Answer:
a. C5H12 + O2 → CO2 + H2O
c) Mg + O2 → MgO
Explanation:
Una reacción de combustión es definida como una reacción en la que un elemento o compuesto reacciona con oxígeno para producir un óxido y liberar calor.
Cuando un hidrocarburo (De fórmula general CₓHₙ) entra en combustión, dióxido de carbono y agua son producidos.
Así, las reacciones que corresponden a combustión son:
a. C5H12 + O2 → CO2 + H2O
<em>Se produce dióxido de carbono y agua</em>
c) Mg + O2 → MgO
<em>Se produce óxido de magnesio y se libera calor.</em>

Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.
<span>The electrical charge of the hydrogen atom is thought to be exactly zero. This is a consequence of the apparent equality of the magnitude of the electrical charges of the electron and the proton, and their opposite sign.</span>
Answer:
The density of tube A is greater then the density of tube B having more mass inside of the smaller area.
Explanation:
Answer:
When you balance a chemical equation, you change coefficients. You never change subscripts. A coefficient is a whole number multiplier. To balance a chemical equation, you add these whole number multipliers (coefficients) to make sure that there are the same number of atoms on each side of the arrow.
