We know that the electron clouds of two atoms overlapping is a bond, because that signifies that the electrons are being shared in a bond.
So, I'm going to go through some definitions of these different types of bonds, because they have very specific circumstances.
<u>A hydrogen bond is a bond between an electronegative atom and a hydrogen molecule</u> (which is not what this question says, this isn't stated anywhere).
<u>A dipole is a difference in electron density on two different atoms</u> (so this isn't even close to what the question is stating, a dipole is not even a bond)
<u>An ionic bond is an </u><u><em>unequal sharing of electrons</em></u><u> between two atoms </u>(because the question doesn't state this specific fact, then it can't be this option).
By process of elimination, we know the answer is covalent bond, but just in case, we can also look at the definition of a covalent bond: <u>a bond that involves the sharing of electrons between atoms.</u>
That is exactly what the question is asking for! Therefore, your answer is d. covalent bond
NaCl + H2O = HCl + NaOH
FIRST write the equation and balance the equation THEN convert the volume of the gas to moles of the gas PV=nRT THEN according to the stoichiometry of the reaction one mol of gas is produced by one mol of salt. Convert the mol of gas to mol of salt FINALLY calculate the molar mass of the salt and convert the mol of salt to g of salt (m= nxMM)
18 I think. <span>Essentially because there are so many more orbitals used by the molecules placed in the series. You will see that group 1-8 molecules always have a number of valence electrons equal to the group number. This reflects s and p orbital useage. Once d and f orbitals begin to be needed, the atoms become much more complex.</span>
11 L because you just need to use a pie chart
Answer:
v = 1.5 m/s
Explanation:
Given that,
Distance covered by a person, d = 105 m
Time taken, t = 70 s
We need to find the average speed of the person. We know that the average speed is given by :
So, the average speed of the person is equal to 1.5 m/s.
