Just do 0.02 * 4 and you get 0.08 ml or 80 microliter
Answer:
179 L of CO2
Explanation:
Given the equation of the reaction;
C2H6(g) + 7/2 O2(g) -------> 2CO2(g) + 3H2O(g)
Now 1 mole of ethane yields 2 moles of CO2 from the balanced reaction equation
1 mole of a gas occupies 22.4 L volume so,
22.4 L of ethane yields 44.8 L of CO2
89.5 L of ethane yields 89.5 * 44.8/22.4 = 179 L of CO2
Answer:
<h2>The answer is 2.5 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of object = 10.02 g
density = 4.08 g/mL
The volume of the object is
We have the final answer as
<h3>2.5 mL to one decimal place</h3>

Answer:
elliptical/ellipse
Explanation:
» <u>Concepts</u>
Astronomer <u>Johannes Kepler</u> discovered and founded his three laws of planetary motion. One of these laws states that the orbit of <u>all</u> planets, including Earth, is in an elliptical shape rather than a circle.
Since this has to do with titration, the measured volume of NaOH used would be less than the actual volume used because some of the unused NaOH would cling to the sides of the buret and therefore wouldn't factor into the measurement
Hope this helps
