All acids only conduct electric current when they are dissolved in water, because when they are in an aqueous medium, they undergo ionization, i.e. release <span>ions.</span><span>
HCl --> H</span>⁺ + Cl⁻
The bases also conduct electric current in solution, because the Ionic dissociation sufferers (release the existing ions in the formula) and molecular ionization, suffer the reacting with water and releasing ions.
NaOH ---> Na⁺ + OH⁻
hope this helps!
The speed of sound is given by the formula
Speed of sound = square root (Young's Modulus/density)
Young's modulus for gold = 78 GPa which is 7.8 * 10^10 Pa
Speed of sound = (7.8 * 10^10 / 19.3 ) = sqrt (4.04 * 10^9 )
Speed of sound = 6.36 * 10^4 m/s <<<=== answer.
Answer:
The total mass of reactants equals the total mass of products
Step-by-step explanation:
The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:
Reactants ⟶ products
Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
Answer:
Since the equation is balanced, So it have same number of oxygen in the reactants and well as product.
Oxygen in product = 8
Oxygen in reactant = 8
