Answer: -
B: it can be flattened and bent
Explanation: -
Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.
Metals are bonded together by metallic bonds.
Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.
Answer:
The molarity of this final solution is 0.167 M
Explanation:
Step 1: Data given
Volume of a 0.100 M HNO3 solution = 50.0 mL
Volume of a 0.200 M HNO3 = 100.0 mL
Step 2: Calculate moles
The final molarity must lie between 0.1M and 0.2M
Moles = molarity * volume
Moles HNO3 in 50mL of a 0.100M solution = 0.05 L *0.100 M = 0.005 mol
Moles HNO3 in 100mL of a 0.200M solution = 0.100 L*0.200 = 0.020mol
total moles = 0.005+0.020 = 0.025 moles in 150mL solution = 0.150L
Step 3: Calculate molarity of final solution
Molarity = mol / volume
Molarity 0.025 moles /0.150 L
Molarity = 0.167M
The molarity of this final solution is 0.167 M
You could identify a physical property of a substance before you performed the activity because the characteristics of a material known as its physical qualities are those that may be investigated independently of the substance's chemical makeup.
This is further explained below.
<h3>What is
physical property?</h3>
Generally, Any attribute that can be measured and has a value that can be used to describe the state of a physical system is considered to be a physical property.
In conclusion, The changes that take place in a system's physical attributes may be utilized to provide a description of the transitions that take place between its momentary states.

B. Shredding
Shredding is the only answer that has a physical change in a material, the rest are only chemical changes
hope this helps!
