Metal is 1 of the best electrical conductors and this because , heat travels fast and locks heat inside of it . It will not transfer heat to anything other than the metal itself
Answer:
Explanation:
an atom consists of prontons electrons and neutrons.
The nucleus is positively charged proven by the Rutherford experiment. The protons and neutrons are in the nucleus so the charges cancel out. The electrons are surrounded in the shells that are negatively charged.
Answer:
false
Explanation:
not all science is good, or has good effects
Answer:
Final concentration = 10 M
Explanation:
Given data:
Initial volume = 100 mL
Initial molarity /concentration= 5 M
Final volume = 50 mL
Final molarity/concentration = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume
M₂ = Final molarity
V₂ = Final volume
Now we will put the values.
5 M × 100 mL = M₂ × 50 mL
500 M.mL = M₂ × 50 mL
M₂ = 500 M.mL / 50 mL
M₂ = 10 M
