Choose the larger atom from each pair, if possible.
a. Sn or Si,
b. Br or Ga,
c. Sn or Bi,
d. Se or Sn
Answers
Answer:
a. Sn or Si ⇒ Sn
b. Br or Ga ⇒ Ga
c. Sn or Bi ⇒ similar in size
d. Se or Sn ⇒ Sn
Explanation:
The larger atom has a larger atomic radius. We have to consider how varies the atomic radius for chemical elements in the Periodic Table. In a group (column), the atomic radius increases from top to bottom while in a period (file), it increases from right to left.
a. Sn or Si ⇒ Sn
They are in the same group. Sn is on the top, so it has a larger atomic radius.
b. Br or Ga ⇒ Ga
They are in the same period. Ga is located at the left so it has a larger atomic radius.
c. Sn or Bi ⇒ similar
They are not in the same group neither the same period. Bi is located more at the bottom, so it would be larger than Sn, but Bi is also at the right side, so it would be smaller than Bi. Thus, they have comparable sizes.
d. Se or Sn⇒ Sn
They are not in the same group neither the same period. Se is located at the top and right side compared to Sn, so Sn is the larger atom.

Calcium hydroxide, Ca(OH)2, is an ionic compound with a solubility product constant, Ksp, of 6.5×10–6. Calculate the solubility of this compound in pure water.
Answers
Answer: The solubility of this compound in pure water is 0.012 M
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as [tex]K_{sp}[/tex]
The equation for the ionization of the is given as:
[tex]Ca(OH)_2\rightarrow Ca^{2+}+2OH^-[/tex]
By stoichiometry of the reaction:
1 mole of [tex]Ca(OH)_2[/tex] gives 1 mole of [tex]Ca^{2+}[/tex] and 2 mole of [tex]OH^-[/tex]
When the solubility of [tex]Ca(OH)_2[/tex] is S moles/liter, then the solubility of [tex]Ca^{2+}[/tex] will be S moles\liter and solubility of [tex]OH^-[/tex] will be 2S moles/liter.
[tex]K_{sp}=[Ca^{2+}][OH^{-}]^2[/tex]
[tex]6.5\times 10^{-6}=[S][2S]^2[/tex]
[tex]S=0.012M[/tex]
Thus solubility of this compound in pure water is 0.012 M

How much energy is released when 6.0 g of water is condensed from water to vapor?
Answers
Answer:6.0g x 1 mol/18.02g x 40,65 kJ/mol
Explanation: just did the quiz
13.6 kilojoules (kJ) of energy is released when 6.0 g of water is condensed from water to vapor.
To calculate the energy released when 6.0 grams of water is condensed from water to vapor, we need to use the concept of heat of vaporization (also known as enthalpy of vaporization). The heat of vaporization is the amount of energy required to change one gram of a liquid into vapor at its boiling point, without any change in temperature.
The heat of vaporization of water is approximately 40.7 kJ/mol at its boiling point (100°C or 373.15 K). We can use this information to calculate the energy released when 6.0 grams of water is condensed.
Step 1: Calculate the number of moles of water (H₂O) in 6.0 grams.
Molar mass of water (H₂O) = 2 g/mol (for hydrogen) + 16 g/mol (for oxygen) = 18 g/mol
Number of moles of water = Mass of water / Molar mass of water
Number of moles of water = 6.0 g / 18 g/mol = 0.333 moles
Step 2: Calculate the energy released during condensation.
Energy released = Number of moles of water × Heat of vaporization
Energy released = 0.333 moles × 40.7 kJ/mol = 13.6 kJ
Therefore, approximately 13.6 kilojoules (kJ) of energy are released when 6.0 grams of water is condensed from water to vapor.

How can a chemical reaction be sped up? Select from the drop-down menu to correctly complete the statement. Add a Choose... that is unaffected by a reaction. the choices are, A: catalyst B: coefficient C: product
Answers
Answer:
A: catalyst
Explanation:
In Chemistry, the rate of reaction of chemical elements (reactants) can be sped to produce a chemical compound or elements (products), through the addition of a catalyst that is unaffected by the reaction.
This ultimately implies that, to speed up a chemical reaction, add a catalyst that is unaffected by a reaction.
For example, an enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Generally, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

This is so you can create ratios between each compound in the reaction, and identify the limiting and excess reactants to determine exactly how much can be produced?
The coefficients or molecular quantity of each compound in the balanced equation represents the amount of moles.

A car with a mass of 3,500lbs accelerates negatively from 35m/s to 8m/s in 8s. What is the
car's negative acceleration?
Answers
Answer:
[tex]a=-3.37\ m/s^2[/tex]
Explanation:
Given that,
A car accelerates negatively from 35m/s to 8m/s in 8s.
We need to find the car's acceleration.
Initial speed, u = 35 m/s
Final speed, v = 8 m/s
Time, t = 8 s
The acceleration of an object is equal to the rate of change of velocity. So,
[tex]a=\dfrac{v-u}{t}[/tex]
Put all the values,
[tex]a=\dfrac{8-35}{8}\\\\a=-3.37\ m/s^2[/tex]
So, the acceleration of the car is equal to [tex]-3.37\ m/s^2[/tex].
