Answer:
86% is the percent yield of the reaction
Explanation:
Percent yield is defined as 100 times the ratio of actual yield / theoretical yield.
Based on the reaction:
2Na + Cl₂ → 2NaCl
The theoretical yield is 0.50 moles because 0.50 mol of Na are added in the beginning. As 0.43 moles are produced, actual yield is 0.43 mol. And percent yield is:
0.43mol / 0.50mol * 100 =
<h3>86% is the percent yield of the reaction</h3>
PLA is a type of condensation polymer. Hydroxyl group of one lactic acid reacts with carboxylic group of second lactic acid and a ester is formed with the elimination of water molecule. And the reaction propagates with the increase in chain. And, the product formed is PLA as shown below.
Answer:
I'm pretty sure that it's plate movement...
Answer: 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of 
Explanation:
The balanced decomposition reaction is shown as

moles of 
According to stoichiometry:
2 moles of
gives = 3 moles of flourine gas
Thus 0.36 moles of
gives =
of flourine gas
Using ideal gas equation :

P = pressure of gas = 1 atm ( at STP)
V = Volume of gas = ?
n = moles of gas = 0.54
R = gas constant = 0.0821 L atm/Kmol
T = temperature = 273 K ( at STP)
Putting the values we get :


Thus 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of
