Name the five methods used for the formation of salts??

Chemistry
1 answer:
Viefleur [7K]3 years ago
5 0

Explanation:

In chemistry, a salt is a chemical compound consisting of an ionic assembly of cations and anions.[1] Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic, such as chloride (Cl−), or organic, such as acetate (CH

3CO−

2); and can be monatomic, such as fluoride (F−) or polyatomic, such as sulfate (SO2−

4).

Which of the following animals are an example of coevolution? *
pychu [463]

Acacia ant and acacias animals are an example of coevolution

Coevolution is the reciprocal evolutionary change in a set of interacting population over time resulting from the interaction between those population and an example of coevolution that is not characteristics of an arm race but one which provides a mutual benefit to both a plant species and insect is that of the acacia ant and acacia plant and many cases of coevolution can be found between plants and insects

Is H3O+ polar or non polar? (explain please.)?
pishuonlain [190]
The overall molecule is Polar because the shape of the molecule is Trigonal Pyramidal, which means it has the lone pair electrons. Becuase of the lone pair the pulling is unequal.   

H3O+ has 3 polar bonds. 
To know if the bonds are polar or nonpolar find the difference of the element's electronegativity charge. 
H has electronegativity charge of 2.2, and O has 3.4.
Always subtract the smaller number from the greater one. 
So 3.4 - 2.2 = 1.2 
If the difference is from 0-0.4 the bond is nonpolar, but if it's from 0.5-1.9 the bond is polar. 
So, 1.2 is polar bond. So H3O+ has 3 polar bonds, and the overall molecule is polar too. 

A simple way to know if it's polar or nonpolar is to draw the lewis dot structure, and use VSEPR.

what volume of 1.75 m hcl in liters is needed to react completely (with nothing left over) with 0.750 l of 0.100 m na2co3 ?
Evgesh-ka [11]

The balance chemical equation is :

2HCL + Na2CO3 -----> 2NaCl + H2O + CO2

According to Question,

Given,

Molarity of HCL = 1.75 m

Sodium Carbonate (Na2CO3) = 0.100 m

For finding out the molarity,

c = n solute / Vsolution  => n = c.Vsolution

nCO^2-3 = 0.100 mol L^-1 . 0.750 L = 0.0750 moles of CO^2-3

0.0750 moles of CO^2-3 . 2 moles H3O^+ / 1 mole CO^2-3

= 0.150 moles of  H3O^+

As we have already know the molarity of HCL , we easily calculate what volumes by many moles.

c = nsolute / Vsolution => Vsolution = nsolute / c

VH3O^+ = 0.150 moles / 1.75 mol L^-1 =  0.0857 L

Idk what is asking ?

It's asking about air currents and temperature and how they affect each other. Since the land is hotter than the water during the day, it will create different pressures that force air to move. <span>The wind will blow from the higher pressure over the water to lower pressure over the land </span>causing<span> the </span><span>sea breeze. The opposite happens at night, and that causes a land breeze.
