Answer:it becomes positively charged
Explanation:Some atoms can attract additional electrons so they become negatively charged.
Answer:
Actual yield = 20.52 g
Explanation:
Given data:
Theoretical yield = 25.3 g
Percentage yield = 81.1 %
Actual yield = ?
Solution:
Formula:
Percentage yield = Actual yield /theoretical yield × 100
81.1 % /100 = Actual yield / 25.3 g
0.811 = Actual yield / 25.3 g
Actual yield = 0.811 × 25.3 g
Actual yield = 20.52 g
Answer:
0.98 g of H₂
Explanation:
the balanced equation for the reaction is
Mg + 2HCl ---> MgCl₂ + H₂
molar ratio of Mg to H₂ is 1:1
number of Mg moles reacted = 12 g/ 24.3 g/mol = 0.49 mol
according to molar ratio
when 1 mol of Mg reacts 1 mol of H₂ is formed
therefore when 0.49 mol of Mg reacts - 0.49 mol of H₂ forms
therefore mass of H₂ formed = 0.49 mol x 2 g/mol = 0.98 g
mass of H₂ formed is 0.98 g
Answer: I'm in no way like an expert but I've heard water goes from an elevated area to a lower area. So it should be arrows that start at a more elevated to less elevated. Like white to brown, and orange to yellow, and stuff like that. I hope that helped? Anyway, have a lovely day!
