Answer:

Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.

Explanation:

The molecular mass gives the mass of a molecule relative to that of the 12 C atom, which is taken to have a mass of 12. Hence why Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.

Answer:

It is an Ionic bond

Answer:

Explanation:

Find the molar mass of H2SO4

2H = 2 * 1 = 2

S  = 1 * 32 =32

O4 = 4*16 = 64

total             98

Find the number of mols in 71.5 grams

mols = given mass / molar mass.

given mass = 71.5

molar mass = 98

mols = 71.5/98

mols = 0.7296 mols of H2SO4

Find the moles of H2O

From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O

mols water = 2 * 0.7296

mols water = 1.4592

That's as far as I can take you. I have to know a great deal more to get the volume of H2O

Answer:

The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus

Gamma rays are used in medicine (radiotherapy), industry ( Sterilization and disinfection) and the nuclear industry.

Answer:

Option 2 and 4 are correct

Explanation:

The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants.

This is an addition reaction in which two reactants add up to form the product.

Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive.

Reactants have more energy than the products.

The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.

“Microorganisms are minute organisms that are invisible to the normal eye.” Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc.

Given options are-

A. adding manure or compost to the soil

B. spraying chemical weed-killers and fertilizers on the soil

C. removing all ground-covering plants from the soil

D. adding sewage containing synthetic materials to the soil

Therefore, The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

Answer:

Cell division is the process by which a cell, called the parent cell, divides into two cells, called daughter cells.[1] When the cell divides, everything inside it divides also. The nucleus and the chromosomes divide, and the mitochondria divide also.

In mitosis, an ordinary body (somatic) cell divides to make two daughter cells.

In meiosis, a cell divides twice, to produce four gametes (sex cells). The first division of meiosis is a special kind of cell division called a reduction division because the number of chromosomes is halved. The second division of meiosis is similar to mitosis.[2]

Three types of cell division: left is binary fission as in bacteria; right are mitosis and meiosis as in eukaryotes.

Cells are the 'building blocks' of life, and cell division is a basic feature of life. For simple unicellular organisms like Amoebozoa, one cell division reproduces the entire organism. On a larger scale, cell division can create offspring from multicellular organisms, such as plants that grow from cuttings. But most importantly, cell division enables organisms that are able to sexually reproduce to develop from the one-celled fertilised egg (zygote). Cell division also allows for continual renewal and repair of the organism.

The cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.

It is the process by which cells divide into daughter cells. This keeps the cell organism to survive.

Explanation:

The atmospheric pressure in West Chester, Pennsylvania is lower than the pressure on any summer day in Breckenridge, Colorado

Colorado is 1.6 kilometers above sea level while Pennsylvania is 0.33 kilometers above sea level.

The higher a place is above sea level, the higher is the air pressure.

Explanation:

Answer:

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart.

Explanation:

Answer:

81.5g/mol

Explanation:

Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.

To solve this question we must find the moles of the gas in order to obtain the molar mass using:

PV = nRT

PV / RT = n

Where P is pressure = 0.980atm

V is volume in Liters = 0.0725L

R is gas constant = 0.082atmL/molK

T is absolute temperature = 68°C + 273.15 = 341.15K

0.980atm*0.0725L / 0.082atmL/molK*341.15K = n

2.54x10⁻³ moles = n

Thus, the molar mass of the gas is:

0.207g / 2.54x10⁻³ moles

FOLLOW MY ACCOUNT PLS PLS

A buffer is primarily used to limit the pH change in a solution. Option A is correct.

A buffer is the solution which contains the weak acid and its conjugate base or weak base and its conjugate acid. It is designed to resist changes in pH when small amounts of acid or base are added to it.

When an acid or base is added to a buffer solution, the buffer components react with the added ions to minimize the impact on the solution's pH. If an acid is added, the buffer will react with the acid by accepting the H⁺ ions. If a base is added, the buffer will react with the base by donating H⁺ ions. In both cases, the buffer helps maintain the pH at a relatively stable level.

To prevent an acid from dissociating, is not accurate. A buffer does not prevent an acid from dissociating. In fact, the acid in a buffer solution is necessary to provide the conjugate base and maintain the buffer's pH buffering capacity.

To neutralize the pH of a solution, is also not accurate. A buffer does not neutralize the pH of a solution to a particular value. Instead, it resists significant changes in pH when small amounts of acid or base are added.

To prevent a salt from dissolving, is unrelated to the purpose of a buffer. A buffer is not used to prevent the dissolution of salts.

Hence, A. is the correct option.
