If the same amount of solid sodium (Na) is used in each reaction, which shape will increase the reaction rate the most?

Luba_88 [7]4 years ago
5 0

Answer: (B.) The reaction rate is highest when sodium powder is used.

Explanation:

Five factors that affect the rate of reactions are : Temperature, concentration, nature of catalyst, chemical nature of reactants and  nature of subdivision of particles (heavier size versus smaller or powdered particles).

Nature of subdivision of particles :

Since reactions occur at the boundary between two phases therefore tyhe rate of reaction depends on surface contact available between them. A powdered particle has generally more surface area than the particle in solid form.

What is the mass percent of each element in water
Vladimir79 [104]

Mass Percent of Hydrogen. To find the mass percent of hydrogen in water, take the molar mass of hydrogen in the water molecule, divide by the total molar mass of water, and multiply by 100. Dividing 2.016 by 18.016 gives you 0.1119. Multiply 0.1119 by 100 to get the answer: 11.19 percent

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.
