Final answer:
Scientists use a range of skills, primarily the scientific method, and tools, such as various lab equipment and technology, to conduct their research.
Explanation:
Scientists use a variety of skills and tools to conduct their research and investigations. The primary skill they possess is the scientific method, a systematic way of understanding the world around us, which involves observation, question formulation, hypothesis testing, data collection, data analysis and conclusion drawing.
As for tools, scientists use a range of laboratory equipment like microscopes and pipettes for biological research, telescopes for astronomical studies, spectrophotometers for chemical analysis, computers for data analysis, and more. Technology is greatly used in science as it aids in thorough and precise investigations.

Answer and Explanation:
It is worthy to be mentioned that the equilibrium in this reaction is dynamic equilibrium.
- In terms of concentration: the concentration of reactants (CH4) and products (C2H2 & H2) do not change and be constant at the equilibrium, that 2 moles of CH4 give one mole of C2H2 and 3 moles of H2.
- In terms of reactions that occur: the reactions that occur at the equilibrium are the forward and the reverse reaction. The forward reaction: 2CH4 → C2H2 + 3H2 and the reverse reaction: C2H2 + 3H2 → 2CH4.
- In terms of reaction rates: At equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.
Answer:
In a chemical reaction equilibrium is in the state which reacts with both products and reactants. Both reverse and forward are happening and both reaction rates forward and reverse are equal.

Answer:
No, because it is an intensive quantity.
Explanation:
According to IUPAC, an intensive quantity is one whose magnitude is independent of the size of the system/sample, on the other hand an extensive quantity is one whose magnitude is additive for subsystems.
Exemples of intensive quantities: temperature, density, concentration.
Exemples of extensive quantities: mass, volume, energy.

Equation
CaCO3 ===> CaO + O2
Solution
If you start with this equation, then the balance numbers (molar ratios) are
- 1 for the CaCO3
- 1 for the CaO
- 1 for the O2
If you want 2.35 moles of CaO then you are going to have to start out with 2.35 moles of CaCO3
Final answer:
In the decomposition of calcium carbonate to form calcium oxide, there is a 1:1 mole ratio. Therefore, to get 2.35 moles of calcium oxide, 2.35 moles of calcium carbonate are required.
Explanation:
To answer this question, you need to consider stoichiometry, which is the study of the relationships or ratios between the amounts of products and reactants in chemical reactions. The balanced chemical equation for the thermal decomposition of calcium carbonate (CaCO3) to form calcium oxide (CaO) and carbon dioxide (CO2) is:
CaCO3(s) → CaO(s) + CO2(g)
This equation tells us that 1 mole of CaCO3 will produce 1 mole of CaO. Therefore, if we need 2.35 moles of CaO, we would need 2.35 moles of CaCO3 because of the 1:1 mole ratio in the chemical reaction.
