The molar mass is what would you find on the periodic table and it is used in the mole conversions within chemistry. So the answer would have to be A: the mass in grams of one mole of a substance.
Answer:
Explanation:
Temperatur is proportional to volume so when temperature drops so does volume
<u>Answer:</u> The number of moles of is 0.05 moles.
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Molarity of solution = 0.10 mol/L
Volume of solution = 1 L
Putting values in above equation, we get:
The chemical reaction for the ionization of sodium sulfate follows the equation:
By Stoichiometry of the reaction:
2 moles of sodium ions are produced by 1 mole of sodium sulfate
So, 0.10 moles of sodium ions will be produced by = of sodium sulfate.
Hence, the number of moles of is 0.05 moles.
Answer:
A. Move to safe location
Explanation:
Plants and animals form the living community of the environment. Both of them share some of the common characteristics. Both are made of cells and they use energy for their growth and development. One of the differences between the two lies in the ability to move from one place to another. Animals have legs with which they can easily move from one place to another in search of food, shelter, and safety. While plants are unable to move as they are fixed in one place.
2 KMnO4 (aq) + 5 H2O2 (aq) + 3 H2SO4 (aq) → 5 O2 (g) + 2 MnSO4 (aq) + K2SO4 (aq) + 8 H2O (l)
