how many moles of carbon are in 3.0 moles of c6h12o6
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.
what is the total number of electrons found in the valence shell of noble gas in the ground state?
Answer:
eight
Because the noble gases are the least reactive of all elements, their eight valence electrons are used as the standard for nonreactivity and to explain how other elements interact.
Explanation:
A person aims for a target with a wooden bow and arrow. The image shows the path of the arrow to the target. How can the person increase the elastic potential energy in this situation? A) aim the bow higher, increasing the height of the arrows flight. B) sharpen the arrows tip, causing it to strike the target with more force. C) change the bow’s material, increasing the stiffness of the bow. D) pull the arrow farther back, increasing the stretch of the bows string.

What ion will be formed by the selenium atom shown below when it has a stable set of valence electrons?
Selenium atom
A. Se6+
B. Se2+
C. Se6-
D. Se2-
Answer:
Explanation:
D. Se2−
Selenium is in Group 16 of the periodic table, and it typically has 6 valence electrons. To achieve a stable set of valence electrons, it will either try to gain two more electrons to form Se²⁻or lose six electrons to form Se⁶⁺. Therefore, the correct option is option D.
An ion is an atom or a molecule that has gained or lost one or more electrons, resulting in an unequal number of protons and electrons. When an atom gains electrons, it becomes negatively charged and is called an anion. Conversely, when an atom loses electrons, it becomes positively charged and is called a cation.
Ions play a crucial role in chemical reactions and the formation of chemical compounds, as they are attracted to one another based on their opposite charges. This process helps stabilize the electron configuration and achieve a more stable, lower-energy state.
Thus, the ideal selection is option D.

Is it OK for people to post fake vacation pics and other fake info on social media? Why or why not? Use facts and details from the Article to back up your answer.
Answer:
No, It is not okay to pretend on social media.
Explanation:
No, it is not okay for people to post fake vacation pics and other fake info on social media. This is very wrong, as -
This 'all time look good, feel good, have a happening life' approach of social media - implies showing only the positive side & not negative side of people's life. However, in real life is not a bed of roses. Faking things out implies that pretending to be cool has become more important than sharing deep meaningful relationships, & highlights superficial desire of false popularity. It is also harmful to people being communicated this fake image, as they might indulge into any social involvement, on the basis of unreal image of the concerned person.Answer:
it is not ok because there are other people that will look at those pictures and say aww i wish i were them but we all need to exept who we are

Seeing that the chemicals present are in question one I take it you are asking about that question.
Decreasing the concentration causes a decrease in reaction process and also the total amount of product you would get out of the given reaction
Decreasing the temperature causes the molecules in this reaction to become less excited or reactive, thus causing the reaction to slow down
what is the name for C3Cl8 and is it a covalent or polar covalent bond?
Answer:
Propane, octachloro- | C3Cl8 - PubChem
The name of C3Cl8 is octachloropropane. It is a covalent bond.
What are covalent bonds ?Covalent bonds are formed when two atoms share electrons. In the case of octachloropropane, the carbon atoms share electrons with the chlorine atoms. The electrons are shared unequally, so the bond is polar covalent.
The name octachloropropane is derived from the Greek words "octo" (eight) and "chloro" (chlorine). The prefix "octa" refers to the number of chlorine atoms in the molecule. The suffix "propane" refers to the three carbon atoms in the molecule.

Convert 3.55 moles Nacl to formula units
Answer:
2.14 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of NaCl = 3.55moles
Unknown:
Formula units of NaCl = ?
Solution:
A mole of substance contains the avogadro's number of particles. The number of particles could be protons, atoms, neutrons, formula units etc.
1 mole of substance = 6.02 x 10²³ formula units
3.55 mole of NaCl = 3.55 x 6.02 x 10²³
= 2.14 x 10²⁴ formula units
