Answer:
Ba(OH)2(aq) + CO2(g) = BaCO3(s) + H2O(l)
Reaction type: double replacement
Explanation:
Answer
a) : = +ve
b) : = -ve
c) : = +ve
d) : = +ve
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
a)
As solid is moving to ions form , randomness increases and thus sign of is positive.
b)
As gaseous reactants are converted to solid products , randomness decreases and thus sign of is negative.
c)
As liquid is changing to gas randomness increases and thus sign of is positive.
d)
As 8 moles of gaseous reactants are converted to 11 moles of gaseous products , randomness increases and thus sign of is positive.
All monomers have the capacity to form chemical bonds to at least two other monomer molecules. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers.
They do not change the nature of the substance unless a chemical change occurs along with the physical change. These may be irreversible, but the result is still composed of the same molecules. When you cut your hair, that is a physical change, even though you can't put the hair back on your head again
The force equal but opposite to the one shown is : ( D ) The force that the branch applies to the kitten
<h3>Opposite and equal forces </h3>
The force of gravity/weight of an object is equal and opposite to the reactive force because it cancels the effect of the weight of the object on the surface. In option D the force that the branch applies to the kitten resting on it is equal and opposite to the weight of the kitten.
Hence we can conclude that The force equal but opposite to the one shown is The force that the branch applies to the kitten.
