2.5 , The reaction is
2K+Cl2=2KCl
Thus the number of moles of potassium and potassium chloride is same
c) are often metals
liquids are fairly good thermal conductors while gases and things like wood and plastic foam are poor conductors of heat.
Answer:
1.7 M
Explanation:
Concentration is the number of moles of solute dissolved in 1 L of solution
Concentration = number of moles of solute / volume of solution
Number of moles of solute needs to be calculated first
Mass of methanol - 12.5 g
Molar mass of methanol - 32 g/mol
Number of methanol moles - 12.5 g / 32 g/mol = 0.39 mol
Therefore concentration is = 0.39 mol / 0.230 L = 1.7 mol/L
Concentration is 1.7 M
1.)b
2.)true
3.)false
are the answer don't take me on my word
Hello, the answer to your question is simple
Selective breeding (if we're talking about dogs in this example) always means the breeder is particular on not allowing: certain genentic mutations in the D.N.A, what color that animal is, if the animal is in good health and any genetic disorders.
