Answer:
7.32g of HNO3 are required.
Explanation:
1st) From the balanced reaction we know that 2 moles of HNO3 react with 1 mole of Ca(OH)2 to produce 2 moles of H2O and 1 mole of Ca(NO3)2.
From this, we find that the relation between HNO3 and Ca(OH)2 is that 2 moles of HNO3 react with 1 mole of Ca(OH)2.
2nd) This is the order of the relations that we have to use in the equation to calculate the grams of nitric acid:
• starting with the 4.30 grams of Ca(OH)2.
,
• using the molar mass of Ca(OH)2 (74g/mol).
,
• relation of the 2 moles of HNO3 that react with 1 mole of Ca(OH)2 .
,
• using the molar mass of HNO3 (63.02g/mol).

So, 7.32g of HNO3 are required.
Answer:
usage of trills and vibrato
Explanation:
earlier music used trills while later styles would use vibrato.
Answer:
A. A scientist investigates a mouse's growth in nature by watching the animal.
A field study is a raw collection of data, typically in the natural habit of the organism; hence why an experiment taken in a lab isn't a field study.
Answer:
<h2>Organic chemistry is the chemistry of carbon based compounds while biochemistry is the study of directly biologically relevant chemistry..</h2><h2>pls mark as brainliest</h2>
Answer:
Hence option C is correct.
Explanation:
the process is osmosis a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
so the answer for the this question will be There is a net flow of water from the 4% starch solution into the 10% starch solution because solvent (water) moving from low conc. (4 %) to high conc. (10%)
Hence option C is correct.
