Answer:
6
Explanation:
If there are 6 electrons and it has a balanced charge, there also must be six protons.
Answer:
<em>The accurate label for the solution is</em><em> </em><u><em>2.00 mol/L NaCl.</em></u>
Explanation:
Molrity = mass ÷ molar mass
Molar mass of NaCL = 58.44 g/mol
Weighed mass = 116.9g
⇒ Molarity of the solution = 
= 2.0M
<em />
<em>Therefore, the accurate label for the solution is </em><u><em>2.00 mol/L NaCl.</em></u>
Answer:
900 J/mol
Explanation:
Data provided:
Enthalpy of the pure liquid at 75° C = 100 J/mol
Enthalpy of the pure vapor at 75° C = 1000 J/mol
Now,
the heat of vaporization is the the change in enthalpy from the liquid state to the vapor stage.
Thus, mathematically,
The heat of vaporization at 75° C
= Enthalpy of the pure vapor at 75° C - Enthalpy of the pure liquid at 75° C
on substituting the values, we get
The heat of vaporization at 75° C = 1000 J/mol - 100 J/mol
or
The heat of vaporization at 75° C = 900 J/mol
Answer:
asexual cell
Explanation:there are mainly 2 types sexual and asexual i would say asexual because they grow without another parent and don't have a nucleus.
