Did you mean ionic? An ionic bond donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The word “Covalent” has “co” in it, and “co” means “together”. They come together to share electrons, while ionic just donates electrons to another element. I’m not sure if that helps any but I tried.

One method of removing phosphate from wastewater effluents is to precipitate it with aluminum sulfate. A plausible stoichiometry

Viktor [21]

Answer: The equation is written below.

Explanation:

$2PO_4^{3-}(aq)+Al_2(SO_4)_3(aq)\rightarrow 2AlPO_4(s)+3SO_4^{2-}(aq)$

According to Stoichiometry of the reaction:

2 moles of phosphate ions reacts with 1 mole of aluminum sulfate to produce 2 moles of aluminum phosphate precipitate and 3 moles of sulfate ions.

Aluminum phosphate is an odorless and white crystalline solid

The chemical equation is written above.

Suppose Highlinium-308 can also undergo positron emission

____ [38]

Answer:

The atomic number of burienium will be 307.

Explanation:

During positron emission proton is converted into the neutron and one electron neutrino with positron is released. It means the atomic number will be reduce by one and atomic mass remain same.

For example:

²³Mg₁₂ → ₁₁Na²³+ e⁺+ Ve

Similarly, when highlinium-308 undergoes positron emission the new element burienium is produced and the atomic number will be 307 while atomic mass remain same.

Properties of beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation

A sample of black coffee was measured to have [h3o+] = 7.94 × 10−6. what is true about this solution?

Sveta_85 [38]

Being given the hydronium (or simply the hydrogen) ion concentration (molarity), one of the easiest properties of the solution to determine is its pH. The pH of a solution indicates the acidity (or basicity) of a given solution. The typical pH range of solutions is from 1 to 14, with 7 being neutral, 1 to 6 being acidic, and 8 to 14 being basic.

To determine the pH of a solution, the negative log (-log) of the hydronium/hydrogen ion concentration (molarity) of the solution is calculated. Thus (assuming that the given hydrogen ion concentration is in molarity (mol/L)),

pH = -log( $H^{+}$ ) or -log( $H_{3} O^{+}$
pH = -log (<span>7.94 × 10−6 mol/L)
pH = 5.13

Because the pH is less than 7 (within the range 1 to 6), then the black coffee solution is acidic. </span>
