Answer:
A. Feels slippery
Explanation:
Bases are the only types of compounds that have a slippery feel.
B is <em>wrong</em><em>.</em> Most bases do not contain carbon, but organic compounds always do.
C is <em>wrong</em>. Aqueous solutions of bases conduct electricity, but so do aqueous solutions of salts.
D is <em>wrong</em>. Most bases have a bitter taste. Acids have a sour taste.
D. none of these will increase the mass
Water is an example of a balanced synthesis equation: 2 H2(g) + O2(g) → 2 H2O(g). The number of atoms in the reactants and the number of atoms in the products must balance in a chemical equation.
<h3>What is balanced equation?</h3>
A chemical reaction equation is said to be balanced if both the reactants and the products have the same total charge and the same number of atoms in the reaction. In other words, both sides of the reaction have an equal mass and charge balance.
The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction. On the left and right sides of a balanced chemical equation, there are an equal number of atoms of each element.
Therefore,
Water: 2 H2(g) + O2(g) → 2 H2O(g)
2K + 2H2O → 2KOH + H.
NaCN ( a q ) + HBr ( a q ) → NaBr ( a q ) + HCN ( g )
2HgO(s)→2Hg(l)+O2(g)
2CH3OH + 3O2 → 4H2O + 2CO2
HCl(aq)+NaOH(aq)⇌NaCl(aq)+H2O
