Solid Silicon can be reacted with Nitrogen gas at a high temperature to form silicon nitride (Si3N4).
1.20 moles of Silicon are added to 1.00 moles of Nitrogen gas.
(5 Points) Balance the equation and indicate the phases.
Si (___) + N2 (___) → Si3N4 (___)
(5 Points) What is the limiting reactant? You must show your work.
Composed of molecules formed by atoms of two or more different elements.
Answer:
True
Explanation:
It is true that every element in the periodic table follows the Aufbau's principle.
The principle states that "the sublevels with lower energies are filled up before those with higher energies".
- Sublevels do not fill up in numerical order.
- This is true when writing the electronic configuration of all atoms on the periodic table.
54 protons.
An ion with a charge of 3+ means it has lost electrons to become a cation. Since the number of protons and the number of electrons are the same in an atom, add 3 to 51 to find the number of protons.
No. of protons = 51 + 3 = 54
Answer:
think what you mean is that metal FEELS colder than wood if they're both at room temperature. That's because metal conducts heat much better than wood does. Since your hand is hotter than room temperature, both the metal and the wood conduct heat away from it.
