Answer:
phosphorus - least similar to barium
beryllium - most similar to barium
Explanation:
The formula of the chloride formed between barium and chlorine is BaCl2.
Barium is a metallic element and has the valency of +2. Beryllium is also a group two metal with a valency of +2. Hence the compound formed between beryllium and chlorine is BeCl2
Phosphorus is a nonmetal and forms a completely different chloride from BaCl2. The chloride of phosphorus is PCl5 and PCl3. These are least similar to BaCl2
Two compounds containing six carbon atoms on treatment with <span>either with BH</span>₃<span> in THF followed by H</span>₂<span>O</span>₂<span> /OH</span>⁻<span> (OR) with H</span>₂O <span>/ Hg</span>²⁺<span> / H</span>₃O⁺ gives the same products.
The two alkynes, their two different types of reactons and products are given below,
Mole to Mole.
Assuming you're referring to converting in general, there must always be a mole to mole conversion.
Gram to gram would be incorrect as you must have a molar conversion in order to do so.
Gram to mole would be incorrect because that would leave out molecular conversions which would require three steps rather than two.
Mole to molecule is incorrect as it leaves out grams, depending on the circumstances and equation provided.
Thus, through process of elimination, mole to mole is the correct answer.
Hope this helps!
Answer:
The answer to your question is: yield = 56.27%
Explanation:
Data
CH3CH2CH2CH2OH (l) → CH3 CH2CH2CH2Br
18.54 ml 1-butanol 15.65 g of 1-bromobutane
% yield = ?
density = 0.81 g/ml
MM = 74 g 1- butanol
MM = 137 g 1-bromobutane
Process
Calculate mass of 1- butanol
density = mass/volume
mass = density x volume
mass = 0.81 x 18.54
mass = 15.02 g of 1-butanol
Theoretical yield
74 g of 1- butanol ----------------- 137 g of 1-bromobutane
15.02 g of 1- butanol ------------- x
x = (15.02 x 137) / 74
x = 27.81 g of 1-bromobutane
% yield = experimental yield / theoretical yield x 100
% yield = 15.65 / 27.81 x 100
% yield = 56.28
Answer:atoms involved in reaction. Mass remains same in reaction
Explanation: hug would be fine!
