How do you balance the equation Hydrogen plus Oxygen yield water?
Andre45 [30]
Hey there! Hello!

Not sure if you still need the answer to this question, but I'd love to help out if you do. 

So, the way to balance this equation is pretty simple. First, you need to keep in mind that molecules of hydrogen and oxygen do not come in single molecules, but in bonded pairs, represented by H2 and O2. 

H2+O2=H2O

But, that's incorrect. The combination of 2 hydrogen molecules with 1 oxygen molecule yields water, but that leaves one oxygen molecule leftover. When broken down, this is how many of each molecule is on each side of the previously stated equation:

Left:
H: 2
O: 2

Right:
H: 2
O: 1

So we have to multiply H2O on the right side by 2 in order to get this:

H2+O2=2(H2O)

Left: 
H: 2
O: 2

Right: 
H: 4
O: 2

The last step is to multiply H2 on the left by two to make it match up with the right side, balancing the equation:

2(H2)+O2=2(H2O)

Left: 
H: 4
O: 2

Right: 
H: 4
O: 2

That makes our equation balanced! I hope this helped you out, feel free to ask any additional questions if you need further clarification. :-)

Answer:

В.  No, because the mass of the reactants is less than the mass of the products.

Explanation:

Chemical equation:

NaBr + Cl₂      →      2NaCl + Br₂

The given equation is not balanced because number of moles of sodium and bromine atoms are less on reactant side while more on the product side.

There are one mole of sodium and one mole of bromine atom on left side of equation while on right side there are 2 moles of bromine and 2 moles of sodium atom are present. The number of moles of chlorine atoms are balanced.

Balanced chemical equation:

2NaBr + Cl₂      →      2NaCl + Br₂

Now equation is balanced. Number of moles of sodium , chlorine and bromine atoms are equal on both side.

Which is smallest to biggest glucose,starch,protein,carbon,water,amino,oxygen
likoan [24]

Answer:

Smallest to biggest order is as follows.

C < O < Amino < Water < Glucose < Starch < protein.

Explanation:

The given atoms or molecules and their atomic masses is as follows.

Glucose - C_{6}H_{12}O_{6} - 180 g/mol

Starch - C_{27}H_{48}O_{20}- 692.7 g/mol

Protein - R-CH(NH_{2})COOH - it is vary for different proteins.

Carbon - C - 12 g/mol

Water - H_{2}O- 18 g/mol

Amino - NH_{3}- 17 g/mol

Oxygen - O - 16 g/mol

Increase the molar mass increases size of the molecules.

Therefore, Smallest to biggest order is as follows.

C < O < Amino < Water < Glucose < Starch < protein.
