Answer:
1 mole
Explanation:
To get the answer to this, we need to write the correct chemical equation:
HCl + NaOH ------》NaCl + H2O
As seen in the balanced chemical equation above, one mole of hydrochloric acid will react with one mole of sodium hydroxide to yield one mole of sodium chloride and one mole of water
Answer:
a) 965,1 lbf
b) 4,5 kg
c) 1,33 * 10^6 dynes
Explanation:
Mass of an object refers to the amount of mattter it cotains, it can be expressed it gr, kg, lbm, ton, etc.
Weight of an object refers to a force, and is the measurement of the pull of gravitiy on an object. It may be definide as the mass times the acceleration of gravity.
w=mg
In Planet Earth, the nominal "average" value for gravity is 9,8 m/s² (in the International System) or 32,17 ft/s² (in the FPS system).
To solve this problem we'll use the following conversion factors:
1 lbf = 1 lbm*ft/s²
1 N = 1 kg*m/s²
1 dyne = 1 gr*cm/s² and 1 N =10^5 dynes
1 ton = 907,18 kg
1 k = 1000 gr
a) m = 30 lbm
b) w = 44 N
First, we clear m of the weight equation and then we replace our data.
c) m = 15 ton
Answer:
The top curve/graph is exponential growth. All exponential growth graphs look like a J in a way! Hope that helped
You should get 5.05 x 10^23 moles.
Answer:
Strong broad peak around 3200-3600 cm-1 should be present
Strong peak around around 1700 cm-1 should be absent
Explanation:
Infrared spectroscopy is an analytical technique which is used for molecular structure characterization by identifying the functional groups present in a given molecule based on the absorption wavelength (or wavenumber).
In an IR spectrum the carbonyl group is associated with the C=O stretch which occurs as a strong peak around around 1700 cm-1. For alcohol the -corresponding O-H stretching frequency occurs as a strong broad peak between 3200-3600 cm-1.
Therefore, in the case of estradiol the presence a strong broad peak in the 3200-3600 cm-1 and the absence of the peak at around 1700 cm-1. would suggest that the transformation is complete.
