Two or more substances in variable proportions, where the composition is variable throughout are a a homogeneous mixture. b a so
REY [17]

<u>Answer:</u> In heterogeneous mixture, the composition remains variable throughout.

<u>Explanation:</u>

For the given options:

Homogeneous mixtures are defined as the mixtures that appears uniformly throughout the solution and the particle size or shapes are not different. The composition remains constant throughout.

A solution is defined as the solution in which the components gets completely dissolved in it. Particles are evenly spread in these solutions. These solution does not scatter light falling on it. The composition remains constant throughout.

An amorphous solid is defined as the solid in which the constituent particles of the matter are arranged in the random manner. The composition remains constant throughout.

A heterogeneous mixture is defined as the mixture in which component are unevenly spread throughout the solution. The size and shape of the particles differ in these mixtures. These mixture scatter the light falling on it.  The composition do not remains constant throughout.

Compound is defined as the chemical specie which is formed by the combination of two or more different type of atoms. <u>For Example:</u> H_2O,O_2 etc...The composition remains constant throughout.

Hence, in heterogeneous mixture, the composition remains variable throughout.

Is the energy change accompanying the synthesis of a compound from its elements in their standard state?
worty [1.4K]

The synthesis of a compound from its elements in their standard state, accompanied by a change in energy that is known as standard enthalpy of formation of a compound. The standard state of a substance is the most stable physical state of the compound that exist at STP that is at 1 atm, 273 K temperature. So the answer is yes, the energy change accompanying the synthesis of a compound from its elements in their standard state.
