A student heats 10.52 g of sodium hydrogen carbonate in a crucible until the compound completely decomposes to sodium carbonate

saveliy_v [14]

Answer:

$m_{Na_2CO_3}^{theoretical}=6.636gNa_2CO_3$

Explanation:

Hello!

In this case, since the decomposition of sodium hydrogen carbonate is:

$2NaHCO_3(s)\rightarrow Na_2CO_3(s)+H_2O(g)+CO_2(g)$

Thus, since there is a 2:1 mole ratio between the sodium hydrogen carbonate and sodium carbonate, and the molar masses are 84.01 and 105.99 g/mol respectively, we obtain the following theoretical yield:

$m_{Na_2CO_3}^{theoretical}=10.52gNaHCO_3*\frac{1molNaHCO_3}{84.01gNaHCO_3}*\frac{1molNa_2CO_3}{2molNaHCO_3} *\frac{105.99gNa_2CO_3}{1molNa_2CO_3}\\\\ m_{Na_2CO_3}^{theoretical}=6.636gNa_2CO_3$

Best regards!

A hydrogen atom has a diameter of about 10 nm. Express this diameter in micrometers, meters, and millimeters.

MariettaO [177]

1) 1 nm = 0.001 µm; one nanometer is equal to 0.001 (10⁻³) micrometer.

d(H) = 10 nm; diameter of hydrogen atom.

d(H) = 10 nm · 0.001 µm/nm.

d(H) = 0.01 µm = 10⁻² µm.

2) 1 nm = 10⁻⁹ m ; one meter is equal to 0.0000000001 (10⁻⁹) meter.

d(H) = 10 nm.

d(H) = 10 nm · 10⁻⁹ m/nm.

d(H) = 0.00000001 m = 10⁻⁸ m.

3) 1 nm = 10⁻⁶ mm ; one nanometer is equal to 0.000001 (10⁻⁶) millimeter.

d(H) = 10 nm · 10⁻⁶ mm/nm.

d(H) = 0.00001 mm = 10⁻⁵ mm.
