An intensive property is a property that does not depend on the amount of the substance in a system being measured. Examples are density and color. The opposite is called extensive where the properties depends on the amount of a substance.

An example of commensalism is tick on a deer. Therefore, option A is correct.
What is commensalism ?
Another sort of symbiotic interaction is commensalism, in which one organism benefits and the other does not in any way suffer. Golden jackals will pursue tigers as they hunt in order to consume the tigers' leftovers.
The term "commensalism" is derived from the word "commensal," which in human social interaction refers to "eating at the same table," and which itself is derived through French from the Medieval Latin term "commensalis," which refers to "sharing a table," from the prefix com-, which means "together," and mensa, which refers to "table" or "meal."
The simplest definition of commensalism is that it is a form of symbiosis in which one organism gains while the other neither gains nor suffers harm. The three primary forms of commensalism are phoresy, metabiosis, and inquilinism.
Thus, option A is correct.

Answer:
22.1 g
Explanation:
The balanced reaction equation which serves as a guide in solving the problem is given as;
CaO(s) + 2NaCl(aq) ------> Na2O(s) + CaCl2(aq)
The question clearly specifies that sodium chloride is the reactant in excess. This means that calcium oxide should be used to calculate the theoretical yield of sodium oxide.
Number of moles of calcium oxide reacted = mass of calcium oxide / molar mass of calcium oxide
Molar mass of calcium oxide = 56.0774 g/mol
Mass of calcium oxide = 20.0g
Number of moles of calcium oxide = 20.0 g/ 56.0774 g/mol = 0.3566 moles
From the balanced reaction equation;
1 mole of calcium oxide produces 1 mole of sodium oxide
Therefore, 0.3566 moles of calcium oxide will produce 0.3566 moles of sodium oxide.
Mass of sodium oxide produced = number of moles × molar mass
Molar mass of sodium oxide= 61.9789 g/mol
Mass of sodium oxide = 0.3566 moles × 61.9789 g/mol
Mass of sodium oxide= 22.1 g
Answer:
22.1g
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CaO + 2NaCl —> Na2O + CaCl2
Next, we shall determine the mass of CaO that reacted and the mass of Na2O produced from the balanced equation.
This is illustrated below:
Molar mass of CaO = 40 + 16 = 56g/mol
Mass of CaO from the balanced equation = 1 x 56 = 56g
Molar mass of Na2O = (23x2) + 16 = 62g/mol
Mass of Na2O from the balanced equation = 1 x 62 = 62g
From the balanced equation above,
56g of CaO reacted to produce 62g of Na2O.
Finally, we can determine the theoretical yield of Na2O as follow:
From the balanced equation above,
56g of CaO reacted to produce 62g of Na2O.
Therefore, 20g of CaO will react to produce = (20 x 62)/56 = 22.1g of Na2O.
Therefore, the theoretical yield of Na2O is 22.1g

Hello!
Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).
We have the following data:
m (mass) = ?
n (number of moles) = 5.20 moles
MM (Molar mass of C6H12) ≈ 84.2 g/mol
Now, let's find the mass, knowing that:

I Hope this helps, greetings ... Dexteright02! =)
1 mole ---------- 84.2 g
5.20 moles ---- ?
Mass C₆H₁₂ = 5.20 * 84.2 / 1
Mass = 437.84 /1
= 437.84 g
hope this helps!
