The correct option is: VAPORIZATION AND CONDENSATION.
Matters have the ability to change from one state to another state, this is called state transition. In the question given above, the carbon dioxide, which Uyen's was breathing out came in form of vapors and forms a cloud by condensing. Condensation is the process by which water droplets are formed when a vapor from comes in contact with cold surfaces. In the question given above, the vaporized gas condenses when it comes in contact with the humid air.
Answer:
391.462 g
Explanation:
First, let's calculate the total mass of the solution by the definition of density (d)
d = m/V, where <em>m</em> is the mass in gram and <em>V</em> the volume in mL. So for the given solution
1.285 = m/800
m = 1028 g
The mass of sulfuric acid will be:
0.3808x1028 = 391.462 g
Answer:
Inventory management documentation
Explanation:
Inventory management documentation is a system of tracking the company's stock. In ordinary terms, Inventory management refers to the sequential processes which include; ordering, storing, and using a company's inventory. The scope of inventory management also covers the management of raw materials, components, and finished products as well as warehousing and processing such items.
Inventory management documentation will surely aid Lin to know what employee has received his/her laptop and who has not from his inventory records. The scope of Inventory management documentation transverses the entire spectrum of a supply chain.
Answer:
It take 3.5 *10² min
Explanation:
Step 1: Data given
Mass of the nickel = 29.6 grams
4.7A
Step 2: The balanced equation
Ni2+ (aq- +2e- → Ni(s)
Step 3: Calculate time
W = (ItA)/(n*F)
⇒ W = weight of plated metal in grams = 29.6
⇒ I = current in coulombs per second.
= 4.7
⇒ t = time in seconds.
⇒ A = atomic weight of the metal in grams per mole. = 58.69
⇒ n = valence of dissolved metal in solution in equivalents per mole. = 2
⇒ F = Faraday's constant in coulombs per equivalent. F = 96,485.309 coulombs/equivalent.
29.6 = (4.7 * t * 58.69)/(2*96485309)
t = 20707 seconds
t =345 minutes = 3.5 * 10² min
It take 3.5 *10² min
