Which energy source produces carbon dioxide?a. plutonium
b. uranium
c. sunlight
d. natural gas

Answers

Answer 1

Answer: The answer is d. natural gas. All the other choices are alternative sources of energy, and do not produce or emit any greenhouse gas such as carbon dioxide (CO2). Natural gas, on the other hand, is an organic substance containing a significant amount of carbon, that when burned for fuel, results in the emission of CO2.

In which substance does hydrogen have an oxidation number of zero?

Answers

Answer is: H₂ (molecule of hydrogen).

Missing question: A) LiH B) H₂O C) H₂S D) H₂.
1) In lithium hydride (LiH), lithium has oxidation number +1, than hydrogen must have oxidation number -1, because compound has neutral charge.
2) In water molecule (H₂O), oxygen has oxidation number -2 and hydrogen has +1: 2x + (-2) = 0; x = +1.
3) In hydrogen sulfide (H₂S), sulfur has oxidation number -2 and hydrogen has +1: 2x + (-2) = 0; x = +1.
4) In molecule of hydrogen there is nonpolar covalent bond.

A certain compound is made up of one phosphorus (P) atom, three chlorine (Cl) atoms, and one oxygen (O) atom. What is the chemical formula of this compound?

Answers

Ok so we know that all of these are non metals therefore they will bond using covalent bonds.
Phoshorus can have 3 bonds Chlorine can have 1 bond and Oxygen can two bonds.

The chemical formula I belive is PClO hope this helps :).

Suppose you have designed a new thermometer called the x thermometer. On the x scale the boiling point of water is 129 ?x and the freezing point of water is 13 ?x. Part a at what temperature are the readings on the fahrenheit and x thermometers the same?

Answers

(x1,y1) (x2,y2)

(32,15) (212,135)

y = mx + b

m=(y2-y1)/(x2-x1)

m=.66667

y = .66667*(x) + b

Plug in #s to test for b value

15 = .66667*(32) + b

b = -6.334

y = mx + b

y = .6667*(x) + (-6.334)

F = .6667*(F) + (-6.334)

F = (.6667*(F) = -6.334

(F - .6667F) = -6.334

F(1 - .6667) = -6.334

F = -19

ThermX = F @ -19 degrees

Rutherford’s gold foil experiment gave evidence that an atom is mostly empty space. true false

Answers

The given statement is true .

What is Rutherford’s gold foil experiment?

A piece of gold foil was hit with alpha particles, which have a favorable charge. Most alpha particles went right around. This showed that the gold particles were mostly space.

The Rutherford gold leaf investigation supposed that most (99%) of all the mass of an atom is in the middle of the atom, that the nucleus is very small (105 times small than the length of the atom) and that is positively captured.

For the distribution experiment, Rutherford enjoyed a metal sheet that could be as thin as practicable. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford established a gold foil for his alpha-ray scattering experimentation.

A scientist discovers a new substance. The molecules of the substance form hydrogen bonds with each other. When the molecules lose a lot of energy, the hydrogen bonds hold them relatively far apart. Based on this information, what can the scientist infer about the substance?

Answers

Answer is: It expands when it freezes.

When molecule frezes, it lose energy. When molecules are far apart, it means the volume is greater and it expands.

For example, ice expands when water is freezing.

Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.

The more the heat energy present in it the bond between the molecules gets weaker just like water

Which is a cause of polarity in water molecules? partial negative charge on the hydrogen atoms partial positive charge on the oxygen atom high electronegativity difference between oxygen and hydrogen low electronegativity difference between oxygen and hydrogen

Answers

Answer:

high electronegativity difference between oxygen and hydrogen

Explanation:

Final answer:

Water molecules become polar due to the difference in electronegativity between the oxygen and hydrogen atoms. This leads to the development of partial positive charges on the hydrogen atoms and a partial negative charge on the oxygen atom. These polar bonds allow for the formation of hydrogen bonds with other molecules.

Explanation:

Water is a polar molecule, with the hydrogen atoms acquiring a partial positive charge and the oxygen a partial negative charge. This occurs because the nucleus of the oxygen atom is more attractive to the electrons of the hydrogen atoms than the hydrogen nucleus is to the oxygen's electrons. Thus oxygen has a higher electronegativity than hydrogen and the shared electrons spend more time in the vicinity of the oxygen nucleus than they do near the nucleus of the hydrogen atoms, giving the atoms of oxygen and hydrogen slightly negative and positive charges, respectively. Another way of stating this is that the probability of finding a shared electron near an oxygen nucleus is more likely than finding it near a hydrogen nucleus. Either way, the atom's relative electronegativity contributes to the development of partial charges whenever one element is significantly more electronegative than the other, and the charges generated by these polar bonds may then be used for the formation of hydrogen bonds based on the attraction of opposite partial charges. (Hydrogen bonds, which are discussed in detail below, are weak bonds between slightly positively charged hydrogen atoms to slightly negatively charged atoms in other molecules.) Since macromolecules often have atoms within them that differ in electronegativity, polar bonds are often present in organic molecules.
