What substances easily pass through the plasma membrane?
oxygen
Does not pass easily through plasma membrane?

Can Homogeneous mixture be decomposed into other substances by chemical processes?
can it be decomposed into other substance by a chemical processs
Are separations of mixtures physical or chemical changes?
Physical. Salt water is a mixture, and you can separate it into NaCl and H2O simply by evaporating the water. As long as it does not change the chemical composition of the molecules, it is a physical change.
Is ability to freeze a chemical property of matter?
No, changes in state are classed as physical changes as no new substance is made amd the process is easily reversed.
What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
What is chemical evidence?
Chemical Changes involve a change in chemical composition in the substances which are being investigated so you cannot easily get back your original substances as something new has been formed. Some examples of chemical changes are a gas is produced, the temperature changes, a substance disappears, a solid is formed, a color change occurs, and a new odor is produced.
What substances easily pass through the plasma membrane?
oxygen
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
What kind of blood vessels allow substances to enter and leave the blood easily around the cells?
Capillaries. they have such thin walls that substances can easily diffuse through them.
What are heat conductors and heat insulators?
the substances that allow heat to pass through them easily are called heat conductors. the substances that do not allow heat to pass through them easily are called heat insulators. ruchi

Meeting butter for popcorn is physical or chemical?
physical because it can return to its solid state by cooling. chemical changes can not be reversed so easily
Why do you think the sublimation of dry ice and expansion of gases are not chemical reactions?
Because they are changes of state - physical changes - VERY easily reversed.
Any material that allows electricty to pass through it easily?
Conductors, and or super conductors, such as copper. Substances such as rubber tires are known as resistors, and cannot let electricity pass through easily.
Can Homogeneous mixture be decomposed into other substances by chemical processes?
can it be decomposed into other substance by a chemical processs
Is there a chemical that absorbs the chemical mercury?
Mercury, or quicksilver, is highly toxic and can be easily absorbed through human skin. There is no known chemical that absorbs mercury.
