How does Earth's rotation affect ocean currents?
Lesson 2.09
Question 9 options:
It causes them to flow in a curved path
It has no affect
It causes them to flow from east to west
It causes them to flow from north to south
Answer:
Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.
Explanation:
Earth's rotation affect ocean currents because: A. It causes them to flow in a curved path.
What is Earth rotation?Earth rotation can be defined as the amount of time that is taken by planet Earth to complete its spinning movement about an orbital axis.
This ultimately implies that, Earth rotation refers to the time taken by earth to rotate once on its axis. Also, a spinning movement of the Earth on its axis takes approximately 24 hours to complete with respect to the Sun and it result in an effect called Coriolis.
In conclusion, Earth's rotation affect ocean currents because it causes them to flow in a curved path due to Coriolis effect.

Electrons act like a glue to hold the nucleus together
Answer
Electrons live inside the nucleus and carry a neutral charge.
Explanation:
if I have a +2 oxidation number do I give up or accept electrons?
Answer:
I will give up the electrons
Explanation:
Consider the following rules:
1. An atom loses electrons if its oxidation number is positive.
2. An atom gains electrons if its oxidation number is negative.
3. An atom neither gains nor loses electrons if its atomic number is zero.
As I have an oxidation number [tex]+2[/tex] that is oxidation number is positive, so, I will give up electrons.

2.7 x 10-2 grams of Pb(C2H302)4 are dissolved to make 3.5 mL of
solution. What is the molarity?
Your Answer
Answer:
The molarity is 0.0174 [tex]\frac{moles}{liter}[/tex]
Explanation:
Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.
[tex]Molarity=\frac{number of moles of solute}{volume of solution}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case, being the molar mass of compound Pb(C₂H₃O₂)₄ equal to 443.38 g / mol, then the following rule of three can be applied: if 443.38 grams are contained in 1 mol, 2.7*10⁻² grams in how many moles they are present?
[tex]amount of moles=\frac{2.7*10^{-2} grams*1 mol}{443.38 grams}[/tex]
amount of moles= 6.09*10⁻⁵ moles
Being 1,000 mL= 1 L, then 3.5 mL= 3.5*10⁻³ L
So:
[tex]Molarity=\frac{6.09*10^{-5} moles}{3.5*10^{-3} L}[/tex]
Solving:
Molarity=0.0174 [tex]\frac{moles}{liter}[/tex]
The molarity is 0.0174 [tex]\frac{moles}{liter}[/tex]

Which statement can be applied to an atom of neon?
A The atom has the same electron arrangement as Cl– ion.
B The atom has two more electrons than an atom of oxygen.
C The atom has the same number of outer electrons as an atom of helium.
D The atom has the same number of electrons as a Ca2+ ion.
Answer:
B. The atom has two more electrons than an atom of oxygen.
Explanation:
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.
This ultimately implies that, an [tex] O^{2-} [/tex] atom contains the same number of electrons as an atom of neon.
Hence, a neon atom has two more electrons than an atom of oxygen.
Additionally, Neon is used in lighting advertising displays.

What other substance (besides salt) could you sprinkle over ice to affect how fast it melts? Describe how you would test the substance's impact on the melting time of ice. Predict the results of such a test.
Answer:
See explanation
Explanation:
Salt makes ice to melt faster than it usual. Sugar is another substance that influences the melting time of ice.
If i have a sample of pure ice and another sample of ice treated with sugar. I have to maintain the both initially at 0 degrees temperature and have a stop clock to measure the melting time.
I will ultimately notice that the sample of ice treated with sugar will melt faster than the pure sample of ice due to the presence of an impurity.
2C3H7OH + 9O2 -> 6CO2 + 8H2O
How Many Moles of CO2 can be produced by reacting 6 moles of C3H7OH with oxygen?
Answer:
Up to [tex]18\; \rm mol[/tex] [tex]\rm CO_2[/tex].
Explanation:
The equation for this reaction: [tex]2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O[/tex] is indeed balanced.
Notice that the coefficient of [tex]\rm C_3 H_7 OH[/tex] is [tex]2[/tex] while that of [tex]\rm CO_2[/tex] is [tex]6[/tex].
Therefore, each unit of this reaction would consume [tex]2[/tex] units of [tex]\rm C_3H_7OH[/tex] while producing [tex]6[/tex] units of [tex]\rm CO_2[/tex]. In other words, this reaction would produce three times as much [tex]\rm CO_2\![/tex] as it consumes [tex]\rm C_3H_7OH\![/tex].
If all that [tex]6\; \rm mol[/tex] of [tex]\rm C_3H_7OH[/tex] molecules are actually consumed through this reaction, three times as many [tex]\rm CO_2[/tex] molecules would be produced. That corresponds to [tex]3 \times 6\; \rm mol = 18\; \rm mol[/tex] of [tex]\rm CO_2\![/tex] molecules.

How many electrons are being shared between the two carbon atoms in the covalent compound ethyne? Ethyne has the structure: H−C≡C−H
Answer:
Three lines between the carbon atoms in the Lewis structure represent three covalent bonds. Each covalent bond is a shared pair of electrons, hence there are six electrons being shared between the carbon atoms in ethyne.
The number of electrons that are being shared between the two carbon atoms in the covalent compound ethyne is six.
What are covalent bonds?Covalent bond are formed by the sharing of electrons between two atoms.
In ethyne molecule two carbon atoms are present and between two carbon atoms three covalent bonds are present. And each covalent bond is formed by the sharing of two electrons. So three covalent bonds are formed by the sharing of 6 electrons.
Hence in ethyne 6 electrons are being shared.

why would a pregnant mother need more calcium than a woman her age that is not pregnant?
Besides building teeth and bones, calcium also keeps your blood and muscles moving and helps your nerves send messages from your brain to the rest of your body. Your body can't make calcium, so you need to get it from food or supplements. While you're pregnant, try to get at least 1,000 mg of calcium every day.
Calcium is a vital mineral. Your body uses it to build strong bones and teeth. calcium is also needed for your heart and other muscles to function properly
