Hello!
The answer is: Al2S3(s)+6H2O(l)→2Al(OH)3(s)+3H2S(g)
Why?
Balancing equations is the process where we look for an equal number atoms for each element on both sides of a chemical reaction (reactants and products) in order to satisfy the Law of Conservation of Mass, which states that the mass is equal before and after the reaction.
So, we have to check the number of atoms for both sides of the reaction:
Reactants:
Al=2 atoms
S= 3 atoms
H= 2 atoms
O = 1 atom
Products:
Al = 2 atoms
O = 6 atoms
H = 6 + 6 atoms = 12 atoms
S= 3 atoms
So, we can see that there is a difference between the number of atoms of Hydrogen, there are 2 atoms for the reactants and 12 for the products, for the Oxygen we can see that there is just 1 atom for the reactants and 6 for the products.
To adjust the number of atoms of Hydrogen and Oxygen, we just need to multiply the compound by 6 (H2O)
Al2S3(s)+6H2O(l)→2Al(OH)3(s)+3H2S(g)
Therefore, we have the same number of atoms for each element on both sides of the chemical reaction.
Have a nice day!
Answer:
150g
Explanation:
Assuming they are ideal gases at the same temperature and pressure, equal moles of gasses have equal volume. IN this case, if we have 10g of hydrogen gas, that is 5 moles of H2 gas. That means 5 moles og NO2 will occupy the same volume which is 5*(14.0 + 16.0*2) = 230 g
Answer:
5.3%
Explanation:
Let the volume be 1 L
volume , V = 1 L
use:
number of mol,
n = Molarity * Volume
= 0.8846*1
= 0.8846 mol
Molar mass of CH3COOH,
MM = 2*MM(C) + 4*MM(H) + 2*MM(O)
= 2*12.01 + 4*1.008 + 2*16.0
= 60.052 g/mol
use:
mass of CH3COOH,
m = number of mol * molar mass
= 0.8846 mol * 60.05 g/mol
= 53.12 g
volume of solution = 1 L = 1000 mL
density of solution = 1.00 g/mL
Use:
mass of solution = density * volume
= 1.00 g/mL * 1000 mL
= 1000 g
Now use:
mass % of acetic acid = mass of acetic acid * 100 / mass of solution
= 53.12 * 100 / 1000
= 5.312 %
≅ 5.3%
The fermentation reaction is a biochemical reaction which involves a microorganism consuming a substrate (Carbon -source) and in order to produce several products such as alcohol, proteins, amino acids, biogas etc.
The most common reactant/substrate for a fermentation reaction is sugar, specifically glucose and the most common product is alcohol. If the fermentation process is aerobic in nature, then a oxygen is also required as reactant. By products include carbon dioxide, sulfur oxides etc.
Answer:
an anion
Explanation:
since it lost a proton..it now has 3 protons and four electrons and possesses a minus charge since it is no longer neutrally charged..this minus charge makes it an anion
