The final step in correctly matching ammunition to the fire arm is to MATCH THE INFORMATION ON THE BARREL WITH THE INFORMATION ON THE CARTRIDGE OR THE SHOT SHELL.
Getting the final step right is critical because if this final step is not properly carried out, an explosion can result, which can seriously injure the user and the bystanders or even kill them.
Answer:
Cs > Iron > Aluminum > Carbon > Neon
Explanation:
The most metallic from the given choices is Cesium and the least metallic is Neon.
Neon is noble gas and not a solid.
Metallic character of elements decreases across the period and increases with increasing electronegativity.
The most leftward element is Cesium and will be the most metallic. Neon has the least metallic character since it is a noble gas.
Cesium > Iron > Aluminum > Carbon > Neon
Answer: A. Cilla Is Correct.
Answer:
1.28 M
Explanation:
Step 1: Given data
Mass of luminol (solute): 17.0 g
Volume of water: 75.0 mL (this is also the volume of solution)
Step 2: Calculate the moles corresponding to 17.0 g of luminol
The molar mass of luminol is 177.16 g/mol.
17.0 g × 1 mol/177.16 g = 0.0960 mol
Step 3: Calculate the molarity of the solution
We will use the definition of molarity
M = moles of solute / liters of solution
M = 0.0960 mol / 0.0750 L = 1.28 M
