Matter is anything that takes up space and can be described by physical and chemical properties. Which statement
BEST differentiates chemical properties from physical properties?
A)
Physical properties are properties that can be physically seen or touched,
while chemical properties can only be found when matter is mixed with
specific chemicals.
B)
Physical properties are measured when matter changes its physical state,
while chemical properties can only be measured if matter remains in one
state for an extended time.
C)
Physical properties are difficult to measure because they require special
tools to detect, and chemical properties are easy to measure and require
not special tools to detect.
D)
Physical properties can be measured/observed without changing matter
into something else, while chemical properties describe matter's ability to
react/combine with other matter.

Answer:

D)

Physical properties can be measured/observed without changing matter

into something else, while chemical properties describe matter's ability to

react/combine with other matter.

Explanation:

Physical Change                                                                                              

The changes that occur only due to change in shape or physical properties but their chemical or internal composition remain unchanged.  

1 = These changes were reversible.

2= They have same chemical property.

3= These changes can be observed with naked eye.

Example :

Water converting to Ice

Water converting to gas

In this water molecule remain the same only they rearrange themselves that change its state of mater not composition

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

1 = These changes are irreversible

2 = These changes occur due to chemical reactions

3 = These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO₂ and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

The reaction of Hydrogen and oxygen:

H₂ (g)  + O₂  (g)   →    2H₂O  (l)

Which of the following elements has the largest electronegativity? A) Bismuth B) Nitrogen C) Potassium D) Arsenic​

A hypothetical element has two main isotopes with mass numbers of 59 and 62. If 73.00% of the isotopes have a mass number of 59 amu, what atomic weight should be listed on the periodic table for this element? Answer in units of amu.

4. Advection fog forms when warm moist air comes in from the Pacific Ocean and

blows over the cold California current.

A.True

B.False

Nio conducts a science experiment. He puts yeast into a bottle with water and sugar, and then caps the bottle with a balloon. He returns two hours later and notices there are bubbles on the surface of the mixture in the bottle and that the balloon has inflated, but there are no other apparent changes.
What most likely happened?

a non-chemical change, because there are no indicators of chemical changes taking place
a chemical change, because the mixture changed color
a chemical change, because a gas was produced
a non-chemical change, because the changes that occurred are reversible

All surfaces have texture, which means it affects how things move over it. When it takes a long time for friction to slow down an object, what is most likely true about the surface the object is moving on? The surface is dry. The surface is rough. The surface is uneven. The surface is smooth.

Answer question number 3

Plz help! :) :D I will mark you as BRAINLIEST for the best answer!!! ( I actually mean it)
Physical and Chemical Properties of Magnesium

Here is an EXAMPLE of how it has to be like. Instead of Mercury, you HAVE to do Magnesium

Physical Properties of Mercury: ”I’m a highly stable element, so you can count on me”

Chemical Properties of Mercury: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon”

Determine the mass of 31.4 moles of Sodium.
