Step-by-step explanation:
Use PEMDAS (solve for parenthesis first):
4(2 + -3)2
4(2 - 3)2
4(-1)2
(-4)2
-8
Almost all stoichiometric problems can be solved in just four simple steps:
- Balance the equation.
- Convert units of a given substance to moles.
- Using the mole ratio, calculate the moles of substance yielded by the reaction.
- Convert moles of wanted substance to desired units.
Answer:
Not exactly sure if you are asking to simplify, but that is all I can do with the information you have given.
Here is the simplified version:
−2.3d + 4.7h − 15
Step-by-step explanation:
Combine Like Terms:
=8h+−6.3d+−15+4d+−3.3h
= (−6.3d+4d) + (8h+−3.3h) + (−15)
= −2.3d+ 4.7h − 15
