Answer:BaCl (aq)+ K2CO3 (aq)——> Ba2CO3 (aq) + KCl (aq)
Explanation:
The equation is already balanced and it is a double replacement reaction.
Answer:
Its either B or D. I personally would go with B
Explanation:
the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
Hope this helps ^^
Answer:
To make the buffer you must add 1 mole of MES in the liter of the buffer.
Explanation:
To find pH of the buffer of MES you must use Henderson-Hasselbalch equation:
pH = pKa + log [MES⁻] / [MES]
<em>Where [MES⁻] is molar concentration of unprotoned MES and [MES] molar concentration of the acid</em>
<em />
Replacing:
6.2 = 6.2 + log [1M] / [MES]
<em>Molar concentration of [MES⁻] is 1mol / L = 1M</em>
0 = log [1M] / [MES]
1 = [1M] / [MES]
[MES] = 1M
That means to make the buffer you must add 1 mole of MES in the liter of the buffer

Aluminum can be oxidized by and
<h3>What is oxidizing?</h3>
Some of the metal corrodes (or oxidizes) and forms the corresponding metal oxide on the surface as a result of a chemical reaction between the metal surface and the oxygen in the air. The corrosion products that occur in some metals, like steel, are highly apparent and loose.
According to reactivity series (The array of metals in the descending order of their reactivities is referred to as the metals' reactivity series. It is sometimes referred to as the metals in the activity series.)
Lithium and calcium ions are more reactive than aluminum ion and they are less electronegative.
Since silver and tin are more electronegative than aluminum so, they cannot oxidize aluminum.
∴ and ions can oxidize aluminum.
