Answer : The value of
for the reaction is, -565.6 kJ
Explanation :
First we have to calculate the molar mass of CO.
Molar mass CO = Atomic mass of C + Atomic mass of O = 12 + 16 = 28 g/mole
Now we have to calculate the moles of CO.
![\text{Moles of }CO=\frac{\text{Mass of }CO}{\text{Molar mass of }CO}=\frac{1g}{28g/mole}=\frac{1}{28}mole](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DCO%3D%5Cfrac%7B%5Ctext%7BMass%20of%20%7DCO%7D%7B%5Ctext%7BMolar%20mass%20of%20%7DCO%7D%3D%5Cfrac%7B1g%7D%7B28g%2Fmole%7D%3D%5Cfrac%7B1%7D%7B28%7Dmole)
Now we have to calculate the value of
for the reaction.
The balanced equation will be,
![2CO(g)+O_2(g)\rightarrow 2CO_2(g)](https://tex.z-dn.net/?f=2CO%28g%29%2BO_2%28g%29%5Crightarrow%202CO_2%28g%29)
From the balanced chemical reaction we conclude that,
As,
of CO release heat = 10.1 kJ
So, 2 mole of CO release heat = ![2\times 28\times 10.1=565.6kJ](https://tex.z-dn.net/?f=2%5Ctimes%2028%5Ctimes%2010.1%3D565.6kJ)
Therefore, the value of
for the reaction is, -565.6 kJ (The negative sign indicates the amount of energy is released)
19. The atomic number is the same as protons and electrons unless it have a - or a + charge the electrons are going to change
<u>Answer:</u> The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
<u>Explanation:</u>
Force is defined as the product of object's mass and acceleration.
Mathematically,
F = ma ......(1)
or,
a = F/m .....(2)
where,
F = Force exerted on an object = 60N
m = mass of an object = 30kg
a = acceleration of the object = ?
Putting values in above equation, we get:
a = 60 kg.m/s^2/30 kg = 2m/s^2
The acceleration of the car is 2m/s^2.
From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.
And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.
Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

Hope that this helps you ;-)
Aspartame produces 4 kilocalories of energy per gram when metabolized, While table sugar produces 3.9 kilocalories. However, aspartame is approximately 200 times sweeter than table of sugar, so it is consumed in much smaller doses. Then we can say that they're pretty much the same
