how many moles of carbon are in 3.0 moles of c6h12o6

Answers

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 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)

Answers

The correct answer is b

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 of the following contains the most atoms?
24.305 g Mg
39.098 gk
21.62 g B
9.0122 g Be

Answers

Explanation:

9.0122 g be Maybe, sorry i don't think so

In the above , the sample of B 21.62 g of boron contains the most atoms because it has approximately 2 moles, while the other samples have only 1 mole each.

What is atoms

The molar mass of each element can be found on the periodic table.

The molar mass of Mg (magnesium) is about 24.305 g/mol.The molar mass of K (potassium) is about 39.098 g/mol.The molar mass of B (boron) is approximately 10.81 g/mol.The molar mass of Be (beryllium) is about  9.0122 g/mol.

To calculate the number of moles in each sample, we divide the mass of each sample by its respective molar mass:

For Mg: Number of moles = 24.305 g / 24.305 g/mol = 1 moleFor K: Number of moles = 39.098 g / 39.098 g/mol = 1 moleFor B: Number of moles = 21.62 g / 10.81 g/mol ≈ 2 molesFor Be: Number of moles = 9.0122 g / 9.0122 g/mol = 1 mole

Therefore, the sample with 21.62 g of boron (B) contains the most atom

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.

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?

Answers

Given:

The overall average speed = 25 cm/s.

The overall average speed increased by 10%.

To find:

The new overall average speed.

Solution:

We have,

Overall average speed = 25 cm/s.

The overall average speed increased by 10%. So, the new average speed is

New overall average speed = Initial average speed + 10% of initial  overall average speed

[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]

[tex]\text{New overall average speed}=25+2.5[/tex]

[tex]\text{New overall average speed}=27.5[/tex]

Therefore, the new overall average speed is 27.5 cm/s.

Wegener did not use climatic evidence to proof continental drift. He did use fossils found on different continents such as the mesosaurus to propose the theory of continental drift. Wegener also used evidence of glacial sediments to justify his claims. He also fitted the earth into a giant puzzle.

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.

Answers

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.
