Which molecule could form a coordinate covalent bond with a proton (h )?

Answer:

A chlorine (Cl-) molecule could make a coordinated covalent bond with a proton (H +, in this case) forming hydrogen chloride (HCl).

Explanation:

Covalent bonds occur when there is electron sharing between atoms, making all atoms that participate in this type of bond stable, but in the case of coordinated or dative covalent bond, the atom that has available pairs of electrons and is not performing Sharing them with another atom can “donate” these free electrons to any other atom, thereby performing a simple covalent bond and a coordinated or dative covalent bond, where electron (s) transfer from one atom to the other. This type of chemical bond is quite common and often occurs with chlorine, sulfur, phosphorus, among other various chemical elements. As an example we can cite the bond between chlorine and hydrogen to form hydrogen chloride.

For a coordinated covalent bond to occur it is necessary for one of the atoms to share a pair of electrons with another atom, and at the same time assign one or more electrons to another atom, which only participates in the bond receiving the electrons.

Molecule is the smallest particle of a compound or an element with similar properties as the element or the compound. Covalent bond (dative bond) is a bond that is formed due to the sharing of electrons between atoms. Coordinate covalent bond is a type of covalent where electrons shared during bond formation comes from one atom. In this case a molecule of H2O would form a coordinate bond with H+ because the oxygen contains a lone pair of electrons forming H3O+.

Acute radiation can be healed by developing cells (white blood cells) in the body. During Chronic radiation immense amount of energy is released into your body causing division and break down of cells which can cause cancer and internal bleeding and cannot be cured depending on the amount released.

What mass of glucose would you need (in g) to have 0.8 mol, given that the molar mass of glucose is 180 g mol-1?
Verizon [17]
<h3>Answer: 144 g</h3>

Explanation:

  Mass of glucose = moles × molar mass

∴ Mass of glucose = 0.8 mol × 180 g mol⁻¹

                               =  144 g

∴ the mass of glucose you need to have 0.8 mol of glucose = 144 g

Complete the sentences to explain what’s happening at different portions of the heating curve.
Neporo4naja [7]

Particles of the substance have the most kinetic energy when the substance is(a)1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled(b)1. Solid.

Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy. During freezing, a substance loses a lot of potential energy so solid has the least potential energy.

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens
poizon [28]

Answer:

<u>It increases by a factor of four</u>

Explanation:

Boyle's Law : At constant temperature , the volume of fixed mass of a gas is inversely proportional to its pressure.

pV = K.......(1)

pV = constant

Charles law : The volume of the gas is directly proportional to temperature at constant pressure.

V = KT

or V/T = K = constant ....(2)

Applying equation (1) and (2)

\frac{PV}{T}=K

\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}

According to question ,

T2 = 4 (T1)

V2 = V1

Put the value of T2 and V2 , The P2 can be calculated,

\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{1}}{4T_{1}}

V1 and V1 cancel each other

T1 and T1 cancel each other

We get,

P1=\frac{P2}{4}

or

P2 = 4 P1

So pressure increased by the factor of four
