Answer:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Explanation:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Halogens are Soluble
Carbonates are Insoluble
This reaction DOES take place.
Remains the same because temperature can't change energy
Answer: Once the fingerprints are captured and described, judicial physicists use a categorization structure to label the ruling class. The three elementary mark on finger patterns is Whorl, Arch, and Loop. There are more intricate categorization methods that further decay the pattern to plain arches or make camp arches. Loops grant permission be branching or ulnar.
Answer:
b. 10 mL
Explanation:
First we <u>calculate the amount of H⁺ moles in the acid</u>:
- [H⁺] =

100 mL ⇒ 100 / 1000 = 0.100 L
- 1x10⁻⁵M * 0.100 L = 1x10⁻⁶ mol H⁺
In order to have a neutral solution we would need the same amount of OH⁻ moles.
We can use the pOH value of the strong base:
Then we <u>calculate the molar concentration of the OH⁻ species in the basic solution</u>:
- [OH⁻] =
= 1x10⁻⁴ M
If we use 10 mL of the basic solution the number of OH⁻ would be:
10 mL ⇒ 10 / 1000 = 0.010 L
- 1x10⁻⁴ M * 0.010 L = 1x10⁻⁶ mol OH⁻
It would be equal to the moles of H⁺ so the answer is b.
Answer:
2NaNO3+1PbO=1Pb(NO3)2+1Na2O
Explanation:
My chem teacher always had us make a T-chart for products and reactants on both sides to help you figure out balancing equations
