Answer:
The volume will decrease. (option A)
The new volume will be 523 mL (option B)
Explanation:
Step 1: Data given
p1v1/t1 = p2v2/t2
A gas sample occupies 650 mL at 525 mm Hg. What would happen to the volume at 652 mm Hg?
Data given:
650 mL = 0.650 L
525 mm Hg = 525/760 = 0.69079 atm
652 mm Hg = 652 / 760 = 0.857895 atm
Calculate the new volume:
p1*V1 = p2*V2
⇒with V1 = the initial volume = 0.650 L
⇒with p1 = the initial pressure = 0.69079 atm
⇒with p2 = the final pressure = 0.857895 atm
⇒with V2 = The final volume = TO BE DETERMINED
V2 = (p1*V1)/p2
V2 = (0.69079 * 0.650) / 0.857895
V2 = 0.523 L = 523 mL
The volume will decrease. The new volume will be 523 mL
Answer:
Group 7
Explanation:
The element with the electronic configuration 1s2 2s2 2p5 belongs to group 7 of the periodic table because it has 7 electrons in its outermost shell.
Since it has 7 electrons in its outermost shell, the element would need 1 electron to satisfy the octet rule during bond formation.
Answer:
The concentration is ion dependent
Explanation:
The concentration is dependent on the amount of the ions in the solution. This is the rate-determination factor. For a reaction to precipitate, there should be enough ions in the solution. In addition, the Ksp plays an important factor in the reaction. This happens when the amount of ions formed is derived from a strong ionic solution. This then drives the reaction forward.
Here we have to choose the property of the liquid, among the given, which the engineer should primary look to use as the fluid of the engine.
The engineer should primarily looked the liquid which have B. low specific heat capacity.
The Specific heat capacity of a substance is equivalent to the heat needed to increase 1⁰ temperature of the unit mass of the substance. Now if the specific heat capacity of the liquid is low then it will need very little amount of energy to transfer the heat.
A. The low thermal conductivity will cause more time to exchange the energy. Which is not required for the engine.
C. There is no relation between the reactivity of the liquid with the use of the same in the engine.
D. The internal energy will also not affect the rate of the cooling or heating of the liquid.
E. The high density also cannot affect the low rate of exchange energy.
Answer:
Explanation:
Mass of one tablet = 20 mg
Mass of two tablets = 
Percent that is soluble in water = 40%
Mass of tablet that is soluble in water = 
So, mass of solute is 
Density of water = 1 kg/L
Volume of water = 1 L
So, mass of 1 L of water is 
PPM is given by
Hence, the concentration of iodine in the treated water .
