Answer:
Oxybenzone contains ether, phenol and ketone (-CO) functional group alonq with two aromatic rings.
Explanation:
Answer:224
Explanation:
We should answer it with Stoichiometry
We say: 20 g H2× (1 mol/ 2g)× ( 22.4 lit/ 1 mol) = 224
Means: we have 20 grams and every 2g H2, equals to 1 mol of it and every 1 mol of H2, equals to 22.4 lit( because of STP)
hope you got this:)
Answer:
88,7 mL of solution
Explanation:
Molarity (Represented as M) is an unit of chemical concentration that is defined as the ratio between moles of solute per liters of solution, that is:
Molarity = moles of solute / Liters of solution
If molarity of KCN solution is 0,0820M and moles of KCN are 7,27x10⁻³ moles:
0,0820M = 7,27x10⁻³ moles / Liters of solution
Liters of solution = 0,0887L = <em>88,7 mL of solution</em>
I hope it helps!
%C= 12/12 + 2·16=0,273=27,3%.
Answer:
The answer to your question is Single replacement
Explanation:
Data
Chemical reaction
Na + H₂O ⇒ NaOH + H₂
Single replacement is a chemical reaction in which a metal replaces the cation of a compound.
Decomposition is a chemical reaction in which a compound forms 2 or more products.
Double replacement in this chemical reaction two compounds react interchanging their cations and anions.
Combustion in this chemical reaction the reactants must be a compound with carbon and the other oxygen and the products must be carbon dioxide and water.
