<span>Answer: option (3) energy, charge and mass.
</span><span />
<span>Explanation:
</span><span />
<span>1) The conservation of energy is a universal principle: energy is neither created nor destroyed. This is the first law of thermodynamic.
</span><span />
<span>2) Mass conservation is another universal principle: mass is neither created nor destroyed. This principle is the base of the stochiometry: thas mass of the reactans equal the mass of the products. Another consequence, since the atoms are not transformed in the chemical reactions, is that the number of each kind of atoms in the reactants equal the number of the same kind of atoms in the products.
</span><span />
<span>3) The third principle is the conservation of charge. Also, charge is neither created nor destroyed. The electrons gained/lost by one species are lost/gained by other species. So, when one atom or molecule is oxidized other is reduced.</span>
The lowest point of a wave is called trough.
To determine the number or amount of carbon dioxide produced from the equation, we have to note from the given chemical reaction that the ratios of the moles of the participating reactants and the resulting products will be obtained.
The first step to answering this item is to determine the number of moles of CH4 by dividing the given amount in grams by the molar mass. Molar mass of methane, CH4, is equal to 16 g/mol.
The first conversion factor is therefore is 16 g/mol.
Answer: 1/12
1/4 divided by 3/1
KCF:Keep the first fraction, Change the sign to muplication, Flip the second fraction.
1/4* 31
1*1=1
4*3=12
1/12
