Answer:

My old acc got banned

Explanation:

Explanation:

1. Find the empirical formula of a compound that has 36.84% of Nitrogen (N), 63.16% of Oxygen (O).

Secondly, Find molar mass of each component: N=14.0067, O=15.9994

Thirdly, convert to moles: N=2.6301698472874, O=3.9476480368014

Then find smallest mole value: 2.6301698472874

Divide all components my smallest value: N=1, O=1.5009099282591

Then divide by fractional component of each mole value: N=1.9963668986866, O=2.9963668986866

Round to closest whole numbers: N=2, O=3

Lastly, combine to get the empirical formula:N2O3

Answer:

H2

Explanation:

H (or hydrogen), being a halogen, as an atom, has 7 valence electrons. This means that it naturally bonds with another atom of the same isotope in order to reach the desired total of valence electrons: 8.

So... H+H = H2. EZ

Answer:

its all of them

Explanation:

i just did it lol but just incase, "Molecules are made of two or more atoms that are chemically bonded together. The atoms can be of the same element or of different elements. Therefore, H2, CO2, SiO2, and NH3 are all molecules."

Answer:

c6h12o6 + 6o2 = 6co2 + 6h20

Explanation:

c6h12o6 + 6o2 = 6co2 + 6h20

0 = 18 18

h = 12 12

c = 6 6

Answer:

The correct answer is 639 L H₂

Explanation:

We use the ideal gas equation:

We have the following data:

n = 28.3 mol

T= 297 K

P= 1.08 atm

R= 0.082 L.atm/K.mol (gas constant)

We introduce the data in the gas equation to calculate the volume (V):

PV=nRT

⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L

Therefore, the correct option is  639 L H₂

Answer:

639 L H2

Answer:

"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."

Explanation:

Answer:

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.

Explanation:

The transfer of energy between systems through work is the expansion of gas in a steam engine. By doing work or by transferring heat, energy can be transferred. Therefore, option A is correct option.

Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy requirement is necessary to move any object so work has to be done by the gas to the piston.

Heat can be transferred by three ways radiation, convention or conduction. In conduction, direct contact of two body is necessary for transfer of molecules. When we touch a shopping cart in the grocery store parking lot, then conduction is the process by which heat is transferred between our hand and the handle.

Therefore, the option A is correct option that is conduction.

Answer:

D) Stream

Explanation:

Answer:

a) both their average kinetic energy and temperature will be the same

Explanation:

Temperature is the measure of the average kinetic energy of a system. As temperature increases, so will kinetic energy. As kinetic energy increases, speed increases. As one decreases, so does the other. When two objects are in contact with each other, their molecules will exchange energy and cause an eventual equilibrium of temperature and kinetic energy.

i did it and got it right

Explanation:

The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.

Answer:

a.

[tex]K=\frac{[BaO]^2}{[Ba]^2[O_2]}[/tex]

b.

[tex]K=\frac{[MgO]^2}{[Mg]^2[O_2]}[/tex]

c.

[tex]K=\frac{[P_4O_{10}]^2}{[P_4][O_2]^5}[/tex]

Explanation:

Hello!

In this case, since the equilibrium expression is set up by dividing the products over the reactants and powering to the stoichiometric coefficient, we can proceed as follows:

a. 2 Ba + O2 ⇌ 2 BaO.

[tex]K=\frac{[BaO]^2}{[Ba]^2[O_2]}[/tex]

b. 2 Mg + O2 ⇌ 2MgO

[tex]K=\frac{[MgO]^2}{[Mg]^2[O_2]}[/tex]

c. P4 + 5 O2 ⇌ P4O10

[tex]K=\frac{[P_4O_{10}]^2}{[P_4][O_2]^5}[/tex]

Answer:

CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."

Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!

Answer:

Pb(NO3)2(aq) + 2NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)

Explanation:

Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)

This is how it starts out.

Left:

Right

So the place to start with this equation is to bring the Cls up to 2

Pb(NO3)2(aq)+2NaCl(aq) -> NaNO3(aq)+PbCl2(s)

But the Nas are now out of kilter.

Pb(NO3)2(aq)+ 2NaCl(aq) -> NaNO3(aq)+PbCl2(s)

Now the right has a problem. There's only 1 Na

Pb(NO3)2(aq) + 2 NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)

Check it out. It looks like we are done.
