Explanation:

Answer:Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.

Explanation:

1. Determination of the energy of the ball.

Mass (m) = 5 Kg

Velocity (v) = 10 m/s

Energy (E) =?

E = ½mv²

E = ½ × 5 × 10²

E = 2.5 × 100

E = 250 J

2. Determination of the energy of the rock.

Mass (m) = 250 Kg

Height (h) = 200 m

Acceleration due to gravity (g) = 10 m/s²

Energy (E) =?

E = mgh

E = 250 × 10 × 200

E = 500000 J

3. Determination of the energy of the car.

Mass (m) = 1300 Kg

Velocity (v) = 15 m/s

Energy (E) =?

E = ½mv²

E = ½ × 1300 × 15²

E = 650 × 225

E = 146250 J

4. Determination of the energy of the bullet.

Mass (m) = 0.005 Kg

Velocity (v) = 400 m/s

Energy (E) =?

E = ½mv²

E = ½ × 0.005 × 400²

Explanation:

Answer:

The right solution is "0.7107 J/g°C".

Explanation:

The given values are:

Mass,

m = 4.11 g

Temperature,

ΔT = 3.8°C

Heat,

Q = 11.1 J

The specific heat of silicon will be:

⇒  [tex]C=\frac{Q}{m \Delta T}[/tex]

On substituting the values, we get

⇒      [tex]=\frac{11.1}{4.11\times 3.8}[/tex]

⇒      [tex]=\frac{11.1}{15.618}[/tex]

⇒      [tex]=0.7107 \ J/g^{\circ}C[/tex]

Explanation:

The most important thing to bear in mind when writing chemical reaction equation is that the equation must be balanced. A balanced chemical reaction equation is one in which the number of atoms of each element on the left and right hand sides of the reaction equation is exactly the same.

Equation of magnesium reaction with oxygen

2Mg(s) + O2(g) ------> 2MgO(s)

Equation of magnesium reaction with nitrogen

3Mg(s) + N2(g) ------> Mg3N2(s)

Answer:

neutron

Explanation:

Hopefully this will help you!!!!

Answer:

C

Explanation:

Assuming you had a few typos in the equations, I would say C

I am going to assume the reaction

_C2H6 + _O2 → _CO2 + _H2O

Right now, there is enough hydrogen to make 3 water molecules, but since oxygen comes in groups of 2, it wouldn't work.

Therefore, we need 2 ethane molecules.

2C2H6 + _O2 → _CO2 + _H2O

Then balance the right side with the carbons and hydrogens

2C2H6 + _O2 → 4CO2 + 6H2O

So we need 4 O2's in carbon dioxide and 3 O2's in water (Since water uses 1 oxygen molecule per 2 hydrogens). Hence we will need 7 oxygens

2C2H6 + 7O2 → 4CO2 + 6H2O

And assuming errors in the typing, C should be the answer (if this matches)

Answer:

automatic transmission

Explanation:

An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in motor vehicles that does not require any driver input to change gears under normal driving conditions.

Answer:

5. Amplitude.

6. 344.8 meters/second

Explanation:

5. The energy is proportional to the amplitude is all I remember. Sorry :/ Been a long time since I took these classes.

6. Traveling to the wall & back is 200m

100 + 100 = 200m total traveled

The time is 0.58s so, we can use the speed formula to solve [ s = d/t ] where s = speed, d = distance, and t = time.

s = 200/0.58

s = 344.82758

I don’t know if they’ll have you round, but I would say the speed of the sound is 344.8 m/s.

Answer:

1.3 atm

Explanation:

Apply the ideal gas law: PV = nRT

Since we need to find the pressure, solve for pressure:

P = nRT / V

Plug in our given values of n = 4.6 moles, R = 0.08206 (ideal gas law constant using atm), T = 325 K, and V = 96.8 L:

P = 4.6(0.08206)(325) / 96.8 = 1.267 atm -> 1.3 atm (two significant figures)

The amount of energy required to break the ionic bonds in CaF2.

Answer:

Insects belong to the class Insecta, and arachnids to the class Arachnida; both classes fall under the Arthropoda phylum, along with crustaceans (crabs, lobster and shrimp). All arthropods have an exoskeleton and jointed legs. They have segmented bodies and appendages, which are divided into different segments. Arachnids belong to an even larger group of animals called “arthropods” which also include insects and crustaceans (lobster, crabs, shrimp, and barnacles).

Answer:

evapouration is a type of vaporization that occur on the surface of liquid as it change into the gas phase.

hope it helps.

Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun.

HCI + NaOH --> NaCl + H2O

Neutralization reaction is the reaction between acid and base which results in formation of salt and water. Here salt is NaCl (common salt) in above reaction.

SO, (A) H20 + NaCl is your answer.

Answer:

There is too much here for me to attempt in one sitting, but I will get you started and give suggestions that may help you proceed on your own.

a)  As far as I can tell, you didn't provide the reduction potentials in the table below.  So, I looked them up and find them to be

Cu2+ +2e- ==> Cu(s)  Eº = +0.34 V

Zn2+ + 2e- ==> Zn(s)  Eº = -0.76 V

Net ionic equation:  Cu2+(aq) + Zn(s) ==> Cu(s) + Zn2+(aq)

b)  Eºcell = 0.34 V + 0.76 V = 1.10 V

c)  ∆Gº = -nFEº  where n = number of electrons transferred (2) and F = 96,485 C/mol e- and Eº = 1.1 V

d)  Again, there is no diagram

e)  same

f)  Use the Nernst equation  Ecell = Eºcell - 2.303RT/nF log Q  where R = 8.314; T = Kelvin; F = Faraday const. and Q = reaction quotient, i.e. products/reactants

g)  the cell voltage is an intensive property.  That should help you answer this part of the question

Answer:

2800 g de ácido nítrico

Explanation:

La ecuación por la oxidación de amoniaco es:

4NH₃  +  7O₂  →  4H₂O  +  2HNO₂  +  2HNO₃

Si pensamos que el oxígeno es el reactivo limitante, trabajamos con el amoniaco. Convertimos su masa a moles:

1.36 kg = 1360 g

1360 g . 1mol  /17g = 80 moles

Si 4 moles de amoniaco pueden producir 2 moles de acido nítrico

80 moles producirán, (80 . 2)/4 = 40 moles.

Convertimos los moles a gramos:

40 mol . 63g /mol = 2520 g

Si le aplicamos la pureza

2520 g . 100/90 = 2800 g
