What is the pH of a solution with a concentration of 5.2 × 10–8 M H3O+?
lora16 [44]

Answer : The pH of a solution is, 7.28

Solution : Given,

Concentration of hydronium ion, H_3O^+ = 5.2\times 10^{-8}M

pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.

pH=-\log [H_3O^+]

Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.

pH=-\log (5.2\times 10^{-8})=7.28

Therefore, the pH of a solution is, 7.28

What general rule can be followed when choosing a type of solvent to dissolve a particular solid?
Fittoniya [83]
 <span>the polarity of the solute or the solvent. 

for example: 
oil will not mix with water because oil molecules are nonpolar however water moleculses are polar. so, they will not mix with each other. 

when we put sodium chloride in water, sodium chloride will be easily dissoved. because both sodium chloride and water are polar. 

in other case, if we put sodium chloride and hexane together. sodium chloride will not dissove in hexane, because hexane is a nonpolar solvent. 

finally, if we try to mix hexane and bromine together, they will mix uniformly. because both hexane and bromine are nonpolar. (note: most diatomic molecules are nonpolar, such as hydrogen gas, oxygen gas, chlorine gas, etc. ) 

so just remember, nonpolar and nonpolar will dissovle each other. and polar and polar will dissolve each other.</span>

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 have chemists changed the periodic table over time?
mrs_skeptik [129]

They have used added new elements to the  table .

<u>Explanation:</u>

As new elements are discovered chemists add them to the period table leading to the periodic table undergoing continuous modifications. When the first periodic table in the world was formed, very few elements were known to humankind. Earlier periodic tables thus contain lesser number of elements than the modern ones.

Mendeleev's periodic table contained 63 elements arranged in the increasing order of their atomic masses. Modern periodic tables have far more number then the older ones like that of Mendeleev's and the elements are arranged in the order of their atomic numbers.

The uses of isolates of crude oil
nataly862011 [7]

Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms.

<h3>What are the uses of crude oil?</h3>

We use petroleum products to run our vehicle like car, bikes, boats, aeroplanes and many more other things. In the industrial sector, the petrochemical industry uses petroleum as a raw material (a feedstock) to make products such as plastics, polyurethane, solvents, and hundreds of other intermediate and end-user goods.

1. It is used for Food Production

2. It is used for Transportation

3. It is used in Clothing Materials

4. It is used as Products in our Home

5. From the Crude Oil we can extract the oil, petrol, jet fuel and many other things

So we can conclude that: Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms.
