Answer:
Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.
Explanation:
Answer:
3,8×10⁻⁵ mol/L of potassium permanganate solution
Explanation:
To calculate concentration in mol/L you must convert the 3,8 umol to moles and 100 mL to liters, knowing 1 umol are 1×10⁻⁶mol and 1L are 1000 mL.
3,8 umol × (1×10⁻⁶mol / 1 umol ) = 3,8×10⁻⁶mol of potassium permanganate.
100 mL × ( 1L / 1000 mL) = 0,100 L
Thus, concentration in mol/L is:
3,8×10⁻⁶mol / 0,100 L = 3,8×10⁻⁵ mol/L of potassium permanganate solution

Answer:
about 327 g of sulfur
Explanation:
Reaction equations.
2S + 2O2 = 2SO2
2SO2 + O2 = 2SO3
2SO3 + 2H2O = 2H2SO4
1.00 kg H2SO4 (1000 g H2SO4 / 1kg H2SO4) x (1 mole H2SO4 / 98.079 g H2SO4) x
(1 mole S / 1 mole H2SO4) x (32.065 g S / 1 mole S)
= 326.93 g S needed to be burned to produce 1.00 kg of H2SO4
Answer:2
Explanation:because the compound is CaI2, Ca needs to lose 2 electrons and I needs to gain 1 electron to reach an octet and so there will be 2 I atoms therefore 2 electron transfer
Explanation: For the given acid-base reaction, The molecular equation is:
Molecular equation:
As we know, is a strong acid, so in the ionic equation, it will completely dissociate into its respective ions.
The ionic equation for the given acid-base reaction is given by:
As nitrate ions are present on both the sides, so in the net ionic equation, it will get cancelled out, then the net ionic equation becomes:
Net ionic equation:
