Mixtures – two or more substances that are not chemically combined<span> with each other and can be </span>separated<span> by physical means. The substances in a mixture retain their individual properties. Solutions – a special kind of mixture where one substance dissolves in another.</span>
Platinum, symbol Pt is an element
The atomic number of an element gives the element it's identity. This is also known as the number of protons within an element. If you have the number of protons but don't know the element's atomic mass, add the protons and neutrons to get the mass number.
I hope this helped!
Answer:
A precipitation reaction is one in which substances in solution are mixed and an insoluble product is made. The insoluble product is called a precipitate and can be seen as a solid forming in the reaction mixture.
Answer : The value of 
of this reaction is, 
At equilibrium, [L-malate] > [oxaloacetate]
Explanation :
The relation between the equilibrium constant and standard Gibbs free energy is:
where,
= standard Gibbs free energy = +30 kJ/mol = +30000 J/mol
R = gas constant = 8.314 J/K.mol
T = temperature = 
= equilibrium constant = ?
The given reaction is:
Therefore, the value of of this reaction is,
As, the value of < 1 that means the reaction mixture contains reactants.
At equilibrium, [L-malate] > [oxaloacetate]
