Answer:
There will be produced:
2.97 moles HMnO4
4.45 moles Pb(NO3)2
2.97 moles H2O
Explanation:
Step 1: Data given
Manganese(II) oxide = MnO2
lead(IV) oxide = PbO2
nitric acid = HNO3
Moles of HNO3 = 8.90 moles
Step 2: The balanced equation
2MnO2 + 3PbO2 + 6HNO3 → 2HMnO4 + 3Pb(NO3)2 + 2H2O
Step 3: Calculate moles of reactants and products
For 2 moles MnO2 we need 3 moles PbO2 and 6 moles HNO3 to produce 2 moles HMnO4, 3 moles Pb(NO3)2 and 2 moles of water
For 8.90 moles of HNO3, there will react:
8.90 / 3 = 2.97 moles MnO2
8.90 / 2 = 4.45 moles PbO2
There will be produced:
8.90/3 = 2.97 moles HMnO4
8.90/2 = 4.45 moles Pb(NO3)2
8.90 / 3 = 2.97 moles H2O
Circumpolar constellations stay in the sky. Because of the rotation of the Earth and its orbit around the Sun, we divide the stars and constellations into two groups. Some stars & constellations never rise nor set, and they are called circumpolar.
Chemical reactions release or absorb heat or other energy or may produce a gas, odor, color change, or sound. If you don’t see any of these indications, a physical change likely occurred. Be aware a physical change may produce a dramatic change in the appearance of a substance. This doesn’t mean a chemical change occurred. Examples of a chemical change would be rusting iron, or burning wood, or even cooking. Examples of physical changes would be tearing paper, boiling water, or freezing popsicles.
The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
<h3>What is Acids ? </h3>
Acids is defined as substances that is able to donate a proton or hydrogen ion to other substance. Acids acts as proton donor.
<h3>What is Oxoacids ? </h3>
An oxoacids is an acids that contains oxygen. It is also called oxyacids or ternary acids. Oxoacids are the acids of oxoanions.
If anion name contains the suffix ‘ate’ then replace ‘ate’ with ‘ic’.
If anion name contains the suffix ‘ite’ then replace ‘ite’ with ‘ous’.
Given anion is bromite. Formula of bromite is BrO₂⁻. It is an oxoanion.
Now write the name of acid. Here anion name contains the suffix ite so replace the ‘ite’ of bromite with ‘ous’.
The name of the acid is Bromous acid.
Formula of the acid is HBrO₂.
Thus from the above conclusion we can say that The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
