How does changing the amount of one substance affect a mixtures identity and a compounds identity iscience?
pychu [463]

Explanation:

A compound is defined as follows.

  • Compounds are pure substance.
  • The atoms bonded in a compound are in specific proportion.
  • A compound is formed by chemical combination.
  • For a compound, melting point and boiling point is defined.

A mixture is defined as follows.

  • Mixtures are impure substance.
  • The bonded atoms in a mixture are in any proportion.
  • A mixture is formed by physical combination.
  • For a mixture, melting point and boiling point is not defined.

On changing the amount of one substance will affect the formation of compound as a compound requires atoms to be bonded in a specific proportion. Whereas changing the amount of one substance will not affect the formation of mixtures  as atoms can be bonded in any proportion in a mixture.

If an element has an atomic number of 8 and an atomic mass number of 18, would it be an isotope? Why or why not?
hoa [83]

Answer:

It would be an isotope.

Background Information:

Isotopes are typically elements that have a different number of protons than neutrons. The atomic mass is the total number of protons and neutrons. The atomic number is the number of protons.

Explanation:

If the atomic number is the number of protons that means that this particular element has 8 protons. If the atomic mass is the total number of protons and neutrons then we can simply take away the amount of protons from that number, 18 - 8 = 10. If we take protons away from the number of protons and neutrons we are left with the number of neutrons. So there are 10 neutrons. Because there are 8 protons and 10 neutrons, or a different amount of neutrons and protons we know that this particular atom is an isotope.

Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound
Alecsey [184]

Answer:

4.5 × 10^14 Hz

Explanation:

According to this question, chlorophyll pigment strongly absorbs light with a wavelength of 662nm. To calculate the frequency of this light, the following formula is used:

λ = v/f

Where;

λ = wavelength (m)

v = speed of light (3×10^8m/s)

f = frequency of light (Hz)

Since the λ = 662nm = 662 × 10^-9m,

f = v/λ

f = 3 × 10^8/662 × 10^-9

f = 0.004531 × 10^(8+9)

f = 0.0045 × 10^17

f = 4.5 × 10^14 Hz
