Answer:
Explanation:
Hello there!
in this case, according to the given information, it turns out firstly necessary for us to write up the chemical equation as shown below:
Thus, we calculate the mass of BaCl2 stoichiometrically related to the produced 1.658 g of precipitate in order to discard it from the sample:
Thus, the mass percentage is calculated as shown below:
Regards!
PbO2
You have to take the mass of lead in the problem, and divide by the molar mass.
When you do the same with oxygen, you get a number about twice as large as when you divide the mass of lead by the molar mass of lead. This means that the simplest formula would be PbO2
The answer is C2H2 because an alkyne compound consists of a series of unsaturated hydrocarbons with a triple bond.
1) C
2) B
3) A/B not sure
4) C I think
C plasmas have a net negative charge
