pH = pKa + log [NaAc]/[HAc]

4.140 = 4.74 + log x

log x = -0.60

x = [NaAc]/[HAc] = 0.25

moles HAc = 1.50 L x 0.287 mol/L = 0.431 moles

Answer:

electrical forces between particles, as given by coulombs law.

Explanation:

Properties of a substance such as vapor pressure and surface tension depend on electrical forces between particles, as given by Coulomb's law.

The vapor pressure refers to how easily a liquid converts to gas while surface tension is the force that makes a liquid surface act as a stretched elastic skin.

Both vapor pressure and surface tension has a lot to do with the degree of polarity in a molecule. Usually, polar molecules have a low vapor pressure and high surface tension due to a high electrical forces between particles, as given by Coulomb's law.

n energy-carrying molecule found in all living things' cells. ATP absorbs chemical energy from the breakdown of food molecules and uses it to power other cellular processes.

Explanation:

Hope it helps

ATP is a crucial energy molecule in cells, providing energy for various cellular processes.

ATP, or adenosine triphosphate, is often referred to as the "energy currency" of the cell. It plays a vital role in cellular metabolism by providing energy for various processes. ATP is composed of adenosine and three phosphate groups. The energy stored in ATP is released when the terminal phosphate group is hydrolyzed, forming ADP (adenosine diphosphate) and inorganic phosphate (Pi).

The role of ATP in a cell is multifaceted. Firstly, ATP powers cellular work by providing the energy needed for chemical reactions, such as biosynthesis, active transport, and muscle contraction. It acts as an immediate source of energy that can be rapidly used by the cell.

Secondly, ATP participates in signal transduction and cellular communication. It can be hydrolyzed to ADP and Pi, releasing energy that can activate signaling molecules and enzymes involved in cell signaling pathways.

Furthermore, ATP is involved in maintaining cell homeostasis. It provides energy for processes like ion pumps that maintain the electrochemical gradients across the cell membrane, allowing cells to regulate their internal environment.

Overall, ATP is crucial for the functioning of cells as it serves as an energy carrier, facilitating energy transfer and powering various cellular processes essential for growth, metabolism, and cell survival.

ANTI MEANS AGAINST

Explanation:

Answer:

Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.

Answer:In a metal, atoms readily lose electrons to form positive ions (cations). These ions are surrounded by delocalized electrons, which are responsible for conductivity.

Explanation:

Due to the structure of ionic compounds, in a crystal of an ionic compound, each cation is surrounded by a number of oppositely-charged anions.

Ionic compounds are compounds that are composed of oppositely charged ions held together by strong electrostatic forces of attraction.

The ions present in an ionic compound are the positively-charged ions known as cations and the negatively-charged ions known as anions.

Each of the oppositely-charged ions are attracted to each other.

Therefore, in a crystal of an ionic compound, each cation is surrounded by a number of oppositely-charged anions.

Answer:

Number of protons is 9

Number of electrons is 9

Number of neutrons is 10

Explanation:

Atomic number refers to the number of protons or electrons in an atom, so the electrons and protons are 9.

Atomic mass is the sum of the number of protons and neutrons.

Therefore, there are 10 neutrons in the atom's nucleus

Explanation:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Accuracy of a measured value refers to how close a measurement is to the correct value. The uncertainty in a measurement is an estimate of the amount by which the measurement result may differ from this value. Precision of measured values refers to how close the agreement is between repeated measurements.

Explanation:

Sodium chloride has the highest melting point while iodine has the least melting point.

The melting points of solid substances depends on the nature of intermolecular forces that exists in the substance. The stronger the magnitude of intermolecular forces in a substance, the higher its melting point.

The order of melting points of the solids shown in question is as follows;

Sodium chloride has the highest melting points because it is an ionic substance. Among the molecular sucrose and paraffin, sucrose has a higher melting point than sucrose because it has a greater molar mass. Iodine, a molecular substance has the least molar mass and the least melting point in the list.

Answer:

A

Explanation:

The substance is a gas because the particles far randomly arranged and far apart from each other. This happens because when a substance is a gas, particles have weak attraction to each but a lot more kinetic energy which means the they move around all the time spreading out to fill the container. If it was a solid, then all the particles would be very close together and have a fixed position and if it was a liquid then the particles would be fairly close and moving around each other but as we can see in the diagram, all the particles are far apart confirming that it is a gas.

Silver or Ag is the transition element present in period 5 of the periodic table.

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.
