Answer:
Standard boiling point
Explanation:
Note that there are 2 major units of pressure except Pa .
- bar
- atm
At 1 atm pressure the boiling temperature is called normal boiling point.
At 1 bar pressure the boiling temperature is called standard boiling point
Answer:
32.92 moles of Mg
Explanation:
To convert grams to moles (Or vice versa) of any chemical compound we need to use the molar mass of the substance (That is, how many grams weighs 1 mole of the chemical).
The magnesium, Mg, has a molar mass of 24.305g/mol. That means in 800.0g of Mg you have:
800.0g * (1mol / 24.305g) =
<h3>32.92 moles of Mg</h3>
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."
I don't actually know this is a guess and this is false
