Answer:

(3) carbon atoms

Explanation:

2- butanol is a secondary alcohol containing C,H and O with a molecular formula: C4H10O and a structural formula: CH3CH2CH(OH)CH3

2- butene is an unsaturated hydrocarbon i.e. an alkene containing C and H only with a molecular formula: C4H8 and a structural formula:

CH3CH2CH=CH2

Based on the given options, the only common ground between 2-butanol and 2-butene is that both contain carbon atoms.

Catalyst, in chemistry, a substance that speeds up a reaction without itself being consumed. Enzymes are natural catalysts responsible for many important biochemical reactions.

Most solid catalysts are oxides, sulfides, halides of metals or metallic elements, and metalloid elements boron, aluminum and silicon. Gas and liquid catalysts are usually used in pure form or in combination with suitable carriers or solvents. Solid catalysts are usually dispersed in another material known as a catalyst support.

What is the maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light? The
Genrish500 [490]

Answer:The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

What is the total number of protons and neutrons in an atom called?
anzhelika [568]

This is called the Mass Number of the isotope of the atom.

Isotopes are different forms of the same atom. They have the same number of protons  but different number of neutrons.

Carbon-12 has mass number  12 as it has 6 protons and 6 neutrons.

Carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.

A 4.70 g of a C.H. compound was combusted in air to make 15.3 g of CO, and 4.70 g H.O. What is the empirical formula? Balance th
34kurt

Answer:

The empirical formula is C₂H₃

Explanation:

The empirical formula of a chemical compound is defined as the simplest positive integer ratio of atoms present in a compound.

The reaction of combustion for a CₐHₓ is:

CₐHₓ + (a+x/4) O₂ → a CO₂ + ˣ/₂ H₂O

The moles obtained are

15,3 g of CO₂ × \frac{1mol}{44,01g} = 0,3476 moles of CO₂≡moles of C

4,70 g of H₂O × \frac{1mol}{18,02g} = 0,2608 moles of H₂O × 2 = 0,5216 moles of H.

The ratio H:C is 0,5216/0,3476= 1,5. That means you have 1,5 H per 1C, that is the same than 3H per 2C. Thus, empirical formula is:

C₂H₃

I hope it helps!
