Answer:
14.2 grams
Explanation:
When converting from number of atoms to grams, first convert it to moles by dividing by 6.022*10^23. Then multiply by the molar mass of the element (Lithium)
Hope this helps!

Answer:
B.
Explanation:
The unit for rate is M/s while the unit for each molecule should be M. You can find the unit for k by putting the units for rate and the molecules into the equation
rate= k{X][Y]
M/s= k * *
k= (M/s) / ()
k=
You can also use this predetermined formula to solve this problem faster: k=
Where n is the number of molecule. There are 3 molecule(2X and 1Y) so n=3, so
k=
k= = =
Answer:
WHY: You can abbreviate an element's electron configuration using the noble gas notation method because when you get down to the lower elements, specifically the d's and the f's, the electron configuration will be very long. The noble gas notation method is a faster answer while also being correct.
HOW: We can abbreviate an element's electron configuration by finding the last noble gas a specific element passed, for example calcium would have just passed Argon. Once you have the "address" of the previous noble gas, then you add on the difference between the element chosen and the noble gas, for example calcium would be [Ar] 4s^2.

Answer:
90g
Explanation:
We need to find the molar mass of C6H12O6. This is done below:
MM of C6H12O6 = (12x6) + (12x1) + (6x16) = 72 + 12 + 96 = 180g/mol
From the question, we obtained:
Volume = 1L
Molarity = 0.5M
Number of mole = Molarity x Volume
Number of mole = 0.5 x 1 = 0.5mol
Mass conc of C6H12O6 = number of mole x MM = 0.5 x 180 = 90g
An alternative method by which we can overcome this global issue is by harnessing Solar energy.
Discussion:
Fossil fuels cause environmental pollution. This is because they are organic compounds and on combustion, they release air pollutants such as, Carbon monoxide.
As a panacea, the use of solar panels for harnessing Solar energy in a bid to replace energy from fossil fuels will prove to be am effective method by which we can overcome the global issue of pollution caused by burning of fossil fuels.
Solar energy is a clean source of energy as there's no release of harmful air pollutants.
