Which of these accurately describes a chemical reaction?
products combine to form reactants.
products and reactants combine to form new reactants.
reactants combine to form products
products and reactants combine to form new substances

The correct answer is C. Reactants combine to form products

Explanation:

A chemical reaction occurs as two or more substances interact, and this leads to the formation of new substances. In this context, the initial substances are known as reactants, while the substances at the end of the process are known as products. For example, by combining Carbon and Oxygen (reactants) you obtain Carbon Dioxide (Product) (C + O2 = CO2). Additionally, reactions can be of different types depending on the products obtained, this includes decomposition, synthesis and replacement reactions. According to this, the option that best describes a chemical reaction is "Reactants combine to form products".

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
