A letter stating three things that need urgent fixing in your school<br><br><br><br>​
ioda

Answer and Explanation:

  • <em>Computers ( The computers are very old and very slow, and we have to notice that almost everyone are using computers at the same time at the school, which makes it even harder for it to load up assignments. )</em>
  • <em>The Rick Rolling ( Everyone keeps sending links to teachers and students saying that it is part of some assignment but then you have to listen to Rick Astley, they should really block these links. )</em>
  • <em>The lockers ( The lockers are also very old and they are breaking down and rusting a lot from the moisture in the hallways. One of the lockers even broke down today!!! I hope they can fix this so no one else gets hit with a locker door. )</em>

<em>Hope this helps! ;)</em>

Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation.
Mariana [72]
<span>Oxidation is the loss of electrons and corresponds to an increase in oxidation state. The reduction is the gain of electrons and corresponds to a decrease in oxidation state. Balancing redox reactions can be more complicated than balancing other types of reactions because both the mass and charge must be balanced. Redox reactions occurring in aqueous solutions can be balanced by using a special procedure called the half-reaction method of balancing. In this procedure, the overall equation is broken down into two half-reactions: one for oxidation and the other for reduction. The half-reactions are balanced individually and then added together so that the number of electrons generated in the oxidation half-reaction is the same as the number of electrons consumed in the reduction half-reaction.</span>

Why is ammonia (NH₃) classified as a polar molecule?
aleksandr82 [10.1K]

Answer:

Ammonia contains an asymmetrical distribution of electric charge.

Explanation:

Hello there!

In this case, accordingly to the electronegativity difference we can calculate for the N-H bond, and based off our periodic table, which shows an electronegativity of 3.0 and 2.1 for N and H respectively, we obtain:

DE=3.0-2.1=0.9

Which is within the range of polar molecule even the both of them are nonmetals. Thus, choices a and b are firstly discarded; nonetheless, even when they are both nonmetals, two of these elements usually have a nonpolar bond, which means that option C is discarded, and therefore, our answer is ammonia contains an asymmetrical distribution of electric charge.

Regards!

A scientist places a large beaker containing 325 g of 50degree Celsius water into a microwave. He has to run the microwave for 3
Bingel [31]

The amount of energy absorbed by the 325g of water is 57,057J. Details about calorimetry can be found below.

<h3>How to calculate energy?</h3>

The energy absorbed by a mass of substance can be calculated using the following formula;

Q = mc∆T

Where;

  • Q = quantity of heat absorbed
  • m = mass of substance
  • c = specific heat capacity
  • ∆T = change in temperature

Q = 325g × 4.18 × (92 - 50)

Q = 57,057J

Therefore, the amount of energy absorbed by the 325g of water is 57,057J.
