Which of the following statements about nonmetal elements is true?


A.) Nonmetal elements are stronger than metals.

B.) Nonmetal elements are never used in computers.

C.) Nonmetal elements are sometimes cheaper to make.

D.) Nonmetal elements are used only in laptop computers.

Answers

Answer 1

Answer:

C

Explanation:

Answer 2

The statement which is true about non-metal elements is as follows:

Nonmetal elements are sometimes cheaper to make.

Thus, the correct option for this question is C.

What are Non-metals?

Non-metals may be defined as those chemical elements that significantly lack the attributes of metals. They generally range from colorless gases to shiny and high melting point solids. Some examples of non-metals include boron, carbon, nitrogen, etc.

Non-metals are not stronger than metals because the arrangement of bonds in metals is highly compacted. Non-metals are very frequently utilized in the manufacture of computers, laptops, and other electronic devices along with metals. But most of the time non-metals are cheaper to synthesize.

Therefore, non-metal elements are sometimes cheaper to make is a statement that is true about non-metal elements. Thus, the correct option for this question is C.

Both covalent-network solids and ionic solids can have melting points well in excess of room temperature, and both can be poor conductors of electricity in their pure form. However, in other ways their properties are quite different. a. Which type of solid is more likely to dissolve in water

Answers

Answer:

IonicEvidence: It can be proved by a simple experiment, sand doesn't dissolve in water but NaCl (table salt) does. (excluding cases like BaSO4 and sugar and amino acids)

Cause: The electrostatic bonds among ions in a lattice only hold them together like two magnets with unlike poles facing each other. The water molecules can split them through the similar process with several molecules ganging up on them, the H+ parts of the molecules attracts the anion and O2- part; the cations. If this electrostatic attraction is big enough, the bonds between the solid's ions break (into separate ions). And so the solid dissolves. This is usually the case with most.

Why not covalent structures?: Sure, covalent solids have a low m.p and b.p for low intermolecular forces, the covalent bonds here are strong and cannot easily be 'pulled apart' by water molecules. They usually have stronger intermolecular forces than that of water.

But... if their intermolecular forces are weaker or similar, sure they can dissolve easily. Like any often-used alcohol (glacial).

The volume of a sample gas is 650.ML at 0.00C. What volume will the sample occupy at 75C?

Answers

Answer: 828.57mL

Explanation:

First and foremost, we need to convert the degree in Celcius to Kelvin, this will be C + 273 = K

Temperature 1 = 0 + 273 = 273K.

Temperature 2 = 75 + 273 = 348K.

We then plug the values gotten into.the formula which will give:

650/273 = x/348

X = (650 × 348) / 273

X = 828.57mL

The volume that the sample will occupy at 75C would be 828.57mL.

Consider the above reaction. If some CO2 were removed from the container, what would the reaction do in an attempt to replace the CO2?

Answers

Answer:

See explanation

Explanation:

The reaction to be considered is shown below;

H2CO3<------->CO2 + H2O

We know  that when a constraint such as a sudden change in concentration, pressure or temperature is imposed on  a reaction system in equilibrium, the system has to adjust itself by shifting in a particular direction in order to cancel the constraint.

Now, if we remove CO2, the equilibrium position must shift to the right by the decomposition of more H2CO3 to establish equilibrium again.

Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.

Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.

Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.

Purpose

The purpose of genes is to store information.

Each gene contains the information required to build specific proteins needed in an organism.

Answers

Data Given:
Moles = n = 3.91 mol

Pressure = P = 5.35 atm

Temperature = T = 323 K

Volume = V = ?

Formula used: Ideal Gas Equation is used,

P V = n R T
Solving for V,
V = n R T / P
Putting Values,
V = (3.91 mol × 0.0825 atm.L.mol⁻¹.K⁻¹ × 323 K) ÷ 5.35 atm

V = 19.36 L

How many formula units are in 4.56 moles of LiCl?

Answers

Answer:

In 4.56 moles of LiCl 27.46*10^23 formula units is present.    

Explanation:

Formula units is defined as the empirical formula for any ionic, covalent and  network solid compounds which are used as a single unit for stoichiometric calculations. Also It can be defined as the lowest whole number ratio of ions which can be represented in an ionic compound.

We are given

4.65 moles of Lithium chloride.

One mole of Lithium chloride has 6.022*10^23 unit  Formula unit

In 4.56 moles of Lithium Chloride the formula unit will be

              = 4.56*6.022*10^23

Formula units    = 27.46 * 10^23

It is clear that in 4.56 moles of Lithium Chloride will contain 27.46*10^23 Formula unit.

Therefore in 4.56 moles of LiCl 27.46*10^23 formula units is present.
