Answer:
0.058M is molarity of the solution
Explanation:
Molarity is defined as the ratio between the moles of solute (In this case, MgSO₄) and the liters of solution.
In the problem:
<em>Moles MgSO₄: 0.32 moles</em>
<em>Liters solution: 5.5L</em>
<em />
Molarity is:
0.32 moles / 5.5L =
0.058M is molarity of the solution
Answer:
true
Explanation:
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
Answer:
D.) molecule
<h3>When the same or different atoms combine together they for a molecule</h3>
Answer:
3) Ionic
Explanation:
The solid formed when a bond occurs between magnesium and oxygen is an ionic bond. This bond type occurs between a metal and non-metal.
- Magnesium is the metal
- Oxygen is the non - metal
- Due to the large electronegativity difference between the two species, the metal loses electrons which the non-metal oxygen gains
- They both complete their octet and electrostatic attraction leads to the formation of ionic bonds.
The answer is:
2.5 moles
The explanation:
when avogadro's number = 6.02 * 10^23
and when 1 mole of the sample will give → 6.02*10^23 atoms
So, ??? mole of the sample will give→ 1.52 x 10^24 atoms
∴ number of moles = (1.52 X 10^24) * 1 mole / (6.02X10^23)
= 2.5 moles
