Answer:

C) H2S

Explanation:

In chemistry, the dissolution of one substance in another is dependent on the magnitude of intermolecular interaction between the two substances.  Hence, if two substances do not interact in one way or the other, then one can not dissolve the other.

Let us consider the fact that NH3 is a polar molecule and it is a general principle that like dissolves like. Hence, only H2S which is also a polar molecule can effectively interact with  NH3 due to dipole-dipole interaction between the two molecules.

Also, ammonia reacts with hydrogen sulphide as follows;

2NH3 + H2S → (NH4)2S

Hence H2S is more likely to dissolve in NH3.

Answer: 16 neutrons

Explanation: The atomic number for any element is the number of protons in its atomic nuclei. In a neutral atom, the number of electrons are the same as the number of protons. The atomic mass (mass number) is the sum of the protons and neutrons in the nucleus. Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers.

So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).

This isotope is phosphorus-31, which has atomic number 15.

Answer:

1.47 atm

Explanation:

From the question.

Applying

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

Where P = pressure, V = volume, T = temperature, n = number of moles, R = Molar gas constant

Makr P the subject of the equation

P = nRT/V................ Euqation 2

Given: V = 50.0 L, n = 3.00 mol, T = 25°C = (273+25) = 298K,

Constant: R = 0.082 atm.L.K⁻¹mol⁻¹

Substitute these values into equation 2

P = (3×298×0.082)/(50)

P = 73.308/50

P = 1.46616

P ≈ 1.47 atm

Explanation:

Answer:

There are 3.08 moles of hydrogen gas in the tank

Explanation:

As we know

[tex]PV = nRT[/tex]

where P is the pressure of the gas in atm

V is the volume in liters

n is the number of moles

R is the gas constant = 0.08206 L·atm/K·mol

and T is the temperature in Kelvin.

Substituting the given values in above equation, we get -

[tex]1.51 * 25 = n * 0.08206 * 149\\n = 3.08[/tex]

There are 3.08 moles of hydrogen gas in the tank

The chemical formula of Benadryl is [tex]C_{17}H_{21}NO[/tex]

1 mol of Benadryl has 17 mol of hydrogen

2.5 mol of Benadryl has 17*2.5 = 42.5 moles of hydrogen.

Mols are peculiar chemical definitions. You have to be careful what you are talking about. You are given mols of Benadryl, which is the whole molecule. Whole molecule means the Carbon Hydrogen Nitrogen and Oxygen

Each mol of Benadryl contains 17 mols of carbon, 21 moles of hydrogen, 1 mol of nitrogen and 1 mol of oxygen

Explanation:

The electron geometries of water and ammonia are both based on a tetrahedron. The central atom in ammonia is nitrogen which is surrounded by four electron pairs; three bond pairs and one lone pair. In water, the central atom is oxygen surrounded by four electron pairs also; two bond pairs and two lone pairs. The presence of four electron pairs on the central atom of each molecule means that their electron geometries are both tetrahedral according to Valence Shell Electron Pair Repulsion Theory.

However, due to the presence of lone pairs, the molecular geometry of water is bent(angular) while the molecular geometry of ammonia is trigonal pyramidal.

Answer:

Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.

Explanation:

Answer:

Explanation: NiCl2 (aq) + 2NaOH (aq)

                      Ni(OH)2 (s) + 2NaCl (aq)

M(NiCl2)= 0.500 M

M(NaOH)=0.200 M

V(NiCl2)= 28.0 mL

According to balanced reaction:

2*number of mol of NiCl2 =1*number of mol of NaOH

2*M(NiCl2)*V(NiCl2) =1*M(NaOH)*V(NaOH)

2* 0.50 M * 28.0 mL = 1* 0.2 M* V(NaOH)

V (NaOH) =  140 mL

Answer : 140 mL

Answer:

C. 2H₂ + O₂ ⇒ 2H₂O

Further explanation

Conservation of mass states that in a closed system, the masses before and after the reaction are the same. So it can be concluded

mass of the reactants = mass of the products

mass cannot be created or destroyed

The number of atoms involved in a reaction remains the same⇒ number of moles also the same

chemical equation in balanced form

So let's see which of the several options , which one has the same number of atoms on both sides of the equation

2H₂ + O₂ ⇒ 2H₂O

H ⇒ left 4, right 4

O ⇒ left 2, right 2

so the equation is in balance and represents the Law of Conservation of Mass

Answer:

the air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

Answer:

When magnesium ions are broken off the solid lattice and go into solution, there is enough attraction between the 2+ ions and the water molecules to get co-ordinate (dative covalent) bonds formed between the magnesium ions and lone pairs on surrounding water molecules… making it more conductive than sodium.

The bond between hydrogen (H) and oxygen (O) (option 3: H-O) has the highest electronegativity difference (1.24). Therefore, the H-O bond is the most polar among the given choices.

The polarity of a chemical bond depends on the electronegativity difference between the two atoms involved. The greater the electronegativity difference, the more polar the bond.

Let's compare the given bond options:

(1) C-O: The electronegativity of carbon (C) is approximately 2.55, and the electronegativity of oxygen (O) is approximately 3.44. The electronegativity difference is 0.89.

(3) H-O: The electronegativity of hydrogen (H) is approximately 2.20, and the electronegativity of oxygen (O) is approximately 3.44. The electronegativity difference is 1.24.

(2) F-F: Fluorine (F) is the most electronegative element with an electronegativity of 3.98. Since both atoms in this case are fluorine, the electronegativity difference is 0.

(4) N-H: The electronegativity of nitrogen (N) is approximately 3.04, and the electronegativity of hydrogen (H) is approximately 2.20. The electronegativity difference is 0.84.

From the options provided, the bond between hydrogen (H) and oxygen (O) (option 3: H-O) has the highest electronegativity difference (1.24). Therefore, the H-O bond is the most polar among the given choices.
