Answer:

3.398x10^{-10}km^2

Explanation:

Hello!

In this case, since this is a two-step conversion, we first need to compute the m² and then the km² as shown below:

3.398cm^2*(\frac{1m}{100cm} )^2=3.398cm^2*\frac{1m^2}{1x10^4cm^2} =3.398x10^{-4}m^2

Now from m² to km²:

3.398x10^{-4}m^2*(\frac{1km}{1000m} )^2=3.398x10^{-4}m^2*\frac{1km^2}{1x10^6m^2}=3.398x10^{-10}km^2

Best regards!

Two protons and two neutrons are released as a result of this reaction. mc017-1.jpgRn mc017-2.jpgPo + ? Which particle is releas
Dovator [93]
The nuclear reaction occurring is known as alpha-decay, and during this process, an alpha particle is released from a heavy radioactive nucleus to form a lighter more stable nucleus. The alpha particle is equivalent to a helium nucleus, which means it contains 2 protons and two neutrons (net charge of +2)
The decay equation is:
Rn → Po + α

Hi guys, my question is:
guapka [62]

Answer:

See Explanation Below

Explanation:

A) The rate law can only be on the reactant side and you can only determine it after you get the net ionic equation because of spectators cancelling out. So in this case the rate law is k=[CH3Br]^1 [OH-]^1. The powers are there because the rxn is first order.  

B) Since the rxn is first order anything you do to it will be the exact same "counter rxn" per say so since you are decreasing the OH- by 5 the rate will decease by 5

C) The rate will increase by 4 since you are doubling both you have to multiply them both.

A student wants to collect data during an experiment about the transfer of kinetic energy in a sample of water and ice. Which to
erastova [34]

Given what we know, the tool in question that will help the student collect data regarding the transfer of kinetic energy between water and ice would be a thermometer.

<h3>How does the thermometer measure kinetic energy?</h3>

It does not do so directly. However, kinetic energy in water molecules is reflected in the temperature of the water. When water molecules increase their kinetic energy and move more, they become hotter. Increased or decreased heat is an indirect way to measure the transfer of kinetic energy in water.

Therefore, given that the temperature of the water is a reflection of the transfer of kinetic energy happening, we can confirm that the tool that will help the student collect the data needed is a thermometer.
