The correct answer is B. There are about 1,000 elements found in nature.

Explanation:

In chemistry, an element refers to a substance that contains the same kind of atoms, especially in terms of the number of protons. Examples of elements include substances like hydrogen, nitrogen, sodium, zinc, among others. Additionally, to 2019 scientists have identified around 118 elements that include both elements naturally formed and some that were created in laboratories such as the meitnerium that was created in 1982. According to this, it is false there are about 1000 elements because for now there are only 118.

HCHO2 + NaOH = NaCHO2 + H2O complete ionic
Llana [10]

Answer:

HCHO₂(aq) + Na⁺(aq) + OH⁻(aq) ⟶ Na⁺(aq) + CHO₂⁻(aq) + H₂O(ℓ)  

Explanation:

An ionic equation uses the symbols (aq) [aqueous] to indicate molecules and ions that are soluble in water, (s) [solid] to indicate insoluble solids, and (ℓ) to indicate substances (usually water) in the liquid state.

In this reaction, aqueous sodium hydroxide reacts with aqueous formic acid to form sodium formate and water.

1. Molecular equation

HCHO₂(aq) + NaOH(aq) ⟶ NaCHO₂(aq) + H₂O(ℓ)  

2. Ionic equation

Sodium hydroxide and sodium formate are soluble ionic compounds, so we write them as hydrated ions.

HCHO₂(aq) + Na⁺(aq) + OH⁻(aq) ⟶ Na⁺(aq) + CHO₂⁻(aq) + H₂O(ℓ)
