<span>Balancing the choices, we have as follows:

A. 3AgBr + GaPO4 → Ag3PO4 +GaBr3

B. 3H2SO4 + 2B(OH)3 → B2(SO4)3 + 6H2O

C. Fe + 2AgNO3 → Fe(NO3)2 + 2Ag

D. C2H4O2 +2O2 → 2CO2 + 2H2O

Therefore, the correct answers are option A and B. Hope this answers the question. Have a nice day.</span>

How many moles of H2O are needed to produce 5.6 mol of NaOH?<br> Na2O + H2O --&gt; 2NaOH
navik [9.2K]

Answer: 2.8 moles

Explanation:

The balanced equation below shows that 1 mole of sodium oxide reacts with 1 mole of water to form 2 moles of sodium hydroxide respectively.

Na2O + H2O --> 2NaOH

1 mole of H2O = 2 moles of NaOH

Let Z moles of H2O = 5.6 mole of NaOH

To get the value of Z, cross multiply

5.6 moles x 1 mole= Z x 2 moles

5.6 = 2Z

Divide both sides by 2

5.6/2 = 2Z/2

2.8 = Z

Thus, 2.8moles of H2O are needed to produce 5.6 mol of NaOH

The green areas on the diagram show the world's rainforests. What can you conclude about the location of rainforests?
Ber [7]

Answer:

Option A

They are located near the equator

Explanation:

From the diagram, we can observe that all the rain forest zones occur near the equator.

This is because on an annual basis, the equator receives the highest concentration of solar radiation in the whole Earth. This implies that the rate of evaporation of water from the water bodies present  is high, and consequently, the amount of rainfall is high also. This abundant sunshine and high rainfall  leads to the growth of the tropical rain forests at those regions

The pKapKa of cyclopentane is &gt; 60, which is about what is expected for a hydrogen that is bonded to an sp3sp3 carbon. Explai
aivan3 [116]

Answer and explanation:

cyclopentadiene is more acidic than cyclopentane

hydrocarbon compound are weak acid in nature

This relative acidity is explained by the stability of

cyclopentadienyl anion which is aromatic in nature

(check the attached image file 1)

To answer this question we must look at the stability of the anions that are formed when the compound lose proton.

All the electron in the cyclopentyl anion are localized.

In contrast, the aromatic cyclopentadienyl anion is a stable carbanion as a result of its aromaticity therefore making its conjugate acid a very strong acid compare to other compounds with hydrogen attached to sp³ carbons
