The air will be belched out at some point, but the main concern is that air is not getting to the lungs. Tilt the head back and try again.
During rescue breathing some of the air given by the resuscitator may go down the throat to the patients stomach which causes gastric distention.
During CPR, the chest compressions are applied; during rescue breathing there are no chest compressions used.
When a person has stopped breathing and can not breathe on his own, rescue breathing (or Mouth-To-Mouth Resuscitation) is given to try and saved the persons live (in addition to CPR and/or defibrilation).
Giving very large breaths during rescue breathing can force air to reach the stomach, causing the patient to vomit. Vomiting while the patient is unconscious poses a risk to airway management as it may become obstructed. Furthermore, you do not have time to be giving very slow, forceful breaths are chest compressions take precedence in cardiopulmonary resuscitation.
after 5 repetitions of alternatively rescue breathing and compressions.
A breathing barrier device should be used if providing rescue breathing to minimize the risk of disease transmission.
Twenty one percent, which is the equivalent of room air.
For an Adult, if there are no signs of life, immediately go to CPR. For an Infant or Child, if there is no breathing, but a pulse start rescue breathing; 1 breath every 3 seconds.

That question is not fully correct. When doing mouth to mouth rescue breaths, it is important to inflate the chest completely by blowing a strong breath into the patients mouth. In an infant or child, you are advised not to take a full breath in because any excess air goes to the stomach and is regurgitated in the form of vomit. If you are sufficiently trained to use a device that replaces rescue breathing (known as a bag-mask) be careful not to squeeze the bag fully as any excess air will travel down to the stomach and the patients stomach contents will be expelled through the mouth. This is not only unpleasant, it poses an airway obstruction threat. In summary, inflate the patient's chest fully and wait for it to rise down between each breath. You should only allocated a maximum of three seconds for theo two breaths before going back to chest compressions. Compressions are more important than rescue breathing.
Agonal breathing will not support life; rescue breathing (or CPR if no pulse) is required.
If your are not trained in CPR or rescue breathing then you should not be giving rescue breaths as you can injure the victim. The lay rescuer should only provide compressions at a rate of 100 compressions per minute. AHA provides courses to learn CPR/ rescue breathing which are very beneficial.
