Complete question:
The student performs a second titration using the 0.10MNaOH(aq) solution again as the titrant, but this time with a 20.mL sample of 0.20MHCl(aq) instead of 0.10MHCl(aq).
1. The box below to the left represents ions in a certain volume of 0.10MHCl(aq). In the box below to the right, draw a representation of ions in the same volume of 0.20MHCl(aq). (Do not include any water molecules in your drawing.)
Answer:
The concentration of H+ and Cl- will be doubled.
Explanation:
See the attached photo for the representation of ions in the same volume.
In order to answer this question we must look at the image which I have attached.
The red atoms refer to oxygen atoms, the grey atoms are carbon atoms and the blue atoms are nitrogen. Therefore, the equation from the image suggests:
2CO + 2NO → 2CO₂ + N₂
Looking closely at the options given, several of them could be eliminated immediately since they are not balanced equations like B, C and E. Therefore, only A or D could be the answers.
The answer is option

Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
