Answer:
0.075 moles of EDTA are left.
Explanation:
To solve this problem we need to use the definition of Molar concentration (M):
M=
With that equation in mind, in the problem we're given two out of the three factors: Concentration and Volume. We're asked to calculate the remaining factor.
Before we calculate we convert 150 mL to L, so we divide 150 by 1000.
Lastly we calculate the number of moles of EDTA left:
0.5 M * 0.150 L = 0.075 moles.
Answer:
Explanation:
Rising carbon dioxide concentrations are already causing the planet to heat up. At the same time that greenhouse gases have been increasing, average global temperatures have risen 0.8 degrees Celsius
The polar covalent bonding occurs when two atoms with different electronegativity form a covalent bond. This type of connection, the electrons are not equally shared. Typically, the atom having higher electronegativity attracts the electrons in the next link to it, thus forming a negative pole in its vicinity, and a positive pole of the next region less electronegative atom.
example: In the molecule HCl, hydrochloric acid, chlorine atom is more electronegative attracting electrons proximity to the bond with the hydrogen atom that is less electronegative, or more electropositive also rated.

During all chemical reactions, the mass of the products is never equal to the mass of the reactants.
- FALSE
Mass is sometimes lost in chemical reactions.
- FALSE
The Law of Conservation of Mass states that mass is not conserved.
- FALSE
