Answer:

Increase the particle size of a reactant

Explanation:

Let me rewrite this question. I am assuming that it should be as follows,

If you _____ the particle size of a reactant then the reaction rate will increase because of the reactant's surface area is exposed allowing more particles to make contact with each other.

And, here we are being asked to fill this dash line _____

It could only be that the particle size increases or decreases. Increasing the size of the reactant will increase the chance of collisions if the container with which the reactants are kept are constant. This would increase the reaction rate - thus _____ = increases.

What does it mean to truly love someone?

Minchanka [31]

Truly loving someone means caring for them in the ways that they need to be cared for, with no strings attached. (That's why they call it unconditional love.)

A mixture that separates into different layers when you stop stirring it is Select one: a. a solution. b. a suspension. c. a col

leva [86]

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.

Use the periodic table to identify each of the following bonds as polar or nonpolar.

Molodets [167]

Answer:

Polar

Step-by-step explanation:

Electronegativity increases from <em>left to right</em> in the Periodic Table.

Cl is further right than C (both tinted pink) in the portion of the Periodic Table below.

Cl is <em>more electronegative</em> than C, so the Cl has a partial negative charge and the C has a partial positive charge.

The C-Cl bond is polar.

How do protons electrons and neutrons differ in charge and location in the atom?

dlinn [17]

Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.
