115 mL of a 2.35 M potassium
fluoride (KF) solution is diluted with 1.28 L of water. What is the new concentration in molarity?
? M KF

Answers

The new concentration : = 0.194 M

Further explanation

Given

115 mL(0.115 L) of a 2.35 M Potassium  fluoride (KF)

1.28 L of water

Required

The new concentration

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

M₁V₁=M₂V₂  

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = volume of the solution after dilution

V₂=0.115 + 1.28 = 1.395 L

Input the value :

M₂ = (M₁V₁)/V₂

M₂ = (2.35 x 0.115)/1.395

M₂ = 0.194

Answer: 0.194

what’s the correct answer !!

Answers

Answer:

From my side the correct option is "A"

Explanation:    Reasons for its correction are ,

1)  Highly reactive: Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability.

2)Small size:  Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.

8. What is the molar mass of carbon dioxide, Co2(g)? How many grams of carbon

Answer:

CO2 molar mass=44.01g

3 moles CO2 = 132.03g

Explanation:

CO2 molar mass = 12.01+2(16.00)=44.01g

3 moles CO2 * (44.01 g CO2)/(1 mol CO2)=132.03g

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.

If the pressure increases to 350 kPa and the volume remains constant, what will the new temperature be?

Round your answer to one decimal place.

Answers

Answer:

The new temperature will be 565.83 K.

Explanation:

Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.

In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:

[tex]\frac{P}{T} =k[/tex]

When an ideal gas goes from a state 1 to a state 2, it is true:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

P1= 180 kPaT1= 291 KP2= 350 kPaT2= ?

Replacing:

[tex]\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}[/tex]

Solving:

[tex]T2=350 kPa*\frac{291 K}{180 kPa}[/tex]

T2= 565.83 K

The new temperature will be 565.83 K.

What is the chemical formula for sodium sulfate

Answers

Answer:

Na2So4

Na is group 1, so has a charge of 1+

Sulphate’s formula is SO4 2-,

because sulphate has double the charge of Na, you need two Na’s to make it equal.

Therefore it’s Na2SO4

Which equation is NOT balanced?

B. H2 + H2 + O2® H2O + H2O
C. 2H2 + O2® H2O
D. 4H2 + 2O2® 4H2O

Answers

Answer:

C

Explanation

On the reactants side there is 4 Hydrogen atoms in total and two oxygen atoms on the left however on the right there is two hydrogen atoms and one oxygen atom. Leaving this equation unbalanced

The equation that is NOT balanced is [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex]. The correct answer is option C.

In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.

In equation A, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation B, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation C, there are 4 hydrogen atoms and 2 oxygen atoms on the reactant side, but only 2 hydrogen atoms and 1 oxygen atoms on the product side. Therefore, it is not balanced.In equation D, there are 8 hydrogen atoms and 4 oxygen atoms on both the reactant and product sides, so it is balanced.

In conclusion, equation C.  [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex] is the one that is NOT balanced. It has an unequal number of oxygen atoms on the reactant and product sides.
