Answer:
Flavouring agent 2-Butanol, or sec-butanol, is an organic compound with formula CH3CH(OH)CH2CH3.
Mechanical energy = mass x acceleration due to gravity x height
= 1x9.8x10 = 98J
Answer is: this is synthesis reaction.<span>
</span>Chemical reaction: Ba + F₂ → BaF₂.
Synthesis reaction<span> is a type of reaction in which multiple reactants combine to form a single product.
</span>In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
The outer electrons of an element are called the valence electrons. They help make an element stable.
Cesium : 1 valence electron<span>.
Magnesium : 2 valence electrons</span>
