If this is asking if the equation is balanced, than the answer is true
M1V1 = M2V2
225M1 = (2)(120)
225M1 = 240
M1 = 240/225 = 1.066 M C
Answer:
Fe + 3NaBr → FeBr₃ + 3Na
Explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Chemical equation:
Fe + 3NaBr → FeBr₃ + 3Na
This chemical equation shows the single replacement reaction. Iron replace the sodium and react with bromine.
All other options are incorrect because,
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
It is double replacement reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O
This reaction equation shows combustion.
H₂O + CO₂ → H₂CO₃
This is synthesis reaction.
Answer:
The formula of Organic acid is as follow,
R-COOH
Explanation:
The class of organic acids is called Carboxylic Acids. In above general structure, R is alkyl group and can vary. While -COOH is the functional group.
Carboxylic Acids has the tendency to loose protons and their pKa value depends upon the alkyl group. For example the pKa value of Acetic acid (R = -CH₃) is 4.7. The driving force for this acidity is the stability of carboxylate (conjugate base) due resonance. i.e
RCOOH ⇄ RCOO⁻ + H⁺
Where;
RCOO⁻ = Carboxylate Ion (Conjugate base)
Answer: UV Rays can't travel through glass, making it impossible to get a suntan because your body won't be able to respond if there is no UV getting to it.
Explanation: Glass absorbs and deflects a lot of UV light because the wavelengths aren't small enough to pass through and as a result, your body can't undergo its natural response of producing melanin, because the proteins activated by the UV damage won't be enacted.
