1
Blank 2: 2
Blank 3: 1
Blank 4: 1
Explanation:
Assuming this is to balance the equation, write out the amount of each element you have on the reactants side and on the products side
Reactants Products
Ca 1 Ca 1
C 2 C 2
H 2 H 4
O 1 O 2
Comparing the two, we can see that hydrogen and oxygen have different amounts between reactants and products. Therefore, we need to multiply by some number to get the two equal. If we multiply the reactants by 2 we will get the correct amount in the products. So we put a 2 in front of the H₂O to signify this.
The balanced chemical reaction is
CaC₂ + 2 H₂O --> C₂H₂ + Ca(OH)₂

Answer:
<em>The correct option is the structure in the option D. </em>
Explanation:
Ammonia contains a single nitrogen atom bonded to three hydrogen atoms.
The structure present in option A shows a single nitrogen atom bonded with a single hydrogen atom hence it is not correct.
The structure in option B shows a nitrogen atom bonded to four hydrogen atoms hence it is also not correct.
The structure in option C shows a nitrogen atom bonded to two hydrogen atoms hence it is also not correct.
The structure in option D shows a nitrogen atom bonded to three hydrogen atoms which is the correct structure of ammonia (NH3).
Ethanol is added to the reaction mixture of base and fat in the manufacture of soap because it interferes with the formation of soap and making clarifying it making it translucent. It allows fatty acid to be partially mixed in the water where the base is being dissolved.
