In the notations C-12 and C-14, what do the numbers after the element
symbol and hyphen represent?

Answer:

Variable costs are costs that change depending on the amount of the product you are providing. Fixed costs On the other hand are costs that are the same no matter how much of the product or service you are providing. Fixed costs are also called overhead or fixed operating costs.

Answer:  In a perfectly isolated system, the total energy is the same.

Explanation:  The conservation laws for mass and energy hold in a system that is isolated from its surroundings.  The enegy released by the dissolution of solid NaOH in water is absorbed by the water.  So the total energy of the syetm remains the same.  It is simply converted from lattice energy of the NaOH into heat energy as measured by the temperature of the water.  As long as it is operfectly isolated, the total energy remains the same.

The answer is:

Because they have 1 more or less electron in there last orbit, so they are very active to form compounds which make them stable.

Explanation:

The chemical formula of aluminium carbonate is written as Al2(CO3)3.

The chemical formula of a compound is a representation of the atoms that compose the compound. Usually, the chemical formula is derived from the name of the compound.

We know that the carbonate ion is CO3^2- while the aluminium ion is Al^3+. It follows that the compound, aluminium carbonate ought to have the formula, Al2(CO3)3. The compound aluminum oxide has the formula Al2O3 while the compound aluminum bicarbonate has the formula Al(HCO3)3.

Answer:

Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room, but at a much slower rate. Heat transfer by convection also occurs through cold air entering the room around windows and hot air leaving the room by rising up the chimney.

When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. ... A space heater is a classic convection example.

Explanation:

The nomenclature of ionic compounds is given by:

1. Positive is written first.  And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

1.)  : Calcium chloride  (Correct)

In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.

2.)  : Copper (II) oxide   (Incorrect)

In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.

3.)  : Lead (II) sulfide   (Incorrect)

In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.

luminous is relating to light as it is perceived by the eye, rather than in terms of its actual energy.

A brief description explaining the term "luminous" to generating or reflecting brilliant light, particularly at night: luminous attire. The bright glow of laptops illuminated the library.

Luminous objects are things like the sun that produce or radiate light on their own. Others include a torch, an electric lamp, etc. Non-bright objects are those that don't emit any light of their own and can only be seen when light from a luminous source reflects off of them. Moon, a chair, a painting, etc. are a few examples.

Luminous objects are defined as those that produce their own light. Just the sun emits its own light; all other things only reflect light that is incident upon them.

The presence of luminous items produces the feeling of light. These things are visible because they independently emit light. As an illustration, consider the Sun, the stars, lightbulbs, torches, tube lights, candles, and so on.

Thus,the term "luminous" to generating or reflecting brilliant light, particularly at night: luminous attire. The bright glow of laptops illuminated the library.

Explanation:

because the chemicals or substances mix together so it's basically like chemical bonding.

In cup A, the temperature of the water will drop after 1 hour and the temperature of the aluminium will rise. In cup B, there will be no change in temperature of the water and the aluminium. The type of heat transfer taking is conduction.

When two bodies at different temperatures come into contact which other. Heat is transferred from the hotter body to the cooler body until thermal equilibrium is achieved between the two bodies. The temperature of the water decreases while that of the aluminium bar rises.

The aluminium bars were put into the two cups holding water at 90℃ and 20℃ respectively. Since the water in cup A is at a higher temperature than the aluminium, heat is transferred from the water to the aluminium bar until thermal equilibrium is achieved.

In cup B, there is no temperature difference between the water and aluminum hence no heat transfer occurs. Note that a mode of heat transfer that depends on temperature difference between two bodies in contact is conduction.
