Answer:
It is not a gas because its particles do not have large spaces between them.
Explanation:
Solids and liquids have a lot of particles with few spaces between them. Also, gas particles move rapidly in each direction.
Answer: 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal
Explanation:
To calculate the moles :
The balanced chemical equuation is:
According to stoichiometry :
4 moles of produce == 2 moles of
Thus 0.556 moles of will produce= of
Mass of
Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.
Heterotrophic cells must ingest biomass to obtain their energy and nutrition. Heterotrophic microorganisms mostly feed upon dead plants and animals, and are known as decomposers. ... Some animals also specialize on feeding on dead organic matter, and are known as scavengers or detritivores. Hope this was helpful.
Answer:Answer: (B) Archaebacteria
Explanation:
Explanation: Archaebacteria, like all prokaryotes, have no membrane bound organelles. This means that the archaebacteria are without nuclei, mitochondria, endoplasmic reticula, lysosomes, Golgi complexes, or chloroplasts. Because these organisms have no nucleus, the genetic material floats freely in the cytoplasm
Answer: 1 . Unsaturated Solution
2. Saturated Solution
Explanation:
1 ..tedsaturauntionsolu----------- Unsaturated Solution
2. ratedsatulutisoon--------------Saturated Solution
An Unsaturated solution is defined as a solution which contains an amount of solute that dissolves completely since the amount of solute is still less than the maximum amount that can readily dissolve in such solution and an additional amount of solute if added continues to dissove in the solution. Here the solution is still less than the equilibrium point.
example include. Addition of salt or sugar in water and it dissoves completely.
A saturated solution is defined as A solution which contains a maximum amount of solute that an additional solute will no longer be capable of being dissolved further since its equilibrium point has been reached.
Example- The addition of sugar to water till it no longer dissolves
Carbonated water is a saturated solution saturated with carbon as can be seen in the air bubbles it gives offf in form of carbon.
