Answer:

protons: 8

neutrons: 9

Explanation:

the atomic number tells you how many protons are in a element. The mass is the number of protons + neutrons.

17 - 8 = 9 neutrons

There are 8 protons and 9 neutrons in the nucleus of the oxygen atom.

The atomic number of an atom is the number of protons in atom of an element.

It can also be defined as the number of electrons in a neutral atom of an element.

The mass number is the number of protons and neutrons in the nucleus of an atom of an element.

The proton number of the oxygen atom is 8

The neutron number is 17 - 8 = 9

Therefore, in the nucleus of the oxygen atom, there are 8 protons and 9 neutrons.

Answer

No you did not lose weight.

Explanation:

Weight is the force acting on an object, Gravity is a force on earth which does not apply to the moon so your weight may change depending in where you are but your mass will stay the same because mass measures the matter of an object ITSELF! Have a nice day....

Answer:

I would take my weight on Earth and divide it by  6. I'd weigh less because the gravitational pull on the Moon is less, and, weight is the measure of gravitational pull. I wouldn't "loose weight" because I'd weigh the same on Earth  as I did the day I left (give or take a few pounds).

Explanation:

The phrase that describes transmutation is ; ( A ) The conversion of an atom of one element into different element through nuclear changes.

Transmutation is simply the change of an element to another element, transmutation occurs at the nucleus of the atom of an element and this process is initiated through nuclear reaction ( radioactive decay ).

Therefore the conversion of an atom of one element into different element through nuclear changes summarizes the term "transmutation".

Hence we can conclude that the phrase that describes transmutation is  the conversion of an atom of one element into different element through nuclear changes.

The editorial blogs are considered an unreliable source because the author may not have a science background. Option C

We know that not all sources of information could be taken to be reliable. A source of information could come across as being reliable when the source is an authority in the area in which the information is furnished.

Such authorities often publish authentic and verified information in reputable journal that are meant for professional consumption.

Thus, the editorial blogs are considered an unreliable source because the author may not have a science background.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.46 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.053156[/tex]

Answer:

I and II

Explanation:

Explanation:

A. Hydrogen bonding is present in CS2 but not in CO2.

B. CS2 has greater dipole moment than CO2 and thus the dipole-dipole forces in CS2 are stronger.

C. CS2 partly dissociates to form ions and CO2 does not. Therefore, ion-dipole interactions are present in CS2 but not in CO2.

D. The dispersion forces are greater in CS2 than in CO2.

Explanation:

Glucose and galactose are monosaccharides that differ from one another only at position C-4. Thus, they are epimers that have an identical configuration in all the positions except in position C-4. ... Glucose and galactose are epimers that do not differ in position C-5 but differ in position C-4.

Glucose and mannose are epimers that differ at the C-2 carbon, while glucose and galactose are epimers that differ at the C-4 carbon, as shown below. When a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1.

Answer:

hydrogen bonding

Explanation:

The strongest among them is hydrogen bonding, and the weakest are London dispersion forces.

The strongest intermolecular force to overcome when ethanol is converted from liquid to a gas is hydrogen bonding.

Intermolecular forces are forces that are a weaker force of attraction than intramolecular forces.

Intermolecular forces are forces between molecules and hold these molecules together.

Hydrogen bonding is an example of intermolecular forces between the OH group in the alcohol.

During the conversion of ethanol from liquid to gas state,  hydrogen bonding occurs between the partial negative charge in the oxygen and the partial positive charge in the hydrogen.

Explanation:

number of moles = mass ÷ relative formula mass

e.g.

Calculate the number of moles of carbon dioxide molecules in 22 g of CO2.

Ar (relative atomic mass) of C = 12, Ar of O = 16

Mr (relative formula mass) of carbon dioxide = 12 + 16 + 16 = 44

number of moles = 22 ÷ 44 = 0.5 mol
