What Pluto observations did not help convince scientists to change Pluto's status from that of a planet?
Observations of Pluto's orbit and size did not provide enough evidence to change its status from a planet. Astronomers cited factors such as its small size and irregular orbit as reasons for excluding it from the planetary classification.
What are 3 ways you know a chemical change has taken place?
Three signs of a chemical reaction include the release or absorption of heat, a change in color, and the creation of a gas or a precipitate.
What are 3 observations that would tell you that new products had been made in a reaction?
Change in color or appearance of the mixture. Evolution of gas or formation of bubbles. Generation of heat or cooling of the reaction mixture.
Why do you do neurovascular observations?
Neurovascular observations are performed to assess and monitor the integrity of the nervous system and blood flow to the brain. These observations help identify potential complications, such as stroke or neurological deficits, enabling timely intervention and treatment. By regularly checking vital signs, neurological status, and vascular health, healthcare providers can ensure patient safety and optimize outcomes.

What are the signs of physical change from a chemical change?
Signs of a chemical change include the formation of a new substance, a change in color, production of gas or bubbles, release of heat or light, and a change in odor. These changes are not easily reversible and often involve the rearrangement of atoms.
What Pluto observations did not help convince scientists to change Pluto's status from that of a planet?
Observations of Pluto's orbit and size did not provide enough evidence to change its status from a planet. Astronomers cited factors such as its small size and irregular orbit as reasons for excluding it from the planetary classification.

What are signs of a chemical reaction?
Some signs could be: *solids forming *bubbles *color change *temp. change
Why have scientist change their ideas on the model of the Atom?
There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.
