Most air pollution is a result of?
Carbon dioxide being given off when we burn fossil fuels.
Why don't matches catch fire as soon as they are in contact with the oxygen in the air?
To start any chemical reaction the reactants (ingredients) need to reach a certain energy level called the activation energy. Room temperature is not hot enough to provide the activation energy to ignite the materials in a match. Very few substances can ignite at room temperature.
Why is burning coal a combustion reaction?
this happens because when you burn fossil fuels such as coal, it emits things like c02 into the air and peaks the temperature.
What is one of the reactants when a candle burns?
Assuming it's a hydrocarbon, one of the reactants will be wax, in the form CxHx+2 Another reactant would be Oxygen, in the air. The products would be water, H2O and Carbon Dioxide, CO2.
What happens when gas is burned in an engine?
For a gas to burn in an engine, it must be mixed with air to provide oxygen. Liquid fuels are commonly made into a fine mist (or often a vapour) to promote good mixing of fuel and air. This fuel-air mixture will then burn, as a chemical reaction, and hopefully producing some spare energy from the reaction.
Which gas in the air is one of the reactants when substances burn?
Oxygen.
Does a fossil fuel burn in the air?
All fuels that 'burn' require air or an oxygen source for combustion. Therefore,fossil fuel also burn in the air.
What do you burn that is the major cause of air pollution?
Fossil Fuels
How do cars effect the air quality from the fossil fuels?
The pollution from the cars is hazardous to the air quality from fossil fuels. Fossil fuels have to burn a lot of gas and coal in order for cars to get driving.
How air polluted by hurning fuels?
The fuels get polluted because we throw our trash and garbage and burn them, because of this the air is also get polluted. We should take the right for saving our ENVIORMENT.
How the acid rain formed by burning fossil fuels?
The fossil fuels burn and come up to the air as pollution. It gets into a cloud, and when it rains, there is acid rain.
Most air pollution is a result of?
Carbon dioxide being given off when we burn fossil fuels.
What are an advantige and disadvantige of energy reasourse for fossil fuels?
A disadvantage of fossil fuels is that when you burn them to create energy, it pollutes the air. An advantage of fossil fuels is that we use them to power cars and many other things.
How does carbon and nitrogen affect the atmosphere?
Carbon affects the atmosphere when humans burn fossil fuels into the air and other chemicals
Is air a fuel?
Air is not a fuel. Most fuels such as gasoline or methane require air in order to burn, so air, or more precisely the oxygen in air, supports combustion, but it is not a fuel, it is an oxidising agent.
Why do candles burn in the air?
Burning is a reaction of oxidation, a reaction of oxygen with a substance. Candle components are flammable.
Why don't matches catch fire as soon as they are in contact with the oxygen in the air?
To start any chemical reaction the reactants (ingredients) need to reach a certain energy level called the activation energy. Room temperature is not hot enough to provide the activation energy to ignite the materials in a match. Very few substances can ignite at room temperature.
