Filtration is when matter is passed through a filter and the larger particles

are separated out. Magnets can be used to separate magnetic matter from

 A car follows a curved highway from point a to point B covering a distance of 50 km and displacement to the east of 40 km in 0.5 hours. What is the speed and velocity of a car in kilometers per hour? Speed: Km/h. Velocity: Km/h.

Answers

Distance = 50 Km

Displacement = 40 Km

Time = 0.5 hours

We know, speed = [tex] \sf \frac{distance}{time} [/tex]

Therefore, the speed of the car

[tex] \sf = \frac{50}{0.5} = 100[/tex]

We know, velocity = [tex] \sf \frac{displacement}{time} [/tex]

Therefore, the velocity of the car

[tex] \sf = \frac{40}{0.5} = 80[/tex]

Answer:

Answer:The speed of the car is 100 Km/h. The velocity of the car is 80 Km/h to the east.

Melting gold with other metals makes 10-karat gold. Which term best describes 10-karat gold?
compound
homogeneous mixture
heterogeneous mixture
pure substance

Answers

Answer:

I think its a homogeneous mixture (pls correct me if im wrong)

Explanation:

It is a homogeneous mixture because its an alloy made of gold, silver, copper, and other metals that are melted together. A homogeneous mixture is composed of a uniform composition of particles.

There are two types of mixture, one is homogeneous mixture and other is heterogeneous mixture. Therefore, the term best describes 10-karat gold is homogeneous mixture.

What is mixture?

When two or more compounds are combined but each ingredient retains its chemical identity, the result is referred to as a mixture. In other words, there is no chemical interaction between the parts of a combination. According to how consistent they are and how well the components' particle sizes match up, mixtures are categorized.

Because it is an alloy comprised of melted gold, silver, copper, and other metals, it is a homogenous combination. A homogeneous mixture has a consistent distribution of its constituent particles.

Therefore, the term best describes 10-karat gold is homogeneous mixture.

Part 1: Name the type of chemical reaction that occurs when aluminum (Al) reacts with copper nitrate (Cu(NO3)2).

Part 2: Explain why aluminum does NOT react with potassium nitrate (KNO3) although it reacts with copper nitrate.

Answers

Single-displacement reaction occurs when aluminum reacts with copper nitrate.

Single-displacement reaction is the type of chemical reaction that occurs when aluminum (Al) reacts with copper nitrate (Cu(NO3)2). In this type of reaction, aluminum takes the place of copper and produced aluminium nitrate.

Aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate because potassium nitrate (KNO3) is a stable compound which held each other very tightly so we can conclude that Single-displacement reaction occurs when aluminum reacts with copper nitrate.

In one to two sentences, explain how to compare the strength of electrostatic forces between molecules in salt water to the strength of electrostatic forces between molecules in freshwater. Include a description of the data to be collected and how that data would allow one to draw conclusions about the relative strengths of the electrostatic forces in the two substances.

Answers

The boiling point of salt water is greater than that of fresh water hence the electrostatic forces between molecules in salt water is greater than that between the molecules in salt water.

Fresh water contains does not contain dissolved solutes like salt water. Salt water contains a lot of dissolved mineral salts making the salt water to be rich in ions.

Generally, the boiling points of substances can serve as a measure of the strength of electrostatic forces between molecules in either kind of water. We will easily find the that the boiling point of salt water is far higher than that of fresh water indicating greater electrostatic forces between molecules in salt water than between molecules in fresh water.

Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option A.  Temperature is a physical quantity.

What is temperature?

Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.

Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Heat always flow from higher temperature source to lower temperature source.

We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:

°C={5(°F-32)}÷9
