Volume of cube = a³
2.50 * 2.50 * 2.50 = 15.625 cm³
Density = 8.90 g/cm³
mass = ??
m = D * V
m = 8.90 * 15.625
m = 139.0625 g
hope this helps!
When the water level of a stream or river exceeds its natural banks, it has reached its D. FLOOD STAGE
Flood stage is an established gauge height for a given location above which a rise in water surface level begins to create a hazard to live, property, or commerce. The issuance of flood warnings are the result of flood stage.
Oil<span> and </span>water<span> are two liquids that are </span>immiscible<span>, meaning they will not mix together. Liquids tend to be </span>immiscible<span> when the force of attraction between the molecules of the same liquid is greater than the force of attraction between the two different liquids.</span>
Answer:
no effect
Explanation:
In an SN2 reaction, the mechanism is bi-molecular and first order in both the alkyl halide and the nucleophile.
Hence the rate of reaction is;
Rate = k [1-iodo-2-methylbutane] [cyanide ion]
Given that it is a bimolecular reaction, if we double the concentration of 1-iodo-2-methylbutane and the concentration of the cyanide ion is halved, the rate of reaction remains the same.
Answer:
Atomic# : 11 ( # of protons)
mass# : 22 ( sum of protons + neutrons)
neutrons: 11 (mass# -atomic#)
# of electrons : 10 (atomic# - charge)
