Which of the following statements is true?

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.

Answer:

c6h12o6 + 6o2 = 6co2 + 6h20

Explanation:

c6h12o6 + 6o2 = 6co2 + 6h20

0 = 18 18

h = 12 12

c = 6 6

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."

Explanation:

175 cm³ instead of 175 cm.

Answer:

297.5 cm³

Explanation:

From the question;

Initial volume; V1 = 175 cm³

Initial temperature; T1 = 25°C

Final temperature; T2 = 42.5°C

From Charles law we can find the volume V2 from the equation;

V1/T1 = V2/T2

Making V2 the subject gives;

V2 = V1 × T2/T1

V2 = (175 × 42.5)/25

V2 = 297.5 cm³

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:

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.

Answer:(D) different number of neutrons per atom

Explanation: Honestly, I just looked it up on Socratic.

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:

To find the symbol of the element, you have to use the periodic table.  

The mass number is the number of protons and neutrons in the atom.  

The atomic number is the number of protons in the atom.

You can find the number of protons from the periodic table.

You can find the neutrons by subtracting the mass number by the number of protons in the atom.

Unless you have an ion, you will have the same amount of electrons as you do protons.

To write in nuclear notation, you write the chemical symbol with the mass number and atomic number shown in the attachment.  It is preferable to have the mass number and atomic number directly above each other.

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!!
