Assuming the same temperature and pressure for each gas, how many milliliters of carbon dioxide are produced from 16.0 mL of CO?
Vlada [557]

Answer:

V_{CO_2}=16.0mL

Explanation:

Hello,

In this case, given that the same temperature and pressure is given for all the gases, we can notice that 16.0 mL are related with two moles of carbon monoxide by means of the Avogadro's law which allows us to understand the volume-moles relationship as a directly proportional relationship. In such a way, since in the chemical reaction:

2CO(g)+O_2(g)\rightarrow 2CO_2(g)

We notice two moles of carbon monoxide yield two moles of carbon dioxide, therefore we have the relationship:

n_{CO}V_{CO}=n_{CO_2}V_{CO_2}

Thus, solving for the yielded volume of carbon dioxide we obtain:

V_{CO_2}=\frac{n_{CO}V_{CO}}{n_{CO_2}} =\frac{2mol*16.0mL}{2mol}\\ \\V_{CO_2}=16.0mL

Best regards.

The kinetic energy of an object can be determined using the equation , where is the kinetic energy, is the mass, and is the spee
Cloud [144]

Answer:

0.5kg

Explanation:

Given parameters:

Speed of the object  = 12m/s

Kinetic energy  = 36J

Unknown:

Mass of the object  = ?

Solution:

Kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;

     K.E = \frac{1}{2} m v²  

 Insert the parameters and solve;

    36  =  \frac{1}{2} x m x 12²

     36  = 72m

       m  = 0.5kg
