Draw .. the structural formula ( using c and h ) for 2- pentyne

Answers

Answer 1

Answer:

Answer : The structural formula of 2-pentyne is shown below.

Explanation :

Structural formula : In the structural formula, the bonding and type of bonds which holds the atoms in molecule together are shown.

The given name of compound is, 2-pentyne.

A suffix '-yne' present at the end of the name represent the alkyne group.

For the number of carbon atom, we use prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.

In this compound, the parent chain is 5 membered and a triple bond is present at 2nd position of the parent chain.

Thus, the structural formula of 2-pentyne is shown below.

Answer 2

Answer: answer is below.........

10 m/s²

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = (f)/(m) \n$

f is the force

m is the mass

From the question we have

$a = (120)/(12) \n$

We have the final answer as

10 m/s²

Hope this helps you

Which layer of the Basement Membrane of epithelial tissues is produced and secreted by cells of the underlying connective tissue? (a) Reticular Lamina (b) Lamellar Lamina (c) Papillary Lamina (d) Basal Lamina

Answers

(a) Reticular Lamina

The layer of the basement membrane of epithelial tissues that is produced and secreted by cells of the underlying connective tissue is (a) Reticular Lamina.

The basement membrane is composed of two layers: the basal lamina, which is produced by the epithelial cells themselves, and the reticular lamina, which is produced and secreted by cells of the underlying connective tissue. These two layers together provide structural support and help anchor the epithelial tissue to the underlying connective tissue.

What is the mass of 4.23×10^23 atoms of iron

Answers

First divide atoms by Avogadro's number:
(4.32x10^23)/(6.02x10^23) = .703mol Fe

Then multiply moles by its molar mass:
(0.703mol Fe)(55.85g/mol Fe) = 39.24g Fe

The answer is the first option, ∆G is positive. Endergonic reaction is a chemical reaction where the Gibbs free of energy is positive and there is abosrption of energy. It is a nonspontaneous reaction or unfavorable reaction.

___wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.a. solid
b. hazardous
c. domestic

Answers

Answer: Option (b) is the correct answer.

Explanation:

When a substance is used and thrown away which can lead to damage in the environment as it may [produce some toxic or hazardous gases is known as a hazardous waste.

These wastes can be solid, liquid or gaseous.

For example, batteries, kerosene, garden chemicals etc are all hazardous waste.

A domestic waste is a waste thrown by a household which may include paper, vegetable waste, cardboard, yard clippings etc.

Thus, we can conclude that hazardous wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.

It's hazardous m8. :P
