In setting up and balancing equations, it is important to know the chemical formula of the substances involved and also it is important that the number of elements in both sides should be equal. We do as follows:

2CH4 + 2NH3 + 3O2 = 2HCN + 6H2O

Hope this helps.

An infant ibuprofen suspension contains 100 mg/5.0mL suspension. The recommended dose is 10 mg/kg body weight.How many millilite
Molodets [167]
Converts the 25 lb to kg 

multiply the kilograms by the dose (10 mg/kg)

multiply the amount of ibuprofen by the conversion factor of the concentration of the suspension to calculate the mL

25 lb x  0.453592 kg/1lb=  "A kg"

A kg x 10 mg/kg = B mg

B mg x  5.0 mL/ 100 mg = "C mL of suspension"

Given that hclo4 is a strong acid, how would you classify the basicity of clo−4?
Mandarinka [93]
As a conjugate base of a strong acid,ClO4-would be classified as having a negligible basicity. The basicity of a chemical species is normally expressed by the acidity of the conjugate acid. The basicity of an acid is the number of hydrogen ions, which can be produced by one molecule of the acid.

How does classifying the components of air help us to solve the air quality crisis

Air pollution is

1. Coal

Burning all fossil fuels is bad, but coal is the worst. When burnt, it releases more carbon dioxide (CO2) per unit of energy than oil or gas – which means it heats up our planet faster.

Coal is toxic too. Burning it releases elements like mercury and arsenic, and small particles of soot which contribute to air pollution. When we breathe it in, that soot harms our heart and lungs and even increases our risk of strokes.

But the worst thing about coal is how widespread it is. Coal provides more than a third of the world’s electricity. That’s more than any other single source! These power plants affect air quality for hundreds of kilometres – and are often placed right in the heart of cities – so countless millions of people get little respite from the pollution these plants cause.

We desperately need to wean ourselves off coal, and get our power from clean sources like wind, sun and tides.

Some counties have started. In 2019, coal power had its biggest slump ever recorded! But we need every country in the world to move much faster towards renewable energy. Greenpeace International has even mapped out how they could go about

Air pollution is indeed a crisis, but it’s a crisis we can solve – and around the world, people are solving it! Here’s what that looks like.

2. Cars

Most cars run on oil – petrol and diesel. And just like burning coal, burning oil comes with a huge environmental price tag. Petrol and diesel cars emit CO2 and other gases which heat our planet. On top of other nasties, the exhaust fumes these cars produce contain Nitrogen Dioxide (NO2), which is another pollutant that harms our health.

Cities around the world are waking up to the joys of car-free travel. From pedestrian zones, to proper public infrastructure to comprehensive and affordable public transport, there are so many ways cities can help us go car-free more often. And the benefits are many – from more space and cleaner air to a more active and healthy population.

But for those journeys that still need cars, we should start thinking about cars very differently. Rather than petrol and diesel, we should power cars with electricity.

3. Air pollution is no match for all of us, working together. All the solutions listed here are already happening around the world because people came together and demanded it.

Concerns about air pollution made Shenzhen, China electrify their bus fleet. Parents in Belgium mobilised because the air in schools was so dirty. Now, Brussels, its capital city, is banning petrol and diesel cars from 2030 and investing in public transport and cycling infrastructure. And around the world, concerns about the climate impacts of coal are causing governments to look into new ways of getting their power- Turkey has closed five coal power plants in 2020 alone!
