Answer:
Bailee is incorrect. The mass of objects stay the same but the weight will change.
Explanation:
Mass is how much space something takes up, so that wouldn't change on the moon. The weight however would change because the gravitational pull on the earth is different from that on the moon.
I hope this helps!
Bailee explained that when traveling to the moon. The statement of Bailee is incorrect. The mass of the objects stays the same, but the weight will change. The correct option is B.
What is gravity?Gravity is a force that pulls all objects towards itself. It is present on the earth and in the galaxy. Gravity is the cause of all planets, and the sun and the moon stay in their own places.
The weight of items on the moon is equal to their weight on Earth, according to Bailee, thus he needs only bring a small amount of luggage. The mass is the quantity of matter. The mass never changes, only the weight changes of an object when they are on different planets.
Thus, the correct option is B. The mass of the objects stays the same, but the weight will change.

B. 100.53degree C
C. 100.84degree C
D. 101.39degree C
E. 101.94degree C
Answers
Answer:
A
Explanation:
Because it have more glucose
At 100.25 degree C temperature does water boil if 75.0 g of glucose (180.1 g/mol) is added to 400 g of water. Hence option A is correct.
What is temperature?Temperature is defined as the measuring a substance's degree of heat or cold. The direction of heat transfer when two bodies with different temperatures are kept in touch depends on the temperature. An instrument that measures temperature is a thermometer.
Glucose is defined as one of the carbohydrates classified as simple sugars. The brain is the most energy-hungry organ in the body and uses half of the body's sugar energy due to its abundance of nerve cells, or neurons. Thinking, memory, and learning are all tightly correlated with blood glucose levels and how effectively the brain uses this fuel.
Thus, at 100.25 degree C temperature does water boil if 75.0 g of glucose (180.1 g/mol) is added to 400 g of water. Hence option A is correct.

What is the final temperature of water given an initial temperature of 28 ˚C, a mass of 7 g, and heat (q) of 184 J (Specific Heat of water = 4.184 )?
Answers
Answer:34.28 Degree celcius
Explanation:The heat given is equal to the change in temperature multiplied by the mass and the specific heat capacity
This gives the equation:Q=mc∆T
Where Q=184,m=7, specific heat capacity=4.184,∆T=X-28,
But ∆T=Final temperature (T'')-Initial temperature (T')
Therefore the equation becomes
184=7×4.184(X-28)
Solving the remaining linear equation gives you X as 34.28°C
An ion is formed by either
Answers
Explanation:
By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. When an ion is formed, the number of protons does not change.
Answer:
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions.
Explanation:
by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.

Answers
For exothermic processes, spontaneity will only occur if the entropy positive with all temperature or if the entropy is negative with only low temperature.
Since the given equation decomposed from 2 moles of gas into 3 moles of gas, we know that entropy is positive. Thus the reaction will be spontaneous at all temperature.

Balance this equations pH3+O2=P4O10+H2O
Answers
Because there are 4 P on the right side, we have to put a coefficient of 4 on the left to balance out the P.
This would give us 12 H on the left and 2 H on the right, so we have to put a 6 on the right to balance out the H.
Now we have 16 O on the left and 2 on the right, so a coefficient of 8 is required to balance out the O.

Which type of model best represents crystals?
A. ribbon

C. ball-and-stick
D. Lewis dot
Answers
A space filling model is a representation in which atoms of a compound appear as spheres of equal diameter. Crystals are best represented using space filling model.
Crystals are composed of atoms or molecules of a substance that are arranged in a regular and repeating pattern.
While ball and stick models offer an effective representation for discrete molecules, a space filling model is more apt for a crystal since the components are repeating at regular intervals.
Hence the correct answer is option B: space-fill. The space filling model of sodium chloride crystal is shown in the image attached.
