Answer:
Increasing the concentration of A will cause the greatest change over the rate.
Explanation:
Hello,
In this case, considering the given rate law, which is third-order with respect to A, changing its concentration, the rate will be significantly modified. For instance, suppose a concentration of A and B of 1M and a symbolic rate constant (k), this causes the rate to be:
Then, if we change the concentration of A to 2 M holding the concentration of B in 1 M, the new rate constant will be:
Nevertheless, if we hold the concentration of A in 1 M and the concentration of B is now 2 M (same change), the new rate constant is:
It means that increasing the concentration of A will cause the greatest change over the rate.
Best regards.
Answer:
Calcium + Oxygen = Calcium Oxide
Explanation:
Calcium basics: -positively charged ion (cation) -99% in bones and teeth, 1% in extracellular fluid. -important for bone and tooth formation, normal cell function, and neural transmission.
Oxygen, a colourless, odourless, tasteless gas essential to living organisms. It will support life. It is noncombustible, but will actively support the burning of combustible
Symbol: O
Atomic mass: 15.999 u
Atomic number: 8
Electron configuration: [He] 2s²2p⁴
Electrons per shell: 2, 6
Melting point: -218.8 °C
Calcium reacts with oxygen to form calcium oxide. The chemical equation for this reaction is Ca + O2 → CaO.
Answer:
The correct answer is 28.2 %.
Explanation:
Based on the given question, the partial pressures of the gases present in the trimix blend is 55 atm oxygen, 50 atm helium, and 90 atm nitrogen. Therefore, the sum of the partial pressure of gases present in the blend is,
Ptotal = PO2 + PN2 + PHe
= 55 + 90 + 50
= 195 atm
The percent volume of each gas in the trimix blend can be determined by using the Amagat's law of additive volume, that is, %Vx = (Px/Ptot) * 100
Here Px is the partial pressure of the gas, Ptot is the total pressure and % is the volume of the gas. Now,
%VO2 = (55/195) * 100 = 28.2%
%VN2 = (90/195) * 100 = 46%
%VHe = (50/195) * 100 = 25.64%
Hence, the percent oxygen by volume present in the blend is 28.2 %.
Answer:
The answer is
<h2>1.33 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 3.46 g
density = 2.60 g/cm³
The volume is
We have the final answer as
<h3>1.33 cm³</h3>
