The major concern for the Union government offices during the war was that the Confederate states managed to win a battle in very close proximity to their capital Washington. The fact that the Confederate forces were so close to Washington, and the defenses of the capital were very strong at the moment, while the majority of the soldiers were at other locations and needed time to get back to defend it. This was bringing a big concern because if Washington was captured by the Confederate forces then the Union would have been in big trouble and suffer badly because of it.
Answer:
A. For every mole of carbon dioxide consumed, one mole of water is consumed
Explanation:
The photosynthetic equation is given as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
The coefficient in front of each reactant and product is used to represent the number of moles needed for each compound/element in the reaction.
Based on this, this means that 6 moles of CO2 (carbon dioxide) needs to react with 6 moles of H2O (water) to form the products.
In a simpler form, this also means that for every 1 mole of carbon dioxide (CO2) consumed, one (1) mole of water (H2O) is consumed.
Answer:
1: At temperatures below 542.55 K
2: At temperatures above 660 K
Explanation:
Hello there!
In this case, according to the thermodynamic definition of the Gibbs free energy, it is possible to write the following expression:
Whereas ΔG=0 for the spontaneous transition. In such a way, we proceed as follows:
1:
It means that at temperatures lower than 542.55 K the reaction will be spontaneous.
2:
It means that at temperatures higher than 660 K the reaction will be spontaneous.
Best regards!
Answer:
Explanation:
We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 16.04 32.00 44.01 18.02
CH₄ + 2O₂ → CO₂ + 2H₂O
m/g: 10.0 40.0
1. Moles of CH₄
2. Mass of CO₂
(i) Calculate the moles of CO₂
The molar ratio is (1 mol CO₂ /1 mol CH₄)
(ii) Calculate the mass of CO₂
3. Mass of H₂O
(i) Calculate the moles of H₂O
The molar ratio is (2 mol H₂O /1 mol CH₄)
(ii) Calculate the mass of H₂O
