Answer:
The answer to your question: 0.7 M
Explanation:
Data
V of KOH = 90 ml
[KOH] = ?
V H2SO4 = 21.2 ml
[H2SO4] = 1.5 M
2KOH(aq) + H₂SO₄(aq) → K₂SO₄(aq) + 2H₂O(l)
Molarity = moles / volume
moles of H₂SO₄ = (1.5) (21.2)
= 31.8
2 moles of KOH -------------- 1 mol of H₂SO₄
x -------------- 31.8 mol of H₂SO₄
x = (31.8)(2) / 1
x = 63.8 moles of KOH
Molarity = 63.8 / 90
= 0.7 M
Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!
ideal gas law. but you are talking about moles of gas not miles
The flame test is a qualitative test used in chemistry to help determine the identity or possible identity of a metal or metalloid ion found in an ionic compound. If the compound is placed in the flame of a gas burner, there may be a characteristic color given off that is visible to the naked eye. And for the proof. The flame test provided evidence that specific atoms are present in compounds by the color of the flame. The metal atoms are what is responsible for the colors during the flame test. The color of the flame will be yellow-orange because Sodium (Na) is present in all the compounds that have a yellow-orange flame. Hope this helps! Mark brainly please!
The IUPAC names of the organic compounds would be as follows:
1. Methanol or 1-Methanol
2. Propan-2-ol or 2-Propanol
3. 2-MethylButane
4. 1-Hexanol
5. 1-Heptanol
<h3>Naming organic compounds</h3>
In the naming of organic compounds, some fundamental rules come into practice. Some of these rules include:
- The longest carbon chain, otherwise known as the parent chain, is considered.
- The substituents must be identified
- The parent chain should be named such that the substituents are located on the lowest-numbered carbons. Repeated substituents are named accordingly.
- Different substituents are named alphabetically and substituents with lower alphabets are considered for the lowest-numbered carbons.
Following these rules and more, the name of the organic compounds whose structures are shown in the image would be as follows:
- Methanol or 1-Methanol
- Propan-2-ol or 2-Propanol
- 2-MethylButane
- 1-Hexanol
- 1-Heptanol
