Answer:
Large wheel.
Explanation:
It would be easier for the captain to turn a large wheel as compared to a small wheel because less amount of effort is needed by the captain to turn the rudder. If a steering wheel is small, more effort and force is required to turn it while on the other hand, if the steering wheel is large, small effort is needed to turn the rudder. The large size of a sailing boat's steering wheel can help the captain to have more control over the boat as compared to small steering wheel and he is able to access it from either side of the boat.
when an atom become a negative ion, where do the extra electrons come from?
Answer:
Valence Shell
Explanation:
Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons.

Are two atoms of same element identical
Answer:
No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
Answer: No
Explanation: Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.

How do I do unabbreviated electron configurations?
Answer:
In shorthand electron configuration, the electron configuration starts with the symbol of the noble gas in the previous period, followed by the additional configuration of the electrons for the given element. For example, aluminum has the atomic number 13, which is the number of protons in the nuclei of its atoms.
if you need more help go to you-tube and search up Abbreviated Electron Configurations and it's by EisleyChem

. Which situation will result in lower average kinetic energy? a) 100 people go swimming into a NYC public pool b) 100 people go swimming at Coney Island beach
Answer:
I think it would be the beach because all the waves and such but in a pool with more people there is a tight space so they cant move around as much and as freely. But this could be a trickster question but I would choose the beach.
Hope this is right :)

10. A balloon is blown up to a volume of 18 L at a pressure of 1.0 atm and
298 K. What would the pressure inside the balloon be when its volume
becomes 4.0 L and its temperature is 239 K?*
Answer:
3.6 atm
Explanation:
10. A balloon is blown up to a volume of 18 L at a pressure of 1.0 atm and
298 K. What would the pressure inside the balloon be when its volume
becomes 4.0 L and its temperature is 239 K?*
PV/T = P'V'/T'
(18 X 1)/298 =(P' X 4)/239
so
P' = (18 X 239)/(298 X 4)= 3.6 atm
P'=(18 X 239)/(298 x 4) =

Fluorine + sodium chloride → sodium fluoride + __________. What is the missing chemical name?
Answer:
Chlorine (Cl)
Explanation:
The equation would be:
[tex]F+NaCl[/tex] → [tex]NaF + Cl[/tex]
This is because no atom is lost in a reaction. Chlorine would be the missing chemical as it is on the other side of the equation and needs to be accounted for on the products side.
The missing chemical in the reaction of sodium chloride with fluorine forming sodium fluoride is chlorine.
What is a chemical equation?The chemical equation is given as the representation of the reactants molecules and the product molecules in a chemical reaction.
The reaction follows the law of conservation and thereby no element will be lost in the reaction. Thus, the chemical reaction for the fluorine and sodium chloride is given as:
Fluorine + Sodium chloride → Sodium fluoride + Chlorine
Thus, the missing chemical in the reaction was chlorine.

Most lakes have rivers flowing out of them, carrying water to the ocean. However, some
lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into
these lakes leaves only through evaporation. Considering that the water flowing into the
lakes contains many dissolved substances, how does the lack of an outlet affect the
composition of these lakes? What would you expect to happen after many more years
of inflow and evaporation?
Answer:
I feel like it could lead to flooding

na+F2-> naF a chemical reaction. the synthesis of sodium fluoride noF is shown above all chemical reactions involve a change to an atoms number of protons neutrons electrons
Answer: Electrons
Explanation:
A chemical reaction usually only affects elctrons. A chemical reaction usually results in the electrons being transferred or shared. When sodium and fluorine react to produce sodium fluoride, a sodium electron is transferred to the fluorine to produce ionic bonds. This ionic bond exists between the sodium cation and fluoride (fluorine) anion.
