the heat of reaction for a chemical reaction
Answer:
An evenly distributed, uniform mixture is called a homogeneous mixture.
Explanation:
Q1. They are highly reactive. Q2. High reactivity, nonmetallic. Q3. Oxygen has an ion charge of -2. Q4. LiCl I believe. Q5. How electrons are shared. Q6 1. Q7. Share 2 valence electrons, I believe.
Answer:
The pH range, reaction rate, accuracy and solubility are affected by the temperature.
Explanation:
Hello,
Temperature is factor affecting how solutions behave, thus, it could modify the pH range (change in color values) for an indicator in the presence of a base or an acid, since the kinetics behind the change of color is modified maybe decreasing or increasing the aforesaid range. Next, temperature usually increases the reaction rate, that's why the change in color could become faster or out of the proper change range. Then, in titration we use temperature-sensitive glassware which could expand due to high temperatures and subsequently turning out into wrong measurements. Finally, solubility is affected by the temperature, since the molecules are allowed to interact more effectively, that's we must make sure that they're completely dissolved at room temperature while titrating.
Best regards.
