Answer:
The false statement is B.
Explanation:
When the temperature in a reaction increases, the rate of this reaction increases.
It means that it would be more probably to each molecule in the system collides but that does not mean that the reaction will happen faster because there is other factors that affect the velocity of the reaction, such as concentration of reactants, presence of catalyst, and activation energy.
Also, the nature itself of the reaction can affect the velocity, due to some of chemistry reactions occur instantaneously without increasing the temperature and in the case you increase the temperature the reaction will not occur quickly.
On the other hand, the size of the particle will affect the rate due to smaller particles are able to move faster than larger ones under high Temperature.
To have the all three scales set at zero.
Answer:
2HI + K2SO3=>2KI+H2SO3
Explanation:When aqueous hydroiodic acid and aqueous potassium sulfite are mixed the products obtained are potassium iodide and sulfurous acid.Both reactants are ionic compounds and they undergo double replacement reaction.In a double replacement reaction the parts of the ionic compounds are changed.The product is obtained by combinig cation of one compound with anion of other compound.so in above reaction sulfurous acid is obtained which is in gaseous form and potassium iodide is an ionic compound.
Answer:
Periods have consecutive atomic number as they are in a row and groups are vertical meaning they are in a column and groups have similar properties
Well, figures for efficiency vary a lot, but according to Bicycling Science it’s lubrication that matters most – lubing a dry chain can add 5% to the efficiency.
More interestingly (and I hadn’t read this bit in the book before) it varys a lot depending on gear ratio – bottom gear (22-28) is 99% efficient, top gear (42-11) is 88%. That’s a big difference
