Answer:
Its reliability is confirmed by many scientists
Explanation:
The science and the pseudoscience have multiple differences that separate them clearly and sharply. The science, doesn't matter about scientific field we are talking about, is confirmed by numerous scientists. In order for something to be accepted in the scientific circles as a science, the particular thing in question undergoes numerous studies, from numerous different scientists or scientific groups. If all of the results of all of the studies are confirming the same thing, that it can be accepted as science.
A. The reactants are located to the left of the arrow in the chemical equation
Answer:
Volume of NaOH reacted = 1.6 L
Explanation:
<u>Given:</u>
Molarity of H2SO4, M1 = 4.0 M
Volume of H2SO4, V1 = 0.6 L
Molarity of NaOH, M2 = 3.0 M
<u>To determine:</u>
Volume of NaOH,V2
<u>Explanation:</u>
The given neutralization reaction is:
Here 2 moles of NaOH reacts with 1 mole of H2SO4
i.e. moles of NaOH = 2(moles of H2SO4)
Since:
Answer:Difference between Ceres and Pluto
Nestled in the asteroid belt between Mars and Jupiter, Ceres is a tiny loner, while Pluto — in the Kuiper Belt at the edge of the solar system — is nearly three times as big and hosts a handful of moons. A mixture of rock and water ice dominates Ceres' landscape, while methane and nitrogen ices cover Pluto
Explanation:
Answer:
4g of the radioactive element present
Explanation:
Radioactive elements are atoms that are unstable in normal conditions and are converted in another different atoms.
1 half life express the time that is need to decay the half of the initial amount of the radioactive element.
If initially we have 8g of the radioactive element, after 1 life we will have 8g/2 =
4g of the radioactive element present
