The difference is the amount of oxygen in the compound
Static. Is the bond if u need 2 know
The combination of the of two or more elements is known as a compound.
A homogenous mixture has a uniform composition all throughout. They are
similar in terms of the amount of composition present in a solution. For
example, oxygen is diatomic, O2. So oxygen is a compound because it has 2
elements combined in it. It is also a homogenous mixture if there are a lot of
O2 gases present in let’s say tank. They only differ in the place where they
are present. A compound is a representation of one molecule whereas a
homogenous mixture is present in a a solution.
Answer:
Chemoautotrophs
Explanation:
Autotrophs are groups of organisms that are capable of manufacturing their own food (organic molecules) through the fixation of carbon dioxide. There are two types of autotrophs:
- <em>Photoautotrophs fix carbon dioxide by using light as the energy for driving the process.</em>
- <em> </em><em>Chemoautotrophs f</em><em>ix carbon dioxide by using energy from the oxidation of inorganic molecules such as magnesium, or sulfur.</em>
Chemoautotrophs usually inhabit extreme environment such hot vents, deep sea, etc.
V( H₂SO₄) = 25.0 mL in liters = 25.0 / 1000 = 0.025 L
M(H₂SO₄) = ?
V(NaOH) = 50.0 mL = 50.0 / 1000 = 0.05 L
M(NaOH) = 0.150 M
number of moles NaOH :
n = M x V
n = 0.150 x <span> 0.05
</span>
n = 0.0075 moles of NaOH
H₂SO₄(aq) + 2 NaOH(aq) = Na₂SO₄(aq) + 2 H₂O(l)
1 mole H₂SO₄ ---------- 2 mole NaOH
? mole H₂SO₄ ---------- 0.0075 moles NaOH
moles = 0.0075 * 1 / 2
= 0.00375 moles of H₂SO₄
M(H₂SO₄) = n / V
M = 0.00375 / <span> 0.025
</span>= 0<span>.15 M
</span>
hope this helps!
