Write orbital diagrams (boxes with arrows in them) to represent the electron configurations of carbon before and after sp hybrid

NemiM [27]

Carbon has an electron configuration of 1s^2 2s^2 2p^2. During sp hybridization, one s and one p orbital of carbon combine to form two sp hybrid orbitals.

Calculate the mass (g) of each product formed when 43.82 g of diborane (B₂H₆)

Stoichiometry:

The area of study in chemistry concerned with the quantities of chemical species produced or required for a given chemical reaction is stoichiometry. The stoichiometric coefficients of the balanced chemical equation are often used to relate the amounts of substances to one another.

Evaluation :

The balanced chemical equation for the reaction is given as follows:

$B_{2} H_{6} + 6H_{2} O$ → $2H_{3} BO_{3} + 3H_{2}$

By using the molar mass of the given chemical species, along with the stoichiometric coefficients of the balanced chemical equation, we determine the mass of each product as:

43.82 g $B_{2} H_{6}$ × $\frac{1 Mol B_{2} H_{6} }{27.66 g}$ × $\frac{3molH_{2} }{1 molB_{2}H_{6} }$ × $\frac{2g}{1 mol H_{2} } = 9.51 g H_{2}$

43.82 g $B_{2} H_{6}$ × $\frac{1 mol B_{2} H_{6} }{27.66 g}$ × $\frac{1 mol H_{3}BO_{3} }{1 mol B_{2} H_{6} }$ × $\frac{61.8g}{1 mol H_{3} BO_{3} } = 196 gH_{3} BO_{3}$

Which of the following substances is formed during photosynthesis A.carbon dioxide

myrzilka [38]

The answer is C, Sugar.

An array of chemical reactions done by plants to transform energy from the Sun into chemical energy, that is, in the form of sugar is known as photosynthesis. Primarily, the plants utilize sunlight's energy to react water and carbon dioxide to generate glucose (sugar) and oxygen. In plants, the process of photosynthesis takes place in the chloroplasts.
