Answer:
11.3 g.
Explanation:
Hello there!
In this case, since the combustion of butane is:
Thus, since there is a 1:5 mole ratio between butane and water, we obtain the following mass of water:
Therefore, the resulting mass of water is:
Best regards!
Answer:
the NaCl is not considered a molecula
Explanation:
Sodium atoms, (Na +) and chlorine atoms, (Cl-) form a three-dimensional network. The cations and the anions are joined together by electrostatic attraction which we call ionic bonding
Molecules are atoms bound with chemical bond.
The answer should be 2) electrons.
The elements in the periodic table are arranged by increasing atomic number, which is also the number of protons in an element. For example, Carbon has 6 protons, it is the sixth element on the table. While Nitrogen, which has 7 protons, is after Carbon.
In atoms, the number of protons equals to the number of electrons too, if the number of electrons does not equal to the number of protons, the substance is no longer atom, but ion. So, the answer to this is 2) electrons, as the elements on the table is arranged according to increasing atomic numbers.
