Answer:
The answer to your question is below
Explanation:
Data
Demonstrate pH = -0.301
concentration = 2 moles/L
Formula
pH = -log [H⁺]
Process
1.- Calculate the [H⁺] concentration
[H⁺] = 2 moles/L = 2 M2.- Substitute in the formula
pH = -log[2]
simplification
pH = -0.301
2.- Conclusion
It is an acidic solution
Answer:
Moles to Grams caco3
1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
Answer: Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock.
Explanation: This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Answer:
12.9 m³ is the new volume
Explanation:
As the temperature keeps on constant, and the moles of the gas remains constant too, if we decrease the pressure, the volume will increase. If the volume is decreased, pressure will be higher.
The relation is this: P₁ . V₁ = P₂ . V₂
1 atm . 0.93m³ = 0.072 atm . V₂
0.93m³ .atm / 0.072 atm = V₂
V₂ = 12.9 m³
In conclusion and as we said, pressure has highly decreased so volume has highly increased.
Answer: 30 m/s
Explanation:
Use the first kinematic equation for linear motion
