Answer:
In a chemical reaction, chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal. The result of this equilibrium is that the concentrations of the reactants and the products do not change.
Explanation:
Answer:
Carbon dioxide gas
Explanation:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere.
1×10^-4 = 0,0001M
pH = -log[H+]
pH = -log0,0001
pH = 4
Thus, the fourth level can hold up to 32 electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. The sublevels of the first four principal energy levels and the maximum number of electrons that the sublevels can contain are summarized in Table 5.1<span>.</span>
Answer: Nitrogen has maximum covalency 4, because we know that maximum electrons a shell can accommodate is 2n2, and hence it can have only 8 electrons. So covalency cannot exceed more than 4.
