<span>It changes with new evidence.

The example shows that science changes with new evidence. Science can not change with common beliefs because first of all beliefs should be proved and become evidence. Second, science is not fixed because of the scientific method and experimentation, which is a phase of the scientific method.

Answer:

B. It changes with evidence. Of course when looking through a microscope at organism they are going to change with new evidence.

I took the test and got it right. Have a great day.

What term best defines the splitting of nuclei into smaller fragments due to the bombardment of neutrons?
Andre45 [30]
Well the knowing what the answer choices mean would be most helpful for this problem:

a.  The definition of "Fusion" in general means bringing things together into one unit. In biology, Fusion sometimes refers to cellular fusion, the bringing of two or more uninuclear (cells with one nucleus) together to form multinuclear cells.
B. Fission is almost the opposite of "fusion" in that it is the action of dividing or splitting into two or more parts. This sounds like fission of a heavy nucleus to me.
c. molecular blending forms polymers. So this choice is incorrect.
d. atomic rebonding- when atoms on different molecules combine to form diatomic ions.

hope this helped!

a 3.81 g sample of NaHCO3 was completely decomposed. After decomposition, Na2CO3 had mass of 2.86g. Determine mass of H2CO3 prod
qaws [65]

Answer:

1.67g H2CO3 are produced

Explanation:

Based on the reaction:

2NaHCO3 → Na2CO3 + H2CO3

<em>2 moles of NaHCO3 produce 1 mole of Na2CO3 and 1 mole of H2CO3</em>

To solve this question we need to find the moles of Na2CO3 = Moles of H2CO3. With their moles we can find the mass of H2CO3 as follows:

<em>Moles Na2CO3 -Molar mass: 105.99g/mol-</em>

2.86g Na2CO3 * (1mol/105.99g) = 0.02698 moles Na2CO3 = Moles H2CO3

<em>Mass H2CO3 -Molar mass: 62.03g/mol-</em>

0.02698 moles  * (62.03g/mol) =

<h3>1.67g H2CO3 are produced</h3>

When an atom makes a transition from a higher energy level to a lower one, a photon is released. What is the wavelength of the p
kykrilka [37]

Answer:

Wavelength of the photon depends on transition from different states.

Explanation:

The wavelength of the photon that is emitted from the atom during the transition depends on the transition from different states. If the photon is emitted from n=4 state to n=3 state, the wavelength of photon is 1875 while on the other hand, if the photon is emitted from n=5 state to n=3 state, the wavelength of photon is 1282. If the photon is emitted from n=3 state to n=2 state, the wavelength of photon is 656.
