Answer is: True.
Example for p<span>olyhydroxyl alcohol is glycerol.</span>
Glycerol (1,2,3-Propanetriol, glycerine<span> or glycerin) is a simple polyol (it has three hydroxyl group) compound with formula (OH-CH</span>₂-CH(OH)-CH₂OH or C₃H₈O₃).
The glycerine <span>backbone is found in
all lipids known as triglycerides. (ester derived from glycerol and three fatty acids).
Glycerol is soluble in water and it is hygroscopic.</span>
Answer:
Positively charged ions are called cations; negatively charged ions, anions
We'll make this a bit simpler.
1 mile = 1.60934km
90.0 million miles.
9.0 x 10^7 miles * (1.60934km / 1 mile) * (1000m / 1km) = 7.70x10^79 m
Answer:
There will be 525.2 grams of K3N produced
Explanation:
Step 1: Data given
Number of moles of potassium oxide ( K2O) = 6 moles
Magnesium nitride (Mg3N) = in excess
Molar mass of K3N = 131.3 g/mol
Step 2: The balanced equation
Mg3N2 + 3K2O → 3MgO + 2K3N
Step 3: Calculate moles of K3N
The limiting reactant is K2O.
For 1 mol Mg3N2 consumed, we need 3 moles of K2O to produce 3 moles of MgO and 2 moles of K3N
For 6 moles K2O we'll have 2/3 * 6 = 4 moles of K3N
Step 4: Calculate mass of K3N
Mass of K3N = moles K3N * molar mass K3N
Mass of K3N = 4 moles * 131.3 g/mol
Mass of K3N = 525.2 grams
There will be 525.2 grams of K3N produced
