Almost always, the first way in which biology researchers present the results of their latest research is to discuss the results of previous research that they want to build off of.
The Weight is 140 and the mass is 15 can you give me brainlylist pls
I hope this helps I mean it’s easy
Answer:
B
Explanation:
A is wrong because heat is what makes the process faster.
B is right because the finer grains are able to dissolve at a higher rate since the amount of one grain reduces it's time to dissolve.
C is wrong because simply adding more water will not increase or decrease the dissolving rate.
Answer:
Average atomic mass = 63.3896
Explanation:
Step 1: Find how much Cu-65 we have
1 - Amount of Cu-63 = Amount of Cu-65
1 - 0.6915 = Amount of Cu-65
Amount of Cu-65 = 0.305
Step 2: Find the average atomic mass of Cu
(0.6915 x 63) + (0.305 x 65) = <em>Average atomic mass</em>
(43.5645) + (19.825) = <em>Average atomic mass</em>
63.3895 = <em>Average atomic mass</em>
Therefore the average atomic mass of Cu is 63.3895 atomic mass units
