The best equation which illustrate the law of conservation of mass is
Zn +2 HCl --> ZnCl2 + H2
This is because the mass of the product is equal to the mass of reactant. for example the mass of Zn is 1 in the reactant and product side. According to the law of mass conversation the mass in a isolated system is neither created nor destroyed by chemical reaction or physical transformation
Answer:
0.0063 mol
Explanation:
Step 1: Write the balanced combustion equation
C₈H₁₈(l) + 12.5 O₂(g) ⇒ 8 CO₂(g) + 9 H₂O(g)
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of C₈H₁₈ to CO₂ is 1:8.
Step 3: Calculate the number of moles of C₈H₁₈ needed to produce 0.050 moles of CO₂
0.050 mol CO₂ × 1 mol C₈H₁₈/8 mol CO₂ = 0.0063 mol C₈H₁₈
Answer:
"A statement that can be verified by an experiment"
Explanation:
A hypothesis is an idea or explanation that you then test through study and experimentation.
Answer:
Explanation:
Based on the scenario being described it seems that this is due to the later ionization energies, namely the 2nd, 3rd etc... seem to be much higher than the first. Therefore this causes an excess amount of energy to be used in order to remove the electrons, thus causing less energy to be left after the process is over. This would be the best explanation for this behavior.
