Answer:
9 moles of NaNO3 is obtained
Explanation:
The balanced chemical reaction equation for the reaction is;
Al(NO3)3 + 3NaCl-------> 3NaNO3 + AlCl3
Now, we have to determine the limiting reactant. The limiting reactant yields the least amount of NaNO3.
1 mole of Al(NO3)3 yields 3 moles of NaNO3
4 moles of Al(NO3)3 yields 4 * 3/1 = 12 moles of NaNO3
Also,
3 moles of NaCl yields 3 moles of NaNO3
9 moles of NaCl yields 9 * 3/3 = 9 moles of NaNO3
Hence, NaCl is the limiting reactant and 9 moles of NaNO3 is obtained.
Answer:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

Answer:
it could be 25degrees c... not sure
Answer:
75% will have long legs and 25% will have short legs
Explanation:
Answer: c = 0.39 cal/g°C or
1.63 J/g°C
Explanation: To find the specific heat of the metal we will use the formula of heat which is Q= mc∆T.
We will derive for c, c = Q / m∆T
25.0 cal/ 4.0 g ( 36°C - 20°C)
= 0.39 cal / g°C
Or we can convert calories to joules.
0.39 cal x 4.184 J/ 1 cal
= 1.63 J /g°C
