Since molarity is defined as moles per liter, the product of the molarity and volume will remain constant as mole solvent is added. So let's set up an equality to express this
m0*v0 = m1*v1
where
m0, v0 = molarity and volume of original solution
m1, m1 = molarity and volume of final solution.
Solve for v0, then substitute the known values and calculate:
m0*v0 = m1*v1
v0 = (1.75 M * 500 ml)/8.61 M
v0 = (1.75 M * 500 ml)/8.61 M
V0 = 101.6260163
Rounding to 3 significant figures gives 102 ml.
So the original volume of the 8.61 M H2SO4 solution was 102 ml or 1.02x10^2 ml.</span>
Answer: Option (c) is the kinetic energy.
Explanation:
The kinetic energy present within the particles of a substance is known as thermal energy. Measure of average kinetic energy of particles of a substance is known as temperature.
Whereas heat defined as the transfer of thermal energy from a hot object to a cold object.
Enthalpy is defined as the heat gained or lost by a substance in a chemical reaction.
Thermodynamics is the study of relation between heat and work with chemical or physical changes.
Thus, we can conclude that a measure of kinetic energy of particle motion within a substance is temperature.

Explanation:
The answer above is correct (I took a test on this)
Answer:
Stone does not have organic matter in it to burn in presence of air. Hence, it is a non combustible.
Rocks are quite bundled up together. Hence, they are very difficult to get mixed together.
