Be 2+ is the charged ion of Be
-same amount of protons and neutrons, but has 2 less electrons, giving it full valence shell and + 2 charge
Just put "One can't describe the motion of particles, due to quantum mechanics particles don't take form until they're measured and even once they are there is no way of knowing if that is their actual form".
The good thing about studying Astrophysics is that there is always a way to correctly make a question unanswerable.
The amount of CO that would be required to generate 635 g of CO2 will be 404.14 g
<h3>Stoichiometric problem</h3>
First, let us get the equation of the reaction:
From the equation, we can see that the mole ratio of CO to that of CO2 is 1:1.
635 g of CO2 is to be generated.
Mole of 635 g CO2 = mass/molar mass = 635/44.01 = 14.43 moles
Thus, the equivalent mole of CO required will also be 14.43 moles.
Mass of 14.43 moles CO = moles x molar mass = 14.43 x 28.01 = 404.14 g
Hence, 404.14 g of CO will be required to produce 635 g of CO2

Answer: salicylic acid ( C7H6O3 ) is a covalent molecule.
Salicylic acid is used on the skin to treat psoriasis and other dry, scaly skin conditions. This medication is also used to help remove dead skin from warts, the palms of the hands, and the soles of the feet.
Answer:
- It only allows certain materials to leave the cell.
- It only allows certain materials to enter the cell.
- It helps the cell get rid of waste.
Explanation:
The cell membrane is a flexible membrane made up of proteins and lipids. It is selectively permeable (allowing only certain materials to enter or leave the cell) and plays a great role in selective absorption of materials (such as food nutrients, antibodies, waste products) entering or leaving the cell.
Also, it helps to protect the cell.
