What mass of HBO2 is produced from the combustion of 139.5 g of B2H6? Answer in units of g.

aliina [53]

Answer:

$m_{HBO_2}=441.8gHBO_2$

Explanation:

Hello there!

In this case, since the combustion of B2H6 is:

$B_2H_6+3O_2\rightarrow 2HBO_2+2H_2O$

Thus, since there is 1:2 mole ratio between the reactant and product, the produced grams of the latter is:

$m_{HBO_2}=139.5gB_2H_6*\frac{1molB_2H_6}{27.67gB_2H_6} *\frac{2molHBO_2}{1molB_2H_6} *\frac{43.82gHBO_2}{1molHBO_2}$

$m_{HBO_2}=441.8gHBO_2$

Best regards!

What is the mass of the hydrogen atoms in 1 mole of water

Katen [24]

Answer:

2.0158 grams

Explantion:

We are to find the mass of the hydrogen atoms in 1 mole of water.

We know that the formula of water is: $H_2O$

We can see, from the above mentioned formula, that water has 2 hydrpgen atoms.

From the periodic table, we get to know that Hydrogen has an atomic mass of 1.00794 grams.

As there are 2 atoms of hydrogen in water so $2 \times 1.00794 = 2.0158$ grams is the answer

5. What could you do to convert from meters to centimeters? *

maria [59]

centi- is essentially 10^2 of one meter.

If you had 100m, multiplying 100 by 10^2 (or 100) would give you 10000 cm.
