Abiotic factors, also called abiotic components, are non-living parts of the environment which affects the living organisms and their function in the ecosystem. I think the correct answer is A. Wind factor is the only non-living part from the choices.

The bond polarities of a molecule of ammonia (NH₃) are <u>polar</u>.
The molecular shape of a molecule of ammonia (NH₃) is <u>trigonal pyramidal</u>.
The molecule of a molecule of ammonia (NH₃) is <u>polar</u>.

<h3>The types of covalent bond.</h3>

In Chemistry, there are two (2) main types of covalent bond and these include the following:

Polar covalent bond.

Non-polar covalent bond.

<h3>What is electronegativity?</h3>

Electronegativity can be defined as the ability or tendency of the atom of an chemical element to attract any shared pair of electrons.

In Chemistry, the difference in electronegativity between an atom of nitrogen (N) and hydrogen (H) causes electrons to preferentially orbit an atom of nitrogen (N), thereby, making the bond polar.

Furthermore, the molecular shape of a molecule of ammonia (NH₃) is <u>trigonal pyramidal</u> and the molecule of a molecule of ammonia (NH₃) is <u>polar</u>.

Define symbol and compound with an exomple.

vazorg [7]

Symbol: A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. For example, a red octagon is a common symbol for "STOP"; on maps, blue lines often represent rivers; and a red rose often symbolizes love and compassion.

Compound: a thing that is composed of two or more separate elements; a mixture.
For Example: water (H2O), salt (sodium chloride, NaCl), methane (CH4).

what volume (in ml) of 1.508 m h3po4 (aq) would be required to react completely with 11.73 ml of 1.006 m ca(oh)2? (aq)

alexdok [17]

The amount of 4.86 ml needed to completely react with 11.73 ml of 1.006 m ca(oh)2 is 4.86 ml.

given data to be calculated:-

Ca3(PO4)2 (s) + 6H2O can be used to calculate this: 3Ca(OH)2 (aq) + 2H3PO4 (aq) (l)

ca moles (OH)

2 present 11.00 moles of H3PO4 are required; 7.33 moles of H3PO4 in a volume of ml are required; 7.33/1.508 = 4.86.

<h3>How do moles react to an increase in volume?</h3>

The direction that creates more moles of gas benefits from an increase in volume, and since there are more moles of products in this case, the reaction will shift to the right and produce more moles of products.

calculate the volume of hydrogen gas that is produced by the reaction of 0.52 grams of solid magnesium with excess hydrochloride

joja [24]

Answer:

0.493L

Explanation:

Let us write a balanced equation for the reaction. This is illustrated below:

Mg + 2HCl —> MgCl2 + H2

Next, let us convert 0.52g of Mg to mole. This is illustrated below:

Molar Mass of Mg = 24g/mol

Mass of Mg = 0.52g

Number of mole of Mg = Mass /Molar Mass = 0.52/24 = 0.022mole

From the equation,

1mole of Mg produced 1mole of H2.

Therefore, 0.022mole of Mg will always produce 0.022mole of H2.

1mole of H2 occupies 22.4L at stp.

Therefore, 0.022mole of H2 will occupy = 0.022 x 22.4 = 0.493L
