A physical property is any property that is measurable whose value describes a state of a physical system.A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom.The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. A period is the name given to a horizontal row of the periodic table.a group is a column of elements in the periodic table of the chemical elements.

During photosynthesis, photocenters in chlorophyll capture energy from photons to excite electrons. The energized electrons are
marissa [1.9K]

One claim that supports one law of thermodynamics in photosynthesis is that energy is conserved, but the form of energy changes (Law 1).

<h3>What is photosynthesis?</h3>

Photosynthesis is a process done by plants and other organisms to obtain energy. This process implies a set of reactions that aim at converting light energy into chemical energy the organisms can use.

<h3>How is photosynthesis related to thermodynamics?</h3>

One way photosynthesis supports the laws of thermodynamics is through the first law that establishes energy is conserved, but the form of the energy can change.

This is because, in photosynthesis, the initial solar energy is transformed into chemical energy by storing the energy in carbon-hydrogen chemical bonds. This means the form of energy has changed but the energy is preserved.

Note: This question is incomplete because the graph is not given; due to this, I answered it based on general knowledge.

An empty beaker is weighed and found to weigh 23.1 g. Some potassium chloride is then added to the beaker and weighed again. The
GuDViN [60]

Answer:Mass of Potassium chloride =1.762g

Explanation:

Mass of empty beaker = 23.100 g

Mass of beaker with Potassium chloride = 24.862g

Mass of Potassium chloride = Final weight - initial weight = Mass of beaker with Potassium chloride  - Mass of empty beaker = 24.862-23.100 = 1.762g

Which of the following an inorganic compound?
oksano4ka [1.4K]
An organic compound is one which consists of a chain of carbon atoms with other atoms bonded to the chain.

Pentane has 5 carbon atoms with surrounding hydrogens.
glucose is a chain of 6 carbon atoms
butane is similar to pentane

water has no carbon atoms, and the central atom is oxygen ---> therefore it is inorganic!
