The amount to administer to the child is 2,469 mL.
To convert to kilograms (kg), the child's weight in pounds (lb) is multiplied by 0.45359237: m(child) = 72.6 · 0.045359237 = 32.93 kg.
To find m(Medrol), the child's mass in kilograms is multiplied by 1.5 mg/kg.
Thus, m(Medrol) = 32.93 kg · 1.5 mg/kg = 49.39 mg.
The concentration of Medrol is d(Medrol) = 20.0 mg/mL.
To find the volume of Medrol needed, use V(Medrol) = m(Medrol) ÷ d(Medrol).
So, V(Medrol) = 49.39 mg ÷ 20 mg/mL = 2,469 mL.
A heavier player collides with a lighter player using greater force.
The lighter player sustains more injuries following the impact.
Explanation:
A heavier player impacts a lighter player with greater intensity, resulting in more pronounced injuries to the lighter player post-collision.
Force is defined as mass multiplied by the acceleration of an object;
Force = mass x acceleration
We observe that as mass and acceleration increase, the force exerted rises accordingly.
Clearly, the heavier player's mass surpasses that of the lighter player, leading to a greater force exerted upon collision.
Moreover, the lighter player is likely to be injured more severely after the clash. The momentum generated by the heavier player during the impact is considerably significant. Once they collide, the lighter player will certainly alter their speed and trajectory.

Answer: 
, 
, NaOH are all ionic compounds.
Explanation:
Ionic compounds form when one atom transfers its valence electrons to another atom, resulting in partial opposite charges on the participating atoms, which creates a strong attractive force between them.
An ionic bond is typically established between a metal and a non-metal.
For instance, , , NaOH are all ionic compounds.
Conversely, a covalent compound arises through the sharing of electrons among the atoms involved, where generally a non-metal bonds with the same or another non-metal.
For example, 
, 
etc are all covalent compounds.
Therefore, we can affirm that , [tex]CH_3CH_2COONa, NaOH are indeed ionic compounds.
The Chemistry Regents is one of the four science Regents exams. The remaining three are Earth Science, Living Environment, and Physics. Passing at least one of these four exams is a requirement for high school graduation.
Answer:
C. connecting an active metal to designate the pipe as the cathode in an electrochemical cell.
Explanation:
Cathodic protection involves a method to manage the accelerated corrosion of a metal surface by designating it as the cathode within an electrochemical cell. This is accomplished by attaching the protected metal to a more sacrificial metal, which acts as the anode.
This method helps to preserve the metal by introducing a highly reactive metal that serves as the anode, supplying free electrons. By adding these free electrons, the active metal gives up its ions, protecting the less reactive steel from corrosion.
