Answer:
B. accepted value x 0.1
Explanation:
in the equation provided
Maximum allowed value of percentage error = 10%
put this value in the equation in stead of percentage error we get,
so maximum error = .1 x accepted value
10 % percentage error means the experimental value has 10 % error compared to accepted value.so error will be 10 % of the accepted value
or .1 times of accepted value
Answer:
The chemical formula for rust is Fe2O3. Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3.
Explanation:
wavelenghts are lengths. they are measured in distances.
Answer:
Covalent bonds
Explanation:
There are about three kinds of bonds in chemistry;
Ionic bonds
Covalent bonds
Metallic bonds
Substances that possess ionic and metallic bonds all have high melting and boiling points.
However, covalent molecules often have low melting and boiling points due to weak intermolecular forces in the solid state. They also have a dull appearance and do not dissolve in water.
