The answer is B. Fusion occurs inside the sun. It creates light and heart that sustain life on earth.

The Sun creates its own energy through fusion. This also happens in larger stars as well.

Have a good day! =)

Answer:

B. Fusion occurs inside the sun. It creates light and heart that sustain life on earth.

Explanation:

We have some phrases about fusion. Firstly, it is necessary to define this phenomenon.

Fusion means "a merging of separate elements into a unified whole". Fusion takes place when two low-mass isotopes, typically for example Hydrogen, under conditions of extreme pressure and temperature. This phenomenon is which powers the sun. Inside the sun, different Hydrogen isotopes such as Tritium and Deuterium unite under extreme conditions to produce a neutron and helium. After the fusion process, a huge amount of energy is released, this energy is much greater than the fission process.

Finally, we can conclude that the answer is: B. Fusion occurs inside the sun. It creates light and heart that sustain life on earth.

Irina18 [472]

Answer:

The diagram provided shows K2O, or potassium oxide.

Explanation:

Ok... so, there are two "K2O" options, so I would just choose either and hope for the best. I don't know, maybe it's a mistake...

When the following equation is balanced, what is the coefficient for CaCl2 ?

USPshnik [31]

To know if an equation is balanced you need to check and see how much of each molecule is on either side of the arrow. Right now you have 1-Ca, 2-H, 2-Cl on the left side of the arrow and 1-Ca, 2-Cl, and 2-H on the right side too. Because all the molecules are equal on both sides this means that the equation is balanced. So in front of the CaCl2 there is an assumed coefficient of 1. The answer is 1.

Answer:

your answer is C

Explanation:

The electron-dot structure of NH3 places one set of nonbonding electrons in the valence shell of the nitrogen atom. that means there are three bonded atoms and one single pair for a coordination number of four surrounding the nitrogen, the same occurs in water to. along with the Lewis dot structure for ammonia, NH3. the non bonding atoms are basically like hydrogen atoms the try to refuse to bond and they can't be fused unless the right conditions are met.

For the reaction 2Co3+(aq)+2Cl−(aq)→2Co2+(aq)+Cl2(g). E∘=0.483 V what is the cell potential at 25 ∘C if the concentrations are [

Nesterboy [21]

Answer:

Ecel =0,04 V

Explanation:

Apply the Nerst equation,

Ecel= Ecelº - (RT/nF)*lnQ

where R=8,314 J/molK, T=25ºC=298K and F =96 485 Coulombs/mol e- and n=number of moles of electrons transferred in the balanced equation. Q is cocient of products and reactives power to respective coefficients, if is a gas apply partial pressure

Write the semiequation redox and verify the numbers of electron for balance. In this case you don't need to change nothing

2Cl−(aq)→Cl2(g) + 2e-

2CO3+(aq) + 2e-→2CO2+(aq)

2Cl−(aq) + 2CO3+(aq) →2CO2+(aq) + Cl2(g)

Hence

Ecel= 0.483 V - 0.013Ln ([CO2+]^2*PCl2] / [CO3+]^2*[Cl-]^2)

Ecel= 0.483 V - 0.013Ln ([0.205]^2 * 7.3] / [0.19]^2*[0.144]^2)

Ecel =0,04 V

A substance that has a uniform composition and is able to be separated by physical means is?

lapo4ka [179]

The answer is homogeneous mixture. It is a mixture which has uniform composition and properties all throughout. Mixtures can be separated by physical processes. Mixtures are systems that consist of two or more substances which are mixed but not chemically combined.
