What are the products of the double-replacement reaction between potassium bromide and silver nitrate? Name the resulting compou
timofeeve [1]

Explanation:

A double replacement reaction is a reaction in which two different compounds are mixed together and both their cations and anions get exchanged with each other respectively.

When potassium bromide reacts with silver nitrate then it results in the formation of potassium nitrate and silver bromide.

The chemical reaction equation is as follows.

        KBr + AgNO_{3} \rightarrow KNO_{3} + AgBr

A geosynchronous Earth satellite is one that has an orbital period of precisely 1 day. Such orbits are useful for communication
koban [17]

Answer:

r = 4.24x10⁴ km.  

     

Explanation:

To find the radius of such an orbit we need to use Kepler's third law:

\frac{T_{1}^{2}}{T_{2}^{2}} = \frac{r_{1}^{3}}{r_{2}^{3}}

<em>where T₁: is the orbital period of the geosynchronous Earth satellite = 1 d, T₂: is the orbital period of the moon = 0.07481 y, r₁: is the radius of such an orbit and r₂: is the orbital radius of the moon = 3.84x10⁵ km.                           </em>                              

From equation (1), r₁ is:

r_{1} = r_{2} \sqrt[3] {(\frac{T_{1}}{T_{2}})^{2}}                            

r_{1} = 3.84\cdot 10^{5} km \sqrt[3] {(\frac{1 d}{0.07481 y \cdot \frac{365 d}{1 y}})^{2}}      

r_{1} = 4.24 \cdot 10^{4} km      

Therefore, the radius of such an orbit is 4.24x10⁴ km.

I hope it helps you!

Which body is in equilibrium?
sergey [27]
"(1) a satellite moving around Earth in a circular <span>orbit" is the only option from the list that describes an object in equilibrium, since velocity and gravity are working together to keep the orbit constant. </span>

A student states, "The wave model is better than the particle model for electromagnetic radiation because it is easier to unders
Kobotan [32]

The student's claim did not follow the scientific method of discovery, hence, it is an opinion not a scientific claim.

<h3>What is the scientific method?</h3>

The scientific method is a procedure employed by scientific towards understanding the world around them as well giving explanation for phenomena in the natural world.

The scientific method involves:

  • observations
  • asking questions
  • putting forward a hypothesis
  • testing the hypothesis through experiments
  • analyzing results of the experiments and drawing conclusions
  • establishing a theory.

Since the student in question just put forward an opinion without testing it out using the scientific method, the statement is not a scientific claim.
