How much positive charge is in 0.7 kg of lithium? with each atom having 3 protons and 3 electrons. The elemental charge is 1.602
hichkok12 [17]

Explanation:

As a neutral lithium atom contains 3 protons and its elemental charge is given as 1.602 \times 10^{-19} C. Hence, we will calculate its number of moles as follows.

          Moles = \frac{mass}{\text{molar mass}}

                     = \frac{0.7 \times 1000 g}{7 g/mol}

                     = 100 mol

According to mole concept, there are 6.023 \times 10^{23} atoms present in 1 mole. So, in 100 mol we will calculate the number of atoms as follows.

        No. of atoms = 100 \times 6.023 \times 10^{23}

                               = 6.023 \times 10^{25} atoms

Since, it is given that charge on 1 atom is as follows.

                     3 \times 1.602 \times 10^{-19}C

                    = 4.806 \times 10^{-19}C

Therefore, charge present on 6.023 \times 10^{25} atoms will be calculated as follows.

    6.023 \times 10^{25} atoms \times 4.806 \times 10^{-19} C

            28.95 \times 10^{6}C

Thus, we can conclude that a positive charge of 28.95 \times 10^{6}C is in 0.7 kg of lithium.

If measuring experimental results, what can you predict about the work output of a 1200 watt hair dryer? the work output of the
eimsori [14]

Answer: first option, the work output of the hairdryer will be less than the work input.


Explanation:


1) The work output measured in watts is the power of hair dryer measured in joules per second.


2) The hair dryer converts electrical energy from the wall outlet to mechanical and thermal energy: hot wind.


3) Nevertheless, you can never expect a 100% efficiency of the machines: due to friction, some energy is converted into useless energy.


So, efiiviency = power output / power input< 1 ⇒


power output = work output / time


input power = work input / time


⇒ work output / work input < 1


⇒ work output < work input.


Which is the first option: the work output of the hairdryer will be less than the work input
