Answer:
True
Explanation:
The first artificial use of a PGR was to stimulate the production of flowers on pineapple plants. They are now used widely in agriculture. Plant hormones are also used in turf management to reduce the need to mow, to suppress seedheads, and to suppress other types of grass.
Answer:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Answer is: <span>the molarity of the diluted solution 0,454 M.
</span>V₁(NaOH) = 100 mL ÷ 1000 mL/L = 0,1 L.
c₁(NaOH) = 0,75 M = 0,75 mol/L.
n₁(NaOH) = c₁(NaOH) · V₁(NaOH).
n₁(NaOH) = 0,75 mol/L · 0,1 L.
n₁(NaOH) = 0,075 mol
n₂(NaOH) = n₁(NaOH) = 0,075 mol.
V₂(NaOH) = 165 mL ÷ 1000 mL/L = 0,165 L.
c₂(NaOH) = n₂(NaOH) ÷ V₂(NaOH).
c₂(NaOH) = 0,075 mol ÷ 0,165 L.
c₂(NaOH) = 0,454 mol/L.
You are correct, the atomic number is always equal to the number of protons in the element. It is the relative atomic mass that is equal to the number of protons+neutrons. Electrons have no mass
when a strong acid reacts with a strong base, the products are typically an ionic compound, which is called a salt, and the neutral molecule water.
STRONG BASE
compound that has an ablity to remove a proton from a week acid or completely dissociate as ion when in water.
<h3>STRONG ACID</h3>
A strong acid is that ionizes completely in solution. it gives greatest number of hydrogen ion or proton
<h3>IONIC COMPOUND</h3>
contains ion that are held together by the attractive force among oppositely charged ion.
<h3>SALT</h3>
substance produced by the reaction of an acid and a base
