When two or more substances blend but do not chemically combine it is a _____________.
Oksi-84 [34.3K]

Answer:

Mixture.

Explanation:

Hello,

In this case, when blending we are continuously sliding the substances until we obtain small particles that when do not chemically but physically combine we say they are forming a mixture. Nevertheless, when they chemically combine they form a chemical compound due to the formation of bonds between them.

Regards.

An aqueous solution of ammonium sulfate is allowed to react with an aqueous solution of calcium nitrate.
Salsk061 [2.6K]

<u>Answer:</u> The net ionic equation contains Ca^{2+}(aq.) ions

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of ammonium sulfate and calcium nitrate is given as:

(NH_4)_2SO_4(aq.)+Ca(NO_3)_2(aq.)\rightarrow CaSO_4(s)2NH_4NO_3(aq.)

Ionic form of the above equation follows:

2NH_4^{+}(aq.)+SO_4^{2-}(aq.)+Ca^{2+}(aq.)+2NO_3^{-}(aq.)\rightarrow CaSO_4(s)+2NH_4^+(aq.)+2NO_3^-(aq.)

As, ammonia and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

Ca^{2+}(aq.)+SO_4^{2-}(aq.)\rightarrow CaSO_4(s)

Hence, the net ionic equation contains Ca^{2+}(aq.) ions

Which of the following geological features can form at a subduction zone?
saw5 [17]

D

This feature is formed at destructive boundaries where the denser plate (usually the oceanic plate) is subducted underneath the less dense plate (usually the continental plate).

Explanation:

the stress in the boundary between the two plates causes them to warp at the boundary forming a trench. This forced bending and the friction between the two plates (remember tectonic plates are very rugged) causes fissures to develop at the boundary. As the denser plate dives into the mantle, it begins to melt and the molten rock rises through the fissures. The magma erupts at the surface in several fissures forming volcanic mountains ranges along the convergent boundary.
