Answer:

The freshwater sources that are generally in continuous motion and follow a defined path are called streams and rivers.

If I were to improve the lab then I will make the following changes:

  • The experiment aimed to observe and model the effects of rivers on erosion. So, I can make a virtual model of the river and can compare the velocity, gradients and volume of rivers.
  • Comparison between the low and high factors listed can help in computing the effect of the powerful river on erosion.
  • The high velocity. gradient and volume of the river will cause more erosion as it exerts more force.
  • The low volume, gradient and velocity river will affect in a less manner on erosion.

Explanation:

thats all i know ( correct me if im wrong please)

2Mg + O2à MgO For this unbalanced chemical equation, what is the coefficient for oxygen when the equation is balanced? A. 1 B. 2
Vikki [24]

Answer:

The answer to your question is the letter A. 1

Explanation:

Unbalanced chemical reaction

                      Mg  +  O₂  ⇒  MgO

               Reactants    Elements    Products

                       1            Magnesium       1

                       2           Oxygen              1

Balanced chemical reaction

                      2Mg  +  O₂  ⇒  2MgO

              Reactants    Elements    Products

                       2           Magnesium       2

                       2           Oxygen             2

Conclusion

The coefficients of the balanced equation are 2, 1, 2
