Answer:
Explanation:
The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails
Answer:
A chemical change because a temperature change occurred, the solid disappeared and a gas was produces
Explanation:
Magnesium reacts with hydrochloric acid releasing energy, and leading to the formation of magnesium chloride and hydrogen gas. This is represented by the equation below:
Mg₍s₎ + 2HCl₍aq)⇒ MgCl₂₍aq₎ + H₂₍g₎
Permeable materials for what
Answer:
a. NO2
b. NH3
c. CO2
Explanation:
a. For the pair of compounds CO2 or NO2 the one with the highest boiling point is __________ .
The answer is NO2. It has a higher boiling point than CO2 because it exhibits dipole-dipole interactions.
b. For the pair of compounds NH3 or CH4 the one with the highest boiling point is _________
NH3 has a higher boiling point compared to CH4. This is due to the presence of the hydrogen bonds in NH3,
c. For the pair of compounds CS2 or CO2 the one with the highest boiling point is _________
CS2 has a higher boiling point than CO2. This is because of the high molecular mass of CS2.
