Answer:
Percent error = - 8.1 %
Explanation:
Given data:
Actual mass = 27.20 g
Theoretical mass = 25.01 g
Percent error = ?
Solution:
Formula:
Percent error = theoretical value- actual value/ actual value × 100
Now we will put the values in formula.
Percent error = 25.01 - 27.2 / 27.2 × 100
Percent error = -2.19 / 27.2 × 100
Percent error = -0.081 × 100
Percent error = - 8.1 %
Answer:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Explanation:
They have 6 valance electrons.
The correct answer is Be+
That is because it lost a single electron but still has the same number of protons, and thus the effective charge attracting each electron is greater, which in turn makes the radius even smaller
