(a)- Time
(b)- Heat produced(i guess)
(c)- Material
this is what I think, hope it helps
It is a covalent bond. Whenever a compound uses such suffixes like mono, di, tri, tetra, and so on, it is a covalent compound- thus having covalent bonds.
The heat cause 300g water temperature increase from 20 to 26 celcius. The heat transferred would be: 300g * (26 °C -20 °C) *4.2 joule/gram °C= 7560J
The unknown substance is added to the water, so its final temperature should be the same as the water. The calculation would be:
7560J= 124g * (100-26)* specific heat
specific heat= 7560J / 124g / 74 °C= 0.8238 J/gram °C
Answer:
The answer is the Sodium Chloride.
Explanation:
A solute is the minor component in a solution, dissolved in the solvent, and the sodium is being dissolved in water ( or the solvent).
