Answer:

Observing what the substance looks (color, size, texture) or smells like (odor). Objects can be made up of the same substance, but they differ in the properties of size, mass, and volume.

Explanation:

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.

Answer:

K^{+} and NO_{3}^{-}

Explanation:

The equation for the reaction is AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq)

With all the ions, it is

Ag^{+}(aq) + NO_{3} ^{-}(aq) + K^{+}(aq) + Cl^{-}(aq)  ==> AgCl(s) +

K^{+} and NO_{3} ^{-} do not change, so they are the spectator ions and are removed

The ionic equation is:

Ag^{+}(aq) + Cl^{-}(aq) ==> AgCl(s)

Tanzania [10]

Answer:

A.  Herbivores have longer digestive systems than carnivores have.

Explanation:

We can conclude that the herbivores have longer digestive systems compared to carnivores.

Carnivores feeds on other animals whereas herbivores eats plants.

  • Most herbivores have a four stomach compartment system that helps them process and digest their food.
  • This is because they have to process cellulose in plants which needs to be properly broken down.
  • Flesh eating carnivores do not require this arrangement.
  • The four stomach compartment of most herbivores includes Rumen, Reticulum, omasum and abomasum.
  • They also chew the cud whereby they regurgitate food materials.

insens350 [35]
Arsenic, I believe. Metalloids fall in between metals and nonmetals (usually on the bold line separating the two on the periodic table). And since the metalloid in question has four electron shells and five valence electrons in the outermost shell, you can see that this element is arsenic
