Answer:
Percent error = 2.8
Explanation:
Given data;
Actual value = 17.9 cm
Measured value = 17.4 cm
Percent error = ?
Solution:
Formula:
Percent error = [actual value - measured value / actual value] × 100
Now we will put the values in formula:
Percent error = [17.9 cm - 17.4 cm / 17.9 cm] × 100
Percent error = [0.5 cm /17.9 cm] × 100
Percent error = 0.028 × 100
Percent error = 2.8
Bonds formed between atoms can be classified as ionic and covalent
Ionic bonds are formed between atoms that have a high difference in the electronegativity values.
In contrast, bonds formed between atoms that have a difference in electronegativity lower than the ionic counterparts are polar covalent bonds. If the atoms have very similar electronegativities, they form non-polar covalent bonds.
In H2S, the S atom is bonded to 2 H atoms. The electronegativity of H = 2.2 and S= 2.56. Since the difference is not high the bond formed will be covalent (polar covalent).
Answer: The amount of coffee is the same
Explanation: This was the correct answer for me.
I think your answer would be an Atom because it is referred to as the smallest unit of matter that retains the chemical properties of an element.
