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:

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.

What is a function of the backbone in animals?
A. It protects against predators.
B. It regulates blood glucose.
C. It surround the spinal cord.
D. It limits movement.

Answers

Answer:

C - It surrounds the spinal cord.

Explanation:

Option A would be incorrect. Having a protective shell on an animal’s back would be one of the ways they would be protected against predators. And having a backbone wouldn’t really make a good shield against predators.

Option B is incorrect. The pancreas regulates blood glucose, not the backbone.

Option D would also be incorrect. It doesn’t limit movement unless it’s bent or positioned abnormally. Or unless it’s broken or malfunctioned.

The only option that is correct is option C. Hope it helps. ^^

ASAP please will mark as brainlist don’t got much time

Answers

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)

= 40835.84J

Answer:

Radiant energy to chemical energy

Explanation:

Got it right on edge 2021

One energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

What is energy transformation?

Energy transformation is the process in which one form of energy converted into another form of energy.

What is photosynthesis process?

Photosynthesis process is defined as the process in which plants makes their own food by using the carbon dioxide, water and sunlight in the chlorophyll.

The balanced chemical equation of photosynthesis process is

6CO2 + 6H2O → C6H12O6 + 6O2.

Since, it have 6 atoms of carbon, 12 atoms of hydrogen and 18 atoms of oxygen on both side. So, it is balanced.

Since, sunlight which it take is in the form of radiant and convert it into chemical energy.

Thus, we concluded that the energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

(10 Points)

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

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

Explanation:
One must first balance the metals before balancing non-metals such as Oxygen and Hydrogen (Hydrogen isn't involved in this case).
So therefore on the right hand side you see 2 Aluminium atoms and thus one must add a 2 before the Aluminium on the left hand side.
Secondly the Iron must be balanced, on the left it can be seen that there are 2 Iron atoms in

and thus a 2 must be added on the right hand side in order for them to balance.
Lastly the Oxygens must be balanced but in this case they already are at 3 on each side and thus the whole equation is now balanced.
