5.2 km to mm.
1km = 1000m
= 5.2 * 1000m.
=5200 m. 1m = 1000mm
= 5200 * 1000mm
= 5200000 mm
Answer:
The term conclusion best illustrates the given statement.
Explanation:
Conclusion refers to a decision or judgment that can be acquired by reasoning. From the observation mentioned in the given table:
1. The steel, aluminum, and bronze took 27, 45 and 80 seconds to dissolve small section of wax, this signifies that more time will be needed by them to transfer heat to the food while cooking. Thus, food will take more time to cook in them.
2. Copper consumed less time, that is, 15 seconds to melt the section of wax than the other metal pots, which signifies that it is a good conductor of heat than the others. Thus, the copper pot would be good for cooking food briskly.
After evaluating the results and observations in an experiment, the conclusion was made that pots made of copper are best for cooking foods.
Answer:
Explanation:
We can use the Arrhenius equation to relate the activation energy and the rate constant, k, of a given reaction:
k=Ae−Ea/RT
In this equation, R is the ideal gas constant, which has a value 8.314 J/mol/K, T is temperature on the Kelvin scale, Ea is the activation energy in joules per mole, e is the constant 2.7183, and A is a constant called the frequency factor, which is related to the frequency of collisions and the orientation of the reacting molecules.
Both postulates of the collision theory of reaction rates are accommodated in the Arrhenius equation. The frequency factor A is related to the rate at which collisions having the correct orientation occur. The exponential term,
e−Ea/RT, is related to the fraction of collisions providing adequate energy to overcome the activation barrier of the reaction.
Answer:
Explanation:
Concentration: i is defined as the mole per litre.
mole=0.15
volume=400 ml=0.4 litre
