In order to expand agriculture and urban areas to meet increased demand for growing populations, water supplies often have to be

diverted. In three to five sentences, construct a potential chain of consequences for what could happen when water is diverted from large bodies like lakes and rivers.

Why is second ionization energy larger than first ionization energy
rodikova [14]

Hi!

Why is second ionization energy larger than first ionization energy?

The reason second ionization energy is larger is because it takes more energy to remove an electron from a poistively charged ion than it does from an neutral atom.

Which reaction does not occur?
balu736 [363]

Answer: 2HF(aq)+Cl_2(g)\rightarrow F_2(g)+2HCl(aq) will not occur.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

X+YZ\rightarrow XZ+Y

a) 2HF(aq)+Cl_2(g)\rightarrow F_2(g)+2HCl(aq)

Flourine is more reactive than chlorine and hence this reaction cannot occur.

b) 2Na(s)+ZnF_2(aq)\rightarrow 2NaF(aq)+Zn(s)

Sodium is more reactive than zinc and hence the reaction will occur.

c) Fe(s)+CuCl_2(aq)\rightarrow FeCl_2(aq)+Cu(s)

Iron is more reactive than copper and hence the reaction will occur.

d) 2HCl(aq)+Mg(s)\rightarrow MgCl_2(aq)+H_2(g)

Magnesium is more reactive than hydrogen and hence the reaction will occur.

"the osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant
ASHA 777 [7]

Answer: -

The concentration is 0.91 mol/ L

Explanation: -

The osmotic pressure = 23 atm

Absolute temperature = 309 K

Universal gas constant = 0.08206 L atm mol⁻¹ K⁻¹

We know the formula

Osmotic pressure = molar concentration x universal gas constant x absolute temperature

Plugging in the values

23 atm = molar concentration x 0.08206 L atm mol⁻¹ K⁻¹ x 309 K

Molar concentration = \frac{23}{0.08206 x 309} mol/ L

                                  = 0.91 mol / L
