Explanation:
The amount of CD is 35 g, and the amount of AC is 40 g.
Answer:
Single Replacement reaction
Explanation:
Reaction Given:
2Na + 2HCI ------> H₂ + 2NaCl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
2Na + 2HCI ------> H₂ + 2NaCl
In this reaction two reactant combine and give 2 products.
Reactant of the reaction
Na = Sodium
HCl = Hydrochloric acid
Product of the reaction
NaCl = sodium chloride
H₂ = hydrogen gas
So,
That sodium metal react with hydrochloric acid and produce salt and water gas
Type of Reaction:
This is a Single Replacement reaction, in which Sodium metal (Na) replace the Hydrogen (H) of the other compound and form Sodium Chloride salt (NaCl) and hydrogen liberate in the form of gas.
Yes chloride is an element.... hope this helps!!
We have to answer based on basic concept on electron.
The correct answer is: Since electrons repel each other, electrons pairs will be as far apart as possible.
We know, electrons are negatively charged particles and negatively charged particles repel to each other.
When electrons which are of similar charge repel each other, they go far apart from each other..
