If 5 ml of 0.5 M NaOH is added to 20 ml each of Buffer b and buffer c. Both of the buffers' pHs won't change since a buffer has a property that if it is added to another solution, acidic or basic, its pH won't change.
Answer:
1.0 L
Explanation:
Given data
- Initial volume (V₁): 0.35 L
- Initial concentration (C₁): 2.0 M
- Final concentration (C₂): 0.70 M
John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
V₂ = C₁ × V₁ / C₂
V₂ = 2.0 M × 0.35 L / 0.70 M
V₂ = 1.0 L
Answer is: between the carbon atom and the oxygen atom in a molecule of methanal there are two (2) <span>pairs of electrons.
Methanal or formaldehyde (H</span>₂C=O)<span> </span><span>is the simplest of the </span><span>aldehydes.
In methanal, bond between carbon and oxygen is double covalent bond (one sigma and one pi bond), which means there are four shared electrons or two pair of electrons.</span>
The only thing you need to put the followings into correct order is to remember that the smalles mass - the less volume it has. So, accordnig to this, the order should be like that : An ice crystal- A water molecule-An oxygen atom-The electron cloud-<span>An oxygen nucleus. Hope you will find it helpful!</span>
