Answer:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH).
I hope what I just explained is enough .
Answer:
Bowl of clear chicken broth
Explanation:
A bowl of clear chicken broth is a heterogenous mixture.
- A heterogenous mixture is one in which the constituents exists in at least two different phases.
- A chicken broth is a heterogenous mixture which exists in the liquid - solid state.
- The broth is made up of simmered meat, vegetables and other recipes together.
Such mixtures can be:
- Gas - liquids mixtures
- Liquid - solid mixtures
- Gas - solid mixtures
A broth is an extract from cooking chicken. Some vegetables and extract are mixed together in a nutritious blend.
Answer:
Mass of chlorine = 47.22 g
Explanation:
Given data:
Mass of sodium = 30.5 g
Mass of chlorine= ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Number of moles of Na:
Number of moles = mass/molar mass
Number of moles = 30.5g/ 23 g/mol
Number of moles = 1.33 mol
Now we will compare the moles of Cl
₂ with Na from balance chemical equation.
Na : Cl
₂
2 : 1
1.33 : 1/2×1.33 = 0.665 mol
Mass of chlorine gas:
Mass = number of moles × molar mass
Mass = 0.665 mol × 71 g/mol
Mass = 47.22 g
Answer:
A fire extinguisher
Explanation:
A lab station usually contains equipment for the people working at the station to use. However, most rooms will only have one fire extinguisher for the whole room meaning it would most likely be located somewhere that is easy to access by all and not just a singular lab station.
~Hope this Helps!~
