Answer:
because they cannot keep their body temperature constant.
Answer:
1.25 moles of tungsten carbide
Explanation:
Tungsten carbide, WC, is a substance that is produced prom carbon and tungsten as follows:
W + C → WC
Based on the reaction, 1 mole of Carbon produce 1 mole of tungsten carbide. That means if 1.25 moles of carbon are added in excess of tungsten, the moles of tungsten carbide produced are:
<h3>1.25 moles of tungsten carbide</h3>
Answer:
The number of atoms in the reactants equals the number of atoms in the products.
Explanation:
In every chemical reaction equation there are two sides; the reactants sides and the products side. The reactants side shows the species that combine to form the products. On both sides of the reaction equation, chemical species are found to be composed of atoms.
The major principle in balancing of chemical reaction equations is that the number of atoms of each element in the reactants side must be equal to the number of atoms of the same element on the products side. Once this condition is achieved, we can now say that the chemical equation is balanced.
