D
Larger surface area speeds up reactions
Rust is an oxide so more oxygen should speed up rate of rust
Temperature also speeds up reactions
+ The humidity affects it aswell
Answer:
The mass number of an isotope is the sum of neutrons and protons.
Explanation:
In any elemental isotope, the only things that will affect molar mass and mass number is the number of protons and neutrons. Electrons are not counted because we usually assume they are equal to the amount of protons and have no weight.
Protons are what gives the element its atomic number and the neutrons determine the type of isotope it is within the element.
For instance:
There can be a regular Carbon - 12
But there are isotopes like Carbon - 13 and Carbon - 14.
*The number of protons stays the same but the number of neutrons are different
Using the combined gas law, where PV/T = constant, we first solve for PV/T for the initial conditions: (4.50 atm)(36.0 mL)/(10.0 + 273.15 K) = 0.57213.
Remember to use absolute temperature.
For the final conditions: (3.50 atm)(85.0 mL)/T = 297.5/T
Since these must equal, 0.57213 = 297.5/T
T = 519.98 K
Subtracting 273.15 gives 246.83 degC.
Disaccharide forms when two monomers join.
