Hello!
density = 2.67 g/cm³
volume = 30.5 mL
Thus:
Mass = density * volume
Mass = 2.67 * 30.5
Mass = 81.435 g
Answer:
In blood: Dispersed phase: blood cells; Dispersed medium: liquid plasma
In fruit jelly: Dispersed phase: fruit juice; Dispersed medium: pectin
Explanation:
The dispersed phase refers to the phase where colloidal particles are dispersed within another phase, known as the dispersion medium.
In blood, the tiny cells act as colloidal particles, forming the dispersed phase within the liquid medium identified as plasma.
Conversely, in fruit jelly, the fruit juice constitutes the dispersed phase while the solid pectin serves as the dispersed medium.
Water transitions to ice when temperatures drop too low, while it turns into gas when temperatures rise too high.
Conversely, ice transforms back into water when heated, remaining unchanged if temperatures are too low.
Furthermore, gas transitions to water when cooled and can freeze into ice if cooled further, continuing this cycle.
I hope this clarifies things.
The reaction will yield 2 mol of H₂O. The balanced chemical equation for this process is: c3h8 (g) + 5o2 (g) → 3co2 (g) + 4h2o (g). Since 5 moles of O₂ create 4 moles of H₂O, 2.5 mol of O₂ will produce: 2.5 x 4/5 = 2 mol of H₂O.
A molecule's polarity is influenced not only by specific atoms but also by its symmetry. For instance, alkanes are typically non-polar due to the absence of a net dipole moment. A dipole moment occurs because of differences in electronegativity between carbon and other elements, commonly oxygen, halogens, and nitrogen, which, due to their high electronegativity, create a net dipole moment and thus polarity.
exhibits symmetry and is therefore non-polar.
, being asymmetrical, is polar due to its bent structure influenced by the oxygen's lone pairs.
