Answer:
0.58 atm
Explanation:
Step 1: Given data
- Total pressure of the gaseous mixture (P): 1.05 atm
- Partial pressure of N₂ (pN₂): 0.35 atm
- Partial pressure of H₂ (pH₂): 0.12 atm
- Partial pressure of CO₂ (pCO₂): ?
Step 2: Calculate the partial pressure of CO₂
The total pressure of the gaseous mixture is equal to the sum of the partial pressures of the individual gases.
P = pN₂ + pO₂ + pCO₂
pCO₂ = P - pN₂ - pO₂
pCO₂ = 1.05 atm - 0.35 atm - 0.12 atm = 0.58 atm
Answer:
The correct answer is c. adding a catalyst for the reaction
Explanation:
The function of a catalyst in a chemical reactionis to increase the rate of reaction by decreasing the required activation energy which is clearly illustrated on energy diagrams. It is not consumed in the reaction and can be reused repeatedly,as such, only small quantities of catalysts are required in the reaction. Catalyst provide a separate route for a chemical reaction to proceed at a lower activation energy than an uncatalysed reaction
The process of speeding up a chemicals reaction by the addition of a catalyst is known as catalysis
Answer:
what do u need help with?
Explanation:
Answer:
D. protons that is the answer
The best way to accurately determine the pair with the highest electronegativity difference is by using their corresponding electronegativity values. For the each of the choices, the difference is:
A. H-S = 2.5 - 2.1 = 0.4
B. H-Cl = 3 - 2.1 = 0.9
C. N-H = 3 - 2.1 = 0.9
D. O-H = 3.5 - 2.1 = 1.4
E. C-H = 2.5 - 2.1 = 0.4
As show, D. has the highest difference. Without looking at their values, you can also determine the pair with the highest difference by taking note of the trend of electronegativity on the periodic table. Electronegativity increases as you go right a group and up a period. This makes oxygen the most electronegative element among the other elements paired with hydrogen.
