Answer:
32.73%
Explanation:
To solve this problem, first find the molar mass of Al(OH)₃.2H₂O
Atomic mass of Al = 27g/mol
O = 16g/mol
H = 1g/mol
Molar mass = 27 + 3(16 + 1) + 2(2(1) + 16)
= 27 + 51 + 36
= 114g/mol
Percentage composition = 
x 100 = 32.73%
Answer:
<h3>The answer is 1.03 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 257.3 g
volume = 250 cm³
We have
We have the final answer as
<h3>1.03 g/cm³</h3>
Hope this helps you
Answer: Sulphur and Oxygen
Explanation: Sulphate ion is 
. It is polyatomic ion which is formed by the combination of sulphur and oxygen elements in the ratio of 1:4.
It is negatively charged species and thus is named by the name _ate at the end.
It usually exists with positively charged species to get stable. eg: ferrous sulphate (
)
Answer:This is what's known as a metal displacement reaction: the lead substitutes for the copper and ends up precipitating out of solution as insoluble lead (II) sulfate. ... The weight of copper deposited was 15.86gm.
Explanation:
Answer:
The products will be;
CO₂ + H₂O + NaC₂H₃O₂
Explanation:
We are given;
Two reactants NaHCO₃ and HC₂H₃O₂
We are supposed to determine the products;
- We need to know that hydrogen carbonates reacts with acids to give water, carbon dioxide and a salt as the products.
Therefore;
- In this case, sodium hydrogen carbonates (baking soda) reacts with acetic acid to form water, carbon dioxide and sodium acetate.
- The equation for the reaction is;
NaHCO₃ + HC₂H₃O₂ → CO₂ + H₂O + NaC₂H₃O₂
- Therefore, the products of the complete reaction between sodium hydrogen carbonate and acetic acid are CO₂ + H₂O + NaC₂H₃O₂
