A toilet might make a burping sound when flushing due to air that was trapped in the pipe. Sometimes giving the toilet a quick plunge will prevent this.
When a toilet bubbles when flushed, it is usually due to a blockage in the plumbing system. The blockage causes air to get trapped in the pipes, leading to the bubbling effect when the toilet is flushed.

Toilet bubbles appear when flushed because of air trapped in the pipes or a partial blockage in the drain. This can happen even if the toilet is not fully clogged.
The sewer
Your toilet may be leaking from the bottom when flushed due to a damaged wax ring seal or a cracked toilet base. This can cause water to seep out when the toilet is flushed. It is important to address this issue promptly to prevent further damage and water wastage.
Depends on if it needed to be flushed or not.
Bad venting
Water and waste
The toilet leaks at the base when flushed because the wax ring that seals the connection between the toilet and the floor may be damaged or worn out, allowing water to escape.
The toilet only leaks when flushed because there may be a problem with the flushing mechanism or the seal between the tank and the bowl. When the toilet is flushed, water is released from the tank into the bowl, and if there is a leak in the mechanism or seal, water can escape and cause a leak.
