Which fuels release chemical energy?
Fuels such as gasoline, diesel, natural gas, and coal release chemical energy when they undergo combustion reactions. This chemical energy is then converted into heat or mechanical energy to perform work.
Would burning diesel fuel be a chemical change?
Yes, burning diesel fuel is a chemical change because it involves a chemical reaction where the fuel reacts with oxygen in the air to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. The original diesel fuel is transformed into different substances during combustion.
Is burning diesel a chemical change?
Yes, burning diesel is a chemical change. During combustion, the diesel fuel reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This reaction involves a rearrangement of atoms and the formation of new substances.
What is the difference between Diesel and High Speed Diesel?
The difference between diesel and high speed diesel is that high speed diesel has special cleaning detergents added to it. These detergents clean the injectors, which makes the vehicle run better.
Is diesel nonpolar?
Diesel is a mixture of hydrocarbons, which are typically nonpolar molecules. This means that diesel is generally nonpolar.
Is burning petrol in a car engine exothermic or endothermic?
Burning petrol in a car engine is an exothermic process because it releases heat energy. The combustion of petrol with oxygen produces carbon dioxide, water vapor, and heat as byproducts, which powers the engine.
Which fuels release chemical energy?
Fuels such as gasoline, diesel, natural gas, and coal release chemical energy when they undergo combustion reactions. This chemical energy is then converted into heat or mechanical energy to perform work.
What happens when you ignite potassium nitrate and diesel?
When you ignite a mixture of potassium nitrate and diesel fuel, the potassium nitrate acts as an oxidizer, providing oxygen for the combustion of diesel fuel. The diesel fuel burns in the presence of the oxygen from potassium nitrate, resulting in a highly exothermic reaction that produces heat, light, and gases like nitrogen, carbon dioxide, and water vapor. This reaction can be used in pyrotechnics to create controlled explosions or propulsion in rocket engines.
Is diesel an oxidizer?
No, diesel is not an oxidizer; it is a type of fuel primarily composed of hydrocarbons. In combustion, diesel acts as a fuel that is ignited in the presence of an oxidizer, typically oxygen from the air. The combustion process involves the reaction between the diesel fuel and the oxygen, which produces energy, carbon dioxide, and water. Oxidizers are substances that can accept electrons in a chemical reaction, while diesel serves as a source of energy rather than facilitating oxidation.

How do you make black diesel?
Black diesel, often referred to as biodiesel or waste vegetable oil diesel, is made by converting used cooking oil or animal fats into a usable fuel. The process involves filtering the oil to remove food particles, then mixing it with methanol and a catalyst (usually sodium hydroxide or potassium hydroxide) to facilitate a chemical reaction called transesterification. This reaction separates the glycerin from the fatty acids, resulting in biodiesel and glycerin byproducts. The biodiesel can then be used directly in diesel engines or blended with regular diesel fuel.
Can a hospital experience a power outage?
Many hospitals have back-up diesel generators. Smaller, rural hospitals may not, and could undergo a power outage.
Would burning diesel fuel be a chemical change?
Yes, burning diesel fuel is a chemical change because it involves a chemical reaction where the fuel reacts with oxygen in the air to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. The original diesel fuel is transformed into different substances during combustion.
Is burning diesel a chemical change?
Yes, burning diesel is a chemical change. During combustion, the diesel fuel reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This reaction involves a rearrangement of atoms and the formation of new substances.
Can diesel fuel go bad after sitting for 3 years?
Yes, diesel fuel can go bad after sitting for three years. Over time, it can undergo oxidation and microbial growth, leading to the formation of sludge and sediment. Additionally, the fuel's additives may degrade, reducing its effectiveness. It's advisable to test or treat old diesel before use to ensure optimal performance.
Does diesel fuel melt styrofoam?
Yes, diesel fuel can dissolve or break down Styrofoam (expanded polystyrene) due to the solvent properties of hydrocarbons in diesel. When Styrofoam comes into contact with diesel, it can lose its structural integrity, causing it to soften and melt. However, the extent of the reaction may vary depending on the concentration of diesel and the duration of contact. It's important to handle such materials carefully, as the combination can pose environmental and health risks.
What substances are considered fuels?
Substances that can undergo combustion to produce heat or energy are considered fuels. Common examples include gasoline, diesel, natural gas, coal, and wood.
