Answer is no
The chemical reaction between iron and oxygen in the presence of moisture or water produces a new substance, which is the rust (iron oxide). In this case, it shows a chemical property.
Answer:
Carbon-12
Explanation:
Because,it is the most abundant.
Answer:
Osmotic pressure is: 2,01 atm
Explanation:
Osmotic pressure is the minimum pressure that you needs to be apply to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. The formula of osmotic pressure is:
π = M×R×T
Where:
M is molar concentration of dissolved species (units of mol/L). <em>0,078M</em>
R is ideal gas constant (0.08206 L atm mol⁻¹ K⁻¹, ).
T is the temperature on the Kelvin scale. 41°C +273,15 = 314,15 K
Replacing you have:
π = 0,078M×0.08206 L atm mol⁻¹ K⁻¹×314,15 K
<em>π = 2,01 atm</em>
