i think that the answer is D
Answer:
3
m/s2
0.2
m/s2
Explanation:
if F=ma, then a = F/m. The unit to measure acceleration is typically m/s2.
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).
![4.30g\text{ Ca\lparen OH\rparen}_2*\frac{1\text{ mol Ca\lparen OH\rparen}_2}{74g\text{ Ca\lparen OH\rparen}_2}*\frac{2\text{ moles HNO}_3}{1\text{ mole Ca\lparen OH\rparen}_2}*\frac{63.02g\text{ HNO}_3}{1\text{ mole HNO}_3}=7.32g\text{ HNO}_3](https://tex.z-dn.net/?f=4.30g%5Ctext%7B%20Ca%5Clparen%20OH%5Crparen%7D_2%2A%5Cfrac%7B1%5Ctext%7B%20mol%20Ca%5Clparen%20OH%5Crparen%7D_2%7D%7B74g%5Ctext%7B%20Ca%5Clparen%20OH%5Crparen%7D_2%7D%2A%5Cfrac%7B2%5Ctext%7B%20moles%20HNO%7D_3%7D%7B1%5Ctext%7B%20mole%20Ca%5Clparen%20OH%5Crparen%7D_2%7D%2A%5Cfrac%7B63.02g%5Ctext%7B%20HNO%7D_3%7D%7B1%5Ctext%7B%20mole%20HNO%7D_3%7D%3D7.32g%5Ctext%7B%20HNO%7D_3)
So, 7.32g of HNO3 are required.
