Use the nuclear decay reaction in the picture to answer the following question.
allsm [11]

Answer:

1a. Both sides of the decay reaction have the same charge.

b. The number of nucleons on both sides are the same.

2. The binding energy of one mole of the atom is 17.172 × 10^{16} J.

Explanation:

1a. Considering the two sides of the decay reaction and with respect to the law of conservation of charge, it can be observed that both sides have the same charge. Charge can not be created or destroyed in the process.

b. The number of nucleons on both sides are equal. No nucleon is created or destroyed in the process.

2. Binding energy is the minimum energy required to separate an atom into its nucleons. From Einstein's energy equation;

             E = Δmc^{2}

Where E is the binding energy of the atom, Δm is the mass defect and c is the speed of light.

Given that: Δm = 1.908 g/mol and c = 3 × 10^{8}. So that:

           E = 1.908 × (3*10^{8}) ^{2}

              = 1.908 × 9 × 10^{16}

              = 17.172 × 10^{16} J

The binding energy of one mole of the atom is 17.172 × 10^{16} J.

Using the graphic provided,idenify the reactants of photosynthesis?
Y_Kistochka [10]

Answer:

water, carbon dioxide reacted in the presence of sun light and chlorophyll and form glucose and oxygen.

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water so, the mass of water will be,

The glucose is converted into pyruvate and prod
