The simplest level at which life may exist is a cell
2, 1, 2
Explanation:
Given equation of reaction:
Li + Br₂ → LiBr
In balancing any chemical equation, they must obey the law of conservation of matter. This law suggests that the number of moles of reactants and products must be the same in a chemical reaction.
This suggests that no amount of matter is lost during a chemical reaction.
The reaction above is a combination reaction in which two species combines to give a product.
To balance chemical reactions, we can simply inspect and assign the appropriate coefficient to the reactants and products. The coefficients should be whole numbers.
Also, the approach here would be mathematical where we would derive simple and solvable algebraic expressions to address the problem.
Assign alphabets a, b and c to the species;
aLi + bBr₂ → cLiBr
Conserving Li; a = c
Br; 2b = c
let b = 1;
c = 2
a = 2
The coefficients are 2, 1 and 2
The balanced equation is:
2Li + Br₂ → 2LiBr

Answer:
1.584e10 = 15,840,000,000,000
Explanation:
250,000 miles
multiply the length value by 63360
25e4 x 63360
= 1.584e10
<span>The correct answer is, Alkali Metals</span>
Yes you balanced it correctly : CH₃CH₂CH₃ ₍g₎ + 5O₂ ₍g₎ -------> 3CO₂ ₍g₎ + 4H₂O ₍g₎
A hack to checking if its correct when they give you the structural formula of one of the species (CH₃CH₂CH₃) is to convert it to the molecular formula and if you get the same answer then it's correct.
So CH₃CH₂CH₃ is the struct-formula for the molec-formula C₃H₈
C₃H₈ + 5O₂ --------> 3 CO₂ + 4H₂O (which means your correct =D)
