Tetrachloromethane, CCl4, is classified as a(1) compound because the atoms of the elements are combined in a fixed proportion
(2) compound because the atoms of the elements are combined in a proportion that varies
(3) mixture because the atoms of the elements are combined in a fixed proportion
(4) mixture because the atoms of the elements are combined in a proportion that varies

Answers

Answer 1

Answer: Correct Answer: compound because the atoms of the elements are combined in a fixed proportion.

Reason:
A chemical compound is a chemical substance composed of element (of same or different type) that are bonded in a fixed proportion. Depending upon the type of element, bond can be ionic or covalent. In present case, tetrachloromethane i.e. CCl4 has one 'C' atom that is covalently bonded to four 'Cl' atoms.

Answer 2

Answer: Tetrachloromethane, CCI4, is classified as a compound because the atoms of the elements are combined in a fixed proportion.

As the first five elements in Group 15 areconsidered in order of increasing atomic number,
first ionization energy
(1) decreases
(2) increases
(3) decreases, then increases
(4) increases, then decreases

Answers

The correct answer is option 1. The first ionization energy, in group 15 elements in increasing atomic number, decreases. Ionization energy is the amount of energy requires to detach one electron from the atom. In the periodic table, the ionization energy decreases as one goes down.

Answer: The first ionization energy for the first five elements of Group 15 decreases.

Explanation:

Ionization energy is defined as the energy required to remove an electron from the outermost shell of an isolated gaseous atom. It is represented as $E_i$

$X(g)\rightarrow X^+(g)+1e^-;E_i$

Ionization energy decreases as we move down the group. This happens because the number of shells increases as we move down the group. The electrons are added in the new shell around the nucleus.

This results in the shielding of outermost electrons more from the inner ones, which decreases the attraction between the outermost electrons and the nucleus. Hence, the removal of electron from the outermost shell becomes easy and requires less energy.

Hence, the first ionization energy for the first five elements of Group 15 decreases.

Which type of bond results when one or more valence electrons are transferred from one atom to another?(1) a hydrogen bond
(2) an ionic bond
(3) a nonpolar covalent bond
(4) a polar covalent bond

Answers

To solve this we must be knowing each and every concept related to an ionic bond. Therefore, the correct option is option 2 among all the given options.

What is an ionic bond?

Ionic bond, also known as electrovalent bond, is a kind of connection generated in a chemical molecule by the electrostatic attraction of oppositely charged ions.

Whenever the valence (outer portion) electrons with one atom are permanently transferred to another, a bond is formed.

The atom that loses electrons has become a positive ion (cation), whereas the atom that obtains electrons is becoming a negatively charged ion (cation) (anion). When one or more valence electrons are transferred from one atom to another, then the bond formed is an ionic bond.

Therefore, the correct option is option 2 among all the given options.

The type of bond that results when one or more valence electrons are transferred from one atom to another is the ionic bond. The answer is number 2. The rest of the choices do not answer the question above.

What would happen if u washed the benzoic acid in the Büchner funnel with hot solvent ? answer ASAP

Answers

Benzoic acid is able to dissolve in hot solvents. That means that it would not be filtered out by the buchner funnel since the buchner funnel has holes in it that make it so that the solvent can get through but solids can't (the benzoic acid would be dissolved in the solvent and therefore would leave the funnel with the solvent through the holes).

Note that it is important that the solvent is hot. Benzoic acid will start to precipitate out (re crystallize) as soon as the temperature drops which will make it so that some of the benzoic acid would get caught in the buchner funnel.

I hope this helps. Let me know in the comments if anything was unclear.

1. The following reaction does not proceed to form a product: H2O + Au---> no reaction. Why is that?A) Gold has a higher activity than hydrogen and cannot replace it.
B) Gold has a lower activity than hydrogen and cannot replace it.
C) The reaction cannot occur because water is a reactant.
D) The reaction proceeds too slowly to create products.

2. Which of the following is the balanced form of the equation C2H6 + O2 --> CO2 + H2O?

answer choices are attached A,B,C,D top to bottom

3. The equation 2NaNO3 + CaCl2 ---> 2NaCl + Ca(NO3)2 is balanced. How many atoms of sodium (Na) are there on either side of the equation?

A) one
B) two
C) four
D) six

4. All single-displacement reactions can be classified as another type of reaction as well. What type of reaction is that?

A) combustion
B) redox
C) synthesis
D) decomposition

5. If ions change places and a gas is formed, then what type of reaction is indicated?

A) double-displacement
B) synthesis
C) decomposition
D) single-displacement

Answers

1. B
The positive charge in water is provided by hydrogen, and gold provides the same charge. However, gold is not more reactive than hydrogen so it can not replace it in the compound.

2. In order to balance the equation, you must sure there are equal moles of each element on the left and right side of the equation:
2C₂H₆ + 7O₂ → 4CO₂ + ₆H₂O

3. The number of moles of sodium atoms on the left of the equation must be equal to the number of moles of sodium atoms on the right, as per the law of conservation of mass. The answer is B.

4. C.
A synthesis reaction usually results from single displacement because some element or compound is produced in its pure form

5. B.
The gas being produced is being synthesized.
