Answer:The rock forms large crystals
Explanation:
Ionic compounds are formed by the complete transfer of electrons between the atoms. The atom which gains electron(s) forms anion whereas loss of electron(s) results in the formation of cation. They are bonded to each other by electrostatic force of attraction between the negatively and positively charged atoms.
While writing the ionic chemical formula for binary ionic compound the rules are:
- Writing the chemical symbol of the metals and non-metals involved in the compound formation.
- The charge i.e. the absolute value of oxidation number of each metal is written on respective atoms.
- The charge i.e. the absolute value of oxidation number are cross-multiplied that is the charge of first ion becomes the subscript of second ion and vice versa.
Hence, in the writing of ionic chemical formulas, the value of each ion's charge is "crossed over" in the crossover rule.
Answer:
16kg/s
Explanation:
The formula for acceleration is [ a = f/m ] where f = force and m = mass
a = 4/0.25
a = 16
Best of Luck!
Explanation:
Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.
= k
where, k = rate constant
n = order of reaction
For the given reaction,
Hence, its rate will be as follows.
Rate =
Also, it is known that slowest step in a chemical reaction is the rate determining step.
Hence, for the given rate law correct reaction is as follows.
Step 1 : (slow)
Balancing this equation it becomes (slow)
Step 2: (fast)
