Which of the following chemical formulas represents a molecule?
H2 CO2 SiO2 NH3
Answers
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."

Write the equilibrium expressions for each of the following equilibria:
a. 2 Ba + O2 ⇌ 2 BaO
b. 2 Mg + O2 ⇌ 2MgO
c. P4 + 5 O2 ⇌ P4O10
Answers
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]

Why the bond in water molecule os polar covalent bond, while than in chlorine molecule is pure covalent bond? Give reason?
Answers
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.

When two objects of different temperatures are placed in contact with one another, eventually: (choose one option from below)
a) both their average kinetic energy and temperature will be the same
b) their average kinetic energy will be the same
c) neither their average kinetic energy and temperature will be the same
d) their temperature will be the same
Answers
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.

1. You touch a shopping cart in the grocery store parking lot. What type of heat
transfer is happening between your hand and the handle?
Conduction
b. Convection
C. Radiation
d. Thermal Equilibrium
Answers
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.
What is energy transfer?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.

Balance this equation. Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)
Answers
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:
2 NO3s1 Pb1 Na1 ClRight
1 Na1 NO31 Pb2 ClSo 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

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.

How many grams are in 8.50 e 23 formula units of NaCl?
a)82.5 g
b)8.25 g
c)85.0 g
d)91.5 g
Answers
Answer:
a)82.5 g
Explanation:
To solve this problem we will use Avogadro's number, which states the number of formula units per mole.
8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 molThen we convert 1.41 moles of NaCl to grams, using its molar mass:
1.41 mol NaCl * 58.44 g/mol = 82.4 gThe closest answer is option a).

A reaction is expected to produce 28.3 moles of hydrogen gas. If the hydrogen is collected at 297 K and 1.08 atm, what is the volume? 305 L H2 639 L H2 948 L H2 1,240 L H2
Answers
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
