Answer:
16.4moles
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms.
This clearly indicates that 1mole of (NH4)3PO4 also contains 6.02x10^23 atoms.
Now, if 1mole of (NH4)3PO4 contains 6.02x10^23 atoms,
Then Xmol of (NH4)3PO4 will contain 9.87X10^24 atoms i.e
Xmol of (NH4)3PO4 = 9.87X10^24/6.02x10^23 = 16.4moles
Hello, Brainly User!
A heterogeneous equilibrium reaction is when there are different phases in the reaction. An equilibrium reaction is a reaction that can go in both the forward and reverse directions, and the concentrations of the reactants and products remain the same.
So therefore, your answer is A. Heterogeneous!
Hope i helped and i was honored to answer your question!
Have a great day..

Answer:
The correct option is:
A) by direct or indirect contact between objects at different temperatures
Explanation:
Heat can be transferred in three different methods:
Conduction, Convection and Radiation
Conduction is heat transfer through direct contact between substances at different temperatures.
Convection is the heat transfer which takes place through air currents.
Radiation is the heat transfer that does not require contact between two objects.
Hence, heat transfer can take place through direct or indirect contact between objects at different temperatures.
<span>It is said
that the carbon atom is a tetra valence which means, it contains 4
covalent bonds that can be bonded with other atoms. Therefore, it needs 4
hydrogen atoms to bind into 1 carbon atom. Carbon Atom contains a total of
6 electrons that occupies the 2 shells which is the K (have 2 electrons)
and L (have 4 electrons) shells. The
outermost shell of carbon atoms that contains 4 electrons is called as
valence shell. In order to complete its octet, carbon Atom needs other
atoms to share their valence electrons.</span>
