PH is how you measure the concentration of an atom. 

Water is neutral, because it has a pH of 7.

An arctic weather balloon is filled with 22.6L of helium gas inside a prep shed. The temperature inside the shed is 7°C. The bal
Liono4ka [1.6K]

Answer : The new volume of the balloon is, 22.4 L

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T

or,

\frac{V_1}{V_2}=\frac{T_1}{T_2}

where,

V_1 = initial volume of gas = 22.6 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 7^oC=273+7=280K

T_2 = final temperature of gas = 5^oC=273+5=278K

Now put all the given values in the above formula, we get the final volume of the gas.

\frac{22.6L}{V_2}=\frac{280K}{278K}

V_2=22.4L

Therefore, the new volume of the balloon is, 22.4 L

0.50 mol A, 0.60 mol B, and 0.90 mol C are reacted according to the following reaction
algol [13]

Reactant C is the limiting reactant in this scenario.

Explanation:

The reactant in the balanced chemical reaction which gives the smaller amount or moles of product is the limiting reagent.

Balanced chemical reaction is:

A + 2B + 3C → 2D + E

number of moles

A = 0.50 mole

B = 0.60 moles

C = 0.90 moles

Taking A as the reactant

1 mole of A reacted to form 2 moles of D

0.50 moles of A will produce \frac{2}{1} = \frac{x}{0.50}

thus 0.50 moles of A will produce 1 mole of D

Taking B as the reactant

2 moles of B reacted to form 2 moles of D

0.60 moles of B reacted to form x moles of D

\frac{2}{2} = \frac{x}{0.6}

x = 2 moles of D is produced.

Taking C as the reactant:

3 moles of C reacted to form 2 moles of D

O.9 moles of C reacted to form x moles of D

\frac{2}{3} = \frac{x}{0.9}

= 0.60 moles of D is formed.

Thus C is the limiting reagent in the given reaction as it produces smallest mass of product.

Rank these photons in terms of increasing energy:<br> (a) blue (λ=453nm)
alexira [117]

The increasing order of photons in terms of energy is Er < Ey < Eb

A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.

By using the formula:

E = h * ν

E = h * c / λ

h = planks constant

c = speed of light

Since h * c is constant

E is inversely proportional to wavelength  λ

For blue:

λ = 453 nm

Eb= k / 453

where k is constant

For red:

λ = 660 nm

Er = k / 660

For yellow:

λ = 595 nm

Ey = k / 595

Therefore,

The increasing order of photons in terms of energy is

Er < Ey < Eb.

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).
