Answer:
As solute concentration increases, vapor pressure decreases.
Step-by-step explanation:
As solute concentration increases, the number of solute particles at the surface of the solution increases, so the number of <em>solvent </em>particles at the surface <em>decreases</em>.
Since there are fewer solvent particles available to evaporate from the surface, the vapour pressure decreases.
C. and D. are <em>wrong</em>. The vapour pressure depends <em>only</em> on the number of particles. It does not depend on the nature of the particles.
Answer:
See the answer below
Explanation:
Organic molecules in the form of carbohydrates are created during photosynthesis or chemosynthesis and these processes cause carbon to be removed from the atmosphere or other environment into the biosphere - the living organisms of the ecosystem.
During photosynthesis, atmospheric carbon dioxide is fixed as carbohydrates into green plants in a two-stage process that requires sunlight energy and water. The entire process can be summarized as an equation below:
Instead of using water as a reactant, chemosynthetic organisms make use of high energy chemicals such as hydrogen sulfide to fix carbon dioxide in order to generate carbohydrates.
Both processes ensure that carbon dioxide moves from the environment into living organisms.

Answer:
c = 0.528 J/g.°C
Explanation:
Given data:
Mass of titanium = 43.56 g
Heat absorbed = 0.476 KJ = 476 j
Initial temperature = 20.5°C
Final temperature = 41.2°C
Specific heat capacity = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 41.2°C - 20.5°C
ΔT = 20.7 °C
476 J = 43.56 g × c × 20.7 °C
476 J = 901.692 g.°C × c
c = 476 J / 901.692 g.°C
c = 0.528 J/g.°C
Answer:
the same as the products.
Explanation:
Law of conservation of mass states that the mass of the reactant is always the same as the products since they are not lost nor gained.
