Answer:
136.36 mL
Explanation:
Here we have to use the dilution formula
From C1V1= C2V2
Where;
C1= initial concentration of the solution= 12.0 M
C2= final concentration of the solution= 2.20 M
V1 = initial volume of the solution= 25.0 ml
V2= final volume of the solution= ?????
Then recall;
C1V1=C2V2
V2 = C1V1/C2
Substituting values from the parameters given;
V2= 12.0 × 25.0 / 2.20
V2= 136.36 mL
Q=mcdeltaT. use this formula and find the answer.
Explanation:
The given compound is:
AlCl₃
- ionic formula - it is a combination between a metal and non - metal with an electronegativity difference greater than 0.7
- 3 chlorine atoms - from the compound, we see that the compound is made up of 1 aluminum atom and 3 chlorine atoms.
- Aluminum is the cation
- Chlorine is the anion
A cation is the positively charge specie and the anion is the negatively charged one.
Al³⁺ + 3Cl⁻ → AlCl₃
Answer:
A beach forms when waves store sand and rock along the shoreline. A few sea shores are comprised of rocks and stones. After some time, they are moved around smooth by the waves.
Explanation:
A beach is a geologic arrangement that is situated along a huge waterway, including lakes, streams, and seas. Sea shores are described by the presence of small bits of natural silt. The dregs might be made out of sand, rock, shell, green growth, or stones. Normal sea shores may take a large number of years to advance, a cycle that is the consequence of continually moving water that disintegrates the land situated around its edge. Basically, rocks or coral reefs situated off the shore are worn out by moving waves. Moreover, streams and rainwaters may dissolve rocks found further inland. These dregs are stored along the coastline, framing a sea shore.
