An astronomer is describing an orbiting body she recently observed. Based on this description, determine which region of the solar system the body is most likely to reside in:
At its closest, the observed body was 2.4 AU from the Sun. At this point, we were able to determine that it was composed primarily of rock and metal, although we do not know exactly which metals it contains. Its orbit is not a perfect ellipse because it moves slightly every time Jupiter passes by.
asteroid belt
inner planets
outer planets

Which statement best describes a physical change?
1 Changes can occur to certain chemical properties of the substance, but the overall shape of the substance will remain the same.
2 Changes can occur to certain physical properties of the substance, but the overall shape of the substance will remain the same.
3 Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same.
4 Changes can occur to chemical properties of a substance, but the chemical composition of the substance remains the same.
Answer: 3 Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same
Explanation:
Physical change mainly physical properties of a substance while the chemical changes remain unchanged. Once there is a change to the chemistry of the substance, this would be classified as a chemical change.

D. 72 protons, 72 electrons, and 48 neutrons
Option 5
Answer:
a
Explanation:
proton remains same as the atomic number
electron remains same as the atomic number
Mass no.- atomic no. = Neutrons
Claim: An ecosystem can survive with only producers.
Do you agree or disagree with this claim? Explain your answer. Be sure to include evidence and reasoning.
Answer:
No.
Explanation:
The reason for this is if everything in an ecosystem was a producer there would be nothing consuming and soon the ecosystem would be overwhelmed by two many products and nothing to consume them. A healthy ecosystem is a balanced cycle that makes sure everything is working properly and everything benefits something else. A food chain of sort is often seen in a balances ecosystem to show how everything is useful and needed. So in answer if there were only producers an ecosystem wouldn't thrive at its full potential, if at all.

Water quality tests show the presence of a single heavy metal in the drinking water pulled from a local river. Residents are suffering from numerous stomach ailments and are showing signs of long-term kidney damage. The residents of the next town, down river from the first town, seem to be unaffected. Water quality tests in the river by the second town show two types of heavy metals at acceptable legal limits in the water. One of the metals is the same as the one in the first town. What can scientists infer about the possible reason for the illnesses appearing in the first town but not the second?
One metal causes an acute effect, compared to the other.
One metal causes a chronic effect, compared to the other.
The heavy metals have a synergistic relationship when combined.
The heavy metals have an antagonistic relationship when combined.
Answer:
One metal causes a chronic effect, compared to the other
Explanation:
because the question only said ONE is the same, didn't they? so that would mean that not all the metals are the same for both towns
A molecule is made up of more than one element ?
Answer:
Yes it is
Explanation:
How else do you think nitrogen or oxygen is made?
204,900,000,000
How many significant digits are found?
Answer:
4
Explanation:
There are 4 significant figures because when there is not a decimal, then only numerical values over 0 are counted. So the numbers counted in sig figs are 2049, and none of the other 0s.
So if it was 204,900,000,000.0, then it would have 12 significant figures.

2. A student wants to calculate the heat gained of 100 grams of water in order to
calculate the specific heat of a metal in the following problem. The water is
heated from 25C to 50C when the metal is added. The specific heat of water is
4.18 J/gºC. Use Q=m x CXAT*
5,225 J
10,450 J
20,900 J
Taking into account the definition of calorimetry, the correct answer is the third option: The heat exchanged is 10,450 J.
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
The amount of heat (Q) necessary to vary the temperature of a mass (m) of a substance is proportional to the change in its temperature (∆T) and to that mass. So, the equation that allows calculating heat exchanges is:
Q = c× m× ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
c= 4.18 [tex]\frac{J}{gC}[/tex]m=100 gΔT= Tfinal - Tinitial= 50 C -25 C= 25 CReplacing in the expresion for calorimetry:
Q = 4.18[tex]\frac{J}{gC}[/tex]× 100 g× 25 C
Solving:
Q= 10,450 J
Finally, the correct answer is the third option: The heat exchanged is 10,450 J.

brainly.com/question/11586486?referrer=searchResults brainly.com/question/24724338?referrer=searchResultsaluminum can be used to make soft drink cans because of which property?
A. It can be hammered into a thin sheet (malleability)
B.it can reflect light (shininess)
C.It can be drawn into long wires(ductility)
Answer:
A
Explanation:
Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A soda can's walls are very thin, and therefore express the malleability of aluminum.
