Nearly all life on Earth gets its energy from the sun, and the sun gets its energy through the process of nuclear fusion, which is why these type of energy is important to life on Earth.
<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds
will contain both metals and non-metals, or at least one polyatomic
ion. *Acids will always include the (aq) symbol beside the formula, and
the name will include the word acid.</span>
Answer:
The final volume when pressure is changed is 126.1mL
Explanation:
Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:
P₁V₁ = P₂V₂
<em>Where P is pressure and V volume of 1, intial state and 2, final state.</em>
<em />
Computing the values of the problem:
350mmHg*200mL = 555mmHgV₂
126.1mmHg = V₂
<h3>The final volume when pressure is changed is 126.1mL</h3>
Answer:
3
Explanation:
There are three different elements in given chemical equation. These elements are hydrogen, oxygen and carbon.
Chemical equation:
2CH₄ + 4O₂ → 2CO₂ + 4H₂O
This equation shows the burning of methane. When methane burns in the presence of oxygen it produced water and carbondioxide.
We can see that all the reactant and product are made up of only three elements carbon, hydrogen and oxygen.
There are two reactant and two products in given reaction.
This reaction also follow the law of conservation of mass.
We can see that there are two carbon eight hydrogen and eight oxygen atoms on both side of equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
