If you have 460 grams of H2o, how many molecules are present?

Answers

The answer is 1.537×10^25 molecules.

This question requires the use of avogadro’s number, which represents the number of formula units (could be atoms or molecules) in a mole. Avogadro’s number is 6.02214076×10^23 per mole. The first step is to determine how many moles of water is 460 grams of H2O. The molar mass of H2O is 18.02 grams per mole, and by dividing 460 grams of H2O by 18.02 grams per mole, you find that there’s are 25.53 moles of H2O present. We know from Avogadro’s number that there are 6.02214076×10^23 molecules per mole, so we multiply 25.53 by 6.02214076×10^23, which results in about 1.537×10^25 molecules.

Each of these Ionic Compounds are named INCORRECTLY.

1. Find and describe the mistake
2. Correctly name the compound.

CaCl2 - Calcium Chlorine

CuS - Copper Sulfide

Li3P - Trilithium Phosphide

CuBr - Copper(II) Bromide

NaOH - Sodium Hydrogen Oxide

Answers

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.

What is luminous ?

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.

When solid sodium hydroxide is dissolved in water,the temperature of the soution formed rapidly increases. a) compare the total energy of the solid NaOH with that of the solution and state which is greater.​

Answers

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.

Why is the nitrogen group considered a mixed group?

Answers

Explanation:

The nitrogen group is considered mixed because it is composed of elements of equally different classifications of metal, non-metal, and metalloids.  The group contains the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metals bismuth (Bi) and Moscovium (Mc).

In periodic table, metal, nonmetal and metalloids are mixed in group is know to be mixed group. Nitrogen group is mixed.

Define periodic table?

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number. There are five parts in periodic table Component Groups, Ionic Bonds, element periods, and so forth, ionic bonds and Bonds made of metal.

The nitrogen group is said to be mixed because it is contains metal, nonmetal and metalloids.

Use the following image to answer the following questions. A student was performing an experiment using two identical cups made of styrofoam. The student had Cup A holding water at 90℃ and Cup B holding water at 20℃. The student then put an Aluminum Bar into each cup that was touching the water. As time passed, the student noticed that the temperature of the water in Cup A and Cup B began to change. Question:
A. Predict what will happen to the temperature of the water in Cup A and Cup B after 1 hour has passed. (1 point)

B. Explain and give evidence for what type of heat transfer is occurring between the 2 cups.

Answers

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.

How is thermal energy transferred by convection, conduction, and radiation?

Answers

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.
