Answers:

(a) The explanatory variable is the change in the temperature .

The response variable is the coral survivance.

(b) The explanatory variable is quantitative.

The response variable is categorical.

Explanation:

A quantitative variable is those that can take a range of values. In this case, the temperature may vary across a range of values associated with the survival of coral reefs.  

A categorical (also known as qualitative) variable is characterized to present finite states. In this case, the coral reefs can survive or not depending on their responses to changes in the temperature.

Answer:

Correct answer is Li

Explanation:

Lithium reacts with chlorine to form Lithium chloride.

$2Li+Cl_{2} \to 2LiCl$

This is a redox (Oxidation -Reduction) reaction

$2Li^{0} \to 2Li^{+2}+2e^{-}$ - Oxidation$Cl_{2}^{0}+2e^{-} \to 2Cl^{-}$  - Reduction

Hence the reducing agent in this reaction is Li

Balance each reaction and write its reaction quotient, Qc:(b) POCl₃(g) ⇄ PCl₃(g) + O₂(g)
Komok [63]

When we balance the given equation

      POCl₃(g) ⇄ PCl₃(g) + O₂(g)

We will get

      2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

Solution:

Balancing the given equation

      POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of O

      2POCl₃(g) ⇄ PCl₃(g) + O₂(g)

Balancing the number of P and Cl

      2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

We get the balanced equation

      2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)

The reaction quotient will be

     Qc = [product] / [reactant]

     Qc ​= [PCl₃(g) + O₂(g)] / [POCl₃(g) ]

88.5 mol of P4O10 contains how many moles of P?
Dennis_Churaev [7]
Looking at the formula, each mol of P4O10 contains 4 mol of P, so 
(58.5 mol P4O10) x (4 mol P/ 1 mol P4O10) = 234 mol
