<span>According to crystal field strength, the Cl ligand results in the longest d-d transition when coordinated with Ti(III) due to its classification as a weak field ligand that causes minimal d orbital splitting.</span>
Answer:
(C) The average speed of molecules in ethane is the same as that of propanol.
Explanation:
In gas behavior, temperature is directly linked with speed. At a constant temperature, speed remains consistent. Also, we understand that ideal gases exhibit uniform behavior, irrespective of their type.
<span>Quarks exist inside protons and neutrons but are not components of electrons.
Quarks are subatomic particles that possess mass and fractional (non-integer) electric charge.
Protons and neutrons are composed of quarks, whereas electrons are not, since electrons are considered energy carriers with charge rather than massive matter. Because quarks have mass, they cannot be part of electrons.</span>
To find the mass of oxygen in the specified compound, we require the molar mass for both the compound and oxygen. We also establish the relationship between the number of moles of oxygen per mole of the substance. The calculation proceeds as follows:
90.0 g ( 1 mol / 86.91 g ) ( 1mol O / 1 mol Cl2O) ( 16 g / 1 mol ) = 16.57 g O
Answer:
To lower the temperature of the solution from 25.0°C to 5.0°C, it is necessary to use 35.2g of NH₄NO₃ for every 100.0g of water.
Explanation:
In order to cool down the solution, we need:
4.184 J/g°C × (5.0°C - 25.0°C) × (100.0g + X) = -Y
8368 J + 83.68 J/gX = Y (1)
Here, x represents the grams of NH₄NO₃ required, and Y represents the energy needed to remove heat.
Furthermore, the energy Y becomes:
Y = 25700 J/mol ×
X
Y = 321 J/g X (2)
Substituting (2) into (1)
8368 J + 83.68 J/g X = 321 J/g X
8363 J = 237.32 J/gX
X = 35.2g
This means 35.2g of NH₄NO₃ must be used for every 100.0g of water to achieve a temperature decrease from 25.0°C to 5.0°C.
