Answer:
We write 50,000 in scientific notation,
it is written as 5 x 10⁴.
Hope it helps.
Wave velocity refers to speed, but can also be speed and direction.
1. Cu + 2AgNO3 ==> 2Ag + Cu(NO3)2 ... balanced equation. This is both a single replacement reaction and an oxidation reduction reaction.
Moles of Cu present = 19.0 g Cu x 1 mole Cu/63.55 g = 0.2990 moles Cu
Moles AgNO3 = 125 g AgNO3 x 1 mole AgNO3/169.9 g = 0.7357 moles AgNO3
Which reactant is limiting? It will be Cu because the mole ratio is 2 AgNO3 to 1 Cu and there is more than enough AgNO3. Thus, amount of Ag formed will depend on moles of Cu (0.2990)
Moles of Ag formed = 0.2990 moles Cu x 2 moles Ag/mole Cu = 0.598 moles Ag
Mass (grams) of Ag formed = 0.598 moles Ag x 107.9 g/mole = 64.52 g = 64.5 g of Ag (3 sig. figs.)
Answer:
33.3gtts/min
Explanation:
We can find the drops/minute with common proportions.
100cc/1hr * 200gtts/1cc * 1hr/60min ≈ 33.3gtts/min
Best of Luck!
Explanation:
Cause the clumps are so compacted together that it is harder to brake apart but the one that are separated are easy cause they do not have all the pressure on them and when they go to add reaction it is faster
