Answer 1
Answer: KOH - Potassium hydroxide (The compound for potassium is K, hence the first part, and OH is for hydroxide so when you put them together it makes potassium hydroxide.. pretty self explanatory) 
Ca(NO3)2 - Calcium nitrate (The symbol for calcium is Ca, next is NO which is nitrate and the 3 means that there are 3 Nitrate compounds..I am not 100% sure what the 2 means at the end, but I am guessing it means that there are 2 calcium nitrate compounds in all.)
MgCO3 - Magnesium carbonate
Na3PO4 -Trisodium phosphate
LiNO3 - Lithium Nitrate
Mg(C2H3O2)2 - Magnesium acetate
Answer 2
Answer:

Alright, so to do this, you need to know the name of the elements and compounds, since all of these are ionic compounds which have different naming rules than covalent compounds, all you need is a periodic table and an ion chart. I'll do the first column.

A. Calcium Nitrate

B. Potassium Hydroxide

C. Magnesium Carbonate.

I also am including a picture of an ion chart that include almost all of the ions to help you with the rest of them.

Waves move fastest in low-temperature gases. low-temperature solids. high-temperature gases. high-temperature solids.

Answers

Answer: Option (d) is the correct answer.

Explanation:

At high temperature, there will be more collision between the molecules as a result more energy will generate. Thus, a wave can move quickly.

In case of solids, the particles are held more closely with each other. Therefore, when temperature is high then solid particles being closer can pass on the energy more quickly as compared to gases.

Thus, we can conclude that waves move fastest in high-temperature solids.

Final answer:

In Physics, waves move fastest in high-temperature solids due to the close proximity of particles which facilitates faster wave transmission and the increased kinetic energy at high temperatures.

Explanation:

In the study of Physics, the speed of sound waves varies depending on the properties of the medium through which they are traveling. Solids have tightly packed particles which facilitate faster wave transmission. Conversely, gases have loosely packed particles which slow down wave travel. Temperature, while affecting speed at some level, doesn't have as significant an influence as the state of matter itself.

Therefore, among the options you provided: low-temperature gases, low-temperature solids, high-temperature gases, and high-temperature solids, waves move fastest in high-temperature solids.

This is due to the increased kinetic energy of the particles in a high-temperature solid as compared to a low-temperature solid; and the closer proximity of particles in a solid as compared to a gas.

Which of these formulas contains the most polar bond?
(1) H–Br (3) H–F(2) H–Cl (4) H–I

Answers

The answer is H—F. Fluorine is the most electronegative of the four halogens (and, in fact, of all the elements), so it does the best job of gathering the shared electrons to itself. Therefore, the bond with F is the most polar

A sample of aluminum metal absorbs 8.32 J of heat, upon which the temperature of the sample increases from 23.2 degrees C to 30.5 degrees C. Since the specific heat capacity of aluminum is 0.90 J/g-K, the mass of the sample is what in grams?

Answers

Given:

8.32 J of heat

from 23.2 degrees C to 30.5 degrees C

heat capacity of aluminum is 0.90 J/g-K

 

Required:

m in grams

 

Solution:

H = mCpT

(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K

m = 1.27g
