Answer: New pressure inside the flask would be 148.8 kPa.
Explanation: The combined gas law equation is given by:
As the flask is a closed flask, so the volume remains constant. Temperature is constant also.
So, the relation between pressure and number of moles becomes
- Final conditions: When additional 3 puffs of air is added
Putting the values, in above equation, we get
The charge is +2 because there are 2 more protons than electrons. The name of the element is Lead because the number of protons identifies the chemical element. Lead's symbol is Pb.
Answer: The concentration of the KOH solution is 1.01 M
Explanation:
According to neutralization law:
where,
= basicity of = 1
= acidity of KOH = 1
= concentration of HCl = 3.00 M
= concentration of KOH = ?
= volume of HCl = 35.3 ml
= volume of KOH = 105.0 ml
Putting the values we get:
Thus the concentration of the KOH solution is 1.01 M
Answer:
Carbon dioxide comprises carbon, a nonmetal, and two oxygen atoms, which are also nonmetals, forming a covalent compound with covalent bonds connecting the atoms.
