There are about 7 or 8 primary tectonic plates. The lithosphere is made of about a dozen plates. The plates fit together like the pieces of a jigsaw puzzle. However, the plates can move. This causes earthquakes, volcanoes, and mountains to form.
Hope it helps
Answer:
The equation is: CuCO3(s) → CuO(s) + CO2(g)
Explanation:
Copper carbonate decomposes at high temperatures, generating the products carbon dioxide (CO2) and copper oxide (II) CuO. In this type of decomposition reaction, a substance is broken generating two different compounds.
Answer:
All of the above
Explanation:
All of this is in the solar system.
Molarity of solution is mathematically expressed as,
M =
![\frac{x\text{weight of solute(g)}}{\text{Molecular weight X Volume of solution(l)}}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5Ctext%7Bweight%20of%20solute%28g%29%7D%7D%7B%5Ctext%7BMolecular%20weight%20X%20Volume%20of%20solution%28l%29%7D%7D%20)
We know that volume = mass/density
Given: mass of solution = 100 g, Density = 1.34 g/ml
∴ volume = 100/1.34 = 88.49 ml = 0.08849 l
Also, we know that molecular weight of sucrose = 342.3 g/mol
∴M =
![\frac{x\text{211.4}}{\text{342.3 X 0.08849}}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5Ctext%7B211.4%7D%7D%7B%5Ctext%7B342.3%20X%200.08849%7D%7D%20)
= 6.979 M
Thus, molarity of solution is 6.979 M
