Spring scale
It's a tool used to measure force.
2H2O --> 2H2 + O2
The mole H2O:mole O2 ratio is 2:1
Now determine how many moles of O2 are in 50g: 50g × 1mol/32g = 1.56 moles O2
Since 1 mole of O2 was produced for every 2 moles of H2O, we need 2×O2moles = H2O moles
2×1.56 = 3.13 moles H2O
Finally, convert moles to grams for H2O:
3.13moles × 18g/mol = 56.28 g H2O
D) 56.28
solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Answer: 233 L of
will be produced from 150 grams of 
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of
produce = 8 moles of
Thus 2.59 moles of
will produce=
of
Volume of
Thus 233 L of
will be produced from 150 grams of 
Answer:
When you balance a chemical equation you change coefficients.You never change subscripts. A coefficient is a whole number multiplier. To balance a chemical equation you add the coefficients to make sure there are the same number of atoms on each side of the arrow.
