Answer: Option (a) is the correct answer.

Explanation:

An atom with large atomic radius will be able to lose electrons more easily as the valence shell is away from the nucleus. Hence, force of attraction between the valence shell and nucleus will be less.

So, potassium being larger in size will be able to lose electrons easily as compared to bromine.

Hence, we can conclude that K will give up an electron more easily than Br.

The first choice is correct. K will give up electrons more easily, due to its smaller electronegativity.

zhannawk [14.2K]

Answer: 18g

Explanation:

1 mle of glucose combusts to give 6moles of CO2 and 6moles of H2O

C6H12O6 + 6O2-------- 6CO2 + 6H2O at STP.

Multiplying 6 by 3 moles we have 18 g of CO2

a sealed container filled with argon gas at 35 c has a pressure of 832 torr. if the volume of the container is decreased by a fa
lesya692 [45]

Answer:

If the volume of the container is decreased by a factor of 2 the pressure is is increased by the same factor to 1664 torr.

Explanation:

Here we have Boyle's law which states that, at constant temperature, the volume of a given mass of gas is inversely proportional to its pressure

V ∝ 1/P or V₁·P₁ = V₂·P₂

Where:

V₁ = Initial volume

V₂ = Final volume = V₁/2

P₁ = Initial pressure = 832 torr

P₂ = Final pressure  = Required

From V₁·P₁ = V₂·P₂ we have,

P₂ = V₁·P₁/V₂ = V₁·P₁/(V₁/2)

P₂  = 2·V₁·P₁/V₁ = 2·P₁ = 2× 832 torr = 1664 torr

If i start with 46 ml of 1.25 m hcl and dilute it to a volume of 250 ml, what is the concentration of my final solution
ikadub [295]
Equation: M1V1 = M2V2

Where M = concentration & V = volume

Step 1: Write down what is given and what you are trying to find

Given: M1 = 1.25M, V1 = 46mL, and V2 = 250mL
Find: M2

Step 2: Plug in the values into the equation

M1V1 = M2V2
(1.25M)(46mL) = (M2)(250mL)

Step 3: Isolate the variable (Divide both sides by 250mL so M2 is by itself)

(1.25M)(46mL) / (250mL) = M2

Answer: M2 = 0.23M

Which statements are true of the reactions in the Sun?
timurjin [86]

The correct statements which are true for the reactions in the Sun are that are fusion reactions and reactions occur because of very high temperatures.

<h3>What is nuclear fusion?</h3>

Nuclear fusion reactions are those reactions in which two species reacts with each other for the formation of new specie.

In the core of the sun, nuclear fusion of hydrogen atoms occur for the formation of helium molecules in the presence of high temperature.

Hence, the correct statements are they are fusion reactions and reactions occur because of very high temperatures.
