The answer to your question is "carbon dioxide from combustion"
A change from physical change into chemical change not sure hope this helps
Answer:
There are three possible chemical equations for the combustion of sulfur:
- 2S (s) + O₂ (g) → 2SO (g)
- 2S (s) + 3O₂ (g) → 2SO₃ (g)
Explanation:
<em>Combustion</em> is a reaction with oxygen. The products of the reaction are oxides, and energy is released in the form of heat and light.
<em>Sulfur</em> iis a nonmetal, so the oxide formed is a nonmetal oxide.
The most common oxidation numbers of sulfur are -2, + 2, + 4, and + 6.
The combination of sulfur with oxygen may be only with the positive oxidation numbers (+2, + 4, and +6).
Then you have three different equations for sulfur combustion:
<u>1) Oxidation number +2:</u>
Which when balanced is: 2S(g) + O₂(g) → 2SO(g)
<u>2) Oxitation number +4:</u>
That equation is already balanced.
<u>3) Oxidation number +6:</u>
Which when balanced is: 2S(s) + 3O₂(g) → 2SO₃(g)
Body fossils are exactly what they sound like of the body which includes bones,shell, teeth, skin impression,etc.
Trace fossils are fossils such as footprints, corpolites, etc, which are traces of prehistoric animals
Answer:
The answer to your question is 97 ml
Explanation:
Data
volume = ? ml
concentration = 1.01 M LiNO₃
mass = 6.63 g
Process
1.- Calculate the molecular weight of LiNO₃
LiNO₃ = (1 x 6.94) + (1 x 14) + (16 x 3)
= 6.94 + 14 + 48
= 69 g
2.- Calculate the moles of LiNO₃
69 g ------------------ 1 mol
6.63 g --------------- x
x = (6.63 x 1) / 69
x = 0.096 moles
3.- Calculate the volume
Molarity = moles / volume
-Solve for volume
Volume = Molarity x moles
-Substitution
Volume = 1.01 x 0.096
-Result
Volume = 0.097 l or 97 ml
