Photosynthesis is how producers make their own food
Answer:
(not sure if this helps but)
The number of electrons in a neutral atom is equal to its proton.
Explanation:
The number of protons in a neutral atom are equal to its number of protons. It is also equal to its atomic number.
hope it helps :)
Answer:
The reaction will shift leftwards, towards the formation of more cyclohexane at 25 °C
Explanation:
Hello,
In this case, for the given chemical reaction, we can write the law of mass action (equilibrium expression) as shown below:
![Kc=\frac{[CH_3C_5H_9]}{[C_6H_{12} ]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BCH_3C_5H_9%5D%7D%7B%5BC_6H_%7B12%7D%20%5D%7D)
Thus, since Kc < 1, we can conclude there are more moles of cyclohexane at equilibrium (denominator is greater than numerator), therefore, the reaction will shift leftwards, towards the formation of more cyclohexane at 25 °C.
Best regards.
You will need Periodic Table for this problem.
As we know, the number of protons specifies Atomic number. So, the atomic number for this element is 19.
Now, element having 19 protons must have 19 electrons, So, writing electronic configuration for 19 electrons,
1s², 2s², 2p⁶, 3s², 3p⁶, 4s¹
So, valence shell is 4, means element is present in 4rt period. And number of electrons in 4rth shell are 1. Means element belong to group 1.
Take periodic table go to period 4 and group 1. Its Potassium (K).
Answer: 257.47 K
Work:
-15.68°C + 273.15= 257.47K
