A^2<span> + </span>b^2<span> = </span>c^2
that is answer
On the edges or the outer magnetic fields
D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.
CH3COONa+HBr ----> NaBr + CH3COOH
CH3COO⁻ +H⁺ ------> CH3COOH , because CH3COOH is a weak acid
Answer:

Explanation:
We can convert the formula units to moles and then use the molar mass to find the mass.
1. Moles of Pb(MnO₄)₂

2. Mass of Pb(MnO₄)₂
