well according to what i know....headlights only let you see about 350 feet ahead...hope it helps :)
Triethanolamine has a formula of C6H15NO3. It is a polar molecule since the structure is unbalanced one side which makes it able to interact with water molecules. The central atom is N for this molecule. Hope this answers the question.
The mass ca(Oh)2 needed to produce 1.5 l of 0.25 solution is calculated as follows
find moles
=moles = molarity x volume
moles is therefore = 1.5 x 0.25 = 0.375 moles
mass = moles x molar mass
0.375mol x 74.09 g/mol = 27.78 grams
Answer:
Faster
number
reactants
increases
Explanation:
The rate of reaction refers to how fast or slow a reaction occurs. The rate of reaction is dependent on factors such as surface area, concentration, temperature, nature of reactants, catalyst etc.
The concentration refers to the amount of reactants present. When the acid is made more concentrated, its amount is increased. This increases the number of collisions between the acid particles and the marble chips ultimately leading to increase in the rate of reaction according to Arrhenius theory.
