H2SO4 is referred to as a strong acid and is denoted as option A.
<h3>What is an Acid?</h3>
This refers to any substance which tastes sour when in water and changes the color of blue litmus paper to red. It is usually very corrosive and are used in industries for different functions.
H2SO4 is referred to as a strong acid because it dissociates completely in its aqueous solution or water.

Answer:
They are called corpuscles
Explanation:
Answer:Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.

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>
Answer:
Electrons- 95
Protons- 95
Neutrons-146
Explanation:
An atoms is made up of three fundamental particles; electrons, protons and neutrons,
Americium belongs to the f block in the periodic table. It is an actinide element.
An atom of Am-241 contains 95 protons, 95 electrons and 146 neutrons.
