A chemical reaction separates water into hydrogen gas and oxygen gas. Which of the following statements is true about the mass of the water and the combined mass of the two gases?

Responses

The mass of the water is greater than the combined mass of the two gases.

The combined mass of the two gases is much greater than the mass of the water.

The combined mass of the two gases is the same as the mass of the water.

The mass of the water is the same as double the combined mass of the two gases.

Science is based on the correspondence theory of truth, which claims that truth corresponds with facts and reality.

What steps of the scientific method did the four theories skip?

What is the ethical value of using a model organism, such as zebrafish for doing marine research on pathogens?

The organism can prevent diseases from being transmitted from one species to another, thereby reducing fish mortality.

The organism is immune to all diseases, so the effectiveness of new treatments can be studied over long periods of time.

The organism produces chemicals that can be extracted for use as antibiotics, so they are economically important.

The organism shares its physiology with humans, so testing of new drugs can be done without hurting people.

Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.

(PLEASE HELPPPP 90 POINTS!!)

Which best describes the next step in the formation of metamorphic rocks?

Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.

A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.
D.
Some of the water will evaporate on winter days but not on summer days.

Can someone help me? I probably know the answer but I'm having a brain fart.

A group of students is investigating whether air resistance depends on the size of an object. The students throw two paper pieces each with the same force. One piece of paper is flat and the other is scrunched into a ball. The distance traveled by each paper piece is shown.


Experimental Observations
Student 1 Student 2 Student 3 Student 4
Distance traveled by flat paper 0.2 m 1.2 m 1.5 m 0.8 m
Distance traveled by scrunched paper 1.5 m 2.4 m 3 m 2 m

What was the test variable (independent variable) in this experiment?
Distance traveled by flat paper
The shape of the paper
Distance traveled by scrunched paper
The number of students

ONLY DO NUMBER 5 I CAN DO THE REST....If you help i will pass you the brainliest

Help me out please and i need this by 4:00 ?

I dont know where to put this under

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
