Answer:

C. ATP.

Explanation:

During the process of aerobic cellular respiration, energy is said to be released in three main stages: glycolysis, Krebs cycle and oxidative phosphorylation (electron transport chain). The electron transport chain produces the most energy and it involves the transfer of electrons through series of complex proteins.

As the electrons move through the individual complexes, energy is lost to form a proton gradient (H+). The proton gradient powers the synthesis of ATP from ADP as catalyzed by ATP synthase.

Answer:

B.electrostatic repulsion by gold nuclei

Explanation:

According to Rutherford's experiment, a thin gold foil was bombarded with alpha particles. Some of the particles passed through the foil undeviated, some were scattered through large angles while some bounced backwards.

It follows that the particles that bounced backwards must have encountered a massive particle of like charge.

The atom is composed of a nucleus which contains positively charged particles. Some of the alpha particles which are positively charged particles bounced back when they encountered the positively charged particles in the nucleus.

Answer: The correct option is B (electrostatic repulsion by gold nuclei).

Explanation:

In the Rutherford's experiment, he used positively charged particles called alpha particles to bombard an atom in order to find out what is inside the atom. Together with two other scientists, Geiger and Marsden, they used a narrow beam of alpha particles emitted from a radioactive source to bombard a thin gold foil. The scattering of the particles from the gold foil was detected by a movable zinc sulphide screen which could be rotated to various positions around the foil.

Each time an alpha particle hit the screen, a visible flash of light or scintillation was produced. This was observed by a microscope attached to the screen. It was then observed that some of the particles followed a straight path through the gold foil while a few where scattered in a backward direction. This was as a result of electrostatic repulsion by gold nuclei which occurs due to the greater part of the mass of the atom was concentrated in a minute nucleus with positive charge.

The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over.

Following are the solution to the given question:

Explanation:

Its maximum oxidation zone is exceptionally stable and has the greatest ability to charge density, while fluoride and oxide ions are the largest particles with the largest durability of charge.

Or it might be assumed as oxygen and fluorine are the system particle atoms that have the highest electron number of metals.

Answer:

Cl

Explanation:

n for Mg=m:Mm

=65.8:24

=2.74mol

n for Cl=m:Mm

=45.7:70

=0.65mol

According to the number of moles we can say that the limiting reagent is Cl as it has few moles.

Limiting agents are the reactant that determines the amount of the product in a reaction. In the reaction between magnesium and hydrochloric acid, the limiting reagent is HCl.

A limiting reagent is a substance that restricts or determines the amount of product formation in a reaction. They are the reactants with less number of moles and get consumed in the reaction before the other reactant.

The reaction between magnesium and hydrochloric acid is given by,

Mg(s) + 2HCl(aq)  → MgCl₂(aq) + H2(g)

Here, 1 mole of Mg and 2 moles of HCl are required to produce 1 mole of magnesium chloride.

The moles of Mg,

= 65.8 g ÷ 24.305

= 2.707 mol

And, moles of HCl

= 45.7 g ÷ 36.458

= 1.253 mol

The stoichiometric ratio Mg : HCl = 1:2

Hence, Mg = 2.707 ÷ 1 = 2.707  and HCl = 1.253 ÷ 2 = 0.6265

Therefore, HCl is the limiting reagent.

Answer:

9.97×10⁻⁴ atm

Explanation:

Applying,

PV = nRT............... Equation 1

Where P = pressure, V = volume, n = number of moles of air, R = molar gas constant, T = Temperature.

make P the subject of the equation

P = nRT/V............ Equation 2

From the question,

Given: V = (11×12×8) ft³ = 1056 ft³ = (1056×28.3168) = 29902.5 L, T = 25°C = (25+273) = 298 K, n = 35.41/29 = 1.22 mole

Constant: R = 0.082 atm.L/K.mol

Substitute these values into equation 2

P = 1.22×0.082×298/29902.5

P = 9.97×10⁻⁴ atm

It's O2 which is oxygen....

Answer:

A chemical reaction that has a positive ΔH is said to be endothermic , while a chemical reaction that has a negative ΔH is said to be exothermic . What does it mean if the ΔH of a process is positive? It means that the system in which the chemical reaction is occurring is gaining energy.

Answer:

False because it is chemical change

when ph decrease that means acidity increase

when ph increase that means basicity increase

Answer:

1.48 moles of SeCl6 are needed

Explanation:

Based on the reaction:

SeCl6 + O2 → SeO2 + 3Cl2

1 mole of SeCl6 reacts producing 3 moles of Cl2.

To solve this question we need to use the conversion factor:

1mol SeCl6 = 3mol Cl2

As we want to produce 4.45 moles of Cl2, we need:

4.45 mol Cl2 * (1mol SeCl6 / 3mol Cl2) =

The steps involved in the manufacture of sulphuric acid by contact process:

(1) Sulphur (or iron pyrites) are burnt in air to form sulphur dioxide.

  S+O2→SO24FeS2+11O2→2Fe2O3+8SO2

(2) Catalytic oxidation of sulphur dioxide to sulphur trioxide.

  2SO2+O2V2O52SO3ΔrHo=−196.6kJ

The reaction is reversible and exothermic.

(3) Sulphur trioxide is dissolved in 98% sulphuric acid to form oleum (fuming sulphuric acid). 

  SO3+H2SO4→H2S2O7

(4) Oleum is diluted with water to form sulphuric acid of desired concentration.

    H2S2O7+H2O→2H2SO4

Answer:

113.17 g

Explanation:

This can be solved using the Ideal Gas Equation:

PV=nRT

First step is to calculate the volume of the cylinder in L:

V=πr²h

V= π (11.5)² (140)

V= π (132.25) (140)

V = π (18.515)

V = 58,166.588 cm³ = 58.2 L

Then, convert kpa into atm:

1 kpa = 0.00987 atm

108 kpa = 1.06588 atm

Then, plug all of your values into the Ideal Gas Equation to solve for moles:

(1.06588)(58.2)=n(0.082057)(294)

62.034=n(24.125)

2.571357513=n

Finally, convert the moles into grams

2N = 28.0134 amu

O = 15.999 amu

_______________

44.0124 amu

(2.571357513moles)(44.0124 amu) = 113.17 g
