Answer:
aldehyde
Explanation:
Aldehydes are a large class of reactive organic compounds (R-CHO) having a carbonyl functional group attached to one hydrocarbon radical and a hydrogen atom.
So, when terminal alkynes, for example, 1-heptyne react on Hydroboration oxidation(i.e. disiamylborane followed by treatment with basic hydrogen peroxide), the formation of aldehyde occurs.
Answer:
The answer to the question is
Chlorine Cl₂
Explanation:
Graham's Law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of the molar mass
0.238 = 
Therefore M₁ = 4÷0.238² = 70.61
Hence the mass of the gas is 70.61, that is X₂ = 70.61 or the molar mass of the element X = 70.61÷2 = 35.308 ≅35.453 Hence the gas is chlorine Cl₂
Chemical equation of the reaction between citric acid and baking soda:
Ratios
Citric Acid Baking soda -> Sodium Citrate Water Carbon Dioxide
C6H8O7 CO2
1 mole 3moles
Molecular masses
Citric acid
6*12 + 8*1 + 7*16 = 192 g/mole
Carbon dioxide
12 + 2*16 = 44 g/mole
Proportion carbon dioxide / citric acid
3 * 44 g of carbon dioxide / 192 g of citric acid
132 g of carbon dioxide / 192 g of citric acid
13.00 g of citric acid * [132 g of carbon dioxide / 192 g of citric acid] = 8.94 g of carbon dioxide.
Answer: 8.94 grams.
Answer:
In this case the mass number would be 11.
Explanation:
The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons).
Atomic mass is the decimal number that is on the periodic table...
Boron's atomic mass is 10.81
