Moles of glucose = Molarity x volume solution
= 4.5 x 1.5
= 6.75 moles.
Hope this helps, have a great day ahead!
Answer:
When energy is removed in liquid water then it will solidify since heat is given off by the system to its surrounding. It is an exothermic process where the enthalpy decreases since heat is taken off. So liquid water becomes ice in an exothermic process.
Explanation:
The mass of magnesium in
atoms is 240 g.
Answer: Option A
<u>Explanation:</u>
First, we have to convert the atoms to moles of magnesium.
We know that
atoms are present in 1 mole of magnesium. So,


Thus,


Thus, 240 g of Magnesium is present in
atoms.
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
