Hopefully this helps!!! :)))
Hello!
Fossil fuels are Carbon-based compounds that when heated in the presence of oxygen undergo a combustion reaction to produce thermal energy and gases. The chemical equation for the combustion of a generic Fossil Fuel (C) is the following:
C + O₂ →CO₂
From this chemical reaction, we can see that CO₂ (Carbon Dioxide) is produced, so the consumption of fossil fuels has increased the Carbon Dioxide concentrations in the atmosphere.
Have a nice day!
32g of oxygen is required to burn 4g of hydrogen.
Define molecular mass.
A specific molecule's mass is expressed in daltons and is known as the molecular mass (m) (Da or u). Due to the varying isotopes of an element that they contain, multiple molecules of the same substance can have distinct molecular weights.
The total atomic mass of every atom in a molecule, calculated using a scale with hydrogen, carbon, nitrogen, and oxygen having atomic masses of 1, 12, 14, and 16, respectively. For instance, water has a molecular mass of 18 (2 + 16), which consists of two hydrogen atoms and one oxygen atom. known also as molecular weight.
In ,2H2+O2-----> 2H2O
H 2 molecules have a mass of 2 g/mol.
The molecular weight of oxygen is 32 g/mol.
When the chemical equation is balanced,
To totally react, 32 g of oxygen are needed for every 22=4 g of hydrogen.

Answer and Explanation:
We need to remember the formulas:
- pOH = -log[OH-]
- pH = -log[H+]
- pH + pOH = 14
When given the concentration of OH-, denoted as [OH-], we can plug that value into the equation pOH = -log[OH-] to find the pOH. Once we have found the pOH, we can then subtract that value from 14 to determine the value of pH.
<h3>Pressure has additive properties meaning that if you add the partial pressures together, you obtain total pressure. P total = P1 + P2 + P3 + ... Pressure of container = pressure of H2 + Pressure of N2 + Pressure of F2 = 3atm + 2atm + 5atm = 10atm Hope that helped. ;)</h3>
