Identify the solute and solvent in a solution made of 15g of oxygen and 5g<br> of helium
Marrrta [24]

Taking into account the definition of solvent and solute, helium is the solute and oxygen is the solvent.

<h3>Definition of solute and solvent</h3>

The solution is a homogeneous mixture of two or more components that have the same chemical and physical properties in a single phase. A solution is made up of two main components: the solute and the solvent.

That is, the solute and the solvent are the components of a chemical solution, that is, of a homogeneous mixture that occurs when one or more substances are dissolved in another substance.

The solute is the substance that dissolves in a solution. In solution, the solute is usually found in a lower proportion than the solvent.

Solvent is the substance in which a solute dissolves, resulting in a chemical solution. Generally, the solvent is the component that is found in the highest proportion in the solution. It will always be the solvent who will determine the state of the matter that will have the solution.

<h3>Solute ans solvent in this case</h3>

In this case,  you consider that the solute is the component in less quantity and the solvent is the major component.

You know that a solution made of 15 g of oxygen and 5 g of helium. Then, helium is the solute and oxygen is the solvent.

A basketball player jumps straight upward. After 0,625 s, she is 0.441 m above the ground. What is her initial velocity?????????
Lunna [17]

Answer:

v₀ = 3.77 [m/s]

Explanation:

This problem can be solved in a simple way by means of the following equation of kinematics.

y=y_{o}+v_{o}*t+\frac{1}{2}*g*t^{2}

where:

y - yo = 0.441 [m]

Vo = initial velocity [m/s]

g = gravity acceleration = 9.81 [m/s²]

t = time = 0.625 [s]

0.441 = v_{o}*(0.625)-\frac{1}{2} *9.81*(0.625)^{2} \\2.357 = v_{o}*0.625\\v_{o}=3.77[m/s]

Note: The sign of the acceleration is negative since the movement of the basketball player is against of the gravity acceleration.
