Increasing the concentration of reactants generally increases the rate of a reaction because particles

This increases the rate of rxn because the particles, because according to the Collision Theory, the rate of rxn is proportional to number of effective collisions between the reactant molecules.

Why do the protons identify the element and not the electrons or the neutrons?

Lunna [17]

Protons identity the element because the number of protons gives us the atomic number of each element

If I add 475mL of water to 75.0mL of a 0.315M NaOH solution, what will the molarity of the diluted solution be?

pantera1 [17]

Answer is: the molarity of the diluted solution 0,043 M.
V(NaOH) = 75 mL ÷ 1000 mL/L = 0,075 L.
c(NaOH) = 0,315 M = 0,315 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 0,075 L · 0,315 mol/L.
n(NaOH) = 0,023625 mol.
V(solution) = 0,475 L + 0,75 L.
c(solution) = 0,023625 mol ÷ 0,550 L.
c(solution) = 0,043 mol/L.

sp2- 3,4,5,6,7,8,9,10,11,12,14,15,17

sp- 0

Explanation:

Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties (Chemlibretexts).

Carbon atoms that are singly bonded are sp3 hybridized, carbon atoms that are doubly bonded are sp2 hybridized while carbon atoms that are triply bonded are sp hybridized.

Sp3 hybridized atoms have a tetrahedral geometry, sp2 hybridized atoms have a trigonal planar geometry while an sp hybridized atom has a linear geometry.

The hybridization state of each atom in the compound has been shown in the answer section.
