Why is NCl3 not soluble in water?

Answers

Answer:

Explanation:

NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.

Answer:

A polar solute dissolves into a polar solvent and a non-polar compound dissolves into a non-polar solvent, this rule is known as "like dissolves like".

When propane is reacted in the presence of oxygen gas, the products of this combustion reaction are: A. CO + H2O B. CO2 + H2O C. C2H4 + H2O D. CH4 + H2O

Answers

Answer:

B. CO2 + H2O

Explanation:

Propane is an hydrocarbon as it contains only v=carbon and hydrogen atoms.

Whenever an hydrocarbon reacts with oxygen or undergoes a combustion reaction, two products are always formed only,

These two products are;

Carbon dioxide (CO2) and water (H2O)

This means the correct option is option B.

A clam farmer has been keeping records of the water temperature and the number of clams developing from fertilized eggs. The data is recorded above.


What is the dependent variable?

What is the independent variable?

What is the optimum temperature for clam development?

Answers

Answer:

The dependent variable is the number of clams developing from fertilized eggs.

The independent variable is the water temperature

The optimum temperature for clam development is 30 degrees centigrade.

Explanation:

The graph of the number of clams developing from fertilized eggs and water temperature is attached to this answer.

The independent variable is being manipulated in an experiment. As it changes, it produces a corresponding change in the dependent variable.

Here, the water temperature is the independent variable. As it changes, the number of clams developing from fertilized eggs (dependent variable) also changes alongside.

The optimum temperature is the temperature at which the greatest number of clams developing from fertilized eggs is produced. We can see from the graph that this temperature is 30 degrees centigrade.

Ο Α. Η
O B. S
O c. O
O D. Na

Answers

D. Na

There are 2 Na in the reactants, and only 1 Na in the product.

In the given unbalanced reaction, the number of sodium is not balanced. There must have two sodium in the product side also. The correct formula of sodium sulphate is Na₂SO₄.

What is mass conservation law?

According to the law of conservation of mass, the total mass of a system is conserved. Thus, mass can neither be created nor be destroyed. Therefore, for a chemical reaction, the total mass in the product side must be equal to the total mass in the reactant side.

The balanced equation of  a chemical reaction thus, obeying the mass conservation law where, each element have to be equal in number in both sides.

In the given reaction, the number of Na in reactant side is 2 and that in product side is 1 only. Thus total mass of sodium is not conserved. It can be corrected as Na₂SO₄ in the product side.

Substance A dissociates 100% in water to produce H3O+ ions while substance B dissociates 25% in water to produce OH- ions. What can be determined from this information?
A:Substance A is a strong acid and substance B is a weak base
B:Substance A is a weak acid and substance B is a strong base
C:Substance A is a strong base and substance B is a weak acid
D:Substance A is a weak base and substance B is a strong acid

Answers

Answer:

A:Substance A is a strong acid and substance B is a weak base

Explanation:

From this information, we can conclude that substance A is a strong acid and substance B is a weak base.

A strong acid is one that ionizes completely in solution. Most strong acids are usually concentrated. 100% dissociation is a complete ionization.

A weak base ionizes slightly in an aqueous solution. 25% dissociation is weak ionization.

element x bonds with phosphate in a ratio of 3 ions of element x to 2 phosphate ions. what kind of ion does element x form?

Answers

Answer:

The kind of ion is X2+ ( where the ion is formed as a result of the loss of two valence electrons)

Explanation:

The ratio of ions of the element X to the phosphate ions is 3 to 2

So what we have as formula of these will be;

X3(PO4)2

Generally we have the phosphate ion formula as; PO4^3-

So for this formula above to be possible then the element x will have a formula of its ion X2+

What is the frequency of a photon with an energy of 3.38 x 10-19 J?​

Answers

Hey There!_____________________________________Answer:

[tex]\huge\boxed{5.1x[tex]10^{14}[/tex]Hz}[/tex]

_____________________________________DATA:

E = [tex]3.38 x 10^{-19}[/tex]

h = [tex]6.625x10^{-34}[/tex]

f = ?

_____________________________________SOLUTION:

Energy of Photon is given by,

                                   

                                   E = hf

Rearrange the equation,

                             

                                    f = [tex]\frac{E}{h}[/tex]

where,

           E = energy

           h = planck's constant

           f = frequency

------------------------------------------------------------------------------------------------------------

Substitute the variable in the equation,

 

                                 f = [tex]\frac{3.38x10^{-19}}{6.62x10^{-34}}[/tex]

Simplify the equation,

                               

                                  f = 5.10 x 10^14 Hz

An isotope of Cesium -137 has a half-life of 30 years. If 1.0 g of Cesium – 137 disintegrates over a period of 60 years, how many grams of Cesium- 137 would remain?

Answers

Answer:

Explanation:

Radioactive decay follows the equation:

Ln [A] = -kt + ln [A]₀

Where [A] is amount of isotope after time t: Our incognite,

k is rate constant: ln 2 / Half-life = 0.0231 years⁻¹

t are 60 years

[A]₀ is initial amount of isotope: 1.0g

Replacing:

Ln [A] = -kt + ln [A]₀

Ln [A] = -0.0231 years⁻¹*60 years + ln 1.0g

ln [A] = -1.386

[A] = 0.25g

It increases because the electrons are held tighter together by the higher effective nuclear charge. The electrons are held in lower energy orbitals and closer to the nucleus and more tightly bound and harder to remove from the atom.
