Male chromosome is XY. Female is XX. Answer A is XX, answer B is XY, the child will be a male. Father passes down the chromosome.
<h3><u>Answer</u>;</h3>
No, a precipitate does not form
<h3><u>Explanation</u>;</h3>
- Precipitation involves mixing or combining solutions that contain soluble ionic compounds to form an insoluble ionic compound by a reaction.
- Sodium acetate and ammonium sulfate are both soluble ionic compounds, which implies that they exist as ions in aqueous solution.
- <em><u>When they combine they form NH4CH3COOH and sodium sulfate, Na2SO4, which are both soluble salts, as all salts of ammonium and sodium are soluble.</u></em>
- <em><u>Both ammonium acetate and sodium sulfate are soluble because there are no anions that can form an insoluble solid with NH4+ and Na+ cations. </u></em>
Given :
A student has a 1 g sample of each of the following compounds: NaCl, KBr, and KCl.
To Find :
The samples in order of increasing number of moles in the sample.
Solution :
Molecular mass of NaCl, KBr, and KCl is 58.5 g/mol , 119 g/mol and
74.5 g/mol respectively .
Moles of NaCl , 
.
Moles of KBr , 
.
Moles of KCl , 
.
The order of moles in increasing order is :
KBr , KCl and NaCl .
Hence , this is the required solution .
