wich if the following statements best describes why the mass of a bowling ball would not change if it were transported from earth to the moon?


gravity is constant forge

the bowling ball will adapt to the changes in gravity

matter is resistant and changes gravity

the amount of mattet in the bowling ball remains the same

Answers

Answer:

the amount of matter in the bowling ball remains the same

Explanation:

The reason why the mass of the bowling ball on earth and moon remains the same is that matter in the bowling ball remains the same.

Mass of any substance is the amount of matter it contains.

Since there is no loss in matter, the mass of the bowling ball anywhere in the universe will be the same. Only the weight changes due to differences in gravity.

What is the frequency of a photon with an energy of 3.38 x 10-19 J?​

Answers

Hey There!_____________________________________Answer:

[tex]\huge\boxed{5.1x[tex]10^{14}[/tex]Hz}[/tex]

_____________________________________DATA:

E = [tex]3.38 x 10^{-19}[/tex]

h = [tex]6.625x10^{-34}[/tex]

f = ?

_____________________________________SOLUTION:

Energy of Photon is given by,

                                   

                                   E = hf

Rearrange the equation,

                             

                                    f = [tex]\frac{E}{h}[/tex]

where,

           E = energy

           h = planck's constant

           f = frequency

------------------------------------------------------------------------------------------------------------

Substitute the variable in the equation,

 

                                 f = [tex]\frac{3.38x10^{-19}}{6.62x10^{-34}}[/tex]

Simplify the equation,

                               

                                  f = 5.10 x 10^14 Hz

Why is NCl3 not soluble in water?

Answers

Answer:

Explanation:

NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.

Answer:

A polar solute dissolves into a polar solvent and a non-polar compound dissolves into a non-polar solvent, this rule is known as "like dissolves like".

Given the following equation,
HCl aq) + NaOH aq
NaClaq) + H2O(l)
How many moles of H20 will be produced if there are 5 moles of HCI?​

Answers

Answer:

5 moles

Explanation:

Given data:

Number of moles of HCl = 5 mol

Number of moles of H₂O produced = ?

Solution:

Chemical equation:

HCl + NaOH     →   NaCl + H₂O

Now we will compare the moles of HCl with H₂O.

                          HCl            :           H₂O

                             1               :             1

                             5               :            5

5 moles of water will be produced.

calculate the ph of a solution whose(oh^-) is 4.583*10^-5 mole dm cube (pkw=14)​

Answers

pH of solution = 9.661

Further explanation

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

pOH=-log[OH⁻]

[tex]\tt pOH=-log[4.583\times 10^{-5}]\\\\pOH=5-log~4.583=4.339[/tex]

pH+pOH=pKw

[tex]\tt pH=14-4.339\\\\pH=9.661[/tex]

A clam farmer has been keeping records of the water temperature and the number of clams developing from fertilized eggs. The data is recorded above.


What is the dependent variable?

What is the independent variable?

What is the optimum temperature for clam development?

Answers

Answer:

The dependent variable is the number of clams developing from fertilized eggs.

The independent variable is the water temperature

The optimum temperature for clam development is 30 degrees centigrade.

Explanation:

The graph of the number of clams developing from fertilized eggs and water temperature is attached to this answer.

The independent variable is being manipulated in an experiment. As it changes, it produces a corresponding change in the dependent variable.

Here, the water temperature is the independent variable. As it changes, the number of clams developing from fertilized eggs (dependent variable) also changes alongside.

The optimum temperature is the temperature at which the greatest number of clams developing from fertilized eggs is produced. We can see from the graph that this temperature is 30 degrees centigrade.

Experiments with gold foil indicated that atoms
A)
usually have a uniform distribution of positive charges
B)
usually have a uniform distribution of negative charges
C)
contain a positively charged, dense center
D)
contain a negatively charged, dense center

Answers

Answer:

c

Explanation:

I just learned all this in chemistry too lol

got 100 on the test last week so its good

Experiments with gold foil indicated that atoms contain a positively charged, dense center and the correct option is option C.

Experiments with gold foil, known as the Rutherford gold foil experiment, were conducted by Ernest Rutherford in 1911. In this experiment, he bombarded a thin gold foil with alpha particles.

Most of the alpha particles passed through the foil with little deflection, but some of them were deflected at large angles, and a small fraction even bounced back. This observation led Rutherford to conclude that the atom contains a positively charged, dense center called the nucleus, where most of its mass is concentrated. He proposed the nuclear model of the atom, which became a significant advancement in the understanding of atomic structure.

Thus, the ideal selection is option C.
