Product of this reaction depends on the amount of oxygen.
i.) If oxygen is excess:
Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2
Equation :
C + O2 ----> CO2. This reaction is also called combustion reaction. The expensive way to produce CO2 is to burn Diamond in the presence of air at 600-800°C. Hope it helped you. :D
Answer:
1. 23.3 g
2. 82 g
3. 0.402 mol
4. 0.506 mol
Explanation:
We can convert moles (n) to mass (m) using the following expressions that include the molar mass (M).
n = m/M
m = n × M
1. The molar mass of NH₄Cl is 53.49 g/mol.
m = 0.436 mol × 53.49 g/mol = 23.3 g
2. The molar mass of Ca(NO₃)₂ is 164.09 g/mol.
m = 0.50 mol × 164.09 g/mol = 82 g
3. The molar mass of NaCl is 58.44 g/mol.
n = 23.5 g/(58.44 g/mol) = 0.402 mol
4. The molar mass of KMnO₄ is 158.03 g/mol.
n = 79.9 g/(158.03 g/mol) = 0.506 mol
Answer:
Explanation:
Hello!
In this case, we need to keep in mind that performing these types of operations require that the final result was shown with the same significant figures as the initial number with the fewest ones; it means, we show the final result with 3 significant figures, because 3.698 has four and 1.85 has three significant figures; therefore, we obtain:
Best regards!
The atoms in a metal form a matrix in which their outer electrons can move freely.
