Answer:
nitric acid + iron=iron+[nitric acid ] 2 hydrogen
Answer: This can be quickly solved with "traintracks"
Explanation:
You start w/ grams of water and want to find moles of oxygen gas produced.
So you want to Convert:
Grams of water -> moles of water -> moles of oxygen gas.
The two things you need to know to set up the tracks are:
1)Molar mass of water- H2O
Hydrogen - 1.008(x2)
Oxygen - 16.00
Water - 18.016
Answer:
Horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases.
Step-by-step explanation:
The temperature is constant during a phase change (melting or boiling), so the graph is a horizontal line.
The temperature increases when a single phase (solid, liquid, or gas) is heated, so the graph for these changes has an upward slope.
A is <em>wrong</em>. A horizontal line shows a constant temperature.
B is <em>wrong</em>. There are no vertical lines in a heating curve.
D is <em>wrong.</em> A horizontal line does correspond to an increase in temperature.
Answer:
III, IV, and V
Explanation:
The complex [CO(NH3)6]3+ is a diamagnetic complex. It a low spin d^6 complex. Most d^6 complexes are low spin due to the higher crystal field stabilization energy of the low spin over the high spin arrangement.
d^6 metal complexes are known to be octahedral (a coordination number of 6 leads to octahedral geometry). Octahedral complexes does not have geometric isomers rather, may exist as the fac or her stereo isomers.
