K+(aq) and Br-(aq)
Because the reactant also appears on the product side in the same form, it does not go through any chemical reaction and is therefore a spectator ion.
Answer:
0.51 moles of gas
Explanation:
Given data:
Pressure of gas = 50.65 kpa (50.65 /101 = 0.5 atm)
Volume of gas = 25 L
Temperature of gas = 300 K
Number of moles of gas = ?
Solution:
The given problem will be solve through ideal gas equation,
PV = nRT
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
Now we will put the values.
0.5 atm × 25 L = n × 0.0821 atm.L /mol.K × 300 K
12.5 atm. L = n × 24.63 atm.L /mol
n = 12.5 atm. L /24.63 atm.L /mol
n = 0.51 mol
Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges. While the process is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
The first one water + carbon dioxide + sunlight --> oxygen + glucose
Potassium Iodide have a lot of strong bonds which requires a very high temperature (high energy) to break them and change into a different state of matter.
