Answer: The answer is C. replacement
This would be an example of a replacement type of reaction. As the iron is replaced with the aluminum in the reaction.
Explanation:
Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest) or a push and pull motion.
Explanation:
Answer:
0.5 moles
Explanation:
u will get molar mass = 95.2 I think
then number of moles = molar mass÷ mass
=95.2÷180=0.5
Answer:
0.0073 g
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.010 M
Volume = 25 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 25×10⁻³ L
Thus, moles of HCl :
Moles of HCl = 0.00025 moles
Considering the reaction shown below as:-

2 moles of HCl reacts with 1 mole of 
So,
1 moles of HCl reacts with 1/2 mole of 
Also,
0.00025 moles of HCl reacts with
mole of 
Mole of
= 0.000125 moles
Molar mass of
= 58.3197 g/mol
Mass = Moles*Molar mass =
= 0.0073 g
Answer:
8 electrons
Explanation:
As per the <u>octet rule</u>, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.
