Answer:
Explanation:
Using the ideal gas equation as follows:
PV = nRT
Where:
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
Based on the information provided in this question;
P = 1.6atm
n = 4.4 moles
R = 0.0821 L*atm/mol*K
T = 32.9°C = 32.9 + 273 = 305.9K
V = ?
Water is amphoteric with both the acidic and basic characters.
<u>Explanation:</u>
As per the Bronsted Lowry theory of acids and bases,
Water has its own ability to either donate or accept hydrogen ions or protons.
- If it accepts a proton then it is termed as basic
- To accept a proton it should have a lone pair of electrons.
- If it donates a proton then it is termed as acidic
- If the water has the ability to accept as well as donating proton then it has both the acidic and basic characters and so it is termed as amphoteric in nature.
Moles of Oxygen they took in : C. 2.42
<h3>Further explanation</h3>
The gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 l.atm / mol K
T = temperature, Kelvin
P=1000 kPa
V = 6 L
T = 298 K
moles of Oxygen :
Answer:
Boron has a larger radius and the protons in carbon exert more pull.
Explanation:
Remember than elements have greater radius as they are closer to the bottom left corner, so boron would have the larger radius here. Carbon has a smaller radius, which makes it easier for the protons in carbon to exert more pull.
The logical hypothesis for the observed data could be something like :
The reason of the difference in optimal Ph between the experiments could be caused by the Enzyme extract of the different enzymatic forms of the Radish Sprouts , causing different level of Ph
