Answer:
He used Velocity and Radius.
Explanation:
The uncertainty truths contradicts Bohr's thoughts of electrons.
The rates of the forward and reverse reaction depends on the temperature on which the reaction will proceed, either endothermic of exothermic. it also depends of the concentration of the reactants and products. if the reaction is exothermic, so if the reaction temperature is increased then it will favor the forward reaction, then if the reaction is lowered then it will favor the reverse reaction
Answer:
1) THE AGE OF THE SAMPLE 2) URANIUM- LEAD DATING
Explanation:
Both carbon and lead belong to Group IV elements, and thus they have the same number of valence electrons.
<span>In each of the other options, the two elements belong to different groups, and thus they do NOT have the same number of valence electrons.</span>
