Answer:
The specific heat capacity of a metal is 1.31 J/g°C = C
Explanation:
A classical excersise of calorimetry to apply this formula:
Q = m . C . ΔT
177.5 J = 15 g . C (34°C - 25°C)
177.5 J = 15g . 9°C . C
177.5 J /15g . 9°C = C
1.31 J/g°C = C
A particle is a minute fragment or quantity of matter. In the physical sciences, a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume or mass. ... The term is rather general in meaning, and is refined as needed by various scientific fields.
... change its form, such as the phases of matter, or convert into energy.
Answer:
B. the same as the concentration gradient for Na+
Explanation:
The net electrochemical gradient movement of potassium is to move into the cytoplasm of the cell, and the net electrochemical gradient of sodium is to move into the extracellular fluid. There is an overall negative net charge inside the cell than compared to the outside because of this
