A tank in the shape of a rectangular prism measures 10 dm by 4 dm by 6 dm. the tank is completely filled with 8908.8 l of liquid
nevsk [136]
1) The question contains an unknown unit


The number 8908.8 has to be in units of mass: for example, kg or grams.


Here you indicated L.


I am going to work assuming that L is a mass unit. So you can see the way to solve the problem, but you have to verifiy the real unit of the statement and substitute with it.



With that in mind you can find the density of the liquid from:


density  = mass / volume


2) Calculate the volume.


The volume of the liquid is the volume of the vessel, because it is filled.


The volume of the vessel is calculated from the formula of volume for a rectantular prism.


Volume of a rectangular prism = area of the base * height = side * side * height


=> Volume = 10 dm * 4 dm * 6 dm = 240 dm^3 = 240 liter


3) Calculate the density:


density = mass /volume = 8,908.8 L / 240 liter   =  37.12 L / dm^3



Answer: 37.12 L / dm^3

Which list represents the classification of the elements nitrogen, neon, magnesium, and silicon, respectively?
serious [3.7K]
The question is incomplete. Complete question is:
Which list represents the classification of the elements nitrogen, neon, magnesium, and silicon, respectively?
(1) metal, metalloid, nonmetal, noble gas
(2) nonmetal, noble gas, metal, metalloid
(3) nonmetal, metalloid, noble gas, metal
(4) noble gas, metal, metalloid, nonmetal
.................................................................................................................

Answer: The correct answer is option 2) nonmetal, noble gas, metal, metalloid

Reason: 
1) Non-metal are bad conductors of electricity. Also non-metal are electronegative in nature. Hence, among the provided elements, nitrogen satisfied the criteria. Hence, it is a non-metal.

2) Noble gas are the elements which have completely filled outermost shell. Hence, among the provided elements, Neon satisfied the criteria.

3) Metal are good conductors of electricity. Also metal are electropositive in nature. Hence, among the provided elements, magnesium satisfied the criteria. Hence, it is a metal.

4) Metalloid have conductivity better than non-metals but poor than conductors. Hence, among the provided elements, Silicon satisfied the criteria. Hence, it is a metalloid.

2. The reaction of zinc with nitric acid was carried out in a calorimeter. This reaction caused the temperature
snow_lady [41]

We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.

Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J

Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).

Place the following compounds in order of increasing vapor pressure. rubbing alcohol
adelina 88 [10]

Vapor pressure is the pressure which is exerted by the vapors of a liquid in equilibrium with the liquid. Vapor pressure depends on the boiling point; lower the boiling point higher will be the vapor pressure.

Based on the given compounds:

rubbing alcohol is polar and has the strongest intermolecular force of attraction followed by relatively polar ether and finally the non-polar propane.

The increasing order of boiling point will be:

propane < diethyl ether < rubbing alcohol

Thus, the increasing order of vapor pressure will be:

rubbing alcohol < diethyl ether < propane

Ans : F

What element glows in sign's when excited
ser-zykov [4K]

Answer:

The element that glows in signs is xenon.

Explanation:

Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth's atmosphere in trace amounts. Xenon is used in flash lamps, arc lamps, and as a general anesthetic. Xenon emits a blue or lavenderish glow when excited by electrical discharge, it emits a band of emission lines that span the visual spectrum, but the most intense lines occur in the region of blue light, producing the coloration.
