Answer:
Explanation:
A1. Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.
A2. The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. ... For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules
A3. Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately.
Answer:
temperature of the reaction vessel
Explanation:
temperature of the reaction vessel
Answer:
3: Lactone
Explanation:
Lactones are defined as carboxylic esters that contain the structure (−C(=O)−O−) which is essentially showing that an ester has now become part of the chemical structure of the ring.
Thus, looking at the question, it has the structure as defined in Lactones.
Thus, we can say that the compound is a Lactone.
Answer:
This solution has a volume of 98.4 mL
Explanation:
Step 1: Data given
Molarity of AgClO4 solution = 1.27 mol/L
Number of moles AgClO4 = 125 mmol = 0.125 mol
Molar mass of AgClO4= 207.32 g/mol
Step 2: Calculate volume of the 1.27 M solution
Molarity = moles / volume
Volume = moles / molarity
Volume = 0.125 moles / 1.27 mol /L
Volume = 0.0984 L = 98.4 mL
This solution has a volume of 98.4 mL
The valence orbitals of a central atom surrounded by three regions of electron density consist of a set of three sp2 hybrid orbitals and one unhybridized p orbital.
<h3> Is Nitrosyl fluoride polar or non polar?</h3>
The affinity for electrons between the two atoms will keep them together, resulting in the sharing of electron density. In the case of Nitryl fluoride, The N-F bond is polar, acting as a dipole with a partial positive charge on the nitrogen atom and a partial negative charge on the fluorine atom, respectively.
<h3>Is Nitrosyl fluoride a gas?</h3>
Nitryl fluoride, NO2F, is a colourless gas and strong oxidizing agent, which is used as a fluorinating agent and has been proposed as an oxidiser in rocket propellants (though never flown).
