in the reaction :N2 + 3H2----2NH3 how many grams of H2 are needed to produce 1 mole on ammonia

Answers

Start with moles of ammonia you want to produce, then convert to how many moles of H2 you need to get one mole of ammonia, then convert that to grams :)

The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.

Calculation of the number of grams:

Here we begins the moles of ammonia for production after this it convert the number of moles of h2 for getting one mole of ammonia and then finally convert into grams

So it be like

[tex]= 1\ mol NH_3 \frac{3H_2}{2NH_3}\frac{1.01g }{1\ mol H_2}[/tex]

= 1.52 g Hz

Hence, The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.

Answer:

question 4. 69.19J

question 5. 40835.84J

Explanation:

question4.

heat needed = mass × specific heat capacity × change in temperature

= 9.3× 0.240×(52-21)

=69.192J

question 5.

heat added = 160× 4.184×(85-24)

10. Which of these elements is the most electronetative?
(10 Points)
Nitrogen
Calcium
Bromine
O Aluminum

Answers

it would be nitrogen
Out of the four Nitrogen is the most electronegative. Electronegative is basically determined by whichever atom is closest to F (the most electronegative)

Nitrogen is only a few electrons difference than Fluorine. Bromine is still quite electronegative but it has whole extra valence shells making it not as electronegative as nitrogen

When energy is released by the pack, what happens to the energy of the surroundings (outside the pack)?
a. The energy increases
b. The energy decreases
c. The energy stays the same

Answers

Answer:

a

Explanation:

i hope that's correct

The energy of the surroundings (outside the pack) will:

a. The energy increases, when energy is released.

Energy in the surroundings:

Energy is delivered to create bonds, which is the reason the enthalpy change for it is positive to break bonds. Energy is expected to break bonds. Particles are a lot more joyful when they are "wedded" and discharge energy since it is simpler and more steady to be seeing someone.

When energy is released, the energy in the surroundings will increase.

Thus, option a is correct.

To prepare 800mL of 1M phosphate buffer of pH 7.2 (PKa=7.1), by using salt = K2HPO4 and acid = KH2PO4, the quantity of salt required is

Answers

Answer:

78.04g of 0.448 moles must be added

Explanation:

Using H-H equation we can find the pH of the buffer:

pH = pKa + log [A⁻] / [HA]

Where pH is the pH of the buffer = 7.2

pKa = 7.1

[A⁻] = [K₂HPO₄]

[HA] = [KH₂PO₄]

Replacing:

7.2 = 7.1 + log [K₂HPO₄] / [KH₂PO₄]

0.1 = log [K₂HPO₄] / [KH₂PO₄]

1.2589 = [K₂HPO₄] / [KH₂PO₄] (1)

And as the  concentration of the buffer is:

1M = [K₂HPO₄] + [KH₂PO₄] (2)

Replacing (2) in (1):

1.2589 = 1M - [KH₂PO₄] / [KH₂PO₄]

1.2589 [KH₂PO₄] = 1M - [KH₂PO₄]

2.2589 [KH₂PO₄] = 1M

[KH₂PO₄] = 0.44M

And [K₂HPO₄] = 0.56M

In 800mL = 0.8L:

0.8L * (0.56mol / L) = 0.448 moles K₂HPO₄. The mass is -Molar mass K₂HPO₄: 174.2g/mol-:

0.448 moles * (174.2g / mol) =

78.04g of 0.448 moles must be added
