Answer:
Option A. 1.8×10²⁴ molecules.
Explanation:
Data obtained from the question include:
Number of mole of methane = 3 moles
Number of molecules of methane =?
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules.
Thus, 1 mole of methane equally contains 6.02×10²³ molecules.
With the above information in mind, we can obtain the number of molecules in 3 moles of methane as follow:
1 mole of methane contains 6.02×10²³ molecules.
Therefore, 3 moles of methane will contain = 3 × 6.02×10²³ = 1.8×10²⁴ molecules.
Thus, 3 moles of methane contains 1.8×10²⁴ molecules.
Answer:
Compounds are pure substance consisting of two or more different atoms
Professor of Physics Carlo Rubbia
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.
Explanation:
Answer:
The answer to your question is letter d. Sr(ClO₃)₂
Explanation:
Data
Reactants HClO₃ and Sr(OH)₂
This is a neutralization reaction because the reactants are a base (Sr(OH)₂) and an acid (HClO₃).
The products in a neutralization reaction are always water and a salt.
Balanced chemical reaction
Sr(OH)₂ + HClO₃ ⇒ H₂O + Sr(ClO₃)₂
