Explain the different principles that allow roller coasters to rip and roar around the tracks. In your response, include how ene
Jlenok [28]

Answer:

In the roller coasters the potential energy that is given is the gravitational potential energy, which this energy increases its value as the object moves away from the earth, that is to say, the more height the roller coaster acquires the more gravitational potential energy it will have, and Said train where people usually get on the roller coaster will descend or descend with greater acceleration.

This gravitational potential energy once the mountain begins to descend or descend is converted into kinetic energy

Explanation:

This that we wrote above is considering that the roller coaster does not have curved routes but rectilinear, in the case that it had curved routes, a force would be added in addition to those written that is the centripetal force, it is the same force that appears in the centrifuges or dryers of clothes or the same washing machine. This force, the centripetal force is the force that draws a moving object, in a curvilinear path, towards the center of the curvature.

Complete and balance the equations for the given single displacement reactions. Write the reaction in molecular form. Phases are
Elan Coil [88]

Answer:

Li(s) + H2O(l) -----> LiOH(aq) + H2(g)

Ca(s) + 2H2O(l) ---------------> Ca(OH)2(aq) + H2(g)

Explanation:

Metals react with water to yield the metal hydroxide and hydrogen gas as shown in the answer above.

The reaction equations were balanced, the number of atoms of each element on both side of the reaction equation is exactly the same.

This is the way to write a balanced reaction equation for the species shown in the question.

g If the titration of a 10.0-mL sample of sulfuric acid requires 28.15 mL of 0.100 M sodium hydroxide, what is the molarity of t
Leona [35]

Answer:

M_{acid}=0.141M

Explanation:

Hello,

In this case, the reaction between sulfuric acid and hydroxide is:

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

We can notice a 1:2 molar ratio between the acid and the base respectively, therefore, at the equivalence point we have:

2*n_{acid}=n_{base}

And in terms of volumes and concentrations:

2*M_{acid}V_{acid}=M_{base}V_{base}

So we compute the molarity of sulfuric acid as shown below:

M_{acid}=\frac{M_{base}V_{base}}{2*V_{acid}} =\frac{0.100M*28.15mL}{2*10.0mL}\\ \\M_{acid}=0.141M

Best regards.
