According to the bohr model of the atom, the single electron in what motion of a hydrogen atom circles the nucleus

What explains the observation that FADH2 oxidation yields one less ATP than NADH oxidation by the Electron Transport System

Allisa [31]

Answer:

Check explanation

Explanation:

During the Electron Transport System occur in the mitochondrial membrane, oxygen in this reaction is been reduced to water and ATPs are being produced.

The quinone form or the oxidized form of Flavin Adenine Dinucleotide(FAD) is the FADH2. While Nicotinamide adenine dinucleotide is the acronym for NADH. NADH is a good donating substance/agent.

It has been observed that FADH2 produce two(2) ATP while NADH produces three(3) ATP. The reason for this observation is that the production of electron in the FADH2 is at the lower enegy level. Because of this it can not transfer its electron to the first complex .

While;

NADH is at the higher energy level and it can directly transfer its electron to the first complex.

If the speed of a vehicle increases by 22%, by what factor does its kinetic energy increase?

Mila [183]

Answer:

The kinetic increases by 48.84 %

Explanation:

The expression for the kinetic energy is:-

$K.E.=\frac{1}{2}\times mv^2$

Where, m is the mass of the object

v is the velocity of the object

Let the new velocity is:- v'

v is increased by 22 %. Thus, v' = 1.22 v

So, the new kinetic energy is:-

$K.E.'=\frac{1}{2}\times mv'^2=\frac{1}{2}\times m{1.22}^2=\frac{1}{2}\times mv^21.4884=1.4884K.E.$

<u>Thus, the kinetic increases by 48.84 %</u>

At a festival, spherical balloons with a radius of 280. Cm are to be inflated with hot air and released. The air at the festival

evablogger [386]

Answer:

8608.18 balloons

Explanation:

Hello! Let's solve this!

Data needed:

Enthalpy of propane formation: 103.85kJ / mol

Specific heat capacity of air: 1.009J · g ° C

Density of air at 100 ° C: 0.946kg / m3

Density of propane at 100 ° C: 1.440kg / m3

First we will calculate the propane heat (C3H8)

3000g * (1mol / 44g) * (103.85kJ / mol) * (1000J / 1kJ) = 7.08068 * 10 ^ 6 J

Then we can calculate the mass of the air with the heat formula

Q = mc delta T

m = Q / c delta T = (7.08068 * 10 ^ 6 J) / (1.009J / kg ° C * (100-25) ° C) =

m = 93566.96kg

We now calculate the volume of a balloon.

V = 4/3 * pi * r ^ 3 = 4/3 * 3.14 * 1.4m ^ 3 = 11.49m ^ 3

Now we calculate the mass of the balloon

mg = 0.946kg / m3 * 11.49m ^ 3 = 10.87kg

The amount of balloons is

93566.96kg / 10.87kg = 8608.18 balloons

How many sodium ions are present in 325 ml of 0.850 m na2so4?

NISA [10]

Answer:

$Na^+_{ions}=3.33x10^{23}Na^+_{ions}$

Explanation:

Hello,

In this case, for the given molarity and volume of such solution, the moles of sodium sulfate are computed below:

$n_{Na_2SO_4}=0.850\frac{mol}{L}*0.325L=0.276molNa_2SO_4$

Now, by using the Avogadro's number, the ions result:

$Na^+_{ions}=0.276molNa_2SO_4*\frac{2molNa^+}{1molNa_2SO_4} *\frac{6.022x10^{23}Na^+_{ions}}{1molNa^+} \\\\Na^+_{ions}=3.33x10^{23}Na^+_{ions}$

Best regards.

What is the molar mass of Ga2(SO3)3?

Misha Larkins [42]

Answer:

The molar mass of Gallium Sulfite is 379.6356

Explanation:

Molar Mass can often be found on the periodic table, however, this is specific to single elements. You can however find the molar mass by dividing the mass(g) by the amount of substance(mol).
