Answer:
No
Explanation:
Are two atoms of the same element identical?
No they are not, for multiple reasons,
1) Heisenberg uncertainty principle: Electrons don't have a definite position, and direction of motion, at the same time. So we can only know of the two. Therefore the atoms are not identical in terms of the location or direction of motion at any fixed point in time.
2) Isotopes, while the number of protons in the nucleus determine the element, atoms of the same element can have different numbers of neutrons in their nuclei.
3) Electrons again, atoms can exist in energized states, therefore we may have a different number of electrons
The correct answer is - D. the insect touching the trigger hairs.
On this photos we have an example of an insect and a ''flesh-eating'' plant, where the insect is touching the trigger hairs of the plant's ''mouth'' and the plant quickly closes and traps the insect. All of the plants that have evolved to consume other living organism have a developed system that reacts on touch, so if an insect touches some of the parts of this system, usually a sticky liquid or hairs, it immediately reacts and closes, thus trapping the insect and starting to digest it.
The answer to this question is the second option

Answer:
2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of lithium phosphate and magnesium nitrate are mixed.
2 Li₃PO₄(aq) + 3 Mg(NO₃)₂(aq) ⇒ 6 LiNO₃(aq) + Mg₃(PO₄)₂(s)
The complete ionic equation includes all the ions and insoluble species.
6 Li⁺(aq) + 2 PO₄³⁻(aq) + 3 Mg²⁺(aq) + 6 NO₃⁻(aq) ⇒ 6 Li⁺(aq) + 6 NO₃⁻(aq) + Mg₃(PO₄)₂(s)
The net ionic equation includes only the ions that participate in the reaction and insoluble species.
2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)
Answer:
A. VSEPR theory assumes each atom molecule has a geometry to help minimize the repulsion between the electrons within the valence shell of the central atom.
B. Repulsion determines the molecular shape as the electrons are negativley charged. The negativity makes the atoms spread out as much as possible.
C. Lone electron pairs have greater repelling effects as they are closer to the nucleus of the central atom unlike bonding pairs.
