Answer:
Okay so set up an equation for what's happening
_C + _H + _Cl + O2 --> _CO2 + _H2O
0.451g of CO2. Convert to moles by using the molar mass of CO2 which is 44 g/mol. Now look at the ratio between Carbon and Oxygen in CO2. It's 1C:2O You just want to find C.. so do the number of moles CO2 and multiply it by 1 since the ratio says 1 carbon atom. Now you have moles of carbon. Put this number aside for later.
Do the same thing with H2O. Convert to moles by using the molar mass of H2O which is 18 g/mol. Now look at the ratio between Hydrogen and Oxygen. It's 2H:1O You just want H.. so do the number of moles of H2O and multiply it by 2 since there's 2 hydrogen atoms. Now you have the moles of hydrogen & put this number aside for later
Lastly, you need to find the chlorine. uuhhh I cant figure this part out
Explanation: ..
I hope I helped lol!
Answer: Fundamental, Key, vital, crucial
Explanation:
The correct option is B.
Acceleration is defined as the rate of velocity of a body per unit time; that is, acceleration is given by the ratio of velocity and time. Looking at the graph given above, it can be seen that, the two runners started with different initial velocity; Beverly started with the initial velocity of 15 m/s while Carl started with the initial velocity of 10 m/s. For the rest of the race, the two runners maintains similar acceleration but Beverly won because her initial velocity was higher.
