8 0

Answer:

Appearing disoriented, such as swimming upside down.

Leaving food uneaten.

White spots on fins or body.

Discolored gills.

Explanation:

Gold Fish are unable to regulate their body temperature, so they are influenced by the temperature around them. If the water is warm, gold fish metabolism accelerates, feeding and respiration increases, and there is a general increase in movement. If the water is cooler, fish become lethargic and tend to be inactive.

A. 6.25moles

B. 0.78moles

C. 0.32moles

D. 0.15moles

E. 0.43moles

Explanation:

use

  • n = mass/molar mass

A. He

  • 25/4 = 6.25moles

B. O2

  • 25/32 = 0.78moles

C. Al(OH)3

  • 27+ 3(17) = 78
  • 25/78 = 0.32 moles

D. GaS3

  • 70+3(32) = 166
  • 25/166 = 0.15moles

E. C4H10

  • 4(12)+10(1) =58
  • 25/58 = 0.43moles

A ball is thrown in the air. The ball goes up, then changes direction and falls down. Why does the ball fall down?
Delicious77 [7]

So the acceleration has actually slowed down the ball because it was going in the direction opposite the velocity. Now see what happens as the ball falls back down to Earth. The ball has zero velocity, but the acceleration due to gravity accelerates the ball downward at a rate of –9.8 m/s2.

hope it helps

Describe the protons, electrons, and neutrons of an atom of hydrogen-2.
AlladinOne [14]

Answer:

However, various hydrogen isotopes, such as H-2, have one proton and one neutron; H-3 has one proton and two neutrons, etc. The sum of the protons and neutrons in an atom's nucleus is its atomic mass. Thus, the atomic mass of the H-2 isotope is two, the atomic mass of the H-3 isotope is three, and so forth.
