Answer:
it would be the second option. It responds to stimuli to help protect an organism and maintain structure
Answer:
21.28 grams solute can be added if the temperature is increased to 30.0°C.
Explanation:
Solubility of solute at 20°C = 32.2 g/100 grams of water
Solute soluble in 1 gram of water =
Mass of solute in soluble in 56.0 grams of water:
Solubility of solute at 30°C = 70.2g/100 grams of water
Solute soluble in 1 gram of water =
Mass of solute in soluble in 56.0 grams of water:
If the temperature of saturated solution of this solute using 56.0 g of water at 20.0 °C raised to 30.0°C
Mass of solute in soluble in 56.0 grams of water 20.0°C = 18.032 g
Mass of solute in soluble in 56.0 grams of water at 30.0°C = 39.312 g
Mass of of solute added If the temperature of the saturated solution increased to 30.0°C:
39.312 g - 18.032 g = 21.28 g
21.28 grams solute can be added if the temperature is increased to 30.0°C.
Answer:
The reaction involved in a campfire (burning of wood) includes:
Explanation:
We can clearly find here that when wood burns in presence of oxygen, there is a loss of mass in the form of gaseous products. Thus, in this case, the law of conservation of mass does not come true.
I support Lisa’s statement but there is a fact associated with the law of conservation of mass. The law stands true only when there is a definite mass of the reactants and products mentioned.
