Question 23 (1 point) A student is given an object with a mass of 14.8 grams. When placed into a
graduated cylinder the water level rises from 25.0 mL to 34.7 mL.
What is the density of the object and would you expect it to float or sink in the
graduated cylinder if water has a density of 1.00 g/mL? Show all of your work.

d = 1.53 g/mL

Object will sink into water

Explanation:

Given data:

Mass of object = 14.8 g

Initial volume of water = 25.0 mL

Final volume after adding object = 34.7 mL

Density of object = ?

Density of water = 1.00 g/mL

Solution:

Volume of object = Total volume - volume of water

Volume of object = 34.7 mL - 25.0 mL

Volume of object = 9.7 mL

Density of object;

d = mass/volume

d = 14.8 g /  9.7 mL

d = 1.53 g/mL

The density of water is 1.00 g/mL which means object is heavier than water thus object will sink into the water. The object with density less than water are float in it.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
