Answer:
70 180 000 kg
Explanation:
We can solve this problem by multiplying the amount of garbage each Canadian throws out each day (2.2 kg) by the number of Canadians:
- 2.2 kg/person * 31 900 000 persons = 70 180 000
Thus according to this problem, all Canadians throw out 70 180 000 kg of garbage each day.
Answer:
Another name of activation energy is "Needed energy" .
Explanation:
Activation energy can be imagined of as the measurement of the potential barrier (seldom described the energy barrier) distributing minima of the potential energy surface concerning the initial and ultimate thermodynamic phase. For a chemical reaction or distribution to advance at a reasonable rate, the specific temperature of the operation should be high satisfactory so that there subsists an apparent number of particles with translational energy equivalent to or higher than the activation energy. The word Activation Energy was founded in 1889 by the Swedish expert Svante Arrhenius.

B is a positive and so is Tourism.
Answer:
Molecular formulas indicate how many atoms there are of each element in a compound, while empirical formulas indicate the reduced proportion of elements in a given compound. The molecular formula can be achieved through the empirical formula if the molecular weight of the compound is known, therefore the empirical formula alone cannot be used to obtain the molecular formula.
Explanation:
An empirical formula expresses the relative relationships of the different atoms in a given compound. For example, H2O is made up of two hydrogen atoms and 1 oxygen atom. In the same way, 1.0 mol of H2O is made up of 2.0 mol of hydrogen and 1.0 mol of oxygen. .
The molecular formula for a compound is always the empirical formula. The molecular formula can be obtained from the empirical formula if the molecular weight of the compound is known.
