Natural sources include decomposition,ocean release and respiration.
Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal,oil and natural gas.
D.
A parent with type A B blood can ever have a child child with type O blood.
Explanation:
An offspring gets an allele for blood type from every parent. Therefore unless both parents have blood type O the offspring cannot have blood type O.
A person with blood group O means they do not blood group antigen on their red blood cells. They cannot pass the antigens to their offspring. A person with AB means they have both antigens for A & B blood groups and can pass either to any of the offspring they have.
The passing down of the blood group alleles follow the Mendelian principles of independent assortment.
Answer:
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom

Answer:
Rate = 43 M⁻¹s⁻¹[NO₂][O₃]
Explanation:
We need to find the reaction order in
rate = (NO₂ )ᵃ (O₃ )ᵇ
given:
( NO₂ ) M ( O₃ ) M Rate M/s
0.10 0.33 1.420 (1)
0.10 0.66 2.840 (2)
0.25 0.66 7.10 (3)
When keeping the NO₂ concentration constant in the first two while doubling the concentration of O₃ , the rate doubles. Therefore it is first order with respect to O₃
Comparing (2) and (3) increasing the concentration of NO₂ by a factor of 2.5 and keeping O₃ constant , increased the rate by a factor of 2.5. Therefore the rate is first order with respect to NO₂
Then rate law is
= k (NO₂) (O₃ )
To find k take any of the three and substitute the values to find k:
1.420 M/s = k (0.10)M x (0.33)M ⇒ k = 43 /Ms
Then the answer is Rate = 43 M⁻¹s⁻¹[NO₂][O₃]
