Predict the products of each reaction, and whether the solution at equilibrium will be acidic, basic, or neutral.1. P4O10 + 6H2O
77julia77 [94]

<u>Answer:</u>

<u>For 1:</u> The product is phosphoric acid and the solution is acidic in nature.

<u>For 2:</u> The product is sodium hydroxide and the solution is basic in nature.

<u>For 3:</u> The product is nitric acid and the solution is acidic in nature.

<u>Explanation:</u>

For the given options:

(1): When diphosphorus pentoxide reacts with water, it leads to the formation of phosphoric acid, which makes the solution acidic in nature.

The chemical equation for the reaction follows:

P_4O_{10}+6H_2O(l)\rightarrow 4H_3PO_4(aq)

(2): When disodium oxide reacts with water, it leads to the formation of sodium hydroxide, which makes the solution basic in nature.

The chemical equation for the reaction follows:

Na_2O+H_2O(l)\rightarrow 2NaOH(aq)

(3): When dinitrogen pentoxide reacts with water, it leads to the formation of nitric acid, which makes the solution acidic in nature.

The chemical equation for the reaction follows:

3N_2O_5+3H_2O(l)\rightarrow 6HNO_3(aq)

How many moles of NO2 form when<br> 63.25 g N2O5 decompose?<br><br> 2N₂O54NO₂ + O₂
KonstantinChe [14]

Answer:

1.1713 moles

Explanation:

RFM of N2O5=108

Moles of N2O5= mass/RFM= 63.25/108=0.5856 moles

Mole ratio of N2O5:NO2= 2:4

Therefore moles of NO2= 4/2*0.5856= 1.1713 moles

what term best describes the type of reaction that happens when a molecule or compund reacts with another molecule or compound,
Ludmilka [50]
<span>The answer to this question would be: a double replacement reaction

In double replacement reaction or metathesis, the reaction will result in two new compound. The cation from the molecule reaction is switching with the cation from other molecules. 
In contrast to the double replacement reaction, in single replacement reaction the molecule made in just one. In this case, the compound is just swapping its molecule with a more reactive one, results in a more stable compound.</span>

The total number of valence electrons in the phosphate ion is
Vitek1552 [10]

Answer:

32

Step-by-step explanation:

There are two ways you can count the valence electrons.

A. From the Periodic Table

1 × P (Group 15)               =   5

4 × O (Group 16) = 4 × 6 = 24

+3 e⁻ (for the charges)   = <u>  3</u>

                              Total = 32

B. From the Lewis structure

In the <em>Lewis structure</em> (below), each line (bond) represents a pair of bonding electrons, and each dot represents an unbound electron (half a lone pair).

5 lines (bonds)                    = 5 × 2 = 10

3 single-bonded O atoms = 3 × 6 = 18

1 double-bonded O atom              = <u>  4</u>

                                              Total = 32
