So what ever that is in the jar dont spill out and it be no good thats why you keep a lid on things
Answer:
i would say red
Explanation:
im learning about this right now lol actually. <3
Answer:
You first need to construct a balanced chemical equation to describe the reaction:
KOH + HNO3 ---------> KNO3 + H2O
Work out the no. moles of HNO3 being neutralized:
Moles = Volume x Concentration = (25/1000) x 0.0150 = 0.000375 moles
From the balanced equation the molar ratio of KOH to HNO3 is 1:1 so you also need 0.000375 moles of KOH to neutralise the nitric acid
Now you can work out the volume of KOH required:
Volume = Moles/Concentration = (0.000375)/0.05 = 0.0075 dm^3 = 7.5 cm^3
Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.
<h3>Rate of reaction?</h3>
The term rate of reaction refers to how quickly or slowly a reaction proceeds. The surface area of solid reactants is an important factor that influences the rate of reactions when a solid reactant is involved.
Hence, Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.

The temperature of water as ice forms is very very low while when it begins to melt it gradually increases in temperature.
