A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function.
While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.

Calculate how many grams of sodium hypochlorite can be theoretically formed when 1.23 mol of sodium hydroxide is combined with 1

elixir [45]

Answer:

45.78 g NaClO

Explanation:

The reaction that takes place is:

2NaOH + Cl₂ → NaCl + NaClO + H₂O

In order to react completely, 1.36 moles of chlorine would require (2*1.36) 2.72 moles of NaOH. There are more moles than that, so NaOH is the limiting reactant.

We calculate the moles of NaClO formed, from the limiting reactant:

1.23 mol NaOH * $\frac{1molNaClO}{2molNaOH}$ = 0.615 mol NaClO

Finally we convert NaClO moles to grams, using its molecular weight:

0.615 mol NaClO * 74.44 g/mol = 45.78 g NaClO

Which of the following mass units is the largest? a) 1 cg b) 1 dg c) 1 mg d) 1 ng

N76 [4]

Answer: option b) 1 dg

Explanation:

1) These are the different equivalences of those quantities:

a) 1 g = 100 cg ⇒ 1 cg = 0.01 g

b) 1 g = 10 dg ⇒ 1 dg = 0.1 g

c) 1 g = 1000 mg ⇒ 1 mg = 0.001 g

d) 1g = 10⁹ g ⇒ 1 ng = 10 ⁻⁹g

2) Now that you have all the masures in grams you can compare:

0.1g > 0.01g > 0.001g > 10 ⁻⁹g

3) So, the largest value is 0.1g which is 1 dg.

How many grams are equivalent to 1.80 x 10^-4 tons? (English tons)

konstantin123 [22]

Answer:

163.44 g

Explanation:

We know that one ton is equal to 2000 lbs and one lb is equal to 454 grams.

Solution:

1.80 × 10∧-4 ton× 2000 lb/ton× 454 g/lb

1.80 × 10∧-4 ton× 2× 10³lb/ton× 454 g/lb

1634.4 g/ 10 = 163.44 g

How many grams of baf2 are in 3.7 moles of baf2

Mice21 [21]

To convert moles to gram multiply 3.7 moles of BaF2 to the molar mass of BaF2

BaF2 molar mass = 175.326

3.7 moles x 175.326g = 648.70g BaF2
