Asnwer :When 1 molecule of calcium phosphate is added to water, total 5 ions are formed 3 ions of Calcium(Ca^{2+}) and 2 ions of Phosphate(PO_{4}^{3-})

Explanation : When Calcium phosphate is added to water it gets dissociated into ions. Calcium phosphate (Ca_{3}(PO_{4})_{2}) dissociates into 3 ions of Calcium Ca^{2+} and 2 ions of Phosphate PO_{4}^{3-}.

Dissociation equation of calcium phosphate is :

1 Ca_{3}(PO_{4})_{2} \leftrightarrow 3 Ca^{2+} + 2PO_{4}^{3-}

From the dissociation equation we can conclude that total 5 ions are formed when 1 molecule of calcium phosphate is added to water.

Magnesium chloride is a salt formed with ionic bonds between one magnesium ion and two chloride ions. Magnesium has two electron
katrin [286]

Answer:

The magnesium atom loses 2 electron to the 2 atoms of chlorine. The 7 valency electrons of each chlorine atom will now be 8 to attain stable configuration. The final compound is written as MgCl2.

Explanation:

Ionic compounds are compound formed from the transfer of electron(s). One atom of the element loses electron(s) while the other atom gains electron(s).

The compound Magnesium chloride is an ionic compound . The bond between an atom of magnesium and 2 atoms of chlorine is an ionic bonding.

The valency electron of magnesium is 2 electron , for the atom of magnesium to  attain octet rule, it will easily lose it 2 electrons to the chlorine atoms.

The chlorine atom on the other hand has 7 valency electrons, to attain octet configuration it will most likely gain 1 electron to become stable.

The magnesium atom loses 2 electron to the 2 atoms of chlorine. The 7 valency electrons of each chlorine atom will now be 8 to attain stable configuration. The final compound is written as MgCl2.

a pure substance that cannot be broken down into any other substances by chemicals or physical mean is a
Nat2105 [25]
It is a element.

Pure substances includes either compunds, or elements. Elements are the simplest form of pure substance, they only consist of one kind of atoms. On the other hand, compounds contains two or more elements that are chemically combined together. Although you couldn't separate a compound by physical methods like filtration, but you can seperate them with chemical methods such as heating or electrolysis, using electricity.

Therefore, since compounds can be broken down eventually, so, the answer will be element.

For a specific enzyme/substrate system, which condition will always result in an increase in Vo (assuming nothing else changes)?
inessss [21]
<span>a decrease in Km and an increase in Vmax
 km is the constant that relates how thick the volume of the substrate in terms of concentration when the speed is a large portion of the most extreme. They increment Km by meddling with the joining process that makes them stick together wit the substrate, however they have any effect with regards to Vmax since since the sticking process to ES did not occur</span>

How many electrons would be in a calcium cation with a positive 2 charge?
kondor19780726 [428]

Number of electrons in a Ca²⁺ = 18

<h3>Further explanation  </h3>

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is  

• s: 2 electrons  

• p: 6 electrons  

• d: 10 electrons and  

• f: 14 electrons  

Charging electrons in the sub shell uses the following sequence:  

<em>1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  </em>

The element Ca has an atomic number of 20, so the number of electrons and protons (in neutral atoms) is also 20

Electron configuration of Ca : <em>1s², 2s², 2p⁶, 3s², 3p⁶, 4s² ⇒[Ar] 4s²</em>

When Ca releases 2 electrons to gain stability (forming Ca²⁺ cations), the number of electrons becomes:

\tt 20-2 = 18

and the electron configuration (Ca²⁺ ) becomes:

<em>1s², 2s², 2p⁶, 3s², 3p⁶</em>
