When heat is produced by a reaction, would you call it a chemical change?
Answer:
However, in this case, one compound is mixed in with another, and these reactants produce a product. When the reactants are mixed, the temperature change caused by the reaction is an indicator of a chemical change. This reaction generates heat as a product and is (very) exothermic.
Explanation:
Answer:
Thermal change
Explanation:
find the temperature change of water when the mass is 45.0g and the intial temperature is 20.0C
Answer: The answer is 41.5 C
(45.0 g)(x - 20 C) = (22.3 g)(85 C - x )
45.0x + 900 C = 1895.5 C - 22.3x
+22.3 x - 900 C = -900 C + 22.3 x
67.3x = 2795.5
2795.5 / 67.3 = 41.54 C

Which is true about what models allow us to do to the system being studied? Question 8 options: Increase the amount of waste produced. Decrease what we learn about a system. Decrease the amount a system is studied. Increase the size of a very small system, allowing easier understanding of what is occurring.
Answer:
Increase the size of a very small system, allowing easier understanding of what is occurring.
Explanation:
Models allow us to increase the size of a very small system, allowing easier understanding of what is occurring .
This can be explained with the help of an atom model. An atom model helps students understand what is happening inside the atom by making the atom large enough to be seen with the naked eye. Once the thing can be seen with the eyes it is easier for the brain to interpret chemical reactions or chemical charges inside the atoms.

Explanation:
When radioactive uranium decays to produce thorium, it also emits a particle. As seen in the balanced nuclear equation, this particle can BEST be described as
Answer:
an alpha particle or helium nucleus
Explanation:
Uranium spontaneously undergoes alpha decay. During an alpha decay, the uranium nucleus spontaneously decays to produce a thorium nucleus, alpha particles and energy.
The balanced nuclear equation is shown in the image attached to this answer for clarity.
The decay of uranium to thorium has been best described as the alpha decay.
The nuclear decay has been given as the decomposition of the atom by emitting radiations. The emission has been responsible for the change in the nucleus of the atom to the daughter nuclei with smaller mass.
The decay of Uranium to thorium has been the spontaneous alpha decay. There has been the loss in the mass of uranium in the form of energy, resulting on the thorium nucleus.
Thus, the decay of uranium to thorium has been best described as the alpha decay.

You are part of a scientific team designing a space probe that will land on Saturn's moon Titan. Your task is to write a report detailing the conditions the probe will need to withstand and propose some materials to be used in the construction of the probe.
Answer:
Material required to construct the Probe is :
Palladium based alloy, nickel based alloys, rhenium tungsten, wires, piping, duct, roofing membrane, aluminium or titanium body and circuit.
Explanation:
Probe is a robotic aircraft used to explore the galaxy. It does not revolve in the orbit. It goes beyond the orbit and explores the different planets. These probes are used by scientists to collect information regarding the space without sending an astronaut. Probes are sent into the space, they collect information and transmits data to the scientists on earth.

The periodic system of elements is an arrangement of elements classified based on similar properties and their atomic number order.
The periodic system is divided into groups (vertical order) and periods (horizontal order)
In the periodic system
The group number in the periodic system is determined by the same valence electrons (main group), while the period is determined by the number of shells
The 2 valence electrons are in group 2
A : group 2 : Valence electrons =2
B: group 13 : Valence electrons = 3
C : group 15 : Valence electrons = 5
D : group 16 : Valence electrons = 6

Which statement about organisms in the fossil record is correct? A.Organisms show a decrease in diversity only right before an extinction event. B.Organisms show a steady increase in diversity, interrupted by extinction events. C.Organisms show a steady decrease in diversity, interrupted by extinction events. D.Organisms show an increase in diversity only right after an extinction event.
Answer:
Organisms show a decrease in diversity only right before an extinction event.
Explanation:
Extinction is the termination of a kind of organism or of a group of kinds. This brings to an end the existence of a particular specie of organisms.
Extinctions occur only after there is a decrease in the diversity of a specie due to specific conditions such as predators, loss of habitat etc that makes the members of that specie to become endangered.
