Answer:
Octahedral
Explanation:
Recall that according to Valence Shell Electron Pair Repulsion Theory(VSEPR) the shape of a molecule is based on the number of electron pairs on the outermost shell of its central atom.
In BrF4^-, the bromine atom is surrounded by 6 electron pairs. Four bond pairs and two lone pairs. This means a total of six regions of electron density.
According to VSEPR Theory, BrF4^- has an octahedral electron geometry and its the molecular geometry will be square planar since it is of the type AX4E2.
An image of the BrF4^- is attached below.
Answer:
- Add more zinc hydroxide.
- Increase the temperature.
Explanation:
Hello,
Based on the given chemical reaction at equilibrium:
Thus, by considering the Le Chatelier's principle, increasing the zinc hydroxide solubility, it means favor the direct reaction, could be attained by:
- Adding more zinc hydroxide as the addition of products favor the formation of products.
- As the reaction is endothermic, the energy is considered as a reactant, therefore, increasing the temperature the direct reaction is favored.
Best regards.

Answer:
69.6 g CO₂
Explanation:
To find the mass of carbon dioxide, you need to (1) convert grams LiOH to moles LiOH (via molar mass from periodic table values), then (2) convert moles LiOH to moles CO₂ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units (desired unit in the numerator). The final answer should have 3 sig figs to reflect the given value's sig figs.
Molar Mass (LiOH): 6.9410 g/mol + 15.998 g/mol + 1.008 g/mol
Molar Mass (LiOH): 23.947 g/mol
2 LiOH(s) + 1 CO₂(g) ----> Li₂CO₃(s) + H₂O(l)
Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)
Molar Mass (CO₂): 44.007 g/mol
75.8 g LiOH 1 mole 1 mole CO₂ 44.007 g
------------------ x ---------------- x ----------------------- x ------------------- =
23.947 g 2 moles LiOH 1 mole
= 69.6 g CO₂
