Identify The Element By Its Symbol And Name After Looking At The Element Model Pictured Below. Symbol:

Answers

Answer 1

Symbol: O

Name: Oxygen

as number of protons + number of neutrons = atomic mass

8+8=16

Answer 2

The element is Oxygen (O) in the given element model.

The atomic number of an element is equal to the number of protons in its nucleus. Since the element in question has 8 protons, its atomic number is 8. Oxygen has an atomic number of 8, making it the element with 8 protons. Additionally, the atomic number determines the identity of an element; no other element has 8 protons in its nucleus.

The element's name is Oxygen, and its chemical symbol is O. Oxygen is a vital element in the Earth's atmosphere and is essential for supporting life. It is commonly found in the form of diatomic molecules (O2), which make up a significant portion of the air we breathe. Oxygen plays a crucial role in various biochemical and chemical processes, and its presence is essential for the respiration of most living organisms.

Ethan makes the table below to record his observations when mixing baking soda and vinegar in a beaker. Ethan claims that a chemical change has occurred. Which statement provides the BEST evidence to support his claim?

Answers

Answer: a

Explanation:

Many bubbles formed after mixing.

The statement which best provides support for the fact that a chemical change has occurred is that many bubbles formed after mixing.

In a chemical change, new substances are formed and there is a recombination of the atoms in reactants as the products are being formed.

There are several cues that indicate that a chemical change has taken place such as;

Appearance of a solid in an aqueous phase reaction.Evolution of gasSudden change in the temperature of the systemChange in the color of the system

In the particular instance in this question, when baking soda and vinegar were mixed together, a gas was evolved signifying that a chemical change has taken place.

The total pressure in a mixture of gases is equal to the partial pressure(s) of ________. the gas that occupies the largest volume the gas with the smallest number of moles all the gases added together the gas with the highest molecular weight the gas with the greatest number of moles

Answers

The total pressure in a mixture of gases is equal to the partial pressure of all the gases added together

According to Dalton's Law of Partial Pressure,  The total pressure exerted by a mixture of gases which are non reacting is equal to the sum of the partial pressure of each individual gas that make up the mixture

Mathematically, Ut can be written as

P{total}= p1+p2, ....+ pn

where p1, p2, …, pn are partial pressures of each gas component.

For example :A gaseous mixture consisting of Helium and Nitrogen gas . If the pressure exerted by He is 3 atm while Nitrogeb exerted is 9 atm. The total pressure will be:

P{total}= p1+p2, ....+ pn

P{total}= 3+9

P{total}= 12

When the metallic element sodium combines with the nonmetallic element bromine (Br2), is the product a solid, liquid, or gas at room temperature?

I will give brainliest if you can explain how one would know this information.

Answers

Answer: it is a solid at room temperature.

Explanation:

The ions of the two reactants are Na{+} and Br{-}, so the formula of the product is NaBr.  

and when the NaCl is a solid a room temperature. and when NaBr has similar properties to NaCl, so NaBr is a solid at room temperature too.

so our chemical formula for the product is NaBr and It's a solid at room temperature.

Balance the following chemical equation and determine the number of moles of Fe(s) produced when 8.1E-1

Fe2O3(s) + C(s) ——)Fe(s) + CO2(g)

Answers

Answer:

2Fe2O3 + 3C → 4Fe + 3CO2

Explanation:

The balanced reaction of Ferric oxide with carbon to form Iron and Carbon dioxide can be written as follows:

[tex]2Fe_{2} O_{3} +3C\rightarrow4Fe+3CO_{2}[/tex]

The moles of iron produced is[tex]16.2*10^{-1}[/tex]

What is balanced equation?

Balanced equation is the one where the number of atoms of each species is same on reactant and product side. In balanced equation mass can neither be created nor be destroyed.

The atoms of Oxygen on reactant side is 3 while on product side is 2 so multiply Ferric oxide by 3 and carbon dioxide by 3

so now our equation becomes

[tex]2Fe_{2} O_{3} +C\rightarrow Fe+3CO_{2}[/tex]

The number of Carbon atoms on left side is one while on right side it is 3 so multiply by 3

[tex]2Fe_{2} O_{3} +3C\rightarrow Fe+3CO_{2}[/tex]

The number of Iron atoms on left is 4 while on right it is 1 so multiply by 4

[tex]2Fe_{2} O_{3} +3C\rightarrow4Fe+3CO_{2}[/tex]

From 2 moles of Ferric oxide 4 moles of iron is produced

from 1 mole mole of ferric oxide 2 moles of Iron is produced

From [tex]8.1*10^{-1}[/tex] mole of ferric oxide 2×[tex]8.1*10^{-1}[/tex] moles of iron are produced.

Hence the balanced equation is

[tex]2Fe_{2} O_{3} +3C\rightarrow4Fe+3CO_{2}[/tex]

the number of mole of Iron is [tex]16.2*10^{-1}[/tex]

Vitamin D is produced in the skin when 7-dehydrocholesterol reacts with UVB rays (ultraviolet B) having wavelengths between
270 nm and 300 nm. What is the energy range of the UVB photons?

Answers

UVB photons, with wavelengths between 270 nm and 300 nm, have energies in the range of 6.63 × 10⁻¹⁹ J - 7.37 × 10⁻¹⁹ J.

UVB rays have wavelengths (λ) between 270 nm and 300 nm. We can calculate the energy (E) associated with each wavelength using the Planck-Einstein's relation.

[tex]E = \frac{h \times c}{\lambda }[/tex]

where,

h: Planck's constant (6.63 × 10⁻³⁴ J.s)c: speed of light (3.00 × 10⁸ m/s)

The energy associated with a wavelength of 270 nm is:

[tex]E = \frac{h \times c}{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times10^{8}m/s )}{270 \times 10^{-9}m } = 7.37 \times 10^{-19} J[/tex]

The energy associated with a wavelength of 300 nm is:

[tex]E = \frac{h \times c}{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times10^{8}m/s )}{300 \times 10^{-9}m } = 6.63 \times 10^{-19} J[/tex]

Answers

Answer:

By definition, a molecule is a group of atoms bonded together. This means that it can be a mixture of two separate atoms (e.g. atom A and atom B bond together to make molecule AB). Molecules with two or more separate elements are called compounds.

Molecules can also be made of more than one atom of the same element (e.g. atom A bonds to another A atom to make molecule AA). This is not called a compound because they are not different elements.
