The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: The equation was CaCO3 →CaO+CO2
He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer. Draw a model showing the number of each type of atom in the reactants and products. Use your model to explain your answer.
PLEASE HELP
Yes, our friend is right, because there is no contradiction to the law of conservation of mass in the above equation. It just the mass of the product is equal to the mass of reactants.. and that is shown in the equation you have presented earlier
Answer:correct

If I double the velocity of a moving object, what happens to the object’s energy?
Answer:
Kinetic energy is proportional to the object's velocity squared. This indicates that when an object's velocity doubles, the object's kinetic energy quadruples.
Explanation:
Please complete this in 3-5 sentences.
Answer:
Magnetic forces are stronger closer to magnets. The Wednesday launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.

what is a waxing gibbous?
Answer:
Waxing gibbous: more than half-lit, less than full
The word gibbous comes from a root word that means hump-backed. People often see a waxing gibbous moon in the afternoon, shortly after moonrise, while it's ascending in the east as the sun is descending in the west.

hope this helps! ;)
A regular object has the following dimensions: Height 10cm, Length 13cm, Width 5cm. What is the volume of this object?
Answer:
650
Explanation:
To find the volume of an object, you need to multiply height x length x width
13 times 5 is 65
10 times 65 is 650
[tex]\text{Volume,} ~V= 10~ cm \times 13~ cm \times 5~ cm = 650 ~ cm^3[/tex]
As crust forms at the mid-ocean ridge, it gets pushed away from the ridge as newer crust forms. What is true about crust that forms at the mid-ocean ridge?
A: crust further away from the mid-ocean ridge is younger and crust closer is older
B: crust further away from the mid-ocean ridge is older and crust closer is newer
C: crust is not created at the mid-ocean ridge
D: crust further away from the mid-ocean ridge and crust closer are the same age

Here’s the last two questions again, tysm!
Answer:2 possible ways for question 16 and for question 17 they could be two posible causes
Explanation for 16:
1)you can use velocity like a rocket fast enough to reach the meteor and crush it mid way to earth 2)you can use mass like a big rock but if the meteor is to big then use velocity too for it can help the mass have a big colisio whit the asteroid whit a catapult or a big launcher and the moon gravity can help to because of the force
Explanation for 17:the two were in a different road and the one that is sideways was at a bigger speed then the car left in the middle and because of the mass the collision was worse For the one in the middle

Explanation:
Types of crust found at certain tectonic boundaries (earths layers)
Pls answer I need to finish this assignment
Answer:
The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.
You are doing a project to determine weather the amount of air in a ball determines how high it bounces. What is the independent variable
Answer:
The Independant Variable Would Be The BALL
Explanation:
This is because an independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. The ball doesn't change size or type ( Basketball , Football ETC.)
Answer:
The ball

Just find the steady acceleration
Answer:
the steady acceleration is 4m/s^2
Explanation:
all you need to do for the speed is add 4 to the last number to get the next one. in your case you want to find the speed after 3seconds and 5 seconds so just add 4 to 8 to get the first one then add 4 to 16 to get second one
1s 2s 3s 4s 5s 6s 7s
4m/s 8m/s 12m/s 16m/s 20m/s 24m/s 28m/s
Answer: the steady acceleration is 4m/s^2 ( give the other guy brainliest)
Explanation:
