Period
Group
Explanation:
On the periodic table the numbers 1,2 and 3 can represent either groups or periods.
The periodic table gives the arrangement of elements based on their atomic numbers
- They are divided into vertical columns and horizontal rows
- The vertical columns are the groups whereas the horizontal rows are the periods.
- The vertical columns are made up of elements having the same number of electrons in their outermost shell.
- The horizontal columns are made up of elements having the same number of shell.
- On the periodic table, the groups are numbered 1 - 18
- There are 7 periods on the table.

Answer:
See Explanation
Explanation:
Resonance is a valence bond terminology which is used to describe a situation in which a single structure is not able to fully describe the nature of bonding in a molecule.
In such cases, we invoke more than one structure. Each structure contributes significantly to our understanding of the nature of bonding in the molecule under consideration and these structures are called canonical or resonance structures.
The real structure of the molecule is somewhere in between these structures - a resonance hybrid.
For ozone, two equivalent structures can be used to describe the bonding in the molecule. These structures are equivalent as shown in the mage attached. We can see from these structures that the bond order in ozone is 1.5(one and half bonds)

The molecular formula for the combustion of butane in oxygen is:
2 C4H10 + 13 O2 ---> 8 CO2 + 10 H20
<span>You take the mass of carbon dioxide, 56.8g, divide by its molar mass, 44.01g/mol, to produce the moles of carbon dioxide. This is multiplied by the molar ratio of butane/CO2, (2/8) = 1/4, which gives the moles of butane required to produce the carbon dioxide. Multiply the number of moles of butane by its molar mass, 58.12g/mol, to produce the mass of butane. Mass of butane = 18.8g</span>
The three concerns that the residents of this area might be:
1) <span>The cost of not moving forward is extremely high, so they opposed the plan, as they think it would affect US economy
2) </span><span>Nuclear waste disposal capability is an environmental imperative, so their environment would be polluted by very radioactive materials.
3) </span>Demand for new nuclear plants also demands disposal capability which supports national security but again, their site will be no longer for them. But unfortunately, <span>Extensive studies consistently show Yucca Mountain to be a sound site for nuclear waste disposal so the plan can't be abolished.
Hope this helps!</span>
Answer:
1520 mmHg
Explanation:
Let's solve this by a factor conversion:
1 atm → 760 mmHg
2 atm . 760 mmHg / 1 atm = 1520 mmHg
