1.Start with the number of grams of each element, given in the problem.
2.Convert the mass of each element to moles using the molar mass from the periodic table.
3.Divide each mole value by the smallest number of moles calculated.
4.Round to the nearest whole number. This is the mole ratio of the elements and is.
Answer:
A is your answer i believe
Explanation:
The number of moles and the mass (in kg) of copper(II) carbonate needed to decompose in order to produce 1.500 kg of copper(II) oxide, where CO2 is the other product.
Answer:
D. The others are based on weather not climate.
Explanation:
The answer is -33.6 degree Celsius... or approximately-34 degree Celsius. Firstly, you will change the L to mL so 2.10L to mL is 2100ML.. so if 750ML=-12 degree Celsius then 2100ML is what?? So.. if more less divide.. so 2100ML/750ML *-12 =-33.6 degree Celsius.. approximately -34 degree Celsius. I hope it helped??
