The pair which consist of molecules having the same geometry is CH2CCI2 and CH2CH2.
Both of these molecules contain double bonds, which has sp^2 hybridization and they possess a trigonal planar geometry. In trigonal planar geometry, the molecule consist of three equally spaced sp^2 hybrid orbitals, which arranged at angle 120 degree.

If you were presented with 2 l of a 2 m sucrose stock solution, how many grams of sugar would be in a 100 ml aliquot?
lina2011 [118]

Answer;

68.46 g of sucrose in 100mL

Solution and explanation;

Given 2L of 2 mol/L sucrose solution

Moles = concentration x volume

Therefore; The number of moles in this solution is 2 L x 2 mol/L = 4 mol

The molecular mass of sucrose is 342.3 g/mol.

Mass = Moles × Molecular weight

Therefore the mass of sucrose in 2 L;

  = 4 mol x 342.3 g/mol = 1369.2g

but; 2L/20 = 100 mL

= 1369.2/20 = 68.46

Hence; you would have 68.46 g in 100 mL

Elements and molecules will always reemit the exact radiation that they
SashulF [63]
Elements/molecules will absorb a photon if energy, which will put them into an excited state. They will then emit that same energy back in order to come back down to their ground state energy.

When an isotope emits an alpha particle, its atomic number
Yuri [45]

Answer:

The atomic number of the isotope is reduced by 2 and atomic mass is reduced by 4.

Explanation:

Alpha particle is doubly ionized helium atom. The atomic mass of helium atom is 4 u and atomic number of helium atom is 2. The emission of alpha particle means doubly ionized helium atom will be released from the isotope.

Hence, the emission of the alpha particle will decrease the atomic mass by 4 and atomic number by 2.

Hence, option(a) is correct
