Answer:
Answer is: A. Vinegar and soda.
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda or some other base) react quantitatively with each other.
Balanced chemical reaction of vinegar and soda:
CH₃COOH(aq) + Na⁺(aq) → CH₃COONa(aq) + H⁺(aq).
Sodium acetate (CH₃COONa) is a salt.
Answer:
c. 1.4 x 10²³ oxygen atoms
Explanation:
The number of oxygen atoms in one molecule of CH₃COOH is 2.
Avogadro's constant relates the number of molecules in one mole:
6.022 × 10²³ mol⁻¹
Thus, the number of oxygen atoms in one molecule of acetic acid can be converted to the number of oxygen atoms in one mole of acetic acid:
(2 oxygen atoms / molecule)(6.022 × 10²³ molecule / mol) = 1.204 x 10²⁴ atoms per mole
Finally, the number of oxygen atoms in 0.12 moles of acetic acid are calculated:
(1.204 x 10²⁴ atoms / mol)(0.12 mol) = 1.4 x 10²³ atoms/mol
Answer:
-1.5 N because 1.5 N would be upwards and -1.5 N would be downwards
Answer:
A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations
