Answer:
your answer is given below
Explanation:
Take it stepwise, and you are going to have to look up the various heat values.
You have 36.5grams of ice, presumably at 0C. You will need to add heat to take the ice at 0 C to water at 0 C. (Latent heat of melting) Then you add in a different heat value to take the water at 0 C to water at 82.3 C. (Specific heat of water)
Add the two heat amounts together.
Answer:
17%
Explanation:
Given parameters:
Atomic mass of nickel isotope = 57.9g/mol
Experimental value of atomic mass = 59.6g/mol
Unknown:
Percentage error in the measurement.
Solution:
The percentage error shows how much uncertainty was introduced into a measurement. To calculate this, we simply use the expression below:
Percentage error =
Percentage error = x 100 = 17%
The net cell reaction is: 2Al(s) + 2Br2(l) → 4Br(s) + 2Al2O3(s)
What is a net cell reaction?
A net cell reaction is the overall chemical reaction that occurs during a redox reaction in a cell. It is the sum of all of the individual chemical reactions that take place in the cell and is usually written as an equation with the reactants on the left-hand side and the products on the right-hand side.
What is a chemical reaction?
A chemical reaction is a process in which two or more substances interact to form new substances with different chemical properties. Chemical reactions involve the breaking and forming of chemical bonds, releasing or absorbing energy, and can be either exothermic (releasing energy) or endothermic (absorbing energy).
