Answer:
AX+BY=AY+BX
Explanation:
Double-replacement reactions are represented by the general equation AX+BY=AY+BX a reaction in which a substance combines with oxygen, releasing a large amount of energy in the form of light and head
Plants are the producers — they use the sun's energy to convert water and carbon dioxide into plant material via photosynthesis. ... A producer is a living thing that makes its own food from sunlight, air, and soil. Green plants are producers who make food in their leaves.
Answer:
V₁ = 12.1 mL
Explanation:
Given data:
Volume of NaOH required to neutralize = ?
Molarity of NaOH = 4.8 M
Volume of HCl = 20 mL
Molarity of HCl = ?
Solution:
Chemical equation:
HCl + NaOH → NaCl + H₂O
In neutralization reaction the equal amount of H⁺ from acid and OH⁻ from base react to form water and salt is also formed.
Formula:
M₁V₁ = M₂V₂
M₁ = molarity of NaOH
V₁ = Volume of NaOH
M₂ = molarity of HCl
V₂ = volume of HCl
Now we will put the values.
4.8 M × V₁ = 2 M × 29 mL
4.8 M × V₁ =58 M. mL
V₁ = 58 M. mL / 4.8 M
V₁ = 12.1 mL
