Answer:
Percent error = 1.5%
Explanation:
Given data:
Measured value of density of graphite = 2.3 g/cm³
Percent error = ?
Solution:
Formula:
Percent error = [Measured value - Actual value / actual value] × 100
Actual/accepted value of density of graphite = 2.266 g/cm³
Now we will put the values:
Percent error = [2.3 g/cm³ - 2.266 g/cm³ / 2.266 g/cm³] × 100
Percent error = [0.034 g/cm³ / 2.266 g/cm³] × 100
Percent error = 0.015 × 100
Percent error = 1.5%
Answer:
it should be 3
Explanation:
because its already above the 4th line so it wouldn't make sense to say 2 4/4
Answer:
9,500J
Explanation:
Distance= 50m
Force = 190N
Energy = Force x distance
= 190 x 50
= 9,500J
The compound that contains a multiple covalent bond in the list is C2H4.
<h3>What is a multiple covalent bond?</h3>
A multiple covalent bond is a double or triple bond. The bonds are known by multiple dashes between atoms that are covalently bonded.
Compounds that contain multiple covalent bonds do not contain the full compliment of hydrogen atoms per carbon atom. Hence, the compound that contains a multiple covalent bond is C2H4.
