why would someone need to find the relative density of an object?

Answers

Answer 1

Answer:

The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

Explanation:

Hope it helps!

Answer 2

The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

This principle is fundamental to understanding why objects float or sink in fluids and are commonly observed in everyday situations. For example, ships and boats float on water due to their design and the distribution of weight, while heavy materials like metal sink in water because their density is greater than that of water.

Therefore, The concept of relative densities and buoyancy has significant applications in various fields, including shipbuilding, architecture, swimming, and understanding the behavior of objects in liquids.

What was the effect of decreasing the copper's mass?

Answers

Answer:

Decreasing the temperature of the copper made the final temperature decrease.

Heat emitted by copper reduces as copper's mass decreases. As the mass of copper lowers due to a decrease in heat gain by water, the final temperature also drops.

What is heat?

The transfer of kinetic energy from an energy source to a medium, an object, or from one to the other is referred to as the creation of heat. The sun is the source of all energies. It is the natural source of solar energy, heat, and light. Thermal energy can move through three different channels: conduction, convection, and radiation.

Therefore, the increase in temperature is always proportionate to the mass of water. Thus, the final temperature will be lower if we increase the water mass. The temperature will be lower in the end. The density reduces as volume grows. Consequently, density drops as temperature rises.

Thus, heat emitted by copper reduces as copper's mass decreases. As the mass of copper lowers due to a decrease in heat gain by water, the final temperature also drops.

How many grams of solute are needed to order to prepare 100.00 mL of a 0.1000 M solution of a compound with a molecular weight of 350.0 g/mol

Answers

Answer:

i got 35 but i am as lost as you are so don't really take my answer as a trusted answer

The grams of solute are required.

The mass of solute is 3.5 g

c =  Molarity = 0.1 M

M = Molar mass = 350 g/mol

V = Volume of solution = 100 mL = 0.1 L

n = Number of moles

m = Mass of solute

Molarity is given by

[tex]c=\dfrac{n}{V}\\\Rightarrow n=cV\\\Rightarrow n=0.1\times 0.1\\\Rightarrow n=0.01\ \text{moles}[/tex]

Molar mass is given by

[tex]M=\dfrac{m}{n}\\\Rightarrow m=Mn\\\Rightarrow m=350\times 0.01\\\Rightarrow m=3.5\ \text{g}[/tex]

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.

The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.

A gas measures 140 mL at 400 K find its volume at 120 K if the pressure remains constant.

Answers

By applying Charles law, the final volume of the gas is equal to 42 mL.

Given the following data:

Initial volume = 140 mLInitial temperature = 400 KFinal temperature = 120 K

To find the final volume of the gas, we would apply Charles law:

Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by the formula;

[tex]\frac{V}{T} =k\\\\\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

Where;

T is the temperature of an ideal gas.V is the volume of an ideal gas.

Substituting the given parameters into the formula, we have;

[tex]\frac{140}{400} = \frac{V_2}{120} \\\\140 \times 120 = 400V_2\\\\16800 = 400V_2\\\\V_2 = \frac{16800}{400}[/tex]

Final volume = 42 mL.

Round your answer to the second decimal.

Answer:

Hydrogen Chloride is 74.64 grams.

Explanation:

Using the given information, we can find the amount of grams of hydrogen chloride that take place in the reaction.

24.30 grams of Magnesium"x" grams of Hydrogen chloride2.04 grams hydrogen gas96.90 grams of magnesium chloride.

Due to the Law of Conservation of Mass, the mass of the system must remain constant. To find the value of x, make the equation below.

[tex]24.30 + x=2.04 + 96.90[/tex]

The left side represent the reactant side of the chemical reaction and the right side represents the product side.

[tex]2.04 + 96.90= 98.94[/tex]

[tex]24.30+x=98.94[/tex]
