Answer:
0.111 mol
Explanation:
We can solve this problem by using<em> Avogadro's law</em>, which states that at constant pressure and temperature:
Where in this case:
We <u>input the data given by the problem</u>:
- 150.0 mL * n₂ = 50.0 mL * 0.332 mol
And <u>solve for n₂</u>:
Answer:
Electron geometry- Tetrahedral
Molecular geometry- Bent
Bond angle- <<109.5°
Explanation:
According to the Valence Shell Electron Pair Repulsion (VSEPR) Theory, the shape of a molecule depends on the number of electron pairs present bon the central atom of the molecule. The electron pairs orient themselves as far apart in space as possible to minimize repulsion between electron pairs.
However, the repulsion between all electron pairs is not the same. Lone pairs cause more repulsion around the central atom than bond pairs. Hence lone pairs tend to distort the molecular structure away from that predicted on the basis of Valence Shell Electron Pair Repulsion Theory.
Considering XY2Z2, there are four electron domains, two bond pairs with bonding groups at 180° apart and two lone pairs. Based on VSEPR theory, a tetrahedral shape is expected with a bond angle of about 109°.
The presence of two lone pairs distorts the observed molecular geometry to a bent shape with bond angle <<109°, hence the answer above.
Answer:
Two plates pull towards each other
Explanation:
Along a convergent plate boundary, two plates moves towards each other as the move in the same direction.
This results in different forms of plate interactions depending on the plate types.
- At an ocean - ocean and continental - ocean convergent front, subduction of the oceanic plate occurs. This is because the oceanic plate below is denser than the asthenosphere.
- At a continental - continental convergent front, the continental crust is pulls upward and build up as a mountain.
- The subduction produces trenches and some volcanic islands.
<u>Answer:</u>
The Calvin cycle converts ATP and NADPH to "convert CO2 to sugar".
<u>Explanation:</u>
When carbon dioxide reaches inside the leaf through pores called stomata in plants and spreads to the chloroplast stroma, it act as the location of Calvin cycle reactions where sugar is naturally produced.The light-independent processes are also called such reactions as they are not primarily guided by light.
The Calvin cycle processes can be separated into three main channels: carbon fixation, reduction, and starting molecule's regeneration as explained below:
- <u>Carbon Fixation:</u> Six-carbon compound are generated in this step that bifurcate into two molecules (three-carbon compound) 3-phosphoglyceric acid (3-PGA), catalyzed by the enzyme rubisco or RuBP carboxylase/oxygenase.
- <u>Reduction: </u> In this phase of the cycle 3-PGA molecules are converted into glyceraldehyde-3-phosphate (G3P) i.e three-carbon sugar by using ATP and NADPH.
- <u>Regeneration:</u> Many G3P molecules are used to generate glucose, while others have to be recycled to recreate the acceptor RuBP.
