The list which includes only bulk properties of matter is: C. boiling point, surface tension, vapor pressure.

What is matter?

Matter can be defined as anything that has mass and can occupy space.

Thus, any physical object or substance that is found on planet Earth is typically composed of matter.

The three (3) states of matter:

Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;

A bulk property of matter refers to the property that affects matter as a whole and they are listed as follows:

1. Stress

2. Strain

3. Elasticity

4. Boiling point

5. Surface tension

6. Vapor pressure

In conclusion, the other list of properties are not a bulk property of matter.

Answer:

Negative ion with one extra electron.

BRAINLIST Pls

Anions are the name for ions that have a negative charge. The body contains several common chemicals as ions. Sodium, potassium, calcium, chloride, and bicarbonate are typical examples.

Negatively charged electrons are called anion. When non-metals gain electrons, they are produced. They absorb one or more electrons. They have a negative charge overall as a result. The ion concentration iodide ( I- ), chloride ( Cl- ), and hydroxide are among examples ( OH– ).

The electrode where reduction takes place in any electrochemical cell  is characterized as the cathode. On the other extreme, the positive electrode will draw anions, or negative ions, to itself.

Thus, when an atom obtains electrons, it transforms into the negatively-charged ion known as an anion.

THE % Al IS (54 /344) X 100 = 15,7%

Answer:

the second ionization energy

Explanation:

The second ionization energy is always larger than the first ionization energy, because it requires even more energy to remove an electron from a cation than it is from a neutral atom.

The rearrangement produces a more stable tertiary carbocation and the unexpected product.

In the image shown, the substrate is 1-cyclobutylethene. The attack of H2SO4 and water will lead to the conversion of the alkene to an alkanol. Two possible products may be obtained with one being greater than the other.

The unexpected product (Shown in the image attached) is obtained due to rearrangement of the carbocation intermediate. The rearrangement produces a more stable tertiary carbocation and the unexpected product.

The element that is being reduced in the given redox reaction is Cl (Chlorine)

The given redox reaction is

Cr(OH)₄⁻(aq) + ClO⁻(aq) → CrO₄²⁻(aq) + Cl⁻(aq)

First, we will define the terms oxidation and reduction

Oxidation can be defined as an increase in oxidation number

Reduction is defined as a decrease in oxidation number

This means the element that is being reduced in the reaction would have a decrease in oxidation number.

Oxidation number of Cr in Cr(OH)₄⁻ is +3; and the oxidation number of Cr in CrO₄²⁻ is +6. This is an increase in oxidation number and it means Cr is being oxidized.

Oxidation number of Cl in ClO⁻ is +1; and the oxidation number of Cl in Cl⁻ is -1. This is a decrease in oxidation number and it means Cl is being reduced.

Hence, the element that is being reduced in the given redox reaction is Cl (Chlorine).

BeF2

Explanation:

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

The valence electron of an atom determines how an atom goes into bonding.

Beryllium(Be) has 4 electron and has 2 valence electron. To fulfil the octet rule, it can easily give out this 2 electron during bonding.

Fluorine(F) has 9 electrons and 7 valency electrons. To fulfil the octet rule, it readily accepts a single electron.

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

This means 1 atom of beryllium combines with 2 atoms of fluorine to form beryllium fluoride. The beryllium give its 2 valency electrons to the 2 atoms of fluorine. The 2 atoms of fluorine will now have a valency electron of 8 each. The octet rule has been fulfilled at this point.

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons

Answer:

c.) feeling the heat from a lightbulb with your hand when touching the bulb

Explanation:

In heat transfer by conduction, feeling the heat from a lightbulb with your hand when touching the bulb will be categorised as the best condition.

After beginning the experiment with a saturated solution, then increasing the heat, we will be left with an unsaturated solution.

To obtain the saturated solution, we must dissolve sugar in the water. We can say that the solution has become saturated when the solution is no longer able to dissolve more sugar. It has reached its capacity for the solute that it can dissolve in these conditions.

However, the temperature of a solution has an effect on the dissolving limit of the solution. That is, when a solution is heated it becomes able to dissolve more solute. Therefore, if we were to heat a saturated solution, it will be able to dissolve more solute and therefore will no longer be at its limit, meaning it is no longer a saturated solution. It has become unsaturated.

This question is mentioning an experiment that is not being described about the volume of the propane gas in an Erlenmeyer before the addition of water.

In this case, since no information is given, it is possible to propose a suggested procedure of how to figure it out via gas laws, specifically, the ideal gas one, since no change is decribed before the addition of water:

[tex]PV=nRT[/tex]

Thus, you can solve for the volume, by dividing both sides by the pressure, so that you will get:

[tex]V=\frac{nRT}{P}[/tex]

Now, to ensure a correct calculation, make sure you have the moles (divide by the molar mass of propane, 44,1 g/mol, if you were given the grams), the temperature in K (add 273.15 if you have degree Celsius), the ideas gas constant as 0.08206 and the pressure in atm, in order to have consistent units.

If you need the volume in milliliters, you will need to multiply the previous answer by 1000 in order to perform the appropriate conversion.
