Q. Explain why magnesium
oxide has a much higher
melting point than
sodium chloride.
If you answer this correctly ill mark you as brainliest.
Answer:
Why does Magnesium Oxide have a higher melting point than Sodium Chloride? ... As the charge in the ionic lattice in Magnesium Oxide is two times as large, the ionic bonding is stronger so more energy is required to overcome the electrostatic attraction and break down the ionic lattice.

Explain what happens when salt used for snow causes metallic parts of a car to corrode. What is the process called?
Answer:
Why does a car rust from road salt? Metal parts of a car come in contact with precipitation water containing carbon dioxide and oxygen. Road salt contains free-radical ions and they come into contact with the precipitation water. After extended exposure to oxygen, iron oxide forms, which speeds up the rusting process.

Using an analogy of a water balloon, describe the function of the bladder.
Answer:
A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.
Explanation:
A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.
What is bladder?The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.
As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.
The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.
Thus the function of bladder and water balloon are found to be same.

a ceiling fan's blades collect dust faster than other objects in a room. the constant pushing and rubbing against the air provide a cool breeze for the people in the room. what causes the ceiling fan´s blade to collect dust so quickly.
As the blades rotate, they experience frictional forces as they `rub' against the air; this knocks electrons around, causing the blades to build up a net charge. The charged dust particles then stick to the charged areas of the blades. "The leading edge of the blades usually develops the thickest layer of dust.
To solve this we must be knowing each and every concept related to dust. Therefore, frictional forces allow the ceiling fan´s blade to collect dust so quickly.
What is dust?Dust stirred up by automobiles on the road may account for 33% overall air pollution. Deposits of vehicle or commercial exhaust gas, particles through tire and braking wear, dust from paved streets or potholes, plus dust from building sites all contribute to road dust.
As the blades revolve, frictional forces cause them to 'rub' against the air, knocking electrons around and allowing the blades to accumulate a net charge. The electrified dust particles are subsequently attracted to the charged portions of the blades. Typically, the sharp end of the blades creates the heaviest coating of dust.
Therefore, frictional forces allow the ceiling fan´s blade to collect dust so quickly.

Answer:
D. 1 = gamma; 2 = alpha, 3 = beta
Explanation:
I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)
Hope this is helpful for others! :D
Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.
What are radiations?During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.
Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

What is the function of the outer covering of a plant?
A plant's outer covering is involved in reproduction.
A plant's outer covering helps reduce water loss.
A plant's outer covering is for preying on other plants.
A plant does not have an outer covering.
Answer:b
Explanation:
The function of the outer covering of a plant is to help reduce water loss, option B. The outer covering of a plant is known as the epidermis, and it serves as a protective layer that helps to prevent excessive water loss through transpiration.
What is plant's epidermis ?The epidermis may contain specialized structures such as stomata and trichomes, which further regulate water loss and protect the plant from environmental stresses such as insect predation and UV radiation.
Option A, "A plant's outer covering is involved in reproduction," is incorrect because the reproductive structures of plants are typically located within the plant's interior, not on the outer surface.
Option C, "A plant's outer covering is for preying on other plants," is incorrect because plants are not capable of actively preying on other plants.
Option D, "A plant does not have an outer covering," is incorrect because all plants have an outer covering in the form of the epidermis or a similar structure.
Hence, option B is correct.

Answer: [tex]2Bi(NO_3)_5(aq)+5Sr(OH)_2(aq)\rightarrow 2Bi(OH)_5(s)+5Sr(NO_3)_2(aq)[/tex]
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
[tex]2Bi(NO_3)_5(aq)+5Sr(OH)_2(aq)\rightarrow 2Bi(OH)_5(s)+5Sr(NO_3)_2(aq)[/tex]

Se tiene un litronde solucion de agua con alcohol con una consentracion del 4.5% v/v ¿Cuanto alcohol se tiene en la solución
Answer:
45 mL
Explanation:
Tenemos los siguientes datos:
V = 1 L
C = 4,5% v/v
El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:
4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol
Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:
4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

A solution contains 23 ppm of dissolved oxygen in 242.0066 ml of solution. What is the mass of oxygen?
Answer:
Mass of Oxygen is equal to 0.005566 grams
Explanation:
As we know,
ppm=(grams of solute/grams of solution)*1,000,000
Substituting the given values, we get -
23 ppm = (grams of solute/242.0066 grams)*1,000,000
1 ml = 1 gram
On solving the above equation, we get -
grams of solute = (23 * 242.0066)/1,000,000
= 0.005566 grams
Mass of Oxygen is equal to 0.005566 grams
