Answer:
Forming a problem requires the scientist to use creativity to imagine new solutions.
Explanation:
Albert Einstein remains a critically prominent figure who conducted remarkable, ground-breaking research that not only formed the foundations of modern physics but also strongly affected the scientific world. It is difficult to teach imagination but it can be harnessed and accepted. Nothing incites our imaginative impulses we love more than the prospect of immediate creative inspiration. And creativity hits its full potential when paired with the experience, insights, and skills people gained by questioning the real-life problems.
You could use another word for change can be variable witch means change and if you times the one two more times then you would get four because two time two would be four and times the one would be four.
Answer:
M HCl sln = 12.0785 M
Explanation:
- molarity (M) [=] mol/L
- %mm = ((mass compound)/(mass sln))*100
∴ mass sln = 100.0 g
∴ δ sln = 1.19 g/mL
∴ % m/m = 37 %
⇒ 37 % =((mass HCl/mass sln))*100
⇒ 0.37 = mass HCl / 100.0 g
⇒ 37 g = mass HCl
∴ molar mass HCl = 36.46 g/mol
⇒ mol HCl = (37 g)*(mol/36.46 g) = 1.015 mol
⇒ volume sln = (100 g sln)*(mL/1.19 g) = 84.034 mL = 0.084034 L
⇒ M HClsln = 1.015 mol/0.084034 L
⇒ M HCl sln = 12.0785 M
Answer:
2.17
Explanation:
To calculate pH using the hygrogen ion concentration we must use the following formula:
- log (H+) = pH
All we have to do now is plug in our hygrogen ion concentration and put it in our calculator.
- log (6.8 × 10⁻³) = 2.17
Don't forget proper figures for pH!
Answer:
Water- 9.982 grams
toluene-8.669 grams
chloroform - 14.832 grams
Explanation:
the units of density are listed as g/mL. So for every mL of substance you have, you will have that many grams.
Water- .9982g/mL * 10 mL
As you can see, the units of "mL" cancel each other out, leaving just the gram amount of water.
