Answer: In the possible source of error goes: Changing two variables at once to increase rate of data collection, Taking turns with lab partners performing different tasks in an experiment, Measuring millimeters with an ordinary meter stick

In the good experimental practice goes: Measuring in standard metric units, Doing repetitive trials of the same experiment, changing the angle of a ramp in an experiment by constant intervals

Which of the following is true for the endothermic reaction Ba(OH)2(aq) + NH4NO3(aq) --> Ba(NO3)2(aq) + 2NH3(aq) + 2H2O(l)?

Alchen [17]

If it's an endothermic reaction, then that means heat is being added to the system therefore H>0. Entropy is disorder, and since there are more moles on the products side, entropy is increasing therefore S>0 as well.

2. If 1.204 X 1024 atoms of sodium is 20% of the total sodium atoms in sodium

GuDViN [60]

Answer:

584.2 g

Explanation:

Hello there!

In this case, since we know the 20% of the atoms correspond to sodium, we can compute the total atoms as shown below:

$\frac{1.204 x10^{24}}{0.2}=6.02x10^{24}atoms$

Which are also equal to 1 mol and the Avogadro's number of sodium chloride with a molar mass of 58.44 g/mol; thus, the grams of salt turn out to be:

$6.02x10^{24}atoms*\frac{1mol}{6.022x10^{23}atoms} *\frac{58.44g}{1mol}\\\\=584.2g$

Best regards!
