Answer:
well for me it's
Explanation:
The reflection of the seas
According to the balanced equation of the reaction:
2C2H2 + 5O2 → 4CO2 + 2H2O
So we can mention all as liters,
A) as we see that 2 liters of C2H2 react with 5 liters of oxygen to produce 4 liters of CO4 and 2 liters of H2O
So, when we have 75L of CO2
and when we have 2 L of C2H2 reacts and gives 4 L of CO2
2C2H2 → 4CO2
∴ The volume of C2H2 required is:
= 75L / 2
= 37.5 L
B) and, when we have 75 L of CO2
and 4CO2 → 2H2O
∴ the volume of H2O required is:
= 75 L /2
= 37.5 L
C) and from the balanced equation and by the same way:
when 5 liters O2 reacts to give 4 liters of CO2
and we have 75 L of CO2:
5 O2 → 4 CO2
?? ← 75 L
∴ the volume of O2 required is:
= 75 *(5/4)
= 93.75 L
D) about the using of the number of moles the answer is:
no, there is no need to find the number of moles as we called everything in the balanced equation by liters and use it as a liter unit to get the volume, without the need to get the number of moles.
The relation between force and mass and acceleration is
![Force = mass X acceleration](https://tex.z-dn.net/?f=Force%20%3D%20mass%20X%20acceleration)
The SI unit will be
Force = Newton
mass =kg
acceleration=![\frac{m}{s^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D)
thus
![acceleration = \frac{Force}{mass}](https://tex.z-dn.net/?f=acceleration%20%3D%20%5Cfrac%7BForce%7D%7Bmass%7D)
putting values
![acceleration=\frac{60 N}{12kg}=5\frac{m}{s^{2} }](https://tex.z-dn.net/?f=acceleration%3D%5Cfrac%7B60%20N%7D%7B12kg%7D%3D5%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D)
Thus the acceleration will be
![5\frac{m}{s^{2} }](https://tex.z-dn.net/?f=5%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D)
