The most efficient burning occurs at a stoichometric ratio of fuel to oxidizer. Since this happens at different ratios for different fuels, a mixture optimized for one fuel is of necessity sub-optimal for a different fuel.
Because different fuels need different amounts of Oxygen and heat to ignite.
2C3H8 +7 O2 >>6 CO +8 H2O 2C4H10 + 9O2 >> 8CO +10 H2O These are the balanced equation for propance and butane!
Different stains are difficult to remove for different reasons. Oil stains are difficult because they resist the water used to clean them. Protein stains are difficult because they can change and become more stuck into the fabric over time adn with heat. Dye stains are difficult because they are products designed to change the color of things, and clothes are not an exception.
The air on Earth is a mixture of several different gases, however it is primarily Nitrogen (Approx. 78%). Thus, it is difficult to test for the presence of Nitrogen as the result of an experiment because it is already present in abundant supply in the air around you.

For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
No. The larger the cell becomes the more difficult the nutrients can travel around.
Some major problems of coordination include making sure everyone is working together and ensuring everyone has the same goal. Because everyone is different, it is often quite difficult to properly and efficiently coordinate efforts.
Produces power efficiently. Very expensive and difficult to decommision at end of life.
Facies (the characteristics of a rock unit which differentiate it from others around it) identification helps geophysicists infer the presence of hydrocarbon-bearing rock. This is particularly useful in cases where there is no well log data or exploratory holes is expensive and/or difficult, such as in deep-water systems.
Pedestal sinks are difficult to install. You may want to talk to your contractor if you're not good at installing appliances.
Yes, I have one in my kitchen. But remember that you will find it difficult to get appliances that will fit underneath.
No, you will have different temperatures of water inside the water heater, which will make it difficult to get a consistent temperature out of a shower valve or faucet. The heater will also not work correctly or efficiently.
A machine exerts a great amount of energy. This is because machines are meant to do things that are often difficult or time consuming quickly and efficiently.
Complicated.
Major appliances are sold at major retail stores or appliances stores. Major appliances are appliances that complete housekeeping tasks, such as washers and dryers, stoves, refrigerators, and dishwashers. The appliances differ from small appliances because they are generally difficult to move and remain fixed in place. When a home owner decides to purchase major appliances, they should shop around for the best deal possible. Many stores that sell major appliances will have special sales and deals for the customers. Certain items can even be found at clearance price which allows the shopper to save a lot of money. Major appliances usually include a manufacturer's warranty with the purchase. A manufacturer's warranty is valid for 30 days to a year, depending on the type of appliance and the company. The business that the major appliances are purchased from can also offer an extended warranty. The price of the extended warranty is determined by the number of years and the price of the major appliances. A major appliances store is the best place to purchase new or used appliances. The employees are trained about the appliances and are able to answer any questions that the customer may have. If the employee does not know the answer, they will help the customer find the answer. Customer service and arming the customers with knowledge about their new appliances is an important factor to major appliances store employees. Repair services are generally offered to customers with the purchase of a major appliance. Companies that do not have repair services are able to give the customer a referral to a company who can complete the repair. Some companies will offer in-home repair if the repair job allow it. If the repair needs to take place at the company or manufacturer, the company will take care of it for owner of the major appliance. If the appliances are not covered by warranty, the fee for the services will depend on the repair that is needed.
