First let's look at the photosynthesis equation:
6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
We know that:
CO₂ is carbon dioxide
H₂O is water
<span>C₆H₁₂O₆ is glucose
</span><span>O₂ is oxygen
</span>
We also know that the left side of the reaction is the reactants (which gets used up), and the right side is what is produced.
Now, we can look at each of the choices to see which one matches the equation:
We can eliminate the last two choices automatically because there is no hydrogen atoms present on either side.
The second one is not correct because oxygen is a product, not a reactant.
Therefore, the answer is the first one because carbon dioxide is a reactant, and oxygen is a product.
One Ba2+ and two Br- ions will be there.

Answer: D
Explanation:
London forces become stronger as the atom in question becomes larger, and to a smaller degree for large molecules. [4] This is due to the increased polarizability of molecules with larger, more dispersed electron clouds. The polarizability is a measure of ease with which electrons can be redistributed; a large polarizability implies that the electrons are more easily redistributed. This trend is exemplified by the halogens (from smallest to largest: F 2 , Cl2 , Br 2 , I 2 ). The same increase of dispersive attraction occurs within and between organic molecules in the order RF<RCL<RBr<RI, or with other more polarizable heteroatoms. [5] Fluorine and chlorine are
gases at room temperature, bromine is a liquid, and iodine is a solid. The London forces are thought to be arise from the motion of electrons.
Answer:
B. Infrared.
Explanation:
Referring to the electromagnetic spectrum, ultraviolet rays can be measured with a frequency of 10‐⁸, infrared has a frequency of 10‐⁵, visible radiation has a frequency of 0.5 x 10‐⁶ meanwhile X-rays show a frequency of 10‐¹⁰.
Hence, the largest magnitude among the rest goes to infrared rays, which makes B the correct answer.
