Alison finds the total mass of a sample of baking soda, a balloon, and a glass container with vinegar in it. She adds the baking soda to the vinegar and immediately places the balloon over the mouth of the container. After the reaction is complete, she again finds the total mass of the system.

Which statement is true:
1. The mass does not change because chemical changes observe the law of conservation of mass.
2. Mass is gained during the reaction because a chemical change is taking place.
3. Mass is lost during the reaction because the gas is less dense than the baking soda or vinegar.
4. Mass is lost during the reaction because the gas can change in volume but baking soda and vinegar cannot.

Answers

Answer 1

Answer:

2. Mass is gained during the reaction because a chemical change is taking place

whats is the cell cycle and why is it so important to to our health? no links

Answers

The cell cycle is the replication of reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in many different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called binary fission, allows for them to live on by dividing into two new daughter cells. ( I hope this helped if you are doing this on computer you can copy & paste it. )
Are you talking about cell division and mitosis and that kind of stuff? If so , first is interphase which is growth and development second is prophase where you can see the chromosomes and spindle fibers everywhere, third is metaphase where the chromosomes line up and the spindle fibers are attached to the chromosomes, fourth is anaphase where the chromatid pairs separate, and last is telophase where the cell begins to form a new nucleus and split and goes back to interphase and the cycle continues. If this stopped then you would die. I hope this helped

Which is the independent variable?

Answers

Answer:

First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.

PLZ HELP!!!! I NEED A ANSWER AND THE FIRST ONE TO ANSWER WILL GET A BRAINLIEST!!!!

Answer:

3miles per hour^2

Step-by-step explanation:

given data

initial speed u= 15mph

final speed v=45mph

time taken t= 10 seconds

Step two:

Required

acceleration a=?

applying the first equation of motion

v=u+at

substitute we have

45=15+a*10

45=15+10a

make a subject of the formula

45-15=10a

30=10a

divide both sides  by 10

a=30/10

a=3miles per hour^2

Answer:

3m/s

Explanation:

15mph is the intial and 45 is the final subtract them and divide by ten

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!

Answers

Answer:

Seat belts are in cars to the effects of inertia. ... When the car hits the wall, you would keep moving in a straight line and at a constant speed until the dashboard applies a force. Seat belts hold you and passengers down, protecting them from their own inertia.

Explanation:

their is the answer so okay

Answer:

Inertia is the tendency of an object to resist a change in velocity.  

When a car stops suddenly, your body is still going at the same speed the car was before it stopped (say 65 MPH). Without the belt strapping you in from behind, you would fly forward at nearly that same speed (65).

But thanks to the seatbelt, it stops your body's inertia.

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!

Answers

Answer:

Inertia- the tendency of an object to resist a change in velocity

Explanation:

Say a car was going at 65 MPH, but suddenly stopped. For all of the people in that car, their bodies would keep moving forward at 65 MPH until stopped by an equal force (say, the thing right in front of each person) The seatbelt is there to protect you from your own inertia.

Answer:

inertia is the constant state of movement so seatbelts stop that when you stop the car.

What makes greenhouse gases different from other atmospheric gases?

Greenhouse gases reduce the amount of natural resources on Earth.

Greenhouse gases allow thermal energy to pass through the atmosphere and back out into space.

Greenhouse gases account for the direction in which water and air move.

Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.

Answers

Greenhouse gases allow thermal energy to pass through the atmosphere and back out into space

Explanation:
Greenhouse gases are transparent to incoming (short-wave) radiation from the sun but block infrared (long-wave) radiation from leaving the Earth’s atmosphere

Greenhouse gases are different from other atmospheric gases for the following reason:

Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.

Thus, the correct option is D.

What are greenhouse gases?

Greenhouse gases may be defined as those gases that absorb infrared radiations which are competent to trap heat. Some examples of greenhouse gases are carbon dioxide, methane, CFCs, nitrous oxide, etc.

Greenhouse gases are more complex as compared to other gas molecules in the atmosphere. It has a structure that makes such gases more competent to absorb heat and radiate back to the Earth's surface. These gases trap the ultraviolet radiation from the sun and emit toward the earth's surface. Such gases are responsible for greenhouse effect.

Greenhouse gases are harmful to the environment as well as the health of living entities that constantly living in various ecosystems of the environment.

Therefore, the correct option for this question is D.
