Answer:
They all have a hydrogen written separatly towards the beginning of the formula.
Explanation:
If you look at the Arrhenius acid formulas, you can see they all contain a hydrogen (H) at the beginning of them.

4.) Heat is transferred through a piece of metal by _____.
conduction
Conduction happens when both items are in close contact. In a piece of metal. In this case, the heat transfers gradually into the other ends of the object. This makes the transfer rate is slow on a long object with a low surface area.
5.) Heat from the sun travels to earth by _____.
radiation
</span>Sun energy comes from a reaction that will produce a light and heat and it is transferred to the earth by radiation. While conduction and convection need contact with the object, radiation doesn't. Radiation can travels a very long distance, that is why the heat could be delivered to the earth.
<span>
6.) Energy in a vacuum travels by ___.
radiation
</span>One of the examples for energy travels in a vacuum would be sunlight. Sun and earth are separated by vacuum space which means there is no direct contact between earth and sun. That means conduction and convection are not possible.

7.) In a convection current _____.
</span><span>C.)cool fluid is more dense, and therefore, sinks
</span><span>
Cool fluid have lower volume, thus become denser than warm fluid. Since its density higher than the warm fluid, it will sinks and moves toward the earth. The warm fluid also rises to replace the cool fluid.
8.) Nuclear reactions occurring in the Sun _____. Select all that apply.
generate light
generate heat
fuse atoms of hydrogen to make helium atoms
Sun is bright and hot, which means it produces light and heat. The reaction should be producing energy, not absorbing energy. The reaction that produces that energy would be the fusion reaction of hydrogen into helium.
9.) Which of the following statements is true?
</span><span>C.)The sun's energy comes from the nuclear reactions of changing hydrogen into helium.
</span><span>The sun reaction is right, it is forming helium using hydrogens.
Transfer of heat in liquid mostly happens because convection which need direct contact. But the heat can transfer by radiation too, so its a bit ambiguous.
Temperature represents the average kinetic energy of the molecule and it is different with heat/thermal energy.</span>
If you were to make coyote population bigger it would first affect the rabbits because with there being more coyote's they have to bring more food for the pack and with the rabbits being hunted more and more the grass that the rabbits would eat, is not being eaten then the grass will grow more often and more longer.
That is the circle of life in the wild.
Answer:
When we stand on the floor, we apply a force on the floor surface in the downward direction and in return the floor also exerts an upward and equal force on us.
Explanation:
Newton' third law is vey famous and it states that for each and every action, there applies an equal but opposite reaction. Thus the action force and the reaction force always acts on pairs. But they does not contribute to the motion of the object.
One such example that illustrates the action and reaction force from Newton's law is when we stand on the floor we exert a force on the floor surface in downward direction. The floor surface also exerts an opposite and equal force on us in the upward direction.
There are 3, fructose, gluctose, and galactose
