Answer: Option (B) is the correct answer.
Explanation:
According to Le Chatelier's principle, any disturbance causes in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
For example, 
When we increase the temperature then the reaction will shift in a direction where there will be decrease in temperature.
This, means that the reaction will shift in the backward direction.
Thus, we can conclude that if the reaction is at equilibrium and the temperature increases, the equilibrium will shift so that there is more nitrogen dioxide.
Answer:
Rb<K<Ga<As<Se<S
Explanation:
We must remember that first ionization energy decreases down the group and increases across the period.
First ionization energy decreases down the group because of the addition of more shells which increases the distance between the nucleus and the outermost electron. Hence, Rb has a lower ionization energy that K.
Across the period, increase in the size of the nuclear charge causes the pull of the nucleus on the outermost electrons to increase thereby increasing the ionization energy. Hence ionization energy increases across the period. For this reason, the ionization energy of Ga<As<Se as shown.
OOH! I know photosynthesis and I have been doing it in school. So the Glucose and oxygen combine to help make the photosynthesis AND it is so important to not forget about Carbon Dioxide and all the features for that because a plant needs carbon dioxide while we need oxygen and plants give out oxygen so that humans can have it and we breathe out carbon dioxide so that plants can have it. We pretty much just help each other out. I plants weren't there than humans wouldn't be there. Hope this helps!
<h2>Answer:</h2>
A) 3 atoms - 1 atom of Carbon and 2 atoms of oxygen.
B) 2 atoms of Nitrogen.
C) 6 atoms - 2 Carbon atoms, 2 Hydrogen atoms, and 2 Oxygen atoms.
<h2>Explanations:</h2>
A molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound. Molecules are made up of atoms.
According to the following information, we are to find the number of atoms in the given molecules.
A) For carbon dioxide CO₂, this molecule is made of 3 atoms - 1 atom of Carbon and 2 atoms of oxygen.
B) For the compound N₂, this molecule is made up of 2 atoms of Nitrogen.
C) For the compound CHCOOH, this molecule consists of 6 atoms - 2 Carbon atoms, 2 Hydrogen atoms, and 2 Oxygen atoms.
Boron (B) has 3 electrons in the outer shell.
Barium (Ba) has 2 electrons.
Phosphorus (P) has 5 electrons.
Manganese (Mn) has 2 electrons.
The answer is C) P (phosphorus).
