The best way to dry is to let it air dry after washing it with soap and water
Since we have a hydrocarbon (CH4) plus Oxygen gas (O2) in the reactants and Carbon dioxide (CO2) and Water (H2O) we know that this type of reaction is considered a Combustion reaction.
Answer:
The answer to your question is letter c. Ca(NO₃)₂
Explanation:
Data
Ca(NO₃)₂ = 3.4 moles
Li₃PO₄ = 2.4 moles
Reaction
3 Ca(NO₃)₂ + 2 Li₃PO₄ ⇒ 6 LiNO₃ + Ca₃(PO₄)₂
Process
Calculate the proportion theoretical and experimental of reactants and compare these proportions.
Theoretical proportion
Ca(NO₃)₂ / Li₃PO₄ = = 1.5
Experimental proportion
Ca(NO₃)₂ / Li₃PO₄ =
As the experimental proportion is lower than the theoretical proportion we conclude that the amount of Li₃PO₄ increased in the experiment so the limiting reactant is Ca(NO₃)₂.
Given,
The specific heat capacity (c) of iron skillet is 0.449 J/ g °C.
Mass of iron skillet, m = 37 g
Temperature difference, T = (240-80)°C
=160 °C
Now using formula,
Heat (Q)= c * m * T
= 0.449 J/ g °C * 37 g * 160°C
= 2658 J
hence heat absorbed by 37g iron skillet when temperature rises form 80 to 240 degree Celsius is 2658 Joules.

Answer:
One mol is added to a solution of acids
One mol is added to a solution of base.
Explanation:
Titration is a process of adding one concentration of solution to another solution until the reaction neutralizes. In acid base titration the concentrated acid solution is titrated with concentrated base solution. Ph indicator is used to monitor the reaction. When reaction neutralizes it changes its color to pink indication that the reaction is completed.
