How do valence electrons impact the type of bonds an atom makes?

An atom wants an empty outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
A large number of valence electrons means the atom will share electrons; a small number of valence electrons leads to transferring from one atom to another.
A small number of valence electrons means the atom will share electrons; a large number of valence electrons leads to transferring from one atom to another.
An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.

Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)(1 point)
O=C=O
C=O–O
C–O–O
O=C–O

Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?
Yes, there is because there are one too many hydrogen atoms for carbon to handle alone, so one hydrogen must bond with another.
No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.
Yes, there is because they form a long chain in order to all have stable outer energy shells.

In hydrogen peroxide (H2O2), which option best shows how the atoms are ordered?
H–O–O–H
O–H–H–O
H–O–H–O
O–H–O–H

Answer: Velocity is a mathematical vector. That means it has both a magnitude (speed) and a direction. Scientists need to consider an object’s velocity to calculate its momentum — its velocity multiplied by its mass. Scientists use measures of velocity in everything from figuring out how much rain is falling to sending a rocket to space.

Explanation:

GOLGI BODY - transportation of lipids and steroids.

LYSOSOME - destruction of malfunctioning or worn out cell organelles.

MITOCHONDRIA - oxides glucose to give energy to the cell in a form of cellular respiration.

VACUOLE - FOOD VACUOLE for storage of food while WATER VACUOLE eliminates excess water by a process called OSMOREGULATION.

CELL WALL - provides rigidity for the plant cell.

CHLOROPLAST - pigmented organelle of the plant which functions to manufacture food by a phenomenon known as PHOTOSYNTHESIS.

RIBOSOME - synthesizes protein and enzymes.

ENDOPLASMIC RETICULUM - The ROUGH ENDOPLASMIC RETICULUM has RIBOSOMES attached to it while the SMOOTH ENDOPLASMIC RETICULUM has nothing attached, they transport proteins and enzymes

Answer:

Once an enzymatic reaction is completed, the enzyme releases substrates.

Explanation:

The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

Answer:

Some varieties of potato, such as Russet and King Edward, are more suitable for baking than others, owing to their size and consistency. Despite the popular misconception that potatoes are fattening, baked potatoes can be part of a healthy diet.[2]

Answer:

I would say D) A new substance is formed with different properties.

It doesn't nesisarally have to have a specific change (except mass), but it could be a wide variety of changes.

Answer:

A New substances  form with different properties

Explanation:

When two different chemical substances are combined, they form new substances with different properties. The properties may be modified and the substance formed may exhibit better characteristic than individual properties of its components. For example, when sodium and chlorine combine, they form sodium chloride. Sodium chloride has different properties than any of the constituents.

Answer:

49.05 g

Explanation:

6co2+6h20-c6h120+602

Speed = v = 3×10⁸ m/s

Wavelength = λ = 5.8×10⁻⁷ m

Frequency = f  

v = fλ

Hence,

f = v/λ

f = 3×10⁸ / 5.8×10⁻⁷

f = 0.517×10⁸⁺⁷

f = 5.17×10¹⁴ Hz                                                                                                                                  

i hope this will help but if im wrong then it will be 5.16x10¹⁴

Answer:

Explanation:

I honestly don't know

Answer:

A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1) Elements consist of indivisible small particles (atoms). (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed.

Explanation:

Answer:

The balloon would fall because carbon dioxide, the gas you exhale and blew up with, is denser than air and therefore will fall. Helium however, is less dense than air and floats.

Answer:

Applied science is a discipline that is used to apply existing scientific knowledge to develop more practical applications, for example: technology or inventions. In natural science, basic science (or pure science) is used to develop information to explain phenomena in the natural world.

Answer:

• Because engineers apply science and its theories into practical situation

Take an example of;

→ A generator: When creating a generator, electromagnetic induction theorem is applied. [ self and mutual inductance ]

→ A plane: The wings are made in considerance of Bernoulli principle and viscous drag

Explanation:

The attached chart shows the calculation.  The orange line points to the % abundance of Cu-65, which is the difference of 100% less the % Abundance of Cu-65 (since there are only 2 isotopes).

The weighted average contribution of each istope is calculated (blue arrow) and then summed to find the atomic mass of copper.
