Answer:

m = 4.58 g.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to realize this problem is solved via the ideal gas equation:

PV=nRT

As we can calculate the moles of propane given the pressure, temperature and volume as shown below:

n=\frac{PV}{RT} \\\\n=\frac{1.10atm*2.00L}{0.08206\frac{atm*L}{mol*K}*258K} \\\\n=0.104mol

Finally, since the molar mass of propane is 44.1 g/mol, we calculate the mass by following the shown below mole-mass conversion factor:

m=0.104mol*\frac{44.1g}{1mol}\\\\m= 4.58g

Regards!

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical
Kazeer [188]

Answer:

2H_2O\rightarrow 2H_2+O_2

Explanation:

Hello there!

In this case, for the reaction by which water is decomposed to molecular hydrogen and oxygen:

H_2O\rightarrow H_2+O_2

It is necessary to perform the inspection balance process since there is a dissimilar number of atoms of oxygen on both sides; therefore, by putting a 2 on water we balance oxygen:

2H_2O\rightarrow H_2+O_2

But now, there are four hydrogens on the left; therefore, we put a 2 on hydrogen to finally balance it:

2H_2O\rightarrow 2H_2+O_2

And obviously, the coefficient in oxygen is an unwritten 1.

Best regards!

Why do chemically active metals have low electronegativity values?
sdas [7]
Active metals are those metals in the group 1 of the periodic table.

Electronegativity is the trend to atract electrons.

Active metals have few valence electron, because their last shell is of the kind ns^1 or ns^2

Then, these atoms do not trend to attract electrons. The most electronegative atomos are those who have 7 valence elecfrons; this is their last shell is of the kind ns^7, because when they attract one electron to its valence shell they will complete 8 electrons which is the most stable configuration.
