Answer:
T₂ = 464.75 K
Explanation:
Given data:
Initial Temperature = 398.15 K
Pressure = 248 torr (constant)
Initial Volume = 275 mL (275/1000 = 0.275 L)
Final volume = 0.321 L
Final temperature = ?
Solution:
V₁/T₁ = V₂/T₂
T₂ = V₂ T₁ / V₁
T₂ = 0.321 L × 398.15 K / 0.275 L
T₂ = 127.81 L.K / 0.275 L
T₂ = 464.75 K
Answer:
Be the anode
Explanation:
The standard hydrogen electrode is regarded as the standard reference electrode and it has been assigned an electrode potential of 0.0V.
If any substance has an electrode potential that is more negative than hydrogen, then that half cell will function as the anode when connected to the standard hydrogen electrode.
Similarly, any substance that has a more positive electrode potential than hydrogen will serve as the cathode when its half cell is connected to the standard hydrogen electrode.
Answer:- The weight of the arrow is 0.75 ounces.
Solution:- It is a unit conversion problem where we are asked to convert grains to ounces. We could easily do this conversion using two steps conversion, grains to pounds and pounds to ounces.
We know that, 1 pound = 7000 grains
1 pound = 16 ounces
Let's make the set up to convert 330 grains to ounces as:
= 0.75 ounces
So, the weight of 330 grains of arrow in ounces is 0.75.
