Answer:
A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra.
Explanation:
Answer: -
Lower the specific heat capacity of the metal, more the amount of heat would be required to raise the temperature to the same extent.
So for the same amount of heat added to 5.00 g samples of metals, the metal with the lowest specific heat capacity would experience the smallest temperature change.
For example, if the elements are Al, Au ,Cu and Fe, then Au would experience the smallest temperature change due to least specific heat capacity.
Answer:
157.8 g
Explanation:
Step 1: Write the balanced equation
Fe₂O₃ + 3 CO ⟶ 3 CO₂ + 2 Fe
Step 2: Calculate the moles corresponding to 209.7 g of Fe
The molar mass of Fe is 55.85 g/mol
209.7 g × 1 mol/55.85 g = 3.755 mol
Step 3: Calculate the moles of CO needed to produce 3.755 moles of Fe
The molar ratio of CO to Fe is 3:2. The moles of CO needed are 3/2 × 3.755 = 5.633 mol
Step 4: Calculate the mass corresponding to 5.633 moles of CO
The molar mass of CO is 28.01 g/mol.
5.633 mol × 28.01 g/mol = 157.8 g

1. 
Explanation:
2. <em>Seismic</em> <em>waves</em> vibrate from side to
side and up and down. They go through solids only, travel slower than <em>Pressure</em> [or <em>Primary</em>] <em>waves</em>, which arrive second, and shake the ground violently.
1. A <em>Ritcher</em><em> </em><em>scale</em><em> </em>senses the magnitude of earthquakes.
