Answer:
oxygen is an example of a diatomic molecule found in earth's atmosphere!
Explanation:
Answer:
0.05 mL
Explanation:
Initially, we have a concentrated solution of NaOH, to which we will add water to get a dilute one. To calculate the volume of the initial solution that we have to measure, we can use the dilution rule:
C₁ × V₁ = C₂ × V₂
where,
C₁ is the initial concentration (50% w/w; ρ = 1.52 g/mL)
V₁ is the initial volume
C₂ is the final concentration (0.1 M)
V₂ is the final volume (10 mL)
First, we have to calculate the weight/volume percentage and then the molarity of the first solution.
Now, we can apply the dilution rule.
A)16 protons
b)For neutron,the formula is given by A=Z+N where A is the mass no=32 and Z is atomic no=16 and N is the neutron no=? So to find N , A-Z=N so 32-16 so neutron is 16
c)sulphur
Answer:
This is an example of selective breeding
