Explanation:
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.

which reaction is faster?why?
Answer:no answer
Explanation:
Temperature. Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate.
Which of the following is a balanced equation for the reaction described below?
Aqueous copper (II) chloride reacts with solid aluminum to produce aqueous aluminum chloride and solid copper.
A) CuCl2(aq) + Al(s) = AlCl3(aq) + Cu(s)
B) 3Cu2 Cl(aq) + Al(s) = AlCl3(aq) + 6Cu(s)
C) CuCl(aq) + Al(s) = AlCl(aq) + Cu(s)
D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)
The balanced equation for the reaction is
3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s). The correct option is - D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)
From the question,
We are to determine which of the given equation for the described reaction is balanced.
The described reaction is the reaction between aqueous copper (II) chloride and solid aluminum to produce aqueous aluminum chloride and solid copper.
That is,
CuCl₂(aq) + Al(s) = AlCl₃(aq) + Cu(s)
Now, we will balance the above equation, using the smallest whole number coefficients
The balanced equation for the reaction is
3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s)
Hence, the balanced equation for the reaction is
3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s). The correct option is - D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)

Which type of bond shares the electrons between two elements?
Answer:
Covalent Bonds
General Formulas and Concepts:
Different types of bondsExplanation:
We have 3 types of bonds: Polar Covalent, Nonpolar Covalent, and Ionic bonds.
Nonpolar Covalent bonds share the electrons equally between the compound.
Polar Covalent bonds do NOT share the electrons equally, but STILL SHARE the electrons; the electron tends to stay with the element with the stronger electron affinity and thus creates dipoles.
Ionic bonds DO NOT share electrons. The electrons are transferred to the respective elements.

Quantum Mechanics relies on probability to say what region of space an electron ismostlikelyto occupy. In your own words, describe how this principle results in the shapes ofthe orbitals.
Answer:
Explanation:
Since electrons are particles that are in constant movement in a wave-like motion, is impossible to know exactly their position and velocity at all times. That's why instead of defining an orbit for them we define an atomic orbital, which is a location in space where the probability of finding an electron is high (therefore, is an electron dense zone). Since this zone has not defined limits (the wave function characterizing the orbital extend from the nucleus to infinity), the further we go from the nucleus the less dense this "cloud" is.
There is about a 90 percent probability of finding the electron within a sphere of radius 100 pm surrounding the nucleus. Thus, we can represent the 1 s orbital by drawing a boundary surface diagram that encloses about 90 percent of the total electron density in an orbital, and the shape of this orbital is a sphere.
The boundary surface diagrams of p orbitals, for example, will have the shape of two lobes on opposite sides of the nucleus, that means that within this two lobes we have a 90 percent probability of finding the electron, and so on.
a student places a small stone with a mass of 5 g into a graduated cylinder containing 50 mL of water. With the stone in the graduated cylinder, the water rises to 75 mL. What is the density of the stone?
Answer:
The answer is 0.2 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 75 - 50 = 25 mL
We have
[tex]density = \frac{5}{25} = \frac{1}{5} \\ [/tex]
We have the final answer as
0.2 g/mLHope this helps you

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

In experiment B. the iron filings weighed 2.0g at the beginning of the experiment
and the iron sulphide produced weighed 2.8g.
Explain this increase in mass.
Explanation:
The increase in mass is because the iron fillings have combined with a sulfide to produce iron sulfide and so the mass will increase.
In such a reaction like this, the mass of the reactants must be conserved. By so doing, the mass of reactants and products must be the same.
When two substances combine together, their masses added up to that of the individual masses. This helps to conserve the mass.

A scientist is breeding orange butterflies in the laboratory she notices a white butterfly in the latest generation of animals she sequences the genome of this butterfly in notices a mutation in the genes that calls for pigment in the wings. Explain how this mutation would result in a white butterfly.
Answer:
See explanation
Explanation:
A gene mutation can be defined as a permanent change in the DNA sequence that composes a gene, resulting in the observation that the sequence differs from what is obtainable in most individuals that make up the population. Mutations range from a change in a single DNA building block (change in the sequence of base pairs) to changes in a large segment of a chromosome that includes multiple genes.
Mutation in the color of the wings of the housefly can be passed on to the next generation. If this trait enhances survival of the butterflies, the orange winged butterflies will eventual become extinct and become entirely replaced by the white winged butterflies. This implies that gene pool has been completely modified.
If same kind of mutation of pigmentation of wings is observed in the butterfly then they will result in a white butterfly.
What is mutation?If a gene of the DNA get damaged or changes in such a way that it also results in the changing of genetic message carried by that gene and this process is known by the name of mutation.
In the given question by breeding orange butterfly with a white butterfly in the latest generation of animals, notices a mutation in the genes that calls for pigment in the wings. If the mutation of pigmentation of wings is passed to the next generations with the same changes in the gene of DNA, then after some generation we would get white butterfly.
Hence, if the same changes observed in the mutation of pigmentation of wings then we get a white butterfly.
