A catalyst will ALWAYS increase the reaction rate so C
Answer: B
Refer:
Because water molecules are polar, they interact with the sodium and chloride ions. In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes. This concept is often expressed as “Like dissolves like.
Explanation:
To delineate the the nature of the bonds that would be formed between the two elements, let us first write the electronic configuration of the two species;
Be = 2, 2
F = 2, 7
Beryllium is a metal with two valence electrons whereas fluorine is a halogen with seven valence electrons.
When Be loses two electrons it becomes isoelectronic with He;
Be → Be²⁺ + 2e⁻
Also, when fluorine gains an electron, it becomes isoelectronic with Ne;
F + e⁻ → F⁻
This loss and gain of electrons between the two elements creates an electrostatic attraction them and they enter into an electrovalent bond.
Hence;
Be²⁺ + 2F⁻ → BeF₂
E=hc/λ =6.626×10^-34×3 ×10^8 / 3×10^7 × 10^-9 = 6.626×10 ^-24J.
The neutral grain spirit is essentially known as rectified spirits or ethyl alcohol.
<h3>Meaning of
neutral grain spirit</h3>
neutral grain spirit can be defined as raw material that is very concentrated with alcohol used to produce strong alcoholic products.
neutral grain spirit as the name implies is neutral in nature that is it can be blended with any other alcoholic product.
In conclusion, The neutral grain spirit is essentially known as rectified spirits or ethyl alcohol.
