2.5 % w/v ( that means we have 2.5 grams of solute in 100 mL <span>solution )
1.00 mL = 1000 mL therefore:
2.5 g ------------- 100 mL
?? --------------- 1000 mL
1000 x 2.5 / 100 => 25.0 g of NaCl</span>
Cosmic microwave background radiation (CMBR) is one piece of evidence for the big bang
There is 3 electrons at the outer layer of the Al atom. So when the valence electrons were removed and Al ion at a stable status, the Al ion is +3 charge.
Answer:
The reaction is:
H⁺
CaCO₃ ⇄ Ca²⁺ + CO₃ ⇄ HCO₃
The standard free energy change is ΔG = ΔH - TΔS
Explanation:
Limestone is a mineral familiar with calcium carbonate, and being very common, the acid present in acid rain dissolves it reacting with carbonate, since the acids present in acid rain are characterized by being highly soluble in water and are also strong acids. The reaction is as follows:
H⁺
CaCO₃ ⇄ Ca²⁺ + CO₃ ⇄ HCO₃
The spontaneity of the reaction is equal to:
ΔG = ΔH - TΔS
The sign of the standard free energy changes from positive to negative.
Based on our finding these two compounds are not same they are completely different from each other as Formula of both compounds are different, their appearance is also different from each other.
<h3>What is Iron (II) Oxide ? </h3>
The formula of the Iron II oxide is FeO. Common name of Iron (II) Oxide is Ferrous Oxide. Iron (II) Oxide is a black colored powder. The mineral form of Iron (II) oxide is known as Wustite. Iron (II) Oxide is used as a pigment. It is also used to make dyes.
<h3>What is Iron (III) Oxide ? </h3>
The formula of the Iron (III) Oxide is Fe₂O₃. Common name of Iron (III) Oxide is Ferric oxide. Iron (III) Oxide appears as Red-Brown solid. It is also known as Hematite. Iron (III) oxide is used as pigments. It is used in dental composites , cosmetics. It is also used to apply the final polish on metallic jewellery.
Thus from the above conclusion we can say that Based on our finding these two compounds are not same they are completely different from each other as Formula of both compounds are different, their appearance is also different from each other.
