A. If the mass of Hydrogen is 1 amu, what is the mass of Hydrogen in the reactant side of the equation above?

B. what is the mass of Hydrogen on the product side of the equation above?

Answer: b because Potential energy is converted to kinetic energy as a stationary object begins to move.

Explanation:

Answer: Solubility of NaOH is greater and there are more OH- ions in solution.

Explanation: Reactions : NaOH (s) ⇒ Na+ (aq) + OH- (aq)

Mg(OH)2 (s) ⇒ Mg2+ (aq) + 2 OH-(aq)

Although in same amount of moles, Mg(OH)2 produces

two (OH-)-ions in water solution, solubility of Mq(OH)2 is smaller.

Concentration [OH-]ions is smaller in saturated  water solution

of Mg(OH)2

Answer:

Option D, Calcium and Aluminum levels

Explanation:

The coal fired power plant releases huge amount of particulate and gaseous emissions such as mercury, sulphur dioxide, nitrogen oxide etc. When there is rain, these gaseous and particulate matter comes to the ground along with rain water and pollute the soil. There are also chances of acid rain due to the presence of sulphur dioxide. Polluted soil and acid rain negatively impact the growth of the plants and causes leaching of Aluminium thereby decreasing the availability of calcium for the plants. Thus, the trees die. Hence, if the amount of Aluminium and Calcium in soil is determined, one can easily deduce the cause of death of trees.

Hence, option D is correct

Answer:

38 and [Kr] 5s2.

Explanation:

The number of electrons and the electronic configurations are the same for the three isotopes of Strontium because in isotopes number of neutron increases not number of proton or electron. Isotope of element having the same atomic number but with different atomic masses due to increase the number of neutrons in each isotope. So the number of electron in all isotopes are the same i.e. 38 and the electronic configuration is also the same i.e. [Kr] 5s2.

gravitational force is most responsible for binding together an atom’s protons and neutrons.

In physics, gravity (from Latin gravitas 'weight') is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is by far the weakest of the four fundamental interactions, approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light.

On Earth, gravity gives weight to physical objects, and the Moon's gravity causes tides in the oceans. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. Investigation into the effects of weightlessness has shown that gravity may play a role in immune system function and cell differentiation within the human body.

The gravitational attraction between the original gaseous matter in the Universe allowed it to coalesce and form stars which eventually condensed into galaxies, so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become weaker as objects get farther away.

a selectively permeable membrane

Explanation:

Answer:

Lower the pH slightly

Explanation:

The mixture of HF, hydrofluoric acid and KF, potassium fluoride produce a buffer that is defined for the equilibrium:

HF(aq) → H⁺(aq) + F⁻(aq)

The buffer can maintain the pH of a solution despite the addition of strong bases or acids.

The reaction of HF with Ca(OH)2 is:

2HF + Ca(OH)2 → 2H2O + CaF2

That means the calcium hydroxide is decreasing the concentration of HF. Based on the equilibrium, the H+ and F- ions will decrease in order to produce more HF. As H+ is decreasing due the equilibrium and not for the addition of a strong base, the pH is decreasing slightly.

Explanation:

Answer:

(C) NO2 has covalent bonds.

Answer:

c. increased as the temperature is increased

Explanation:

The average kinetic energy of a sample of water molecules is increased as the temperature is increased. Hence, option C is correct.

The average kinetic energy of the particles in a gas is proportional to the

temperature of the gas. Because the mass of these particles is constant,

the particles must move faster as the gas becomes warmer.

The average kinetic energy of gas molecules is directly proportional to

absolute temperature only; this implies that all molecular motion ceases

if the temperature is reduced to absolute zero.

Hence, option C is correct.

3. molarity=2.41molL

Explanation:

Molarity=Moles of soluteLiters of solution

Moles=0.289

Solution=120mL=0.12L

Therefore,

Molarity=0.289mol0.12L≈2.41molL

4. 1.169 mol/L

Explanation:

From the question given, we obtained the following information:

Volume = 0.075 L

Mole of CuCo = 0.0877 moles

Molarity =..?

Molarity is simply defined as the mole of solute per unit litre of the solution. It is represented mathematically as:

Molarity = mole /Volume

With the above formula, we can obtain the molarity of the solution as follow:

Molarity = 0.0877 mol / 0.075 L

Molarity = 1.169 mol/L

Therefore, the molarity of the solution is 1.169 mol/L
