Each​ year over 100,000 new organic compounds are produce
galben [10]3 years ago
6 0

Answer:

100, 000

Explanation:

An organic compound is a chemical compound in which one or more atoms of carbon are covalently bonded to atoms of other elements, majorly that of either hydrogen, oxygen or nitrogen. Because of the vast importance and uses of organic compounds, they can be synthesised from petrochemicals to meet up the demands..

Why does water have a much higher boiling point than methane even though water (H20) and methane (CH4) molecules are approximate
PSYCHO15rus [73]

Answer:

Water has a higher boiling point because the hydrogen bonds that form water molecules are stronger than the Van der Waals interactions among methane molecules, therefor more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.

What is the pH of a 0.28 M solution of ascorbic acid
Nady [450]

Hey there!

Values Ka1 and Ka2 :

Ka1 => 8.0*10⁻⁵

Ka2 => 1.6*10⁻¹²

H2A + H2O -------> H3O⁺  + HA⁻

 Ka2 is very less so I am not considering that dissociation.

Now Ka = 8.0*10⁻⁵ = [H3O⁺] [HA⁻] / [H2A]

lets concentration of H3O⁺  = X then above equation will be

8.0*10−5 = [x] [x] / [0.28 -x

8.0*10−5 = x² /  [0.28 -x ]

x² + 8.0*10⁻⁵x  - 2.24 * 10⁻⁵

solve the quardratic equation

X =0.004693 M

pH = -log[H⁺]

pH = - log [ 0.004693 ]

pH = 2.3285

Hope that helps!

If you know your acid concentration is .650 M and you used 15.00 mL, what was the concentration of the base if you needed 35.5 m
Anvisha [2.4K]

Answer:

0.29

Explanation:

Since the name of the acid (and the equation) is not given, you must assume that it is a 1:1 ratio. Use equation: volume of acid x molarity of acid = volume of base x molarity of base (when the ratio is 1:1).

What mass of zinc is needed to react with 23.1g of phosphoric acid according to the following equation?
Hunter-Best [27]

23.01 g of zinc (Zn)

Explanation:

We have the following chemical reaction:

3 Zn + 2 H₃PO₄ = 3 H₂ + Zn₃(PO₄)₂

number of moles = mass / molar weight

number of moles of phosphoric acid = 23.1 / 98 = 0.236 moles

Taking in account the chemical reaction, we devise the following reasoning:

if           2 moles of H₃PO₄ are reacting with 3 moles of Zn

then      0.236 moles of H₃PO₄ are reacting with X moles of Zn

X = (0.236 × 3) / 2 = 0.354 moles of Zn

mass = number of moles × molar weight

mass of Zn = 0.354 × 65 = 23.01 g
