# To completely neutralize a 0.325 g sample of pure aspirin, 15.50 mL of a sodium hydroxide solution is added. If 16.25 mL of the same sodium hydroxide solution must be added to an aspirin tablet sample during a titration to reach the endpoint, calculate the mass of aspirin in the tableA. 0.310 g B. 0.288 g C. 0.392 g D. 0.450 g E. 0.341 g

Answer: The correct option is E.

Explanation: The reaction between aspirin (also known as acetylsalicylic acid) and sodium hydroxide is known as acid-base titration reaction.

By applying Unitary method, we get:

15.50mL of NaOH dissolves = 0.325 g of aspirin

So, 16.25 mL of NaOH will dissolve = = 0.341 g

Hence, the correct option is E.

It is possible for gases in the atmosphere to change the behavior of energy on earth. Agree or disagree

The green house gases in the atmosphere can change the behavior of energy on earth. Thus i agree with this statement.

### What is green house effect?

The green house effect is defined as a process by which the radiations from the sun are absorbed by the green house gases like methane, Chloro fluoro carbons and not reflected back into the space. This makes the surface as insulator and prevents it from freezing.

Due to the increased level of green house gases, the temperature of the earth increases considerably and thereby causes global warming, depletion of ozone layer, smog and air pollution, etc.

It is the natural green house effect which affect the behaviour of heat energy radiated by the sun. The green house gases never let the radiations escape from the earth and increase the surface temperature of earth. This leads to global warming.

Thus green house gases affects the solar energy.

I agree

Explanation:

because the sunlight passes through the atmosphere and is absorbed by earth's surface.

At this location, it is summer in the Northern Hemisphere because the North Pole is tiltedAway from the sun

Towards the sun

This happens twice a year during Earth's orbit. Near June 21 the north pole is tilted 23.5 degrees toward our Sun and the northern hemisphere experiences summer solstice, the longest day of the northern hemisphere year.

points toward the sun.

closer the earth is to the sun the more  hot it will be the closer it is to summer,

you can see at D northern hemisphere is closest to sun and the north pole is pointing toward the sun.

Identify the type of bonding within each substance. Co ( s ) ionic covalent metallic CoCl 2 ( s ) covalent ionic metallic CCl 4 ( l ) metallic covalent ionic

1. Co ( s ) - metallic bonding

2. CoCl₂ ( s ) - ionic bonding

3. CCl₄ ( l ) - covalent bonding

Explanation:

Metallic bonding -

It is the type of bonding present between the atoms of the metals , via the electrostatic interaction between the metal and the delocalized electrons , is known as metallic bonding .

For example ,

Mostly metals show metallic bonding .

Ionic bonding -

It is the type of bonding present between the ions i.e. , the cation and the anion is known as ionic bonding .

For example ,

Mostly ionic compound , like salts show ionic bonding .

Covalent bonding -

It is the type of bonding which is present between shared pair of electrons , is known as covalent bonding .

For example ,

Most of the carbon compounds are capable to show covalent bonding .

Hence , from the question ,

1. Co ( s ) - metallic bonding

2. CoCl₂ ( s ) - ionic bonding

3. CCl₄ ( l ) - covalent bonding

Co(s) forms metallic bonds, CoCl2(s) forms ionic bonds, and CCl4(l) forms covalent bonds.

### Explanation:

The type of bonding within each substance can be identified by understanding the nature of the substances.

1. Co(s): Co (solid) denotes a metal, and metals typically form metallic bonds.
2. CoCl2(s): CoCl2 is a compound formed between a metal (Co) and a nonmetal (Cl), making it an ionic compound.
3. CCl4(l): CCl4 is a molecular compound composed of carbon and chlorine atoms, so it forms covalent bonds.
