Answer:

Liquid has the following properties -

- Liquids are almost incompressible due to the fact that molecules do not have a lot of space between them so they can not be compressed.

- Liquids have a fixed volume but shape varies according to the container it is placed in. It changes the shape even the volume is the same.

- Liquids flow from higher to lower levels.

- Liquids have their boiling points above room temperature, under normal conditions.

Measure the volume of a liquid sample-

The volume of the liquid can find out by dividing the mass of the liquid by the density of the liquid. D = m/v. The density of water is 1 gram/cubic centimeter.

Now, the problem provides you with a mass of ethane,

, and asks for the volume of carbon dioxide,

, formed by the reaction at STP, Standard Temperature and Pressure.

As you know, STP conditions are defined as a temperature of

0

∘

C

and a pressure of

100 kPa

. Under these specific conditions, one mole of any ideal gas occupies exactly

22.7 L

- this is known as the molar volume of a gas at STP.

So, what this means is that if you know how many moles of carbon dioxide are produced by the reaction, you can use the molar volume of the gas to find the requested volume.

Use the molar mass of ethane to determine how many moles you'd get in that

Now, notice that you have a

mole ratio between ethane and carbon dioxide. Since ethane reacts with excess oxygen, you can assume that all the moles will take part in the reaction.

This means that the reaction will produce

The answer is rounded to four sig figs, the number of sig figs you have for the mass of ethane.

Explanation:

Answer: Enthalpy is the heat content of a system. The enthalpy change of a reaction is equivalent to the amount of energy lost or gained during the reaction. A reaction is favoured if the enthalpy of the system decreases over the reaction. Entropy refers to the measure of the level of disorder in a thermodynamic system.

Answer: D

Explanation: Metals are solid at room temp and also are shiny and can be flattened or broken into pieces when hammered and some metals are high and low conductors of electricity.

Metals have a characteristic property of conduction and malleability  and thus  sample 1 is metallic.

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

chromosomes is responsible

The reproduction is defined as a process which involves the production of offspring. The genetic instructions are stored in chromosome. The correct option is C.

A chromosome is defined as the DNA molecule which consists of all the genetic material of an organism. It is found to be present in the nucleus of each cell. The DNA inside the chromosome is tightly coiled around special proteins called histones.

All living organisms are composed of chromosomes. Humans have 23 pairs of chromosomes. 22 pairs of these chromosomes are called autosomes. These are same in both males and females. The 23rd pair of chromosomes are called allosomes and they differ between sexes.

The males have one 'X' and 'Y' chromosome, while females have two copies of the 'X' chromosome. The important function of genetic material is to store information needed by the cell to make proteins.

Thus the correct option is C.

The result of the atomic theory was that chemists began to better understand the properties of matter. Therefore, option (D) is correct.

The atomic theory, proposed by John Dalton in the early 19th century, postulated that matter is composed of indivisible particles called atoms. This theory revolutionized the field of chemistry by providing a framework to understand the behavior and interactions of different substances.

By recognizing that matter is composed of discrete atoms with specific properties, chemists were able to explain phenomena such as chemical reactions, the conservation of mass, and the formation of compounds. The atomic theory laid the foundation for modern chemistry, leading to advancements in understanding the structure of atoms, the development of the periodic table, and the ability to manipulate and engineer materials at the atomic level.
