Ethanol is highly flammable. It is a volatile substance that can easily catch fire when exposed to an ignition source such as a spark or flame. Due to its flammability, it is important to handle ethanol with caution and store it in a safe manner away from sources of heat or flames. **

Paper is generally considered to be flammable, as it is made from cellulose fibers which can easily catch fire and burn. The flammability of paper can vary depending on factors such as the type of paper, its thickness, and any additional coatings or treatments it may have. While paper itself can easily ignite and burn, it is important to note that modern fire safety standards often require paper products to be treated with flame retardant chemicals to reduce their flammability. **

Hydrocarbons are generally flammable because they consist of carbon and hydrogen atoms, which can easily react with oxygen in the air to produce heat and light. The flammability of hydrocarbons varies depending on their chemical structure and the presence of other elements or functional groups. For example, simple hydrocarbons like methane and propane are highly flammable, while more complex hydrocarbons like long-chain alkanes or aromatic compounds may have different flammability properties. Overall, hydrocarbons are known for their flammability and are commonly used as fuels. **

Diesel is considered to be less flammable than gasoline. It has a higher flash point, which means it requires a higher temperature to ignite compared to gasoline. However, diesel can still ignite under the right conditions, so it should be handled and stored with care to prevent the risk of fire. Overall, diesel is less flammable than gasoline, but it still poses a fire hazard if not handled properly. **

Alkanes are generally considered to be non-flammable or have low flammability. This is because alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms and are therefore relatively stable. However, as the chain length of alkanes increases, their flammability may also increase. Additionally, alkanes can become flammable when mixed with air in certain concentrations, leading to combustion. Overall, while alkanes are not highly flammable on their own, they can still pose a fire hazard under certain conditions. **

The flammability of gases refers to their ability to ignite and burn in the presence of oxygen. Some gases, such as methane and hydrogen, are highly flammable and can ignite easily with a spark or flame. Other gases, like carbon dioxide and nitrogen, are non-flammable and do not support combustion. It is important to understand the flammability of gases in order to handle and store them safely. **

The savings bank may be blocking online banking customers for security reasons. They may have detected suspicious activity on certain accounts and are taking precautionary measures to protect their customers' funds and personal information. Additionally, the bank may be conducting routine maintenance or updates to their online banking system, temporarily restricting access to ensure a smooth and secure user experience once the maintenance is complete. It is also possible that there may be technical issues or glitches with the online banking platform that need to be resolved before customers can access their accounts again. **

Savings bank transactions can typically be deleted by accessing the account statement or transaction history on the bank's online portal or mobile app. From there, you can select the specific transaction you wish to delete and look for an option to remove or delete it. If you are unable to delete the transaction yourself, you can contact your bank's customer service for assistance in removing the transaction from your account history. It's important to note that some transactions may not be able to be deleted, especially if they are already processed or finalized. **
