When an object floats in water, it displaces a volume of water that has a weight equal to the weight of the object. If a ship ha
s a weight of 4247 tons, how many cubic feet of seawater will it displace? Seawater has a density of 1.025 g·cm-3; 1 ton = 2000 lb. (Enter your answer in scientific notation.)
1 answer:
The amount of seawater that will be displaced would be 1.3274 x
Density = mass/volume.
Since a floating object displaces its own weight, a 4247 tons ship will also displace the same amount of water.
4247 tons of seawater = 3.8528 x g
volume of 3.8528 x g seawater = mass/density = 3.8528 x
g/1.025 = 3758829268.29 cubic centimeter.
3758829268.29 = 132741.80
or 1.3274 x

Answer: metal and carbonate
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions
in water.
An acid is represented as :
1. When metal is treated with an acid such as , if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.
2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.
