Answer:
Answer is 2nd
Explanation:
some energy is transformed into mass
Assuming the water is present at 20 °C, the solubility of barium chromate is 0.2275 mg/100 mL
Converting this to mg/L, we get:
2.275 mg/L
Converting this value again, to grams per liter, we get:
0.002275 g/L
To dissolve one gram, we require:
1/0.002275 = 439.56044
440 liters of water.
Ribosome would be considered a factory “worker” as they *produce* proteins!
Answer:
Electrons
Explanation:
According to the Valence Shell Electron Pair Repulsion Theory (VSEPR), the geometry of a molecule depends on the number of electron pairs (regions of electron density) on the central atom of the molecule. Electron pairs on the valence shell of the molecule tend to position themselves as far apart in space as possible to minimize repulsion between them. Hence, the orientation of these electron pairs is the ultimate determinant of the observed geometry of a molecule.
Lone pairs of electrons cause more repulsion than bond pairs of electrons on the central atom of a molecule. Hence when the central atom of a molecule contains lone pairs of electrons, the molecular geometry is usually distorted from the expected geometry on the basis of VSEPR theory.
Hence, electrons are the subatomic particles which are responsible for any change in the observed molecular geometry of a molecule.
