Explanation:

Answer:

The same number of molecules, 6.0 × 10²³ molecules.

Explanation:

The amount of any given gas that can be stored in a container depends on the temperature, pressure and volume of the container. It does not depend on the nature (or identity) of the gas.

So if a 10-liter flask contains 6.0 × 10²³ molecules of hydrogen gas, it will contain the same amount of molecules of any other gas when temperature and pressure remain constant.

Answer:

d. 671.6 nm

Explanation:

It is possible to solve the wavelength of a radiation from its frequency -or vice versa- using:

λ = c / f

Where λ is wavelength,

c is speed of light, a constant (2.998x10⁸m/s)

And f is frequency: 4.464x10¹⁴s⁻¹

Replacing:

λ = 2.998x10⁸m/s / 4.464x10¹⁴s⁻¹

λ = 6.716x10⁻⁷m

As 1m = 1x10⁹nm:

6.716x10⁻⁷m * (1x10⁹nm / 1m) = 671.6nm

Right answer is:

Answer:

4.58×10^3

3.72×10^7

Explanation:

3.8×10^2 =380

+ 4.2×10^3=4200

= 4580 = 4.58×10^3

Answer:

c. 64 grams

Explanation:

What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.

Answer: 40.3 L

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]

[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]  

According to stoichiometry :

1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]

Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex]  of [tex]CO[/tex]

Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]

Thus 40.3 L of CO is produced.

Answer:

The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere.

Explanation:

Answer:

sun shine

Explanation:

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time

Answer:

lithium

Explanation:

this is because lithium has a valency of 1 and oxygen has a valency of 2 thereby exchanging valency to create Li²0

Answer:

Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water

Answer:

How much heat energy required to convert following?

How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?

Specific Heat of Ice - 2.09 j/g * c

This is how I did it and the answer is wrong...Please check and correct me

Q = m * Cice * Change in Temp

Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj
