I need help! how many moles are in 3.4*10^-7 grams of silicon dioxide, SiO2. I got 2.0^17 but I think it's wrong :(

blondinia [14]

Molar mass SiO2 = 28 + 32 = 60

so moles sand = 3.4 x 10-7 / 60

True or false

Kaylis [27]

Answer:

True

Explanation:

Forces, equal in magnitude and opposite in direction, and cancel each other out are called Balanced Forces.

Balanced Forces DO NOT cause any change in the velocity of the object, but the Object may correspond to a change in shape or size.

Example :

Blasting a balloon by compressing it tightly with both hands, roughly with an equal force, is a practical example of Balanced Forces. In this case, the balloon before the burst stays at a state of rest and same after the burst. But the burst or the compression, causes a change in the shape of the balloon.

Answer:

Therefore 373 mole of Al produce 746 mole of water.

Explanation:

Given reaction is

3 Al+3NH₄ClO₄→Al₂O₃+AlCl₃+3NO+6H₂O

From the above reaction it is clear that 3 mole of Al produce 6 mole of water.

Therefore

3 mole of Al produce 6 mole of water.

1 mole of Al produce $\frac{6}{3}$ mole of water.

373 mole of Al produce $\frac{6\times 373}{3}$ mole of water.

= 746 mole of water.

Therefore 373 mole of Al produce 746 mole of water.
