The answer is 62.00 g/mol.
Solution:
Knowing that the freezing point of water is 0°C, temperature change Δt is
Δt = 0C - (-1.23°C) = 1.23°C
Since the van 't Hoff factor i is essentially 1 for non-electrolytes dissolved in water, we calculate for the number of moles x of the compound dissolved from the equation
Δt = i Kf m
1.23°C = (1) (1.86°C kg mol-1) (x / 0.105 kg)
x = 0.069435 mol
Therefore, the molar mass of the solute is
molar mass = 4.305g / 0.069435mol = 62.00 g/mol
The statement that best describes waves is B. Waves cannot propagate without a medium
sp2 Hybridization. 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>How do you describe hybrid orbitals?</h3>
A hybrid orbital is an orbital formed by the combination of two or more atomic orbitals. The resulting orbital has a different shape and energy than the component orbitals that form it. Hybridization is used to model molecular geometry and to explain atomic bonding.
<h3>What is the hybridization of the s atom?</h3>
The middle S atom containing the 5 valence atomic orbitals is basically hybridized to form five sp3d hybrid orbitals. In 2P-orbitals, four hybrid orbitals are overlapped and the fifth one contains a lone pair.

Answer:
increasing wavelength increases frequency
Explanation:
Answer:
The resources needed for renewable energy is not always available.
Explanation:
The main renewable resourced that are used are
Wind
Solar
Bio mass
Small hydro
The most common thing about these resourced are their uncertain nature. The uncertain nature that these resourced contain makes if unreliable for a stand alone power source.
