30% should be the percentage of oxygen if the total mass of fe2o3 is 160.
A weak Bronsted-Lowry base is a weak proton acceptor, where the proton is in the form of H+, so the conjugate acid formed contains one more H atom and an extra positive charge.
Hope this helps!
Answer:
the acceleration is 3 k/h/s
Explanation:
The formula for acceleration is Δv/t, so change in velocity divided by time.
The original velocity is 15 kph, and the final velocity is 30 kph. Therefore, the change in velocity is 15 kph. 15/5=3 k/h/s
Answer:
C. Tip had the lower pressure, it was 652.71mmHg
Explanation:
To answer this question you need to convert both values into a common unit so you can compare directly.
87kPa = 652.71 mmHg
Answer:
increase in solvent temperature will increase the solubility of solid particle but decreases the solubility of gas particle.
Explanation:
In solid particle when temperature increases its help to break apart the solid particle and increase in kinetic energy of solvent results in increase in solubility of solid particles in solvent.
but in gas solute, increase in temperature of solvent causes the increase in motion of gas molecules means increase in kinetic energy of molecules in the gas which results in breakage of inter molecular bonds and removal of the molecules from the heated solution.
