Answer:
From becoming magma. It comes to the surface because of the tectonic plates shifting, it's able to escape from the cracks. it also may cause the plates to melt and allow the magma to rise.
Explanation:
deep underground, rocks are put under tons of pressure and extremely hot temperatures, causing them to melt into magma. sometimes the magma cools and becomes igneous rock. Magma makes it to the surface by either escaping through cracks in tectonic plates or by melting the plates and rising.
Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules<span> of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅</span>6.022<span>⋅1023molec.1mole H2O =1.635⋅1024molec.</span>
Answer:
28g
Solution. Hence, 2 moles of nitrogen atoms weigh 28g.
The reaction produces 2.93 g H₂.
M_r: 133.34 2.016
2Al + 6HCl → 2AlCl₃ + 3H₂
<em>Moles of AlCl₃</em> = 129 g AlCl₃ × (1 mol AlCl₃/133.34 g AlCl₃) = 0.9675 mol AlCl₃
<em>Moles of H₂</em> = 0.9675 mol AlCl₃ × (3 mol H₂/2 mol AlCl₃) = 1.451 mol H₂
<em>Mass of H₂</em> = 1.451 mol H₂ × (2.016 g H₂/1 mol H₂) = 2.93 g H₂
