Calcination use temperatures roughly twice that of typical roasting. The main idea is to use high temperatures and decompose the material being heated fairly faster. Roasting tries to changes the food products by starting and supporting a number of chemical reactions within the food that results in pleasant flavor, greater availability of certain ingredients.
Answer:
[AB] is 0.65 M
Explanation:
Let the concentration of AB after 10.3s be y
Rate = ky^2 = change in concentration of AB/time
k = 0.2 L/mol.s.
Change in concentration of AB = 1.5 - y
Time = 10.3s
0.2y^2 = 1.5-y/10.3
0.2y^2 × 10.3 = 1.5 - y
2.06y^2 = 1.5 - y
2.06y^2 + y - 1.5 = 0
The value of y must be positive and is obtained using the quadratic formula
y = [-1 + sqrt(1^2 -4×2.06×-1.5)]/2(2.06) = [-1 + sqrt(13.36)]/4.12 = 2.66/4.12 = 0.65 M
Answer:
Cupric oxide, or copper (II) oxide,
Explanation:
Correct me if im wrong tnx:<
The answer is false. The particles in a suspension are not dissolved into the solvent rather they are suspended or dispersed into the solvent, Suspension is a heterogeneous mixture where solute-like particles settle out of a solvent-like phase. Examples are mercury in shake in oil, oil shake in water, and chalk in water.
<span>You can't substitute that. Substitution is a reaction between acid and metal. Acid+metal ---> salt+H2
example : H2SO4+Al ---> Al2(SO4)3+H2 so,substitution of hno3 solution for 3M h2so4 is not possible</span>
