Explanation:
Initial temp = 28 °C
Final Temp = ?
Heat = 184 J
mass = 5 g
c = 4.184 joule/gram °C
The relationship between these parameters is given by the equation;
H = mCΔT
ΔT = H / mC
ΔT = 184 / 5(4.184)
ΔT = 184 / 20.92
ΔT = 8.8 °C
ΔT = Final Temp - Initial Temp
Final Temp = Initial Temp + ΔT
Final Temp = 28°C + 8.8 °C
Final Temp = 36.8°C
Do you have choices because i have an idea
Not a chemical combination. A mixture can be easily separated
<span> Scientific reasoning consists of observation, forming a workable hypothesis and arriving at a conclusion. Almost without exception major scientific discoveries were made and are being made today based on these same precepts. It only seems logical when an individual makes a difficult decision he/she will apply all or part of these processes. Let;s say that you want to make someone;s acquaintance to possibly become serious. Certainly, you would begin by quietly observing them, then you might make a hypothesis, "This person might make a good companion for me." Then in your conclusion you would test your hypothesis and proceed as directed. THis may be a bit simplistic, and I hope that it helps.</span>
Answer:
Their valence electrons/properties
Explanation:
Elements in the same group of the periodic table have the same amount of valence electrons, which determines how they bond with other elements in other groups. This also determines their properties such as their reactivity. Since Li, Na, and K are in the same group, they must have similar properties and the same amount of electrons in their outermost shell.
