Answer:
the correct answer is E
Explanation:
None of the options is correct, because entropy is the thermodynamic magnitude that indicates the degree of molecular disorder of a system, in exothermic processes energy or heat is released to the medium and energy is taken from the medium in endothermic processes, entropy if it depends of the temperature since the temperature is what sometimes determines if the process is spontaneous or not, and the delta universe in spontaneous processes is not always greater than zero, it is more frequently less than zero with negative values.
Answer:
Species present in the solution after complete reaction: 
Explanation:
First balance the chemical equation,
calculation of mili moles of each:
mili mole of AgNO3= 15mili mole;
mili mole of K2CrO4=10 mili mole;
From balance equation,
2 mili mole of AgNO3 reacts with 1 mili mole of K2CrO4
hence 1 mili mole of AgNO3 reacts with 0.5 mili mole of K2CrO4
15 mili mole of AgNO3 reacts with 7.5 mili mole of K2CrO4
so only 7.5 milimole will be used in the reaction and 2.5 mili mole left in solution.
species present in the solution after complete reaction:
are soluble in water so it will dissociate in the solution
Answer:
mass and height of the object.
Answer:
Explanation: Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. Hope that helps!
