Draw and name the structures of the carboxylic acids and esters you put together using molecular models.

Neporo4naja [7]

Answer:

This question is incomplete

Explanation:

However, when the carboxylic acids and esters put together are obtained, the procedure below can be followed in drawing and naming them.

For carboxylic acid,

1) it should be noted that the functional group here is -COOH which is drawn as -C = OH

2) The carbon of the functional group is included among the carbon to be counted when naming the structure. For example, the compound below is propanoic acid.

CH₃CH₂COOH - As you can see that there are 3 carbons linked chain there.

3) As can be seen in (2) above, the suffix "oic" is used to name carboxylic acids

4) The carbon chain here is saturated (meaning there is no double or triple bond within the carbon chain)

Example of a structure of carboxylic acid is

H₃C - CH₂ - CH₂ - C = OH

The structure above is a butanoic acid

For ester

1)The functional group here is -COO- . which can be drawn as

- C = O

O -

(meaning one oxygen atom is double bonded to the carbon and the other oxygen atom is bonded to another carbon chain)

2) The alkyl group attached to the oxygen atom is first of all mentioned before the carbon chain attached from the left is mentioned. For example, CH₃CH₂CH₂COOCH₂CH₃ is ethyl butanoate

3) As seen from (2) above, the suffix "oate" is used to end the name of esters

4) As also seen from (2) above, the carbon of the functional group is also included while counting the carbon chain of the parent name (butanoate).

5) The carbon chains here are also saturated.

Example of this ester is

CH₃CH₂C = O

O - CH₂CH₃

The name of this compound is ethyl propanoate

Agents that antagonize the effects of acetylcholine are called __________.

fenix001 [56]

Agents that antagonize the effects of acetylcholine are called anticholinergic.
Anticholinergic blocks this neurotransmitter acetylcholine within the nervous system, by deactivating nerve impulses as a result of the binding of this neurotransmitter so that it cannot reach its receptor in nerve cells.

Which will reduce the possible environmental damage associated with mining uranium?

blagie [28]

We need to discuss about reduction of possible environmental damage associated with uranium mining.

There are several extraction processes involved in mining uranium as- (i) surface mining, (ii) heap leaching, (iii) underground mining and so on.

There are so many risks involved towards environment and health.

There are some improvements for long term stabilization of Uranium mining have been documented. They are as follows-back-filling and using residues for the construction of motorways, washing of soil with water, carbon treatment inclusion of new materials like room temperature ceramics for the immobilization of various contaminants, de-watering, and land encapsulation.

A gas occupies 525 mL at a pressure of 45.0 kPa. What would the volume of the gas be at a pressure of 65.0 kPa

choli [55]

Answer:

The volume of the gas at a pressure of 65.0 kPa would be 363 mL

Explanation:

Boyle's Law is a gas law that relates the pressure and volume of a certain amount of gas, without temperature variation, that is, at constant temperature.

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. In other words, the product P · V remains constant at the same temperature:

P*V=k

Being P1 and V1 the pressure and volume in state 1 and P2 and V2 the pressure and volume in state 2 are fulfilled:

P1*V1=P2*V2

In this case:

P1= 45 kPa= 45,000 Pa (being 1 kPa=1,000 Pa)
V1= 525 mL= 0.525 L (being 1 L=1,000 mL)
P2= 65 kPa= 65,000 Pa
V2= ?

Replacing:

45,000 Pa* 0.525 L= 65,000 Pa*V2

Solving:

$V2=\frac{45,000 Pa* 0.525 L}{65,000 Pa}$

V2=0.363 L=363 mL

The volume of the gas at a pressure of 65.0 kPa would be 363 mL
