The atomic radius of magnesium is 150 pm. The atomic radius of strontium is 200 pm. What is the atomic radius of calcium

Choice (3) is correct: they exhibit the same chemical properties. Both samples are under identical conditions, so their densities remain unchanged. Gram-formula mass is an intrinsic property of the substance and does not vary. The volume would change if the mass changes.

The correct answer is C

NOT D

DON'T BE DECEIVED

Response:

            A covalent bond is formed when the outer electrons of two atoms are shared, enabling them to adequately fill their orbitals.

Clarification:

                   Covalent bonds occur between atoms with an electronegativity difference below 1.7. In this bonding type, one atom's valence electrons create a molecular bond with the other atom's valence electrons, leading to mutual sharing of electrons.

                   Covalent bonds can be non-polar, as seen in hydrogen and carbon bonding.

                   Conversely, covalent bonds can also be polar, such as the bond between hydrogen and chlorine, where the chlorine atom is more electronegative and draws electrons towards itself, resulting in a lower electron density on the hydrogen atom.

The correct answer is the fifth option. Energy transfers from the fire to the pot, subsequently to the water, and then to the peas.

Answer:

Here is an explanation related to the same question.

Explanation:

• According to Le Chatelier's principle , when the balance of a system is disturbed by external changes, the system adapts by altering the concentrations of its components in a manner that counteracts the disturbance, thus achieving a new stable equilibrium of concentration that differs from its previous state.
• Bromothymol blue is known to function as a phenolic compound that operates effectively as an acid in water solutions. Because it is classified as a weak acid, it should not react rapidly, while simultaneously establishing equilibrium with its largely unrelated form.

For such a weak diprotic acid, the typical economic expression can indeed be articulated as:

    ⇒  

• It can be ultimately shown through Le Chatelier's concept that when a strong acid is introduced, the complete disorientation of either component influences an increase in the proton levels within the medium.
• Likewise, it takes up protons throughout the medium leading to the breakdown of water each time a solution is introduced. Consequently, the concentration of particles in the medium decreases. To adjust for this change, the equilibrium shifts appropriately, thereby prompting further dissociation of the respective acid into its dianion in the presence of protons, aiming to nullify the initial disturbance.
