can be used to clean the acid.
Further Explanation:
In order to clean the car battery corroded by acid, the following steps are followed:
Step 1: Battery needs to be touched by hands so it is to make sure that the car is turned off.
Step 2: The terminals of the battery are removed. This is done by first removing the negative terminals, followed by the removal of the positive terminal.
Step 3: Battery needs to be checked properly for any cracks in it. If it is found to be having any cracks, it needs to be replaced.
Step 4: A white substance appears on the corroded battery that needs to be cleaned. Since the acid is the corroding substance, baking soda or sodium hydrogen carbonate is used for the cleaning purpose. A paste of baking soda and water is formed and it forms bubbles of carbon dioxide, thereby washing away the corrosion.
Step 5: Everything needs to be dried with the help of cloth or towel.
Step 6: Petroleum jelly is added to the terminals of the battery in order to prevent future corrosion.
Step 7: The terminals of the battery are reconnected by first connecting the positive terminal and then negative terminal.
Therefore baking soda or sodium hydrogen carbonate can be used to clean the acid on car batteries.

Answer: The resultant pressure is 3.22 atm
Explanation:
Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
(At constant volume and number of moles)
where,
= initial pressure of gas = 2.79 atm
= final pressure of gas = ?
= initial temperature of gas = 273K
= final temperature of gas = 315 K
Thus the resultant pressure is 3.22 atm
