Part A.4 and Part B. In a hurry to complete the experiment, Anna withdrew two volumes of solution from Part A.2 before the preci

pitate had settled. As a result, what dilemma might she have encountered in Part B
Chemistry

Harman [31]2 years ago
6 0

Answer:

Anna may have trouble because of inaccurate results or observations.

<u>Explanation:</u>

In chemistry, a precipitate is an <em>insoluble solid</em> that is gotten from a liquid solution. Because Anna withdrew two volumes of solution from Part A.2 before the precipitate had settled she may find it difficult to determine the limiting reactant; that is the chemical element or substance that limits the amount of product made during the chemical reaction because some precipitate was captured with the liquid lying above, which when adding the reagent, will not show the difference between them.

etermine the number of valence electrons for each of the atoms. Enter each answer as a numeral. For example, if an atom has two
Sav [38]

Answer:

1. 1

2. 2

3. 6

4. 8

Explanation:

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

1. Li is the symbol for the chemical element known as Lithium: it has 1 valence electron. The electronic configuration of lithium is 1s²2s¹

2. Mg is the symbol for the chemical element known as Magnesium: it has 2 valence electrons. The electronic configuration of magnesium is 1s²2s²2p63s²

3. O is the symbol for the chemical element known as Oxygen: it has 6 valence electrons. The electronic configuration of magnesium is 1s²2s²2p⁴.

4. Ne is the symbol for the chemical element known as Neon: it has 8 valence electrons.

Predict the aldol product when the following ketone undergoes self-condensation in the presence of NaOH. Do not show the dehydra
Anit [1.1K]

Answer:

β-hydroxyaldehyde (an aldol) namely 3-Hydroxy butanal.

Explanation:

When acetaldehyde is treated with dil.NaOH it undergoes self condensation as it contains alpha-hydrogen atom in its compound forming β-hydroxyaldehyde (an aldol) namely 3-Hydroxy butanal. This compound upon further heating will eliminate a molecule of water forming aldol condensation product namely Crotonaldehyde Or But-2-en-al. see the diagram attached.

9. How many protons, neutrons, and electrons does 35C1l- have?
Alekssandra [29.7K]
It’s the third one because Cl has 17 protons bc of the numeric number and 18 electrons bc it’s always the opposite and 18 neutrons because you subtract 35-17=18
