No the maximum number of electrons for "4p" is 6 so there can't be a 4p7
Answer: b suspension
a suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation . The particles may be
visible to the naked eye, usually must be larger than one micrometer , and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out. A suspension is a heterogeneous mixture in which the solute particles do not dissolve , but get suspended throughout the bulk of the solvent , left floating around freely in the medium. [1] The internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation , with the use of certain excipients or suspending agents.
An example of a suspension would be sand in water. The suspended particles are visible under a
microscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid , in which the suspended particles are smaller and do not settle.
Colloids and suspensions are different from
solution , in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed.
<h2>Answer:</h2>
The correct answer is option B which is neutron absorbing material.
<h3>Explanation:</h3>
- In nuclear reactors, uranium absorbs a neutron, broke into two nuclei and releasing 3 more neutrons and energy. These neutrons further absorbed by other uranium atoms.
- Control rods are used to control the fission reaction in nuclear reactors by absorbing neutrons.
- Hence the material used in control rods is neutron absorbing material.
Answer:
a) Mg and S = atoms
b) H2 SO3 = molecules
c) HBr =molecule
Explanation:
Step 1: Data given
Atoms = An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. We can find them on the periodic table.
Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
a. Mg S = Magnesium and sulfur both are atoms, we both can find them on the periodic table
b. H2 SO3 = H2 is a molecule that contains 2 hydrogen atoms
SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms
c. HBr = HBr is a molecule that contains 1 hydrogen and 1 bromine atom
