a) Protons are transferred in a covalent bond.
b) Electrons are shared in a covalent bond.
c) Electrons are transferred in a covalent bond.
d) Protons are shared in a covalent bond.
help please
Answer:
b) electrons are shared in a covalent bond
Explanation:
remember for ionic bonding, it occurs between a metal and a non-metal, we know that the metal donates electrons to the non-metal while the non-metal is the receiver.
the reason why the metal donates electron is usually because it has between 1-3 electrons on its valence shell and therefore there is a weaker attraction of the positive nucleus to the outermost electrons hence why it is readily donated.
the opposite occurs for the non-metals hence why it readily accepts electrons to become stable

The bonds that hold trna molecules in the correct three-dimensional shape are __________.
The bonds that hold tRNA molecules in the correct three-dimensional shape are hydrogen bonds.
What is hydrogen bonding?Hydrogen bonding is defined as a special category of attractive intermolecular forces generated from the dipole-dipole interaction between a hydrogen atom attached to a very strong electronegative atom and another strong electronegative atom.
For example, In water molecules, an H-atom is bound together by an electronegative O-atom. Hydrogen bonding in water molecules is due to the dipole-dipole interaction between the hydrogen atom of a water molecule and the oxygen atom of another water molecule.
The strength of hydrogen bonding is much more compared to dispersion force and dipole-dipole forces.
Therefore, intermolecular hydrogen bonding between bases of the tRNA molecules is in the correct three-dimensional shape.

PLEASE HELP ME!!! Describe the experiments that led to the determination that electrons act as both particles and waves. Explain why this revelation was important.
The experiment that led to the determination that electrons act as both particles and waves is Feynman's Double Slit Experiment.
What is the Feynman's Double Slit Experiment about?
Feynman anticipated that electrons would behave like particles when just one slit was open. When both slits were open, however, the electrons generated a distinctive pattern of light and black fringes on the detector due to wave interference.
Based on the American Physical Society, the earliest iteration of the double-slit experiment was performed in 1801 by the British polymath Thomas Young (APS). His work proved the interference of light waves and established that light was a wave rather than a particle.
The double-slit experiment is proof in contemporary physics that light and matter may exhibit properties of both conventionally defined waves and particles; moreover, it demonstrates the essentially probabilistic nature of quantum mechanical events.

if neither the volume nor the pressure of the system changes during the process, how is the change in internal energy related to the change in enthalpy
Change in enthalpy of the system is directly proportional to the change in internal energy.
What is enthalpy?
A thermodynamic system's enthalpy, which is one of its properties, is calculated by adding the system's internal energy to the product of its pressure and volume. It is a state function that is frequently used to monitor chemical, biological, and physical systems at a constant pressure that is conveniently given by the sizable surrounding environment. The energy necessary to determine the system's physical dimensions, or to make room for it by displacing its surrounds, is expressed by the pressure-volume phrase. Under typical conditions, the pressure-volume term is very small for solids and liquids and moderately small for gases.
The change in the enthalpy of the system during a chemical reaction is equal to the change in its internal energy plus the change in the product of the pressure times change in the volume of the system. Here it is given that change in pressure as well as change in volume is zero.Hence change in enthalpy of the system is directly proportional to the change in internal energy..

what mass of ammonium chloride must be added to a 0.500 l solution of 0.250 m ammonia to make a buffer with a ph of 9.26? kb (nh3)
The mass of ammonium chloride must be added to a 0.500 l solution of 0.250 m ammonia to make a buffer with a pH of 9.26 is 10.16 g.
given that :
pH = 9.26
molarity = 0.250
volume = 0.500 L
the formula for the pH is given as :
pH = pKa + log ( base / acid )
pKa for ammonia = 9.25
putting all the value in the equation we get:
9.26 = 9.25 + log ( 0.250 × 0.5 ) / NH₄Cl
moles of NH₄Cl = 0.19 mol
mass of NH₄Cl = molar mass × number of moles
mass of NH₄Cl = 53.49 × 0.19
mass of NH₄Cl = 10.16 g

In this particular problem, Molality is 10.74 m.
What is the difference between molality and molarity?
Despite the fact that both terms are used to describe the concentration of solutions, molality and molarity are not synonymous. The amount of solute dissolved in a litre of solution is known as its molarity. Molarity is denoted by the capital "M," and its formula is M=(# mol SOLUTE)/. (Liters of SOLUTION).
The amount of moles of solute per kilogramme of the SOLVENT, NOT the solution, is called molality. Molality is denoted by the lower case letter "m," and its formula is m=(# mole SOLUTE) /. (Kilograms of SOLVENT).
Most of the time scientists use either molarity or molality to represent solution concentration, but MOLALITY is preferred when the temperature of the solution varies. That is because MOLALITY does not depend on temperature, (Neither number of moles of solute nor mass of solvent will be affected by changes of temperature.) while MOLARITY changes as temperature changes.

Methyl orange might be selected as an indicator for the titration of a weak base with a strong acid. Can you estimate the ph at the equivalence point?.
Yes. The pH of 3.7 should be the equivalency point.
Methyl orange is employed as a strong acid and weak base indication for what reason?Methyl orange transforms from a basic to an acidic color during a strong acid weak base titration, making it a useful chemical indicator. In acidic and basic media, respectively, methyl orange exhibits red and yellow colors. In titration, the solution appears yellow at first because the pH is high.
Methyl orange is a frequently used pH indicator in titrations because of its easy-to-see color shift. Because it changes color at a weak acid's pH, it is frequently employed in acid titrations. Methyl orange turns red in an acidic medium while turning yellow in a basic one.
