How many moles of chlorine could be produced by decomposing 157g NaCl? 2NaCl --> 2Na+Cl2
Answers
By decomposing 157g of NaCl, approximately 1.35 moles of chlorine can be produced.
To determine the number of moles of chlorine that could be produced by decomposing 157g of NaCl, we need to use the molar mass of NaCl and apply stoichiometry.
The molar mass of NaCl is the sum of the atomic masses of sodium (Na) and chlorine (Cl), which is approximately 22.99 g/mol + 35.45 g/mol = 58.44 g/mol.
Now, we can calculate the number of moles of NaCl:
Moles of NaCl = Mass of NaCl / Molar mass of NaCl
Moles of NaCl = 157 g / 58.44 g/mol
Moles of NaCl ≈ 2.69 mol
According to the balanced equation 2NaCl → 2Na + Cl₂, we can see that for every 2 moles of NaCl, we produce 1 mole of Cl₂.
Therefore, using the stoichiometric ratio, we can calculate the number of moles of chlorine produced:
Moles of Cl₂ = (Moles of NaCl / 2) × 1
Moles of Cl₂ = 2.69 mol / 2
Moles of Cl₂ ≈ 1.35 mol
Thus, by decomposing 157g of NaCl, approximately 1.35 moles of chlorine can be produced.

According to Hebrews 11, what did Abraham believe God would do if Isaac was slain as a sacrifice? Please help me I need it for tonight!
Answers
Answer:
ABRAHAM DIDN’T THINK ISAAC WOULD DIE!
When they reached the mountain, Abraham told his servant, “Stay here with the donkey; I and the boy will go over there and worship and come again to you” . The text is careful to include both Abraham and Isaac in the return journey.
Or consider Isaac’s question about where the lamb for the sacrifice would come from. Abraham responds, “God himself will provide the lamb”. It seems Abraham prepared himself to do what God asked, but he expected something else to happen.
The author of the book of Hebrews gives us insight to Abraham’s thoughts. It says, “He considered that God was able even to raise [Isaac] from the dead” Instead of a resurrection, Abraham was spared the sacrifice.

Check all of the following below which describe experimental errors that would affect the percent chloride you report in your experimental results: ____________
a) The solid product was wet when you weighed the final mass
b) You added excess silver nitrate into the reaction mixture
c) The liquid collected from the filtration was cloudy
d) The transfer from the reaction beaker to the filter funnel was imperfect (you lost some of the reaction solution or some was left in the beaker)
e) Extra water was used to dissolve the original unknown solid
Answers
The options that describe the experimental errors that would affect the percent of chloride reported are:
B (You added excess silver nitrate into the reaction mixture) and D (The transfer from the reaction beaker to the filter funnel was imperfect).While performing experiments, there are some errors that occur which are generally known as experimental errors.
These experimental errors are the difference between the true measurement and what we measured.
There are three types of experimental errors they include:
systematic, random, and human error.Human errors occur due to carelessness of the observer.
Examples are:
when you added excess silver nitrate into the reaction mixture when the transfer from the reaction beaker to the filter funnel was imperfect due to lost of some of the reaction solution.Therefore, the options describe the experimental errors that would affect the percent of chloride reported are B and D.
