The oxidation number of oxygen in the carbonate ion found in malachite would be -2.
Answer:
60.9 Kelvin
Explanation: First, write out everything that you know. You are tring to find the temperature, so the temperature will be represented by x.
Pressure (P)= 4.5 atm
Volume (V)= 3L
Number of Moles (n)= ?
Gas Consant (R)= 0.0821, if the pressure is in atm, that means r is 0.0821
Temperature (T)= x
We don't have all the information we need to plug the values into the equation. We still need to know how many moles 55.0 grans of neon is.
Ne in Grams= 55
Atomic Mass of Ne= 20.1797
55/20.1797= 2.7
moles= 2.7
Now that we have all the information we need, plug everying into the equation. In case you don't know, the Ideal Gas Law Equation is PV= nRT.
(4.5)(3) = (2.7)(0.821)x
x= 60.9
Now you have your temperature! It is 60.9 in Kelvin.
A; Town A will be cooler than Town B because it is located near the peak of the mountain.
i believe is the correct answer
Answer:
7.52 × 10⁻¹⁴ mi
Explanation:
Step 1: Given data
Bond length between two carbon atoms (l): 121 pm
Step 2: Convert "l" to meters
We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.
121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m
Step 3: Convert "l" to miles
We will use the conversion factor 1.00 mi = 1609.34 m.
1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi
