Alkali metals is chemicals elements found In the Periodic tables Alkali metals have included Sodium Potassium Rubidium Cesium And Francium as for Earth metals they are beryllium magnesium calcium strontium barium and radium.
To find the experimental value I believe we add up all the temperatures found by each trial and divide by the number of trials
When added up and divided up this is 50.7 C
Then we continue with accepted value minus experimental value over accepted
53.0 - 50.7 / 53.0 x 100
4.3% percent error
<span>In determining significant figure, always remember the rules:
Zeros place in the beginning and end of a non-zero numbers are not significant
Zeros place in the middle of a non-zero numbers are considered significant.
Therefore, 340 438 grams has 6
significant figures.</span>
Answer:
The answer to your question is: 0.015 mole of NO
Explanation:
Data
Silver = Ag = 0.1 mole
Nitric acid = HNO3 = 10 ml 6 M
Balanced reaction
3Ag + 4HNO₃ ⇒ 3AgNO₃ + NO + 2H₂O
# moles of HNO₃ = 6(0.01) = 0.06
Limiting reactant HNO₃ because for the amount of silver given
the reaction needs 0.133 moles of acid, and there
are only 0.06
4 mol of HNO₃ ------------------- 1 mol of NO
0.06 mol of Ag ------------------ x
x = (0.06 x 1) / 4
x = 0.015 mol
