Answer:
802.69 g
Explanation:
The molar mass of Barium nitrite is 229.34 g/mol, so 3.5 moles of it will have a mass of ...
3.5 mol × 229.34 g/mol = 802.69 g
Answer:
behavior of objects for which all existing forces are not balanced.
Explanation:
Answer:
32g
Explanation:
We have to remember that for percent (w/w) concentration we usually write;
Percent concentration= mass of solute/mass of solution ×100
Since mass of solute= 14.7 g and percent concentration = 32.2%
Then
Mass of solution= mass of solute × 100/ percent concentration
Mass of solution= 14.7 ×100/32.2
Mass of solution= 46.7 g
Since mass of solution = mass of solute + mass of solvent
Mass of solute= 14.7 g
Mass of solution = 46.7g
Mass of solvent = 46.7g -14.7g = 32g
The correct order of increasing dipole moment is BCl3 < BIF2 < BClF2.
What is dipole moment?
- The mathematical product of the separation of the ends of a dipole and the magnitude of the charges.
- More is the electronegativity of an atom more it will have pull of electrons towards itself. For example, in BCl3 electrons will be pulled towards chlorine atom as it is more electronegative than boron.Hence, the dipole moment is cancelled out. So, it will have zero dipole moment.
- In BIF2 and BClF2 , fluorine is more electronegative in nature and it is present in both the molecules.
- But chlorine is more electronegative that iodine atom. So, the dipole moment of BClF2 is more than the dipole moment of BIF2.

Answer:
Object 1 = Moving Towards Earth
Object 2 = Moving Away From Earth
Object 3 = Moving Towards Earth
Explanation:
When you look at emission spectras, look at where the observed lines are in comparison to the element (stationary) lines. Ones that have observed lines closer to the left are moving towards you and ones with observed lines closer to the right are moving away from you.
