I WILL GIVE BRAINLIEST PLEASE DO IT RIGHT!!! 1) Using the data below, create two simple line graphs on a separate sheet of paper

that will help you to determine the type of reaction. Your graphs should have the independent variable on the y-axis (temperature) and the dependent variable on the x-axis (time). Because we did not measure the time in the same intervals, you should do two separate graphs rather than a combined one. You must determine the correct spacing for your axis and the scale. Make sure that the graphs are labeled correctly and are titled.
2) How can you tell from your graphs which reaction was endothermic and which one was exothermic?

What is the difference between Mixtures and Compounds? I am trying to study for my Science quiz on Tuesday, and I need to know t
Deffense [45]
A mixture can be separated.  Everything in a mixture keeps it's own properties and are not chemically joined together.  I am not completely sure about the compound.  Although with the cake example, the ingredients have been mixed and kind of "fused" together upon baking. Hope this helps a little. (P.S. trail mix is a good example of a mixture.)

Fan blades would be an analogy for which atomic model?
julia-pushkina [17]
I believe the correct answer from the choices listed above is option A. Fan blades would be an analogy for electron cloud model. Austrian physicist Erwin Schrödinger (1887-1961) developed an “Electron Cloud Model<span>” in 1926. It consisted of a dense nucleus surrounded by a cloud of electrons. Hope this helps.</span>

What’s the electron configuration of an N-3 ion
Alla [95]

Answer:

1s2 2s2 2p6

Explanation:

The nitride ion(N^3-) is formed when nitrogen gains three electrons. Nitrogen possesses seven electrons in its orbitals and ordinarily has the electronic configuration; 1s2 2s2 2p3. However,being in group 15, nitrogen can accept three electrons to form the nitride ion and complete its octet of electrons. When this happens, three electrons are added to the nitrogen atom and the electronic configuration is now the same as that of Neon, its closest noble gas which is 1s2 2s2 2p6. Hence the answer given above.

Elements can accept or donate electrons in order to complete their octet structure in accordance to the octet rule which states that atoms and ions must possess eight electrons in their outermost shell in order to attain chemical stability. The reason for ion formation and chemical reaction is in order for species to attain the octet structure.

Potassium metal and chlorine gas combine in a reaction to produce an ionic compound. What is the correct balanced equation for t
Alisiya [41]

Answer:

2K (s) + Cl₂ (g) ⇒ 2KCl (s)

Explanation:

Potassium and chlorine gas combine to form potassium chloride which is an ionic compound. The reaction is a type of combination reaction in which chlorine is being added to the metal, potassium.

Potassium reacts violently with the chlorine which is yellowish green in color to produce white solid of potassium chloride.

The balanced reaction is shown below as:

2K (s) + Cl₂ (g) ⇒ 2KCl (s)
