Answer:
Aqueous carbon dioxide, CO2 (aq), reacts with water forming carbonic acid, H2CO3 (aq). Carbonic acid may loose protons to form bicarbonate, HCO3- , and carbonate, CO32-. In this case the proton is liberated to the water, decreasing pH. The complex chemical equilibria are described using two acid equilibrium equations.

Answer:
A. Fetch.
Explanation:
The fetch-decode-execute process of simply the fetch-execute process of the CPU are stages the CPU follow to process information and the switch state or shutdown.
The stages of this process is implied in its name, that is, the stages are fetch, decide and execute.
The fetch stage retrieves the next instruction from the memory.
The decode stage converts the clear text instruction set to electronic signals and transfer it to the appropriate registers.
The execute stage is the action carried out in the arithmetic logic unit.
Answer:
C. 220.100.100.45 to 220.100.100.46
Explanation:
The Classless IP subnetting of 220.100.100.0 begins from the fourth octet of the IP address. To get 45 subnet mask, it uses 6 bits from the fourth octet, which approximately give 64 subnets, while the remaining 2 bits are used for host IP addressing.
The useable host IP addresses are gotten from the formula '
-2', with n=2 bits.
useable host IP addresses = 2^2 - 2 = 2 addresses per subnet.
While the 12th subnet is 12 x 2^2 = 44.
This means that the 12th subnet mask starts with 220.100.100.44 (as the network address) and ends with 220.100.100.47 as broadcast IP address, while '.45' and '.46' are the assignable addresses of the subnet.
