Answer: C10H8 + 12O2 ----> 10CO2 + 4H2O
Explanation:
To balance this, we have to make sure that the same number of atoms exist at both sides (Conservation of energy)
Note:The reaction is exothermic, giving off heat energy.
Left hand side: C= 10,
H=8,
O= 2×12=24
Right hand side: C= 10×1=10,
H= 4×2=8,
O=10×2=20 (for 10CO2) and 4×1=4 (All equal to 24)
With the above analysis, it is clear that numbers had to be added to molecules to get an equal number of atoms for both sides.
Explanation:
Used to separate one reactant or product from another

THANK YOU
Since the equation for density is d=m/v, you can multiply both sides by m in order to get m by itself {d(v)=m}. Plug the volume and density in (1.1x7.9) and you will get 8.69. If you are using proper sig figs, then it will be 8.7g.
Answer: 8.12 g NaCl
Explanation: Use Avogadro's number to find the number of m
moles of NaCl:
8.24x10²² molecules NaCl / 1 mole NaCl/ 6.022x10²³ molecules NaCl
= 0.14 mole NaCl
Next convert moles to grams NaCl using its molar mass;
0.14 mole NaCl x 58g NaCl / 1 mole NaCl
= 8.12 g NaCl
