Answer:
Explanation:
Driving a car (burning gas is a chemical change) and almost all the plastics we use are made by chemical reactions of different components.
Answer:
Silver Acetate would be the Limiting Reagent.
Explanation:
The balance chemical equation for the given double displacement reaction is as;
HCl + AgC₂H₃O₂ → AgCl + HC₂H₃O₂
Step 1: <u>Calculate Moles of Starting Materials:</u>
Moles of HCl:
Moles = Mass / M.Mass
Moles = 72.9 g / 36.46
Moles = 1.99 moles
Moles of AgC₂H₃O₂:
Moles = 150 g / 166.91 g/mol
Moles = 0.898 moles
Step 2: <u>Find out Limiting reagent as:</u>
According to balance chemical equation.
1 mole of HCl reacts with = 1 mole of AgC₂H₃O₂
So,
1.99 moles of HCl will react with = X moles of AgC₂H₃O₂
Solving for X,
X = 1.99 mol × 1 mol / 1 mol
X = 1.99 mol of AgC₂H₃O₂
Hence, to completely consume 1.99 moles of Hydrochloric acid we will require 1.99 moles of Silver Acetate, But, we are provided with only 0.898 moles of Silver Acetate. This means Silver Acetate will consume first in the reaction therefore, it is the LIMITING REAGENT.
Answer is: There are more reactants and one product of the reaction. The reactants may be elements or compounds. The product is always a compound.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
For example, balanced chemical reaction: Ba + F₂ → BaF₂.
In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
Second chemical reaction: CaO(s) + H₂O(l) → Ca(OH)₂(aq).
One molecule is produced from two molecules.
(A) Na2CO3
(B) NaHCO3
(C) H2CO3
(D) HF
(E) SO3
(F) CuSO4
(G) H2SO4
(H) H2S

0.1 moles of chloride ions were involved in the reaction if 25.0 mL of a 2.00 M CaCl2 solution is used for the reaction.
Explanation:
Data given:
volume of Ca
= 25 ml 0r 0.025
molarity of the calcium chloride solution = 2M
number of chloride ions =?
Balance chemical reaction:
Ca + 2 ⇒
number of moles in 25 ml is calculated as:
molarity = 
number of moles of calcium chloride = molarity x volume
putting the values in the equation:
number of moles = 2 x 0.025
= 0.05 moles of calcium chloride
1 mole of Ca decomposes as 1 calcium ion and 2 chloride ions
so 0.05 moles will have x moles of chloride ion
= 
x= 0.1
0.1 moles of chloride ions will be involved in the reaction.
