As powder because the smaller the particle size the faster the reaction
say for example, instead of a stick of chalk you have powder. Each bit of powder is a particle of chalk, and if you dip your finger into the powder, you can still write on the blackboard with it.

Specific active site is denatured
yes,it is a suspension because it is a heterogeneous mixture which is given in the question so it can not be a true solution. in the case of suspension the chalk powder in water is insoluble and the particle size is more than 2000 but in colloidal solution both in dispersed phase and dispersed medium the particles are soluble. so, it is a suspension.generally chalk powder in water is insoluble
It varies depending on the particle size of the powder.
As powder because the smaller the particle size the faster the reaction
I think the different its coming from particle size of powder, compacted powder is more finer than micronized and use for tablet and capsule dosage, micronized have a large particle size and use for dry suspension.
Masterbatch-Manufacturer direct sales-Doleungchoi Specifications of masterbatches Masterbatch is a granular solid composed of particle size 0.1~3mm. 0.1mm (100μm) is a powder composed of particles; 1~10μm is a fine powder; 0.1~1μm is an ultra-fine powder; particles of 》3mm are broken solid blocks. The smaller the particle size, the more dense the mixture obtained. However, the smaller the particle size of the same solid, the easier the particles are also adsorbed to each other agglomerate, this agglomeration, in mixing with another solid particles is not easy to open, in the plastic melt is also difficult to disperse. Particle size distribution: masterbatch particle size distribution wide powder filling properties than the narrow particle size distribution more dense. Because the small particle size can enter the gap between the large particles to go, but the two kinds of particle size difference between the powder mixed, it is difficult to mix uniformly.

Suspension is a hetrogenous mixture where particle are "suspended" in medium and can be seprated by easy process like sedimentation etc eg dust particle in air, chalk powder in water Solution is a homogenous mixture where you wont find particle in medium. eg suger in water,
Huh?
yes
Mesh denotes particle size or granulation of powder. When guar gum powder is prepared, it is granulated through mesh screens during the sieving process. +40 mesh means powder will pass through a sieve of 40 mesh. -100 mesh means powder will not pass through a sieve of 100 mesh. +40/-100 mesh guar gum powder means 90% of powder will pass through 40mesh but not through 100 mesh. Hence particle size lies between 40mesh and 100mesh. Read wikipedia article on mesh.
