How much positive charge is in 1.4 kg of oxygen? The atomic weight (15.9994 g) of oxygen contains Avogadro’s number of atoms, wi
Cerrena [4.2K]

Answer:

6.7511\times 10^7\ C

Explanation:

The atomic weight of oxygen = 15.9994 g

This mass corresponds to 1 mole of the oxygen atoms.

Thus,

15.9994 g mass of oxygen contains 6.02\times 10^{23} atoms of oxygen.

1.4 kg = 1400 g ( 1 kg = 1000 g)

So,

1400 g mass of oxygen contains \frac {6.02\times 10^{23}}{15.9994}\times 1400 atoms of oxygen.

Number of atoms in 1400 g of oxygen = 526.769754\times 10^{23}

Also, 1 atom of oxygen contains 8 protons

Charge of 1 proton = + 1.602\times 10^{-19}\ C

So, Charge on 1 atom of oxygen = 8\times 1.602\times 10^{-19}\ C

Thus,

Charge on 526.769754\times 10^{23} atoms of oxygen = 526.94476\times 10^{23}\times 8\times 1.602\times 10^{-19}\ C=6.7533\times 10^7\ C

Thus, positive charge in 1.4 kg of oxygen = 6.7511\times 10^7\ C

In what main way is separating the components of a mixture different from separating the components of a compound?
Zigmanuir [339]

Explanation:

Compounds are the species in which all the components react chemically to form a molecule which has a different property from the constituting elements.

On the other hand, mixture are the species in which the components do not react chemically and the original properties of the components are not lost.

<u>Thus, separation of the mixture into its components can be done by the physical means while separation of the compound into its components can be only possible by the chemical means.</u>

Rearrange the following equation and solve for x when the hydrogen ion concentration is 0.01 M. pH=4+logx (Recall that pH=−log[H
bezimeni [28]

Answer:

x = 1 x 10⁻²

Explanation:

Since the pH is the same in both cases, the two expressions for pH can be set equal to each other:

pH = 4 + log(x) = -log[H⁺]

The hydrogen ion concentration ([H⁺]) is 0.01 M, so this value can be substituted in the equation:

4 + log(x) = -log(0.01)

4 + log(x) = 2

log(x) = -2

x = 10⁻²
