Troposphere, this is the layer of the atmosphere closest to the earths crust.
Answer:
1
Explanation:
I would say 1 because that configuration has 7 valence electrons. The goal of the atom is to gain a full octet so it just needs to gain 1 more electron to get the full octet. To get the one electron to fill the valence shell it would only need to have 1 covalent bond.
I hope this helps. Let me know if anything is unclear.
Volume = ?
Molarity (M) = 1.00 x 10⁻² M
moles (n) = 3.00 x 10⁻¹ mol
V = n / M
V = 3.00 x 10⁻¹ / 1.00 x 10⁻²
V = 30 L
<h3>
Answer:</h3>
Concentration will be 0.1 M and not 0.050M
<h3>
Explanation:</h3>
This explains why the molarity is not 0.050 M but 0.1 M
Molarity is the concentration of a solution in moles per liter.
Therefore,
Molarity = moles ÷ Volume
In this case,
We have 1.34 g of CuCl₂ and a volume of 100 mL
To get the molarity we need to find the number of moles in 1.34 CuCl₂
Number of moles = Mass÷ molar mass
Molar mass of CuCl₂ = 134.45 g/mol
Therefore,
Moles of CuCl₂ = 1.34 g ÷ 134.45 g/mol
= 0.009965 moles
= 0.01 moles
Then we can calculate the molarity;
Molarity = Number of moles ÷ Volume
Volume of the solution is 100 mL or 0.1 L
Molarity = 0.01 moles ÷ 0.1 L
= 0.1 M
Therefore, the concentration of 1.34 g CuCl₂ in a volume of 100 mL is 0.1 M and not 0.050M.
Answer : The temperature on the Fahrenheit scale was, 
Explanation :
The conversion used for the temperature from degree centigrade to Fahrenheit is:
where,
= temperature in Fahrenheit
= temperature in centigrade
As we are given the temperature in degree centigrade is, 45
Now we have to determine the temperature in Fahrenheit.
Therefore, the temperature on the Fahrenheit scale was,
