Answer:

both bonding electrons come from the oxygen atom

Explanation:

A coordinate covalent bond is said to be formed when an electron pair is donated into a empty orbital of an atom from a filled orbital of another atom.

In this type of covalent bond, the shared electron pair is furnished by only one of the bonding species.

The bonding between H^+ and H2O to form H3O^+ involves donation of a lone pair of electrons on oxygen into the empty 1s orbital of H^+ hence the two bonding electrons come from oxygen. This is why the bond is called a coordinate covalent bond.

1.2 What type of bonding occurs when hydrogen form a diatomic molecule?

Irina-Kira [14]

Answer:

I think it is covalent bonding...

Explanation:

The bonding is covalent in homonuclear diatomic molecules. Each atom in the molecule has the same electronegativity, which means electrons are shared equally between the two. The electronegativity of the atoms in heteronuclear diatomic molecules varies, and these molecules have polar covalent bonds. A dipole is formed when a molecule interacts with another molecule. (i think it's covalent bonding but i might be wrong)

hope this helps...

What would happen if N2 were added to N2(g) + O2(g) = 2NO(9) at

DerKrebs [107]

Balanced chemical equation is :

$N_2(g)+O_2(g)-->2NO(g)$

It is given that the equation is in equilibrium.

We need to find what will happen if we add more $N_2$ is added .

By Le Chatelier's principle :

Changing the concentration of a chemical will shift the equilibrium to the side that would counter that change in concentration.

It means production of the side where content is added will decrease and concentration on other side will increase .

So , more NO would form .

Therefore, option B. is correct.

Hence, this is the required solution.

Given an acidic solution with a pH of 4.5, what is pOH of the same solution?

Crazy boy [7]

Answer: Option C) 9.5

Explanation:

Given that,

pOH of solution = ?

pH of solution = 4.5 (it is an acidic solution because any pH values less than 7.0 is said to be acidic)

Recall that pH is the negative logarithm of hydrogen ion concentration in the solution while pOH is the negative logarithm of hydroxide ion concentration in the solution.

Hence, pH + pOH = 14

4.5 + pOH = 14

pOH = 14 - 4.5

pOH = 9.5

Thus, the pOH of the same solution is 9.5

What if you broke off a piece of cement (or bread) so that it was only half the volume of the original piece? What would happen

MAVERICK [17]

Answer:

The mass is also half of the mass of the original piece

Explanation:

Recall that the volume of a substance is defined as mass/volume. The density of substances is a constant. Hence, if a break off a piece of cement or bread such that what remains is only half the volume of the original piece, the mass of the new piece must also reduce to half of the mass of the original piece so that the volume of the material will remain constant.

Hence the answer above.

Determine how many atoms of pure silver will be created when 19.83 x 1023 atoms of copper are used in the following reaction:

nadezda [96]

Answer : The number of silver atoms produced will be $39.66\times 10^{23}$

Explanation : Given,

Number of atoms of copper = $19.83\times 10^{23}$

The given balanced chemical reaction,

$Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag$

From the balanced chemical reaction we conclude that,

As, $6.02\times 10^{23}$ number of copper atoms react to give $2\times 6.02\times 10^{23}$ number of silver atoms.

So, $19.83\times 10^{23}$ number of copper atoms react to give $2\times \frac{6.02\times 10^{23}}{6.02\times 10^{23}}\times 19.83\times 10^{23}=39.66\times 10^{23}$ number of silver atoms.

Therefore, the number of silver atoms produced will be $39.66\times 10^{23}$
