If two types of matter are combined and energy is given off, what type of change is likely to have occurred? chemical change

physical change

particle change

shape change

Chemical change

Explanation:

If two types of matter reacts or are combined and energy is given off, the type of change that might have occurred is a chemical change. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible. When an exothermic reaction or change occurs, heat is released and it is a typical characteristic of chemical change.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
