7th grade science , please don’t get the answer from the internet :(
Liula [17]

Answer:

See the answer below

Explanation:

1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.

2. Cellular respiration can be aerobic or anaerobic.

Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.

        C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP

Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.

       C_6H_1_2O_6 -> 2C_3H_6O_3 + ATP

3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.

During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:

       6CO_2 + 6H_2O --> C_6H_1_2O_6 + 6O_2

During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:

     C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP

Why is an amide less reactive to nucleophilic acyl substitution than an acid chloride?
Olin [163]

An amide is less reactive to nucleophilic acyl substitution than an acid chloride because more electron density is donated to the carbonyl by nitrogen.

<h3>What is electron density?</h3>

In quantum chemistry, electron density, also known as electronic density, is a metric for the likelihood that an electron will be found at a microscopic portion of space surrounding a specific point. The likelihood of finding an electron at a particular position near an atom or molecule is represented by electron density. In general, areas with a high electron density are where the electron is most likely to be located. The attractive forces between the electrons and the nuclei in a molecule are what hold the nuclei together in molecule, hence the electron density is essential to the bonding and geometry of a molecule. The repulsions between the nuclei and the electrons function as an antagonist to these attractive forces.

Write the dissociation of hydrosulfuric acid
Vesnalui [34]

Answer:

Explanation:

Hydrosulfuric acid (H_2S) is considered a 'weak acid." It dissociates in water according to this reaction: H_2 S(aq) + H_2O(t) HS^-(aq) + H_3O^+(aq) k_a = 9 times 10^-8 Hydroiodic acid (HI) is considered a "strong acid".
