The answer that best completes the statement above is EXTENSIVE LAVA FLOW. Maria is the name that refers to an asteroid family. And this has punctured the surface of the moon which created magma to bleed out and resulted in an extensive lava flow. Hope this answer helps.

The discovery of the atomic nucleus, or perhaps better stated the development of theory of the nucleus, is credited to Ernest Ru
Greeley [361]

Answer:

Both of the studies said that the mass of the atom is centered in the nucleus, which is positive, and there are electrons (negative particles) orbiting it. So, Rutheford and Nagaoka discovered that the atom can be divisible and it has an empty space.

But, in the model of Nagaoka, the nucleus was huge, and for Rutherford, the nucleus was really small, and the mass was concentrated. By his experiment with the gold sheets, the theory was appropriated. That's why Rutherford is credited with the discovery of the nucleus. Nagaoka was incorrect in his suppositions.

A mixture of chalk powder and water can be
grin007 [14]

Answer:

<h3>Right answer is: ( a) chalk powder remains suspended in water.</h3>

Explanation:

Filtration is the technique used to separate suspended solute particles from a solution . The chalk powder remains suspended in the solution and can easily be filtered through a filter paper , the chalk powder can be collected on the filter paper and clear solvent is collected as the filtrate.

Consider the half reaction below.
Radda [10]
Answer: the second option: <span>Iron is being oxidized
</span>

Explanation:

1) Oxidation is the increase of the oxidation state (number) due to the loss of electrons.

2) In the given reaction, you can see that in the left side the atom is Fe. 

When an element (atom) is not combined (or combined with it self) its oxidation state is 0. 

3) In the right side of the given equation you that iron is now in form of cation with charge 2+: Fe²⁺.

That means that the new oxidation state of the element is 2+.

4) This change in the oxidation state, of course, is accompanied by the loss of the two electrons: 2e⁻.

5) Conclusion: the iron has oxidized by losing two electrons and increasing its oxidation state from 0 to 2+.

The daily production of carbon dioxide from an 880 MW coal-fired power plant is estimated to be 31,000 tons. A proposal has been
miskamm [114]

Answer:

1.3578\times 10^{8} m^3 volume of carbon dioxide gas would be collected during a one-year period.

Explanation:

Mass of carbon dioxide gas collected in a day = 31,000 Tonn

1 Tonn = 1000 kilogram

31,000 Tonn = 31,000\times 1000 kg=31,000,000 kg

Specific volume of the carbon dioxide gas = V_s

V_s=0.012 m^3/kg

Volume of carbon dioxide gas collected in a day = V

V=V_s\times 31,000,000 kg=0.012 m^3/kg\times 31,000,000

V=372,000 m^3

1 year = 365 days

Volume of carbon dioxide gas collected in a year = V'

V'=372,000\times 365 m^3=1.3578\times 10^{8} m^3

1.3578\times 10^{8} m^3 volume of carbon dioxide gas would be collected during a one-year period.

A chemical reaction resulting in the transfer of electrons or hydrogen atoms from one molecule to another is called a(n) _______
anzhelika [568]

The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.

In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.

In other words, oxidation is defined as:

  • Loss of electrons
  • Loss of hydrogen atoms
  • Gain of oxygen atoms
  • Gain in oxidation number

While reduction is defined as:

  • Gain of electrons
  • Gain of hydrogen atom
  • Loss of oxygen atom
  • Reduction in oxidation number
