When cells of plants and animals break down food they produce energy and when fossils fuel such as coal and gaseline are burned
Answer: H2O
Explanation:
The strongest hydrogen bond type is the one involving a bond between oxygen, nitrogen and fluorine, with a hydrogen atom. Since in the choices, only water shows a O-H bond, therefore this is the strongest hydrogen bonding. The answer is water.
Neutrons.
Electrons have little to no mass, therefore shouldn't be electrons.
Also there is only eight protons in this atom, while there are nine neutrons.
The balanced chemical equation for aqueous sodium hydroxide being added to a solution containing lead(II) nitrate and a solid precipitate being formed is :
2 NaOH (aq) + Pb(NO3)₂ (aq) ⇒ Pb(OH)₂ (s) + 2 NaNO₃ (aq)
A balanced chemical equation is the one in which the number of atoms are equal for every element on both the the reactant side as well as the product side. Their charges should also be the same.
A precipitate is a solid mass of some substance that forms up in a liquid solution due to certain chemical reactions. This solid mass does not dissolve in the liquid solution.
