Molar mass of sulphur dioxide ( SO2) = 64.066 g/mol
Molar mass of  water ( H2O ) = 18.0 g/mol

process:

2 H2S + 3 O2 --> 2 H2O + 2 SO2
<span>
2 * 18 g H2O --------------> 2* 64.066 g SO2
72.0 g H2O ----------------> mass of SO2

mass of SO2 =   72.0 *  2 * 64.066 / 2 * 18

mass of SO2 = 9225.504 / 36

mass of SO2 = 256.264 g

1 mole --------------> 64.066 g
mole SO2 ----------> 256.264

mole SO2 = 256.264 / 64.066

= 4 moles of SO2

hope this helps!.

Answer is: pH of barium hydroxide is 13.935.
Chemical dissociation of barium hydroxide in water:
Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻(aq).
c(Ba(OH)₂) = 0.43 M.
V(Ba(OH)₂) = 100 mL ÷ 1000 mL/L = 0.1 L.
n(Ba(OH)₂) = 0.43 mol/L · 0.1 L.
n(Ba(OH)₂) = 0.043 mol.
From chemical reaction: n(Ba(OH)₂) : n(OH⁻) = 1 : 2.
n(OH⁻) = 0.086 mol.
c(OH⁻) = 0.86 mol/L.
pOH = -logc(OH⁻).
pOH = 0.065.
pH = 14 - 0.065 = 13.935.

Which of the following is an example of a combustion reaction?
Alexus [3.1K]

Answer:

C) Lighting a matchstick

Explanation:

Mixing an acid and base will cause a neutralization reaction, a type of double displacement.

Photosynthesis is just a series of chemical reactions, but don't deal with the use of O2, but rather it's creation.

Reacting sodium and chlorine would make NaCl in a synthesis reaction.

What is meant when it is stated that WATER can ""Ionize"" to a certain extent? What are the products that are formed when water
never [62]

Answer:

Ionization is defined as the process by which the atoms accept or donate electrons and form positively or negatively charged species, called ions.

The ionization of water is known as the self-ionization or autoionization of water. This process involves the deprotonation of a water molecule and protonation of another water molecule to give hydroxide ion and hydronium ion, which exist in the state of chemical equilibrium.

H₂O + H₂O ⇌ H₃O⁺ + OH⁻

The pH of pure water is 7, neutral.

You put 31.0 g of ice in your mouth, and it completely melted to water and its
Leona [35]

During the melting of ice in the mouth, the mouth loses heat and feels colder.

<h3>What is the heat change that occurs in melting?</h3>

Melting is the process by which when a solid absorbs heat from the surroundings, it changes to liquid.

Therefore, the melting of a solid is an endothermic process.

In the system of ice melting in the mouth, the ice molecule absorbs heat energy from the mouth in order to melt.

Similarly, when the temperature of the water rose to 10.0 degrees, the water at 0.00 degrees absorbs heat from the mouth.

Therefore, the mouth loses heat and feels colder.

In conclusion, the melting of ice involves ice absorbing heat from the surroundings.
