Answer: sunlight, water, air, habitat, and food.
Explanation: All living organisms rely on five fundamental necessities for survival: sunlight, water, air, habitat, and food.
Answer:
The specific heat value for silver is 0.236 J/g-C.
Explanation:
Silver has a mass of 25 grams.
The temperature shifts from 31.5° C to 58.7° C.
The required heat is equivalent to 25 g.
To determine silver's specific heat, the following equation applies:
Where c represents the specific heat of silver.
Thus, the specific heat of silver is 0.236 J/g-C.
Answer: The energies of infrared photons are comparable to those linked with various vibrational states of chemical bonds. Molecules can absorb infrared photons of specific wavelengths, highlighting the types and strengths of different chemical bonds present within the molecules.
Explanation:
Infrared spectroscopy evaluates the vibrational energy states found in molecules. When a molecule absorbs infrared photons, the chemical bonds vibrate at distinct frequencies. Scrutinizing the alterations in vibrational energy within a molecule allows for the identification of different bond types and consequently the molecule’s general structure. The vibrational behaviors of a molecule encompass bending, stretching, and scissoring motions.
2NaOH + H₂SO₄ = Na₂SO₄ + 2H₂O
v(H₂SO₄)=0.25 L
c(H₂SO₄)=2.00 mol/L
v(NaOH)=2.00 L
n(H₂SO₄)=c(H₂SO₄)v(H₂SO₄)
n(NaOH)=2n(H₂SO₄)=2c(H₂SO₄)v(H₂SO₄)
c(NaOH)=n(NaOH)/v(NaOH)=2c(H₂SO₄)v(H₂SO₄)/v(NaOH)
c(NaOH)=2*2.00*0.25/2.00=0.5 mol/L
the concentration of the NaOH solution is 0.5 mol/L
Answer:
This indicates that the enzyme is a type of protein.
Explanation:
It is important to remember that proteins are composed of vast numbers of amino acids. Because these amino acids are tiny units, they cannot function as a catalyst on their own.
However, when they form a polymer, the protein enzyme will possess varying shapes, sizes, and both physical and chemical attributes differing from a single monomer.
Additionally, for proteins to function actively, a specific number of amino acids must combine to create a distinct shape suited to interact with another molecule, thus accelerating the chemical reaction and functioning as an enzyme.
