Answer:

Hello There!

Explanation: Your Answer will be, D) conduct electricity in water.

Both acids and bases conducts electricity and water.

When acid dissolves in water, they are good electrolytes.

When bases dissolves in water they are good electrolytes.

Electrolytes are liquid or molten substances that are able to conduct electricity.

they conduct electricity by the use of their ions in solution.

Since acid and bases ionize in solution, they will conduct electricity.

An acid is a substance that produces excess hydroxonium ion in solution.

A base produces excess hydroxyl ions in solution. Hope This Helps!

Answer: Economic geography takes a variety of approaches to many different topics, including the location of industries, economies of agglomeration (also known as "linkages"), transportation, international trade, development, real estate, gentrification, ethnic economies, gendered economies, core-periphery theory, the economics of urban form, the relationship between the environment and the economy (tying into a long history of geographers studying culture-environment interaction), and globalization.

Answer:

 Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+ number 2  A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. number 3 giant metallic, giant ionic, simple molecular, and macromolecular ... it has positive ions surrounded by a sea of delocalised electrons ... m/z value than Cl⁻. this means that F⁻ is more attracted to the Ca²⁺ ion more strongly ... What bond angle does beryllium chloride, BeCl₂ have? ... Give two examples of linear molecules.

The formula of thallium carbonate is Tl₂CO₃. The intermolecular force of attraction between electrons and protons proceed to the combination of two atoms. The net dipole moment in BeCl₂ is zero since they cancel each other due to linear geometry.

Thallium carbonate is an inorganic compound formed by the ionic bonding between thallium and carbonate group. The charge of thallium Tl is +1 and that of carbonate group is -2. Hence the chemical formula of the compound is Tl₂CO₃.

Unstable atoms with deficient number of electrons combines with other atoms to form compounds. The force that act between the two atoms is called intermolecular force of attraction.

The electrons of an atom is attracted by the positive charge of nucleus of other atom results in the chemical bonding.

Barium chloride is an ionic compound with linear geometry. The chlorine atom is highly electronegative and will attract the shared pair of electrons into it.

The two chlorines are arranges linearly on either side of Be thus, the dipole will be opposite in direction towards each chlorine atoms. Thus it cancel and net dipole moment become zero. That's why the compound is nonpolar.

Answer:

Physical properties: how soft a blanket it, how hard bread is, what color leaves are, what bleach smells like.

Chemical change: burning wood, rotting food, digestion, rusting of a nail.

Physical change: mixing salt and sugar, tearing a piece of paper, melting ice, chopping wood.

Explanation:

Physical properties are properties that are measurable.

Chemical change is when substances combine (fire and wood make burning wood) to make another substance. They aren't reversible. If you were to melt ice, you could refreeze it, you can't unburn wood.

Physical change is something that alters the form of the substance but not the chemical composition.

Hope this helps!
