Answer:
c)
more hydronium ions than chloride ions
The reaction, 2 C4H10 (g) + 13 O2 (g) = 8 CO2 (g) + 5 H2O (g), is the combustion of butane. A combustion reaction involves the reaction of a hydrocarbon with oxygen producing carbon dioxide and water. This reaction is exothermic which means it releases energy in the form of heat. Therefore, as the reaction proceeds,a heat energy is being given off by the reaction. This happens because the total kinetic energy of the reactants is greater than the total kinetic energy of the products. So, the excess energy should be given off somewhere which in this case is released as heat.
Is molecule an answer? It wouldn't let me see all the answers. if it is, molecule is the correct answer. they are held together by a covalent bond, I believe.
Answer:
A. 11
Explanation:
atoms are made of three types of sub atomic particles - protons, neutrons and electrons
Protons are positively charged, electrons are negatively charged and neutrons are neutral.
Protons and neutrons are located inside the nucleus and electrons orbit around the nucleus in energy shells.
Atoms make up an element and atoms are neutral charged with an equal number of protons and electrons. Neutral atom of sodium would therefore have an equal number of positive charges and negative charges.
Since Na has 11 protons, for it to be neutral it would have 11 electrons
