Answer:
270.34
Explanation:
pressure, 550 pressure, 270.34
______________ = ___________
177 degree celsius. 87 degree celsius.
550 x 87 / 177 = 270.34
Sodium metal is quite reactive; sodium ions (as in NaCl) are quite unreactive. Cl^- ions are not reactive; they are stingily attracted to positive ions such as Na^+with which they form ionic bonds.
C: 12.0107 g/mol ≅ 12.00 g/mol
H: 1.00784 g/mol ≅ 1.008 g/mol
O: 15.999 g/mol ≅ 16.00 g/mol
n(molar mass of CH2O)= 180
n.30=180
n=6
molecular formula: c6h12o6 glucose
The answer is B. Each chlorine has three non-bonded pairs and one bonded pair of electrons.
I just took the test and it was correct! 5/5 :)
Answer:
D — All of them
Explanation:
The activation energy in a reaction is the minimum amount of energy required for a chemical reaction to take place. Since all the options are processes in a chemical reaction, D should be the answer.
