Answer:

Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.

A binary ionic compound is known to contain a cation with 51 protons and 48 electrons. The anion contains one-third the number o

7nadin3 [17]

Answer:

$SbCl_3$

Explanation:

The cation contains 51 protons and 48 electrons. The electrons are only lost not protons, so the element which corresponds to atomic number 51 is the cation which is Antimony (Sb).

Also, the charge on the cation is 51 - 48 = 3

This is because neutral atom contains the same number of electrons as protons.

Given the anion has one-third protons as cation which means thta:

Number of protons in anion = $\frac {51}{3}=17$

This corresponds to chlorine atom. The electrons are 1 greater than protons means that it has gain 1 electron.

So,

Sb Cl

3 1

Cross multiply the valency.

So, formula is $SbCl_3$

How many times greater is the hydronium ion concentration in rainfall (pH = 5.0) compared to pure water (pH = 7.0)?

joja [24]

Hydronium ion is H3O(+)

pH is log 1 / [H3O(+)] = - log [H3O(+)]

Rainfall: pH = 5.0 = - log [H3O(+)] => [H3O(+)] = -antilog (- 5.0) = 10^-5

Water; pH = 7.0 = - log [H3O(+)] => [H3O(+)] = - antilog (-7.0) = 10^ -7

Divide hidronium conentration of rainfall by hidrodium concentration of water:

10^-5 / 10^-7 = 10^2 = 100.

Then, hidronium concentration in rainfall is 100 times hidronium concentration in water.

Answer: option a. 100 times.
