Answer:

The correct answer is option 1, that is, resistance to weathering.

Explanation:

After examining the picture of the waterfall, the feature, which is mainly accountable for the presence of the rock ledge is its greater resistance to weathering. Some kinds of rocks are very resistant to weathering. The igneous rocks, mainly the intrusive rocks like granite, weather gradually as it is tough for water to get inside them. The rocks behave distinctly to weathering because of the differences in the structure of mineral and its content.

Which of the following is a property of an ionic compound?
svet-max [94.6K]
Ionic compound is a chemical compound composed of ionsheld together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic species such as the ammonium (NH+
4) and carbonate (CO2−
3) ions in ammonium carbonate. Individual ions within an ionic compound usually have multiple nearest neighbours, so are not considered to be part of molecules, but instead part of a continuous three-dimensional network, usually in a crystalline structure.

Ionic compounds containing hydrogen ions (H+) are classified as acids, and those containing basic ions hydroxide (OH−) or oxide (O2−) are classified as bases. Ionic compounds without these ions are also known as salts and can be formed by acid–base reactions. Ionic compounds can also be produced from their constituent ions by evaporation of their solvent, precipitation, freezing, a solid-state reaction, or the electron transfer reaction of reactivemetals with reactive non-metals, such as halogen gases.

Ionic compounds typically have high melting and boiling points, and are hardand brittle. As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized.

This is answer

high melting point
malleable

Hydrogen is manufactured on an industrial scale by this sequence of reactions:
hichkok12 [17]

Answer:

K=K_1*K_2\\\\K=\frac{[H_2]^3[CO_2][H_2]}{[CH_4][H_2O][H_2O]}

Explanation:

Hello there!

In this case, for the given chemical reaction, it turns out firstly necessary to write the equilibrium expression for both reactions 1 and 2:

K_1=\frac{[CO][H_2]^3}{[CH_4][H_2O]} \\\\K_2=\frac{[CO_2][H_2]}{[CO][H_2O]}

Now, when we combine them to get the overall expression, we infer these two are multiplied to get:

K=K_1*K_2\\\\K=\frac{[CO][H_2]^3}{[CH_4][H_2O]} *\frac{[CO_2][H_2]}{[CO][H_2O]}\\\\K=\frac{[H_2]^3[CO_2][H_2]}{[CH_4][H_2O][H_2O]}

Regards!
