Answer 1

Answer:

Answer:

Milk, cream, milk solids, sugars, modifying agents and flavourings are blended together in stainless steel vats.

The mix is homogenised to create a consistent texture.

The mix is pasteurised by heating at 82-85°C for 15 seconds then cooled to destroy bacteria.

(2) The ion is negatively charged because it has more electrons than the atom.
(3) The ion is positively charged because it has fewer electrons than the atom.
(4) The ion is positively charged because it has more electrons than the atom.

Answers

The question is,'what can be concluded if the ion of an element is smaller than the atom of the same element'. The correct option is 'the ion is positively charged because it has fewer electrons than the atom. An atom becomes charged either by donation or accepting electrons. When an atom donate electrons, it becomes positively charged and it has less electrons than its atom. For instance, calcium has 20 electrons, it becomes an ion by donating its two electrovalent electrons, thereby having only 18 electrons left. But when an element accepts electrons, it becomes negatively charged and has more electrons than its atom.

The following conclusion can be made if an ion of an element is smaller than an atom of the same element:

$\boxed{\left( 3 \right){\text{ The ion is positively charged because it has fewer electrons than the atom}}{\text{.}}}$

Further explanation:

Ions are the entities with a net electric charge, be it positive or negative. Since positive and negative charges can be present on the ions, ions are of two types-positively charged and negatively charged ions. The ions formed by loss of electrons develop a positive charge and are called cations. But the ions produced by the gain of electrons acquire a negative charge and are called anions.

Since cations are positively charged ions, these have fewer electrons as compared to the corresponding neutral atom. So these ions experience stronger forces of attraction with the atomic nucleus and are smaller in size in size than the parent atom.

Anions are formed by the addition of electrons to the neutral atom. It has more electrons than the parent atom so it feels electron-electron repulsion due to which its size becomes larger than the parent atom.

So cations are smaller than the parent atom of the same element whereas anions are larger than the parent atoms. Therefore if an ion is smaller than the atom, it is positively charged due to the presence of fewer electrons than the parent atom.

He accepted value for the density of liquid mercury is 13.5336 g/mL. Four scientists measure the density of liquid mercury in their individual laboratories. The most accurate measurement is made by

Answers

Answer;

-The most accurate measurement is made by;

C. Dr. Smith, who measures 13.54 g/mL.

Explanation;

-The absolute density (how much a given volume of the substance weighs) of mercury is 13593 kilograms per cubic meter. It can also be stated as 13.56 g/cm^3. Accuracy measures the nearness of a calculation to the true value.

-In this case; the measurement by Dr. Smith is near the true value 13.56 g/cm^3, as compared to the measurements by other scientists.That is Dr. Chopra, who measures 13.487 g/mL. Dr. Thompson, who measures 13.5 g/mL. and Dr. Tyler, who measures 13.9336 g/mL.

The most accurate measurement is made by Dr. Smith. He measures this as 13.54 g/ml.

Name the two sub-atomic particles in the nucleus of an aluminium atom.

Answers

The two sub-atomic particles present in the nucleus of an aluminum (Al) atom are: proton and neutrons.

Protons: Positively charged protons are present in the atom's nucleus. They have an approximate relative mass of 1 atomic mass unit (amu), a relative charge of 1, and a relative mass of 1.

Neutrons: The nucleus of an atom contains neutrons, which are neutral particles. They have a relative mass of roughly 1 atomic mass unit (amu) and no electric charge (their charge is zero).

The number of protons in an aluminum atom determines its atomic number, which is 13, and the number of neutrons can vary, resulting in various aluminum isotopes with various masses. Aluminum-27, which has a nucleus made up of 13 protons and 14 neutrons, is the most prevalent isotope of the metal.

Answers

The correct answers are:

17. All of the above
18. hydrogen gas and oxygen gas
19. deposition of a metal layer on a material

Electrolytic cells use electric currents to drive a non-spontaneous reaction forward. This is also used in electroplating which involves the movement of metal cations to the surface of another metal. Water can also undergo electrochemical reactions by splitting it into its gaseous components, hydrogen and oxygen.

Final answer:

An electrolytic cell uses an electric current to make a nonspontaneous reaction go and is used in electroplating. The products formed in the electrolysis of water are hydrogen gas and oxygen gas. Electroplating involves the deposition of a metal layer on a material.

Explanation:

An electrolytic cell is a type of cell that uses an electric current to make a nonspontaneous reaction go. This means it can drive a chemical reaction in a direction that does not occur naturally. Electrolytic cells are commonly used in electroplating, where a metal layer is deposited onto a material. Therefore, all of the given options in question 17 are true about an electrolytic cell. For question 18, the products formed in the net reaction of the electrolysis of water are hydrogen gas and oxygen gas. Electrolysis of water involves the decomposition of water into its elemental components. In electroplating, the process involves the deposition of a metal layer on a material. This is achieved by passing an electric current through a solution containing metal ions, causing the metal ions to be reduced and deposit onto the material's surface.

For the reaction below, describe the temperature and pressure conditions that would produce the highest yield of the forward reaction. Explain your answer in terms of Le Châtelier's principle.

Answers

The correct answer for the question that is being presented above is this one: "CO(g) + 2H2 (g) <---> CH3OH (g) and that the reaction is exothermic (the delta H value is negative). The reaction is exothermic, so lowering the temperature will shift the equilibrium toward the right. Since the reaction uses 3 moles of gas to form 1 mole of gas, increasing the pressure will shift the reaction toward the right. So, low temperature and high pressure will produce the highest yield. Le Chatelier's principle states that when a system at equilibrium is disturbed, the system responds in such a way to minimize the disturbance."
