J1770 and J2788 must be referred to on the label of approved refrigerant recylcing machines. This encompasses all of the requirements of the outdated J2210 and covers both single circuit and dual refrigerant units.

Cerrena [4.2K]

Answer:

To sum it all up, you can get a virus on your iPad, but the chances of this happening are pretty slim. These chances go up quite a bit if you jailbreak your iPad and install apps not found in the App Store, but there are still very few of them out there.

John and Alex were asked to make a 0.70 M solution. John measure out .35 L from the 2.0 M solution before asking how much soluti

nasty-shy [4]

Answer:

1.0 L

Explanation:

Given data

Initial volume (V₁): 0.35 L

Initial concentration (C₁): 2.0 M

Final volume (V₂): ?

Final concentration (C₂): 0.70 M

John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₂ = C₁ × V₁ / C₂

V₂ = 2.0 M × 0.35 L / 0.70 M

V₂ = 1.0 L

Usimov [2.4K]

1. If horizontal layers of sedimentary rock have a vertical fault running through them, then they cab predict where the fault begame by matching up rock layers over distances.
2. Yes, because they it is use to determine an age on a specified chronology in archaeology and geology. They can use these data to prove their theories.

2. If the reaction of 5.75 moles of sodium with excess hydrofluoric acid is able to produce 2.49 mol H2, what is the percent yie

GuDViN [60]

Answer:

86.5%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

2Na + 2HF –> 2NaF + H2

Next, we shall determine the theoretical yield of the hydrogen gas, H2. This is illustrated:

From the balanced equation above,

2 moles of Na reacted to produce 1 mole of H2.

Therefore, 5.75 moles of Na will react to produce = (5.75 x 1)/2 = 2.88 moles of H2.

Therefore, the theoretical yield of Hydrogen gas, H2 is 2.88 moles.

Finally, we shall determine the percentage yield of Hydrogen gas, H2. This can be obtained as follow:

Actual yield of H2 = 2.49 moes

Theoretical yield of H2 = 2.88 moles

Percentage yield of H2 =.?

Percentage yield = Actual yield /Theoretical yield x 100

Percentage yield = 2.49/2.88 x 100

Percentage yield = 86.5%

Therefore, the percentage yield of Hydrogen gas, H2 is 86.5%.
