Nitrogen is a non-metal and aluminum is a metal so the bond would be ionic.
Answer:
A) As the phase changes occur, the freedom of motion of the particles increases.
Explanation:
As the phase changes occur, the freedom of motion of the particles increases.
An easy way to do it is to convert the percentage to a decimal, in this case, .32
Then, multiply that by the amount of people.
An equation would be,

Hope this helped :)
Answer:
Explanation:
All the cobalt in the sample is in the precipitate, so you need to determine the amount of cobalt in the precipitate.
<u>1. Calculate the molar mass of CoHg(SCN)₄</u>
Atom Number of atoms Atomic mass Product
g/mol g/mol
Co 1 58.933 58.933
Hg 1 200.59 200.59
S 4 32.065 128.26
C 4 12.011 48.044
N 4 14.007 56.028
=========
Molar mass: 491.855
<u>2. Set a proportion</u>
- 58.933g of Co / 491.855 g of compound = x / 0.1102 g of compound
Clear and compute:
- x = 0.1102 × 58.933 / 491.855 g of Co
Round to four significant figures: 0.01320g of cobalt ← answer
Answer: Hydrocarbon fuels like methane (CH4) burn in the presence of oxygen to produce carbon dioxide and water. This process of combustion releases energy. When energy is released during the course of a chemical reaction, it is said to be an EXOTHERMIC reaction.
