You may tell when a solution os formed when the item or particle, such as sugar or salt,
dissolves completely in the solvent, such as water. 

Basically, you know when a solution is formed when the material you have placed in the solvent disappears :P

2CO + O2 --> 2CO2
GREYUIT [131]

Answer:

10 L of CO₂.

Explanation:

The balanced equation for the reaction is given below:

2CO + O₂ —> 2CO₂

From the balanced equation above,

2 L of CO reacted to produce 2 L of CO₂.

Finally, we shall determine the volume of CO₂ produced by the reaction of 10 L CO. This can be obtained as follow:

From the balanced equation above,

2 L of CO reacted to produce 2 L of CO₂.

Therefore, 10 L of CO will also react to produce 10 L of CO₂.

Thus, 10 L of CO₂ were obtained from the reaction.

Todd drives west to work;54km on way in 1.5hours and then drives home in 2hrs. What is his velocity on the way to work? What is
Nataly [62]

Answer:

Explanation:

Velocity ​​is a physical quantity that expresses the relationship between the space traveled by an object, the time taken for it and its direction. In other words, velocity is associated with the change of position of a body over time.

Its unit in the International System of Units is the meter per second (\frac{m}{s}), but it can also be expressed in \frac{km}{hr}

So, in this case, the speed on the way to work will be:

velocity=\frac{54 km}{1.5 hours}

velocity= 36 \frac{km}{hr}

The velocity on the way back home will be:

velocity=\frac{54 km}{2 hours}

velocity= 27 \frac{km}{hr}
