Answer:
The correct answer is B.)Potassium iodide in water
Explanation:
An electrolyte is a compound that can dissociate into ions when is dissolved in a solvent. The resulting solution has the ability to conduct the electricity because there are electrical charges (ions) in the solvent. The most common electrolytes are soluble salts.
From the options, methanol (A), pentane (C) and sucrose (D) are organic compounds that cannot be dissociated into ions in the solvents in which are soluble. The only correct option is (B), because potassium iodide (KI) is a soluble salt that disociates into ions (K⁺ and I⁻) when is dissolved in water:
KI → K⁺ + I⁻
This is a true statement if it is density you are looking for... Density problem.....
Density is the ratio of the mass of an object to its volume.
D = m / V
D = 104g / 14.3 cm³ = 7.27 g/cm³ .............. to three significant digits
The conventions for the units of density is that grams per cubic centimeter (g/cm³) are usually used for solids, but will work for anything. Grams per milliliter (g/mL) are usually used for liquids and grams per liter (g/L) are for gases. Therefore, by convention, the units for tin (a solid) should be in grams per cubic centimeter.
Since 1 mL is equivalent to 1 cm³, then the density could be expressed as 7.27 g/mL.
The accepted value for the density of tin is 7.31 g/cm³
Plants are chlorophyll-containing photosynthetic organisms. Thus, they convert solar or radiant energy into chemical energy under the process termed as photosynthesis.
<u>Explanation:</u>
- Plants are chlorophyll-containing photosynthetic living beings. Consequently, they convert radiant energy into chemical energy under the procedure named photosynthesis.
- Except for remote ocean hydro-thermal environment, the sun is the only source for all biological systems on earth. Plants catch just 2-10 percent of the solar radiation and transmit it as chemical energy. All creatures are reliant for their nourishment on producers (plants), either directly or indirectly. So there is a stream of energy from the sun (radiant energy) to producers and then to consumers (chemical energy).
