Answer:
2. Chemical reactions changes occur when the bonds between atoms in a molecule are created or destroyed.
3. When you reach your its boiling point, the molecules in liquid have enough energy to become a gas.
4. When you have a solid with more than one type of compound, it is called a mixture.
5. A Crystal is a form of solid where the atoms are arranged is a very specific order.
6. If you have different types of molecules dissolved in a liquid, it is called a solution
C2H2, or acetylene, has a molar mass of 26g. That means it has 113/26 = around 4.34 mols. Assuming complete combustion, the balanced equation comes out to this:
C2H2 + 3O2 --> 2H2O + 2CO2
Using the molar ratios, we get that we get 8.68 mols of water for every 4.34 mols, so since the molar mass of water is 18 grams per mol, we multiply 18 * 8.68 = about 156.24 grams.
Answer:
The vacuoles in fungi help the cell to maintain the biochemical condition of its internal cellular environment by moderating the pH of the cell.
Explanation:
Homeostasis is the maintenance of the cellular internal environment, in term of solute optimum concentration, pH, ions moderation, and water regulation. The influx of toxic ions such as amino acids and phosphates grouped into the fungal vacoule usually regulate the amount of dissociable hydrogen ions that is available outside, but within the cells. This sustains the hydrogen ion concentration within the fungal cell to such a degree that is needed for physiological process in the cell.
