Where are the electrons most probably located in a molecular bonding orbital?

1 answer:

8 0

In covalent molecular bonding, the electrons that are involved in bonding are shared by the two bonding atoms. This means the electrons are probably located between the two nuclei of the atoms. This is represented diagrammatically by drawing orbitals between the two nuclei. <span />

HELP

Natalka [10]

Explanation:

To find the amount of product that would be formed from two or more reactants, we need to follow the following steps;

Find the number of moles of the given reactants.
Then proceed to determine the limiting reactant. The limiting reactant is the one in short supply which determines the extent of the reaction.
Use the number of moles of the limiting reactant to find the number of moles of the product.
Then use this number of moles to find the mass of the product

Useful expression:

Mass = number of moles x molar mass

The plants characteristic green color comes from the chemical

frosja888 [35]

Answer:

chlorophyll

Explanation:

Plants are green because their cells contain chloroplast which have pigment which absorb deep-blue and red light so that the rest of the sunlight spectrum is being reflected, causing the plants to look green.

A student has a mixture of salt (NaCl) and sugar (C12H22O11). To determine the percentage, the student measures out 5.84 grams o

julsineya [31]

Answer:

The volume of 1.0 AgNO₃ that would be required to precipitate 5.84 grams of NaCl is 99.93 ml

Explanation:

Here we have the reaction of AgNO₃ and NaCl as follows;

AgNO₃(aq) + NaCl(aq)→ AgCl(s) + NaNO₃(aq)

Therefore, one mole of silver nitrate, AgNO₃, reacts with one mole of sodium chloride, NaCl, to produce one mole of silver choride, AgCl, and one mole of sodium nitrate, NaNO₃,

Therefore, since 5.84 grams of NaCl which is 58.44 g/mol, contains

$Number \, of \, moles, n = \frac{Mass}{Molar \ mass} = \frac{5.84}{58.44} = 0.09993 \ moles \ of \ NaCl$

0.09993 moles of NaCl will react with 0.09993 moles of AgNO₃

Also, as 1.0 M solution of AgNO₃ contains 1 mole per 1 liter or 1000 mL, therefore, the volume of AgNO₃ that will contain 0.09993 moles is given as follows;

0.09993 × 1 Liter/mole= 0.09993 L = 99.93 mL

Therefore, the volume of 1.0 AgNO₃ that would be required to precipitate 5.84 grams of NaCl is 99.93 ml.

Can someone help me pls will mark Brainly and 10+ points

Answer:

Hope this helps :)

Explanation:

1. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.

2. Matter is everything around you. Atoms and compounds are all made of very small parts of matter.

3. Solid, liquid and, gas

4. False

5. Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon.

6. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
