Ocean water is salty. There are many type of salts (ionic compounds), but the salt that causes most of the saltiness in ocean water is sodium chloride (NaCl). (This is the same chemical as the table salt in your salt shaker.)
Use the concept of polarity to describe in detail how sodium chloride (NaCl) dissolves in ocean water.
Answer:
H2O is a polar molecule
the H is slightly positive and the O is slightly negative so the Na is attracted to the O side of the water molecule and the Cl is attracted to the H side of the water molecule
Explanation:
A 0.50 M solution of H Br is to be poured into a beaker that initially contains 50 g of solid CaCO3. Determine the volume of H Br that will be needed to completely react with the 50 g of solid CaCO3.
Answer:
2 liters of HBr is needed to completely react with the 50 g of salt.
Explanation:
First of all, we determine the reaction:
2HBr + CaCO₃ → CaBr₂ + CO₂ + H₂O
We need to calculate, moles of carbonate in order to state the stoichiometry (1:2)
50 g . 1mol / 100.08g = 0.499 mol
1 mol of salt need 2 moles of acid to react, according to stoichiometry
Then, 0.499 moles of salt, will react with (0.499 . 2)/1 = 0.999 moles
As we have the [HBr], we can calculate the volume.
M = mol/L → we replace → 0.50 mol/L = 0.999 mol /L
L = 0.999 mol/0.50 mol → 1.99 L ≅ 2L
Think of the different types of reactions you have learned about. How can you tell if they absorb energy or release energy, and at the molecular level, how are they different?
Answer:
Absorbed will be harder to spot than releasing because take this as it's like a tire. A tire will go smaller when it has no air compared to when it has air. But absorbed it the opposite. It gets bigger with more air and etc.

Write about similarities and the differences of the plant and animal cell
Answer:
Mark me as brainliest pls
Explanation:
similarities: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal element
differences: A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.
A 0.25 mol sample of neon gas at 18 °C and 0.799
atm is heated to 49 °C. The new gas pressure is 1.11
atm. What is the change in volume of the neon gas?
Answer: The change in volume is 1.52 L
Explanation:
According to ideal gas equation:
[tex]PV=nRT[/tex]
P = pressure of gas = 0.96 atm
V = Volume of gas = ?
n = number of moles
R = gas constant =[tex]0.0821Latm/Kmol[/tex]
T =temperature =[tex]18^0C=(18+273)K=291K[/tex]
[tex]V=\frac{nRT}{P}[/tex]
[tex]V=\frac{0.25mol\times 0.0820 L atm/K mol\times 291K}{0.799atm}=7.47L[/tex]
The combined gas equation is,
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 0.799 atm
[tex]P_2[/tex] = final pressure of gas = 1.11 atm
[tex]V_1[/tex] = initial volume of gas = 7.47 L
[tex]V_2[/tex] = final volume of gas = ?
[tex]T_1[/tex] = initial temperature of gas = [tex]18^0C=(18+273)K=291K[/tex]
[tex]T_2[/tex] = final temperature of gas = [tex]49^0C=(49+273)K=322K[/tex]
Now put all the given values in the above equation, we get:
[tex]\frac{0.799\times 7.47}{291}=\frac{1.11\times V_2}{322}[/tex]
[tex]V_2=5.95L[/tex]
The change in volume = (7.47 - 5.95)L=1.52 L
The space occupied by the substance, solution or particle in a system is called volume. The change in volume of the neon gas is 1.52 L.
What is the ideal gas equation?The ideal gas equation is the equation that states the relation between the pressure, volume, temperature, moles and gas constant of the hypothetical gas.
The ideal gas equation of a hypothetical ideal gas can be given as,
[tex]\rm PV = nRT[/tex]
Where,
Pressure (P) of the gas = 0.96 atmThe volume of the gas = VNumber of moles (n) = 0.25 molGas constant (R) = 0.0821 Latm/ KmolTemperature (T) = 291 KFrom the above equation volume can be calculated as,
[tex]\begin{aligned} \rm V &= \rm \dfrac{nRT}{P}\\\\&= \dfrac{0.25 \times 0.0820 \times 291}{0.799}\\\\&= 7.47 \;\rm L\end{aligned}[/tex]
The combined gas equation can be shown as,
[tex]\rm \dfrac{P_{1}V_{1}}{T_{1}} = \dfrac{P_{2}V_{2}}{T_{2}}[/tex]
Where,
The initial pressure of the gas [tex]\rm (P_{1})[/tex] = 0.799 atmThe final pressure of the gas [tex]\rm (P_{2})[/tex] = 1.11 atmThe initial volume of gas [tex]\rm (V_{1})[/tex] = 7.47 LThe final volume of gas [tex]\rm (V_{2})[/tex] = ?The initial temperature of the gas [tex]\rm (T_{1})[/tex] = 291 KThe final temperature of the gas [tex]\rm (T_{2})[/tex] = 322 KSubstituting values in the above equation:
[tex]\begin{aligned}\dfrac{0.799 \times 7.47}{291} &= \rm \dfrac{1.11 \times V_{2}}{322}\\\\&= 5.95 \;\rm L\end{aligned}[/tex]
Volume change of the gas is, [tex](7.47 - 5.95)\;\rm L = 1.52\;\rm L[/tex]
Therefore the change in the volume of the neon gas is 1.52 L.

Explanation:
A catalyst of copper mixed with zinc oxide and alumina is used in industry for this production of methanol. Explain the function of the catalyst.
Answer:Copper oxide + Hydrogen → Copper + Water
Copper sulfate + Zinc → Zinc sulfate + copper
Aluminium + Copper chloride → Aluminium chloride + copper
Copper + Oxygen → Copper oxide
Explanation:
Chemical reactions involves chemical combination of compounds or elements as reactants to form other compounds or elements.
In this case, various reactants given will react exhibiting different types of chemical reactions to form products.
First reaction
Aluminium + Copper chloride → Aluminium chloride + Copper
This is a single displacement reaction in which aluminium which is a more reactive element than copper displaces copper from its salt.
Second reaction
Copper oxide + Hydrogen → Copper + water
It is another example of a single replacement reaction. Hydrogen displaces less reactive metals from their oxide to form water and the metal.
Third reaction
Copper sulfate + Zinc → Zinc sulfate + copper
It is another single replacement reaction.
Zinc is more reactive than copper and therefore replaces copper from its salt solution.
Fourth reaction
Copper + Oxygen → Copper oxide
It is a synthesis reaction.
A synthesis reaction is a reaction in which elements or small compounds combine to form single compound.

A plane takes 230 passengers from New York to Chicago in 3 hours.
New York and Chicago are 789 miles away from each other. What is the
average speed of the flight in mph?
Answer:263mph
Explanation:
The average speed of the flight in mph is 263 miles per hour.
What is speed?In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval,the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity.
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). The average speed is calculated as, distance/time =789/3=263 miles per hour.
