Answer:
<u><em>Density is the same</em></u>
Explanation:
The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.
C describes plastics that can be recycled. Thermoplastic can be remolded and reheated after forming, whereas thermoset strengthens when heated
To determine the empirical formula and the molecular formula of the compound, we assume a basis of the compound of 100 g. We do as follows:
Mass Moles
K 52.10 52.10/39.10 = 1.33 1.33/1.32 ≈ 1
C 15.8 15.8/12 = 1.32 1.32/1.32 ≈ 1
O 32.1 32.1 / 16 = 2.01 2.01/1.32 ≈ 1.5
The empirical formula would most likely be KCO.
The molecular formula would be K2C2O3.
use the equation PV=nRT and solve the problem
Answer:
Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction:
Explanation:
Reaction quotient is the ratio of product of concentrations of products to product of concentrations of reactants at any time.
The same ratio at equilibrium (when rate of forward reaction becomes equal to rate of backward reaction) is equilibrium constant.
when Q < Kc, a forward reaction is favored.
When when Q > Kc, a backward or reverse reaction is favored
So the first statement that
a) A reaction quotient (Q) larger than the equilibrium constant (K) means that the reaction will favor the production of more products: false
b) No the rate of forward and backward reaction are equal.
c) c. Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction: True
d) Dynamic equilibrium indicates that the amount of reactants and products are equal: This could be static equilibrium but not dynamic.
