Herz is a measurement for how many cycles of the wave occur per second, which in this case is 261. the period is the time it takes to complete 1 cycle, so if 261 cycles occur per second, one cycle occurs every 1/261 seconds
<span>Correct Answer: D) 6CO2 + 6H20 → C6H12O6 + 6O2</span>
The reactants are Carbon Dioxide (CO2) and Water (H2O) and the products are Glucose (C6H12O6) and Oxygen gas (O2).
In a balanced chemical equation, the number of atoms of each element are same on both left and right hand side of the equation.
In the given options, option D gives the balanced chemical equation and mentions the reactants and products on correct sides of the equation. So the correct answer is Option D
Answer:a) Water is relatively resistant to an increase in temperature
