To balance it, it would be N2 + 3H2 ------> 2NH3.
for c) it would be 2N2 + 6H2 -------> 4NH3
Explanation:
Also, the water molecules are not changed when sugar is dissolved in water to form a sugar solution. We can easily get back the sugar by evaporation of water from the sugar solution. The evaporated water can then be condensed to recover the water also. Hence, it is a physical change and not a chemical change.
Explanation:
it's one mole because the atomic mass is treated as molar mass and the atomic mass of strontium is 87.62 grams/mol
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, by stoichiometry, the limiting reagent is computed by comparing the available moles of silicon dioxide and the consumed moles of silicon dioxide by graphite as shown below:
In such a way, since there will be less available silicon dioxide, it is the limiting reagent, therefore, the grams of silicon carbide, turns out:
Best regards.
