Answer:
v2=4.735L
Explanation:
using charles law
v1\t1 = v2\t2
v1= 4.5L
t1= 14+273= 287K ( temperature has to be in kelvins)
t2=29+273= 302K
v2=?
by substitution;
4.5\287 = v2\302
v2=(302 x 4.5)\287
v2=4.735L
The substance that can act as an Arrhenius base in aqueous solution is sodium hydroxide since NaOH dissociates in water giving the sodium ions and the hydroxide ions. An Arrhenius base is a substance that is characterized by forming hydroxide ions in an aqueous solution.
Answer:
Theoretical yield = 3.75g
Explanation:
Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:
Percent yield = Actual Yield / Theoretical Yield * 100
In the problem, your actual yield was 3-00g.
Percent yield is 80.0%.
Solving for theoretical yield:
80% = 3.00g / Theoretical yield * 100
Theoretical yield = 3.00g / 80.0% * 100
<h3>Theoretical yield = 3.75g</h3>
Answer:
7 grams
Explanation:
The water evaporates leaving the same amount of salt behind
