What kind of change, physical or chemical, is happening when wood burns? How can you tell?

Answers

Answer:

Wood changes chemically to carbon dioxide when it burns and leaves a residue of ashes. These ashes cannot be changed back to wood. So it is a chemical change.

chemical
physical means it can go back to its shape; chemical it cannot.
for example when wood burns you can’t get that wood back to before it was burned!

Sodium is a metal (Na), what makes the Neutral atom of Sodium different
from the lonized atom of Sodium

A neutral atom has more protons than an ion

Neutral atoms have more neutrons than an ion of an tom

Neutral atoms have a charge while ions do not

Neutral atoms have the same amount of protons and electrons while an ion has
either gained or lost an electron

Answers

Answer:

D

Explanation:

An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.

The answer is D. What makes a neutral atom neutral is that it has an even number of protons and neutrons. If the number of protons and neutrons are unbalanced, it is now an ion.

The Barber's have a circular flowerbed in their front yard. The want to put fertilizer on ha

Answers

Answer:

C

Explanation:

a fish cant breath outside water

Mammals use their lungs to provide oxygen from the air, while fish spend time in the water; instead, fish developed gills because gills allow the fish to use the oxygen that is dissolved in the water, which is option c.

What is the significance of the gills in animals?

Gills are important for fish and other aquatic animals as they are the primary respiratory organ in aquatic animals, helping them obtain oxygen from water and release carbon dioxide into the surrounding water. Gills in fish and other aquatic animals help them breathe underwater and maintain vital metabolic processes.

Hence, mammals use their lungs to provide oxygen from the air, while fish spend time in the water; instead, fish developed gills because gills allow the fish to use the oxygen that is dissolved in the water, which is option c.
