Draw all the structural isomers for the molecular formula C3H8O. Be careful not to draw any structures by crossing one line over

another; the system needs to know where you intend connections to be between atoms.

An inner and an outer membrane are characteristic of which organelle? (site 1)
AlexFokin [52]
The mitochondria are suspended in the jelly-like cytosol of the cell. They are oval-shaped and have two membranes: an outer one, surrounding the whole organelle, and an inner one, with many inward protrusions called cristae that increase surface area.

Glucose, a common carbohydrate, is a molecule that contains the elements carbon, hydrogen, and oxygen. Complete combustion of a
lesya [120]

The formation of carbondioxide is given by equation as

C + O2 ----> CO2(g)

As per balanced equation one mole of carbondioxide is obtained from one mole of carbon

if 44 g of CO2 is formed it means it contains 12 g of carbon

if 1g of CO2 is formed it means it contains 12/44 g of carbon

if 0.528g of CO2 is formed it means it contains = 12 X 0.528 / 44 g of carbon

                                                                           = 0.144g of carbon

Similarly for water

H2 + 0.5O2 ---> H2O

so one mole of water is obtained from one mole of H2

if 18g of water is formed it means 2g H2 is present

if 1g of water is formed it means 2/18 g of H2 is present

if 0.216g of water if formed it means 2 X 0.216 / 18g of H2 is present = 0.024g of Hydrogen

In glucose we have Carbon , Hydrogen and oxygen

As given the total mass of sample = 0.360g

Mass of carbon = 0.144 , moles of carbon = 0.144 / 12 = 0.012

Mass of hydrogen = 0.024 , moles of hydrogen = 0.024 /1 = 0.024

mass of oxygen = 0.360 - (0.144+0.024) = 0.192

Moles of oxygen = 0.192 / 16 = 0.012

So mole ratio of C : H : O = 0.012 : 0.024 : 0.012 = 1:2:1

Empirical formula = CH2O

Which of the following statements about material bonding is correct? C O a. Ionic bonds are formed by the sharing of valence ele
Zina [86]

Answer: Option (b) is the correct answer.

Explanation:

In material bonding, there occurs Vander waal foces between the molecules in which their is either an induced or permanent dipole moment that attract molecules towards each other.

And, due to these forces the molecules are held together.

On the other hand, in a ionic bond there will always be transfer of electrons from one atom to another. This is because on atom which loses its valence electrons acquires a positive charge and another atom which gains the electrons acquires a negative charge.

Hence, these opposite charges strongly gets attracted towards each other forming a strong bond.

Whereas in a covalent bond, there will be sharing of electrons between the combining atoms.

In a metallic bond, there occurs a sea of electrons which is uniformly distributed throughout the solid substance or material.

Thus, we can conclude that the statement, Van der Waals bonds are formed by Van der Waals forces in which molecules or atoms have either an induced or permanent dipole moment to attract each other, about material bonding is correct.

Hey please answer this for me thanks.
Aleks [24]

Explanation:

Moles of N2 = 84/28 = 3.0mol

Moles of H2 = 29/2 = 14.5mol

Hence amount of ammonia produced = 6.0 * 17 = 102g.
