Answer:
1.08 grams of nitrogen
Explanation:
Thermally ammonium perchlorate dissociate as shown in figure.
Thus as per equation two moles of ammonium perchlorate will give four moles of water, two moles of oxygen, one mole of chlorine and one mole of nitrogen,
The molar mass of ammonium perchlorate = 117.5g/mol
Two moles of ammonium perchlorate = 2X 117.5 = 234 g
The molar mass of nitrogen = 28g
thus 234 grams of ammonium perchlorate will give 28 grams of nitrogen
Hence 9 grams of ammonium perchlorate will give 1.08 grams of nitrogen
Answer: kindly check explanation
Explanation:
Given the following :
Measured density of copper block:
8.6+/-0.2 g/cm3
True density = 8.96g/cm3
Standard deviation = 0.4g/cm
a. What is the high and low number of the confidence interval range?
High : 8.6 + 0.2 g/cm3 = 8.8g/cm³
Low : 8.6 - 0.2 g/cm3 = 8.4g/cm³
Does the true value fall within the confidence interval? NO
Actual density = 8.96g/cm³ doses not lie in between (8.4 - 8.8)g/cm³
B.) High and low of the standard deviation range?
High = 8.6 + 0.4 = 9.0g/cm³
Low = 8.6 - 0.4 = 8.2g/cm³
Value falls within range of the true density value of copper block.
8.96g/cm³ falls in-between (8.2-9.0)g/cm³
