Answer:  the answer is C. The warmer object's particles speed up

the cooler object's particles.

Explanation:    Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.

Hot spot volcano is the type of volcano which is formed at a weak spot in

the middle of a plate.

Hot spot volcano is an area in the Earth crust which is characterized by large

amount of heat flow in the area due to the volcanic activity. Hot spot  

volcano is formed at the middle of the plate as against junctures in which

other types are formed.

The weak spot is what gives rise to the unusual heat flow which makes hot

spot volcano most appropriate.

Answer:

Explanation:

The molarity of the diluted standard solution is obtained by calculation to be 0.015 M.

Recall the dilution formula;

C1V1 = C2V2

C1 = Initial concentration = 0.1140 M

V1 = initial volume =  6.50mL

C2 = Final concentration = ?

V2 = Final volume = 50.0mL

Making C2 the subject of the formula and substituting values;

C2 = C1V1/V2

C2 = 0.1140 M ×  6.50mL/50.0mL

C2 = 0.015 M

Answer:

Time of earthquake, magnitude and velocity, and type of seismic waves

Explanation:

Seismometers allow us to detect and measure earthquakes by converting vibrations due to seismic waves into electrical signals, which we can then display as seismograms on a computer screen. Seismologists study earthquakes and can use this data to determine where and how big a particular earthquake is.

True statement for a nuclear reactions is that it changes the identity of the element.

Nuclear reactions are those reactions in which changes in the nucleus of atoms take place in the form of fission and fussion.

Hence identity of element changes.

Answer:

Percent yield is the maximum amount of product that can be formed in a reaction. Matter cannot be created or destroyed according to the law of conservation of mass, so you cant have over 100%.

Explanation:

Answer:

20

Explanation:

You need 4 times the amount of B, compared to a (there is a 3A:12B which reduces to 1:4), so 4 times 5 is 20.

The particle released in the reaction has been an alpha particle. Thus, option A is correct.

The release of protons and neutrons in a reaction has been nuclear reactions. The reactions results in the change in the atomic mass of the atom, with the formation of new atom. The extra mass has been released in the form of energy.

The release from the given reaction has been:

[tex]\rm ^{222}_{66}Rn\;\rightarrow\;^{218}_{84}Po\;+\;^A_ZX[/tex]

Where, X has been the particles that has been released with the nuclear reaction. The superscript A has been the Mass of particle, and subscript Z has been the atomic number.

According to the law of conservation, the mass has been constant on both the product and the reactant side. Thus, the mass and atomic number of eliminated particles has been given as:

[tex]\rm 222=218+A\\A=222-218\\A=4[/tex]

The atomic mass of the particle has been 4.

[tex]\rm 86=84+Z\\Z=86-84\\Z=2[/tex]

The atomic number of the particle has been 2.

The element with atomic mass 4, and atomic number 2 has been the Helium particles, [tex]\rm ^4_2He[/tex]. It has been an alpha particle. Thus, the particle released in the reaction has been an alpha particle. Thus, option A is correct.

Explanation:

For this problem you want to use dimensional analysis and cancel out your molecules of sugar and be left with moles of sugar. We know that 1 mole (of anything) = 6.022 x 10 ^ 23 molecules, so we should use that conversion to help us. Start with 9.12 x 10 ^23 molecules and divide by 6.022 x 10 ^ 23 molecules, and you will be left with moles.

When n increases, T decreases, so, n is 1 for and 0.5 for , implying that is hotter.

The temperatures of the gases will not be equal.

∵V is the same for both

∴T= same for both.

When n increases, T decreases, so, n is 1 for hydrogen gas and 0.5 for  oxygen gas ,implying that oxygen gas will have more temperature than hydrogen gas since its number of moles are lower than hydrogen gas.
