1) 100s of millions of years ago Trees and plants fall into swamps
2) Layers of rotting plant matter builds up underwater
3) Over millions of years the weight of layers heat the plant matter and turn into Peat
4) Over millions of years more pressure and heat turns Peat into coal
<h3>
Answer:</h3>
54 g
<h3>
Explanation:</h3>
- The reaction between carbon and oxygen gas is given by the equation;
C(s) + O₂(g) → CO₂(g)
We are given;
18 g of Carbon
72 g of Carbon dioxide
- We need to calculate the amount of oxygen needed for the reaction.
- From the law of conservation of mass in chemical equation, the mass of the reactants is equal to the mass of the product.
Therefore;
Mass of Oxygen gas + mass of the carbon = Mass of carbon dioxide
Therefore;
Mass of Oxygen gas = mass of carbon dioxide - mass of carbon
= 72 g - 18 g
= 54 g
Therefore, the mass of Oxygen needed would be 54 g
Answer:
Nomenclatura de sodio
nomenclatura de compuestos iónicos En compuesto químico: Compuestos iónicos que contienen iones poliatómicos ... el compuesto NaOH se llama hidróxido de sodio, ya que contiene el catión Na+ (sodio) y el anión OH (hidróxido).
Explanation:
Solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. Solubility of a gas is inversely proportional to temperature.
So, the solubility of carbon dioxide gas in water is increased by increasing the partial pressure of carbon dioxide and by decreasing the temperature.
Answer:
Explanation:
The chemical combustion reactions use a compound called fuel (containing carbon and hydrogen atoms, example: CH4 methane) and oxygen, generating C02 (carbon dioxide) and H20 (water).
