Answer:
Coconut palm trees thrive in environments with temperatures above 64 degree Fahrenheit, that is tropical areas. Southern Florida is an ideal place for coconut palm trees to grow because it is tropical enough for them.
Explanation:
B.)gas
C.)liquid
Answer:
solid
Explanation:
because solid has a definite shape and volume
Answer:
Liquid
Explanation:
This is because the intermolecular forces of attraction are strong enough to hold the molecules together but not so strong as to fix them into definite positions (as in solids). Instead, they possess fluidity and hence no definite shape.
Answer:
Colligative properties depend on the quantity of solute and solvent and the identity of the solvent.
Explanation:
Colligative properties are defined as a set of intensive physical properties that result from the interactions between solute and solvent that form a solution. In this group of properties, we can find the freezing point depression, boiling point elevation, osmotic pressure, and vapor pressure lowering.
The mentioned properties dependon the amount of solute and solvent (concentration) and the nature of the solvent. this fact can be pictured by the freezing point depression formula:
where is the freezing point of the pure solvent, is the freezing point of the solution,is the freezing point depression constant and m is the molality
In the equation, it can be seen that the change of temperature of the solution with respect to the pure solvent depends on the molality, which is the ratio of moles of solute and mass of solvent. Moreover, the change also depends on the freezing point depression constant that is a characteristic of the solvent.
B- active volcano
C- extinct volcano
D-lava filled volcano
Answer:
B active volcano
Explanation:
Answer: 8.25 moles of oxygen are produced.
Explanation: The reaction follows:
By Stoichiometry,
As, 4 moles of Aluminium is produced by 2 moles of aluminium oxide
11 moles of aluminium will be produced by =
Now, 2 moles of aluminium oxide produces 3 moles of oxygen, so
5.5 moles of Aluminium oxide will produce =
Hence, 8.25 moles of oxygen will be produced.
eight
four
six
The answer is: four.
For example compound carbon dioxide (CO₂):
Electron configuration of carbon: ₆C 1s² 2s² 2p².
Electron configuration of oxygen: ₈O 1s² 2s² 2p⁴.
Carbon atom is sp2 hybridized, it has three sp2 orbitals and one p orbital, they form four bonds.
Oxygen has two p orbitals, they form two bonds (one sigma and one pi bond).
p orbitals from carbon and oxygen overlap and form pi bond.
Answer:
Explained below.
Explanation:
Formula when magnesium reacts with hydrochloric acid is given by;
Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)
So, from the equation, we can see that the gas formed is hydrogen.
This hydrogen gas is collected by a method known as water displacement.
This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.
