Answer and explanation;
Na - metal
Cl - poisonous gas
NaCl - cyrstaline solid that is edible
An emergent property is a property which a collection or complex system has, but which the individual members do not.
Water emergent properties: cohesion & adhesion, versatile solvent, temperature moderation, freezing.
The properties of a compound can be very different from the properties of the elements that make them, for example, Sodium is an explosive metal, and Chlorine is a toxic gas, however, sodium chloride is a Delicious table salt!
696.32 mmHg is the final pressure of the gas.
<h3>What is an ideal gas equation?</h3>
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
Given data:
= 720 mmHg
= ?
= 2.5 mol
= 3.2 mol
= 34 L
= 45 L
Formula
Combined gas law
= 696.32 mmHg
Hence, 696.32 mmHg is the final pressure of the gas.

Answer:
B. The carbons on either side of the double bond are Pointed in opposite directions
The polar water molecules pull apart the ions of the acid or base.
Question:
How many atoms are in
1.50g ofAI
Number of Mole:
Generally, the ratio within the total mass of a chemical substance and the molar mass of that chemical substance is utilized to calculate the total number of moles of the substance. The mathematical expression of the number of the mole is shown below,
n=m/M
Here, n is the total number of moles, m is the total mass and M is the total molar mass.
Answer and Explanation:
Given data
The mass of the aluminum is
m =1.50g
Note- The molar mass of the aluminum is
M=26.98g/mol
Since n=m/M
n= 1.50/26.98
n=0.0556
So the answer is A
