Explanation:
mass = Moles * molar mass
molar mass of BaSO4 = 112+32+64= 208
= 1.72*208 = 357.76
Hey there!
Si₂H₃ + O₂ → SiO₂ + H₂O
Balance H.
3 on the left, 2 on the right. Add a coefficient of 2 in front of Si₂H₃ and a coefficient of 3 in front of H₂O.
2Si₂H₃ + O₂ → SiO₂ + 3H₂O
Balance Si.
4 on the left, 1 on the right. Add a coefficient of 4 in front of SiO₂.
2Si₂H₃ + O₂ → 4SiO₂ + 3H₂O
Balance O.
2 on the left, 11 on the right. We can't do this by simply adding coefficients to O₂ since 11 isn't divisible by 2. So we need to multiply the coefficients in front of everything else by 2 first.
4Si₂H₃ + O₂ → 8SiO₂ + 6H₂O
Now we can balance O properly.
2 on the left, 22 on the right. Add a coefficient of 11 in front of O₂.
4Si₂H₃ + 11O₂ → 8SiO₂ + 6H₂O
This is our final balanced equation:
4Si₂H₃ + 11O₂ → 8SiO₂ + 6H₂O
This means the coefficient for O₂ when the chemical equation is balanced is 11.
Hope this helps!
Newton's second law of motion can be formally stated as follows:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
This verbal statement can be expressed in equation form as follows:
a = Fnet / m
Answer:
Convection, and boundaries
Explanation:
In this lab, you modeled how plates move. The plates that make up Earth’s lithosphere move because of convection . You also saw how plates interact with each other. The interactions between plates form plate boundaries of which there are three main types.
