Answer:

The essence including its particular subject is outlined in the following portion mostly on clarification.

Explanation:

  • The energy throughout the campfire comes from either the wood's latent chemical energy until it has been burned to steam up and launch up across the campfire. The electricity generation for something like a campfire seems to be in the context including its potential chemical energy which is contained throughout the firewood used only to inflame the situation.
  • The energy output seems to be in the different types of heat energy radiating across the campfire, laser light generated off by the blaze, and perhaps a little number of electrical waves, registered throughout the firewood cracking whilst they combust throughout the blaze.

and,

chemical energy ⇒ heat energy + light energy + sound energy

Which of the following equations represents Photosynthesis? 16CO2 + 6H2O -----> C6H12O6 + 6O22C6H12O6 + 6O2 -----> CO2 + 6
lidiya [134]

Answer:

  • 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Explanation:

<em>Photosynthesis</em> is the chemical process carried out by plants for the conversion of inorganic matter (carbon dioxide and water) into organic matter (glucose) with the release of oxygen, using light (sun energy).

So the chemical process may be represented by:

  • <u>Word equation: </u>

        carbon dioxide + water + sun energy → glucose + oxygen

  • <u>Skeleton equation:</u>

       CO₂ + H₂O + sun energy → C₆H₁₂O₆ + O₂

  • <u>Balanced chemical equation:</u>

       6CO₂ + 6H₂O + sun energy → C₆H₁₂O₆ + 6O₂

  • <u>Supressing the energy to show only the chemical compounds:</u>

        6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Boron has two isotopes, Boron 10 which has a mass of 10.0129 amu and Boron-11 with a mass of 11.0093 amu. B-10 occurs 84.74% of
podryga [215]

The average atomic mass of Boron: 10.431 amu

<h3>Further explanation   </h3>

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.  

So Isotopes are elements that have the same Atomic Number (Proton)  

Atomic mass is the average atomic mass of all its isotopes  

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu  

Mass atom X = mass isotope 1 . % + mass isotope 2.%  + ...

The average atomic mass of boron :

\tt avg~mass=0.8474\times 10.0129+0.1526\times 11.0093\\\\avg~mass=10.431~amu

Heat is being removed from a substance, but its temperature does not change. What is
ololo11 [35]
So its temperature will not rise, since kinetic energy of molecules remains the same. The quantity of heat absorbed or released when a substance changes its physical phase at constant temperature (e g. From solid to liquid at melting point or from liquid to gas at boiling point) is termed as its latent heat.

When should a lab coat, safety goggles, and gloves be worn in the laboratory?
Sever21 [200]
I would say that you should wear a lab coat, safety goggles, and gloves when the teacher says so - not everything in a lab is dangerous, so there is no need to always wear these. But when the teacher says you should - then you should.
