You need to use Stoichiometry
Answer:
B. During the light reactions of photosynthesis, water is split, removing electrons and protons, and oxygen gas is released.
Explanation:
In Photosynthesis two phases occurs. They are grouped into light dependent and light independent phase (dark phase) reactions. In the light dependent phase, sunlight is trapped by chlorophyll and water is split into its components ( oxygen, hydrogen ions and free electrons; photolysis). Part of the electrons and the hydrogen ions are picked up by NADP (Nicotinamide adenine dinucleotide phosphate) converting it to NADPH and part of the electrons are used to replenished the photosystems trapping the sunlight.
Answer:
Molecular formula = C₄H₆As₆Cu₄O₁₆
Explanation:
Given data:
Empirical formula = C₂H₃As₃Cu₂O₈
Molar mass of compound = 1013 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass of C₂H₃As₃Cu₂O₈ is 506.897 g/mol
by putting values.
n = 1013 / 506.897
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₂H₃As₃Cu₂O₈)
Molecular formula = C₄H₆As₆Cu₄O₁₆
Answer:
.00352mol/L
Explanation:
molarity (concentration) = number of moles / volume of solvent (in L)
M = .99g / 56.108g/mol / .5L
M = .0176mol / .5L
M = .00352mol/L
Answer:
Evaporation wll occur
Explanation:
Boiling point is reached when the vapor pressure equals the atmospheric pressure around. The vapor pressure is the pressure exerted by a gas which is in contact with its own solution or liquid. It increases with increasing temperature.
The atmospheric pressure is the pressure of the atmosphere around. When the vapor pressure exceeds atmospheric pressure, boiling point is reached and surpassed. At this point, evaporation will occur.
