Answer:
All ionic compounds with alkali metals are soluble.
Explanation:
Certain elements always form soluble substances. Most of those elements are alkali metals/group 1 metals.
Answer:
1.6 × 10³ s
Explanation:
Let's consider the following generic reaction.
A → B
The rate law is:
![rate=k \times [A]^{m}](https://tex.z-dn.net/?f=rate%3Dk%20%5Ctimes%20%5BA%5D%5E%7Bm%7D)
where,
rate is the reaction rate
k is the rate constant
[A] is the molar concentration of the reactant A
m is the reaction order
When m = 1, we have a first-order reaction. We can calculate the half-life for this reaction using the following expression.
Answer:
There must be an equal amount of each element on both sides of the equation.
Hope this helps
good luck
Answer:
camphor sublimates salt is soluble in water while sand does not sublime and does not dissolve in water you first heat the mixture in a beaker covered with a watch glass camphor will then accumulate on the watch glass then you dissolve the remaining mixture of sand and salt salt will dissolve forming a salt solution then you filter using a filter paper and a beaker the residue on the filter paper is sand while the filtrate is salt solution you then heat the salt solution so that it can evaporate leaving salt particles thus you will have obtained salt sand and camphor
