Nicole is making a cake for a class project when her sister takes a cup of sugar and puts it into one of the two water glasses. What kind of mixture is the sugar-water?

Teresa stays home from school because she has a cold. Her father makes her chicken noodle soup and urges her to drink lots of orange juice. Both the soup and juice are mixtures, but one is a homogenous mixture and the other is heterogeneous. Which food item is homogenous and which is heterogeneous?

The diagram above presents a stylized version of the separation of crude oil and its various byproducts. Crude oil is made up of a mixture of hydrocarbons, and the process separates this crude oil into broad categories of its component hydrocarbons, or 'fractions.' Crude oil is first heated in what is known as a still, where different products boil off into a gas and are recovered at different temperatures returning them to liquid form. What method of separating mixtures is the above paragraph describing?

The brine pool can be described as which type of mixture? Choose all that apply.

Sierra helps her father install an air purifier in her house. What type of separation method does an air purifier use to remove dust and allergens from the air?

Which of the following is a suspension?

What is the weight of a 45 kg woman standing on Earth?

You want to find a piece of pyrite weighing 20 lbs on earth. You want to find out how much matter it contains. What is the mass of the piece of pyrite?

What is the weight of an astronaut on the moon if their true mass in space was 90 kg?

Apollo 17 astronauts Eugene Cernan and Harrison Schmitt collected the last samples of moon rocks to bring back to Earth in 1972. The astronauts took measurements of the moon rocks in three categories not affected by gravity. This is because the Earth and moon have different forces of gravity. Which measurement did they not use?

A whale weighs about 330,000 lbs on earth. What will the blue whale's new weight be on the surface of Jupiter?

A company called spin launch is looking to launch satellites into low orbit within the next five years. They first want to test a rocket that weighs 500lb and send it directly to space from earth. What will its mass be once it leaves earth's orbit?

The Rosalind Franklin rover is set to launch in 2028 from Earth to Pluto. Its weight sits at 680 lbs. What will Rosalind Franklins' final weight be when it reaches Pluto (Acceleration of gravity is 0.62 m/s²)?

How could you separate a mixture of iron filings and sand?

Filtration cannot be used to separate

What is an example of a SOLVENT:

A student measures 5 grams of sugar into 50 milliliters of water in a Erlenmeyer flask. Which of the following should the student do to help the solubility of the sugar?

A group of students observes behaviors of matter using vegetable oil and vinegar salad dressing. The students perform an investigation using similar substances. When someone shakes a container full of different objects, they may mix together. Objects that are similar in size mix the most. When some objects are smaller than others, the smaller objects usually sink below the larger ones. The students plan to use a different set of materials to be models for the behavior of oil and water. Which materials, if shaken, would most accurately be models for the behavior of the water and vegetable oil in the bottle?

On Venus, the acceleration due to gravity is approximately 8.87 m/s². Calculate the mass of the Venera 7 as it leaves Venus to head back to space. It weighs 2,600 lbs on Venus.

You are making Kool-aid for your baseball team and want to make sure its not gritty from undissolved sugar. What should you do to increase the solubility?

You are at a local coffee shop and watch as a barista makes a Mocha. Based on the listed ingredients select from below the solvents only.

What type of mixture is pictured?

Weight is a flawed measure of mass because:

Based on the graph where temperature affects the rate of solubility of different solutes. You can see NH₃ drastically decreases as temperature increase making it a:

An astronaut is preparing to head home after a quick trip to saturn (Acceleration of gravity 10.44 m/s²). The first part of the trip is leaving Saturns gravitational pull. Calculate the 360 lb astronauts true mass as they head out to space.
