Molar mass CO2 = 12 + 16 x 2 => 44.0 g/mol
1 mol ----------- 44.0 g
2.1 mol --------- ( mass CO2)
mass CO2 = 2.1 x 44.0 / 1
mass CO2 = 92.4 / 1
= 92.4 g of CO2
hope this helps!
Answer:
c. −1.22 × 10^4 K
Explanation:
Generally, the slope of an Arrhenius plot can be determined either from the graph of In k against 1/T or the available experimental data of the rate constant (k) and the absolute temperature. Mathematically,
Where:
L/(mol.s)
L/(mol.s)
K
K
slope = (ln 2.9*10^-1 - ln 6.6*10^-4)/(1/500 - 1/400)
slope = (-1.238+7.323)/(0.002-0.0025)
slope = 6.085/-0.0005 = -1.22*10^4 K
Explanation:
Reliability can be improved by completing each temperature more than once and calculating an average.
VESPR (<span>Valence Shell Electron Pair Repulsion) is used to determine the shape of the molecules based on their number of electron pairs and how they interact with each other via repulsion. Different numver of electron pairs will form different shapes, e.g. 0 pairs = linear, 1 = pyramidal...</span>
Answer:
The growth of the plant
Explanation:
The growth of the plant from the bean soil is the dependent variable I believe. This is because it could change depending on many factors for e.g. the amount of light or water
