A graduated cylinder was filled with 25.0 mL of water. A solid object was immersed in the cylinder, raising the water level to 3
1 answer:
Answer:
Density of the object is 8759.494 grams/L
Explanation:
As we know density of an object is mass of the object divided by its volume
Given
Volume of the object is equal to the change in volume of water with in the cylinder when the object was immersed in water.
Hence, volume of object is equal to
mL
Mass of the object is grams
Density
grams/L
Density of the object is 8759.494 grams/L

Answer: 40.3 L
Explanation:
To calculate the moles :
According to stoichiometry :
1 moles of produces = 3 moles of
Thus 0.600 moles of will produce=
of
Volume of
Thus 40.3 L of CO is produced.
There is a rule in naming polyatomic anions containing oxygen.
Those names ending in <em>–ate</em> are given to the most common oxyanion of an element.
While those names ending in <em>–ite</em> are for those that contains fewer O atom for
the same charge. Since P has fewer O atoms, its name ends in <em>–ite</em>.
Thus, P
is phosphite while P
is phosphate.
