Answer: The theoretical yield is 6 rings.
Explanation:
Theoretical yield is predicted or estimated value.
Jeweler used 2 sapphires for 1 ring
Then for each sapphire there will be =
rings are used
For 12 sapphire =
will be used
Out of 10 rings 6 rings with 2 sapphires will be made.
The theoretical yield is 6 rings.
This is considered a physical change because the water does not change its chemical properties - it is still water. It is simply just moving its shape such as gas form, liquid form, or solid form.
Answer:
illustrates ways things are similar and different
Explanation:
Above question is incomplete. Complete question is
<span>What is the missing number in the nuclear reaction 175 78 pt -- 4 2 He plus 76 Os?
....................................................................................................................
Solution:
Reaction involved in present nuclear event is
</span>175 78 Pt → 4 2 He + 76 Os
In above nuclear reaction, atomic mass number of Os is missing. The atomic mass number of Os = 175 - 4 = 171
Thus, complete nuclear can be written as
175 78 Pt → 4 2 He + 171 76 Os
Answer: A. Energy was absorbed
