They emit radiation. Which can be very harmful to living things, as well as some non living things. I hope i answered you question :)
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
The molecule is thiophosgene or CSCl₂.
<h3><u>Explanation:</u></h3>
As the informations given, the molecule contains 12.17 grams of carbon, 32.53 g of sulfur, and 72.19 g of chlorine.
Molar mass of carbon =12.
Molar mass of sulphur =32.
Molar mass of chlorine =35.
So on an average estimation, one mole of the molecule contains one mole of carbon atoms, one mole of Sulphur atoms and two moles of chlorine atoms. Molar mass of an element is the average weight of one mole of atoms of that element which is made average according to the variations of percentage availability of isotopes of that element on earth.
So the estimated molecule is CSCl₂ or thiophosgene.
Yes just like with sugar and water temperature affects the process and warmer water causes faster dissolution.
