Answer: = C
Explanation:
evaporating some of the water contained in the solution will increase the concentration of the resulting solution, because there will be concomitant increase in the number of moles of the solute left in the solution.
Answer:
products are copper and aluminium chloride
reactants are aluminium and copper chloride
Explanation:
products are formed at the end of a reaction
reactants are what's reacting to form the products ie the things at the start of the equation
Answer:
0.64 mol
Explanation:
Using ideal gas equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = 0.72atm
V = 22 L
T = 30°C = 30 + 273 = 303K
n = ?
Using PV = nRT
n = PV/RT
n = (0.72 × 22) ÷ (0.0821 × 303)
n = 15.84 ÷ 24.88
n = 0.64 mol
Answer: C. all particles of matter move very quickly
Explanation:
Heat is how fast the molecules are moving in something. This means even a solid's molecules are moving.
