Answer:
a ruler or measuring cups are ways of measuring
Explanation:
Depends on where the object is. On earth, moon , or somewhere without any other mass (theoretically). I think you mean how much does weigh on earth. So, the average gravitational acceleration on earth is : 9.83 m/s^2 To find out how much an object weighs, this is the formula : G=m.g where m is mass of the object g is the gravitational acceleration and G is weight. So, G = 10.9,83 = 98,3 N is the answer.
Answer: In order to increase the rate of reaction between hydrochloric acid and sugar increase the concentration of hydrochloric acid to 2 M because greater concentration results in more collision between the reactants.
Explanation:
More is the concentration of reactant molecules more will be the number of collisions between their molecules. As a result, more readily the products will be formed.
Hence, for the given reaction when concentration of HCl is increased then there will be increase in the number of collisions between reactants.
Thus, we can conclude that in order to increase the rate of reaction between hydrochloric acid and sugar increase the concentration of hydrochloric acid to 2 M because greater concentration results in more collision between the reactants.
The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized
Answer:
Statistics
Explanation:
The science of statistics deals with the collection, storage, manipulation, analyzing, visualizing and interpretation of data. Graphs and tables are very good tools in order to achieve statistical problems. Tables can be used to compare a given data set and present them in a very simple relational way. Graphs are useful for data visualization and their trend is vital in making interpretations.
