What type of organic compound has the empirical formula CH2O and can serve as energy storage or the starting material for fats a
Luda [366]
Carbohydrates. CH2O is the most basic formula of simple sugars.Empirical formula is the lowest whole number ratio of atoms in a formula.For example glucose is C6H12O6 can be reduced by 6 to get CH2O. Simples sugars include glucose and fructose which can serve as sources of energy for fats and amino acids.

During prophase, which of the following events
alexdok [17]

Answer:

Spindle fibers form.

DNA condenses into chromosomes.

Explanation:

Prophase is the first stage of mitosis. Mitosis produces 2 daughter cells from a parental cell.

Spindle fibers form - this is true. During prophase, the mitotic spindle forms. Later during mitosis the spindle attaches to the centromere of chromosomes and pulls them to opposite ends of the cell prior to division

DNA condenses into chromosomes.  - this is true. In the nucleus during interphase, the DNA is relatively loosely compacted. However, prior to division, the DNA is condensed into structures called chromosomes which are then paired up and distributed to the daughter cell.

Chromosomes move to opposite ends of the  cell.  - this is false. This happens during anaphase

Nuclear membrane begins to re-form. - this is false. This happens during telophase.

When aqueous solutions of AgNO 3 and KI are mixed, AgI precipitates. The balanced net ionic equation is ________. Ag (aq) I- (aq
dimulka [17.4K]

Answer:

Ag⁺(aq) + Cl⁻(aq) ==> AgCl(s)

Explanation:

The net ionic equation can be described as the equation that contains only those species which would be participated in the chemical reaction. The spectator ions are the type of the ions that are present in both sides of the chemical equation these ions could not be present in the net ionic equation

First, it is easiest if you write the compete molecular equation:

AgNO₃(aq) + KCl(aq) ⇔ AgCl(s) + KNO₃(aq)

we look up which compounds are soluble (aq) and which are not (s). In this case, silver chloride (AgCl) is not soluble.  Thus, the net ionic equation is...  

Ag⁺(aq) + Cl⁻(aq) ==> AgCl(s)
