Answer:
Condensation and Depositon
Explanation:
Condensation is from gas to liquid
Deposition is from gas to solid
Explanation:
It shows , Hydrogen bonding , Since ,
The molecule of water have a strong electronegative atom of oxygen and a hydrogen atom ,
So , the electronegative oxygen atom can interact with the other hydrogen atom of the other water molecule .
The molecule of Carbon tetrabromide have polar bonds of carbon and bromine atom , but overall the molecule is non - polar in nature , due to its tetraderal structure , hence ,
the molecule shows only dispersion forces .
The molecule of dichloromethane has Dipole Dipole forces due to difference in electronegativity between atoms .
Answer:
52.8 g of O2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
4Al + 3O2 —> 2Al2O3
From the balanced equation above,
4 moles of Al reacted with 3 moles of O2 to produce 2 moles of Al2O3
Next, we shall determine the number of mole of O2 needed to react with 2.2 moles of Al. This can be obtained as follow:
From the balanced equation above,
4 moles of Al reacted with 3 moles of O2.
Therefore, 2.2 moles of Al will react with = (2.2 × 3)/4 = 1.65 moles of O2.
Thus, 1.65 moles of O2 is needed for the reaction.
Finally, we shall determine the mass of O2 needed as shown below:
Mole of O2 = 1.65 moles
Molar mass of O2 = 2 × 16= 32 g/mol
Mass of O2 =?
Mole = mass/Molar mass
1.65 = mass of O2 /32
Cross multiply
Mass of O2 = 1.65 × 32
Mass of O2 = 52.8 g
Therefore, 52.8 g of O2 is needed for the reaction.
Bohr's Model agree with Thompson's model because Bohr concluded that packets of energy are absorbed or emitted by the atoms when an electron changes shell. Thompson's conclusion states that atoms have small, negatively charged particles (referring to Electrons) as part of their internal structure.
Hey, for #1, it's 1, 1, 1 because it's already balanced!
For #2, it's 1, 2, 1, 1 since the product side has 2 Cl's but left side only had 1.
