Hi sorry
I don’t know
but maybe next time
Options:
conduct an experiment
form a hypothesis
draw a conclusion
state the cause
Answer:
'<u>State the cause'</u> is not part of the scientific method.
Explanation:
The scientific method has three wholistic steps:
- Test the hypothesis
- Make observations from the experiment to the hypothesis
- Draw a conclusion or prediction from the experimental results.
A cause is neither a scientific term nor is it part of the processes of experimentation.
I hope this was helpful.
Answer:
= 9,593.1 Joules
Explanation:
Heat absorbed by water is equivalent to heat released by copper.
Heat absorbed is given by;
Q = mcΔT
where m is the mass, c is the specific capacity and ΔT is the change in temperature.
Therefore;
Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.
Heat absorbed by water = 45 g × 4.18 J/g°C × 51
= 9,593.1 Joules
Therefore, the heat released by copper is 9,593.1 Joules
Precipitation occurs when the product of the ion concentration exceeds the Ksp.
