First convert the inches cubed to centimeters cubed. Looking at the rate, we can write 2 inches cubed = 2 * 16.39 cm cubed = 32.78 cm cubed.
The equation for density is D = M/V, where D is the density, M is the mass, and V is the volume. Substitute the values into the equation:
0.242 = M/32.78
Multiply by 32.78 on both sides.
The mass is about 7.93 grams.
Answer:
a) will react with water: K
b) will react with steam or acid, but not water: Cr & Sn
d) will not react with water, steam, or acid: Cu
Explanation:
K reacts violently with water.
Cr will react with steam to form an oxide + H gas and will react with most acids
Sn will react with steam to form SnO₂ + H gas and, though it does not react as rapidly as other metals in acid, it dissolves easily in concentrated acids
Cu is an extremely nonreactive metal, which is what makes it so suitable for wiring
The answer is gas and it involves the Kinetic molecular theory which is a model used to predict gas behavior. Molecules or atoms
