<h2>Endothermic and Exothermic</h2>

Explanation:

  • An exothermic response discharges heat and endothermic absorbs to heat
  • The whole of the enthalpies of the reactants is more prominent than the product, the response will be exothermic
  • In the product that the items side has a bigger enthalpy, the reaction is endothermic
  • An exothermic method  is one that emits heat. This heat is transferred to the environment
  • An endothermic reactions is one in which heat must be provided to the system from the environment

Nuclear energy can be used to power _______. a. street lights b. businesses c. homes d. all of the above Please select the best
Taya2010 [7]
<h3><u>Answer;</u></h3>

All the above

-street lights

-businesses

- Homes, etc

<h3><u>Explanation; </u></h3>
  • Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
  • Nuclear reactions are used to release nuclear energy that generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.
  • Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
  • Nuclear energy may be used in a wide variety of fields as it generates high levels of electricity without causing damage to our environment and atmosphere.

How does atomic radius change from top to bottom in a group in the periodic table?
suter [353]
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.

In the investigation "Comparing the Effects of the Products of Cellular Respiration
Marianna [84]

The solution changed color because the substances are not neutral.

<h3>pH</h3>

Chemical substances have different concentrations of the hydrogen cation, called PH.

The higher the pH, the more basic the substance, and the lower the more acidic.

Bromothymol blue is a pH indicator that changes its color according to the pH of the substance, yellow for acid, blue for basic and green for neutral.

In the case of the reactions in question, we have the release of CO2 (acid) in combustion and in cellular respiration, changing the color of bromothymol blue to yellow.
