What is the percent of O in<br> CO2?

What is the hybridization of the carbon atoms in 1,3-butadiene, h2c=ch-ch=ch2?

Natalija [7]

The main formula is as follow is explained in the attached file (please look at the examples)

the 1,3- butadiene is h2c=ch-ch=ch2, so we have

sp² sp² sp² sp²
h2c = ch - ch = ch2

<span>the hybridization of the carbon atoms is </span>sp² : trigonal planar

What is the energy of an electron in the hydrogen atom determined by?

mezya [45]

Answer:

The energy of a hydrogen atom's electron is determined by which principal quantum number n value corresponds to the energy state the electron occupies. where n=1,2,3,... is the quantum number that quantizes the energy levels. That is, they are discrete energy values proportional to 1n2 .

Dolomite is a mixed carbonate of calcium and magnesium. Calcium and magnesium carbonates both decompose upon heating to produce

Setler79 [48]

Answer:

72.03 %

Explanation:

Total mass of dolomite = 9.66 g

Let the mass of Magnesium carbonate = x g

The mass of calcium carbonate = 9.66 - x g

Calculation of the moles of Magnesium carbonate as:-

Molar mass of Magnesium carbonate = 122.44 g/mol
