What can the students expect to be true about the two masses?
The mass of the ice cubes will be greater because solids are more dense.
The mass of the ice cubes will be greater because they took up more space in the beaker.
The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker

Answers

Answer 1

The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

Matter is anything that has mass and occupy space. All substances are composed of matter. According to the law of conservation of mass, matter can neither be created nor destroyed but can be converted from one form to another.

Since mass is the quantity of matter in a substance, the mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

Why are microwaves idea for transmitting satellite communication signals?

Answers

Answer:

Microwaves are best suited because

they have a higher frequency and small wavelength

Satellite communication and Earth observation from space benefit from microwaves that can pass through haze, light rain, snow, clouds, and smoke. Because they can penetrate the atmosphere, microwaves are used. Small wavelength and high frequency is employed for this.

Microwaves are radio waves with short wavelengths and frequencies in the gigahertz (GHz) range. They can send signals over great distances without any data loss thanks to their high frequency. Without producing signal overlap or interference, they may carry a wide range of frequencies.

Electromagnetic radiations include radio waves and microwaves. In communication, both are utilized. Television and radio programs are transmitted by radio waves, but mobile phones and Wi-Fi use microwaves. Radio waves are one of the several alternatives for satellite communication.

Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.  

Using two to three sentences, summarize what you investigated and observed in this lab. I investigated how chemical compounds work and what to use to put them together.  

Why do you believe knowing how elements and compounds react together is essential in everyday matters? So, you can cook and stop injuries, these two things happen a lot in day-to-day life.  

Some elements are more "reactive" than other elements; why do you think this is? Because certain elements in the compound may react more to fire or water and many other elements.  

Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. Because if you add all the atoms, put in that’s the total amount. For example, water has one hydrogen atom and one oxygen atom, so water has two atoms.  

Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds, or do we have many compounds in this world? Yes, it is possible like water and hydrogen peroxide. The formula of water is H20 but hydrogen peroxide has one more oxygen-H202.

how many molecules of butane are contained in 25.0 ml of butane? the density of butane is 0.6011 g/ml and the molar mass is 58.12 g/mol.

Answers

Answer:  1.557 × 10²³ molecules

Explanation:

To determine the molecules of butane we can either use multiple steps or use a combined equation based on the following formulas:

Molecules of butane = Moles × Avogadro's Number

Moles of Butane = Mass ÷ Molar Mass

Mass of Butane = volume × Density

∴ Molecules of butane

   = [(volume × Density) ÷ Molar Mass]  × Avogadro's Number

   = ([(25.0 ml × 0.6011 g/ml) ÷ 58.12 g/mol] × (6.022 × 10²³ molecules/mol))

   = 1.557 × 10²³ molecules

∴ 25.0 ml of butane of density of 0.6011 g/ml contains 1.557 × 10²³ molecules.

Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.

The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.

A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.

A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.

According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.

A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.

From the information provided;

Number of moles of acid = 0.002 moles

Volume of solution=  2 L

Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M

pH = - log[H^+]

pH = - log[0.001 ]

pH = 3

From;

pH + pOH = 14

pOH = 14 - pH

pOH = 14 - 8.5

pOH = 5.5

pOH = - log[OH^-]
