At STP (standard temperature and pressure conditions), 1 mol of any gas occupies 22.4 L
This rule is applied to O₂
22.4 L volume occupied by 1 mol
Therefore 83.4 L occupied by - 1/ 22.4 x 83.4 = 3.72 mol
stoichiometry of O₂ to H₂O is 1:2
then the number of moles of water produced - 3.72 mol x 2= 7.44 mol
mass of water produced - 7.44 mol x 18.01 g/mol = 134.1 g
correct answer is D
Answer: The water (in a subtle sort of way) will now be attracted towards the balloon
I attached a picture to help make sense
A digital thermometer has less errors in reading temperatures because it displays the actual reading rather than approximating it in a liquid-based thermometer. Also, digital thermometer are advantageous to use in extreme temperature conditions because they can withstand in these type of conditions.
Oxygen is Earth's most abundant element by volume in Earth's Orbit
Answer:
By presenting the results in a poster session.
Explanation:
Several scientists from different countries are asked to examine the results of an experiment before a journal will print it.
