Maple syrup, which comes from the sap of maple trees, contains water and natural sugars. It's a clear, brown liquid and the sugars can’t be separated by filtration. It should be categorized as a homogeneous mixture since the sugar is homogeneously dispersed<span> or mixed in water. It is completely dissolved resulting to uniform properties of the mixture.</span>

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

Compare to the sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure.
Molodets [167]

Here we have to compare the state of helium gas at STP and high temperature and low pressure.

At STP (standard condition of temperature and pressure) i.e. 273K temperature and 1 bar pressure. At STP helium gas will behave as a real gas.

At higher temperature and low pressure Helium will behave as an ideal gas.

The ideal gas conditions are developed on taking into account two factors: (i) the gas molecules are point of mass and having no volume. (ii) there is no existence of force of attraction between the molecules.

The deviation from ideal gas to the real gas depends upon the van der waals' interaction between the gas molecules. Now in low pressure and high temperature, we can ignore the volume and also the inter-molecular force of attraction. Thus the gas sample can behaved as ideal gas.

But at elevated pressure and low temperature i.e. STP the assumptions are not valid and it will behave as real gas.

4.50 g of NaCl reacts with 10.00 g of AgNO3 to produce 7.93 g of AgCl. If the theoretical amount of AgCl that can be formed is 8
olga nikolaevna [1]

Answer: 94.07%

Explanation:

Percentage yield can be calculated by the formula

%yield = Experimental yield/Theoretical yield x100

Experimental yield = 7.93g

Theoretical yield = 8.43

%yield = Experimental yield/Theoretical yield x100

%yield = 7.93/8.43 x 100 = 94.07%
