The momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball
Momentum is defined as the product of mass and velocity i.e
Momentum = mass × velocity
If we keep the velocity of the object constant, the momentum will depend on the mass of the object.
Thus, the higher the mass, the greater the momentum and the lesser the mass, the smaller the momentum.
From the question given above,
Mass of tennis = 0.5 Kg
Mass of basketball = 2 Kg
Mass of bowling ball = 5 kg
We can see that the bowling ball has a higher mass.
Therefore, the momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball

Explanation:
explain why the pressure in a sealed container of gas decreases when heat is added to the system?
when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!
IT DOES NOT DECREASE

The unbalanced equation below shows the reaction between sodium and water. In the reaction,
hydrogen gas is given off and sodium hydroxide is formed. The gas is collected and there is found to be
1.8 grams of hydrogen. What mass of sodium would have been used in this reaction?
Na + H2O + NaOH + H2
Answer:
41.4 g
Explanation:
2Na(s) + 2H2O (l) ----> 2NaOH ( aq) + H2 (g)
According to the above balnced chemical equation the ratio between moles of H2 gas formed to moles of Na used up is 1:2
Molar mass ( Mass of 1 mol) Of H2 gas is 2 gmol-1
So in 1.8 g of H2 0.9 mol should be present
Therefore no. of moles of Na used should be 2× 0.9 = 1.8 moles
Molar mass of Na= 23 gmol-1
So mass of 1.8 mol of Na = 1.8× 23 g = 41.4g
What structural characteristic do all of the atoms within a group (vertical columns) have in common?
Answer:
The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.
hope this helps
Explanation:
Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
what aspects are not accounted for in the ideal gas law?
The aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.
In the ideal gas law, it it assumed that the molecules of the gas are so far away from each other and thus they do not exert a significant force of attraction on each other. Also, the volume of each molecule of gas is neglected and assumed negligible and thus does not account for the overall volume of the gas.
So, the aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.

Describe the 3 dimensional NaCl lattice.
NaCl has a cubic unit cell, best thought of as a face-central cubic array of anions with an interpenetrating FCC action lattice or (vice versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6 co-ordinates and has a local octahedral geometry.
NaCl lattice exhibit cubic unit cell. The face-centered cubic array of anions with an interpenetrating fcc cation lattice are seen in 3D structure. Each ion is 6-coordinate and has a local octahedral geometry.
What is sodium chloride?Sodium chloride is an ionic compound, formed from the sodium metal and chlorine atom. The ionic bond is formed by loss of one electron from sodium metal to the chlorine atom.
The lattice structure of all metals contains a pool of cations in the sea of mobile electrons. The electrons can be delocalized into the interstices and thus metals conduct electrically and thermally.
In the fcc lattice of NaCl, sodium atoms are arranged at the corners and Cl atoms are at the center of each cube face of the cell. They are assumed to touch along face diagonals.
Atoms are arranged at the corners of the cube with another atom at the cube center also hence there will 4 atoms one unit cell.

which characteristic do valence electrons indicate about reactions between atoms?
Bond number
The characteristic of reactions that depends on valence electrons is the bond type.
In chemistry, a chemical bond could be;
Ionic
Covalent
The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.
When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

What is the correct orientation of the bar magnet, based on the magnetic field
lines shown?
A. South pole on the top edge and north pole on the bottom edge.
B. North pole on the top edge and south pole on the bottom edge
C. South pole on the left end and north pole on the right end
D. North pole on the left end and south pole on the right end
Answer:
b
Explanation:
north is up south is bottom
Answer:
C. South pole on the left end and north pole on the right end
Explanation:
From the figure, we can conclude that the poles of the magnet are on either sides of the magnet
Therefore, options 1 and 2 are excluded
It is a convention that the magnetic field lines move out of the north pole of a magnet and into the south pole of the magnet
From the figure, we can see that the magnetic field lines are moving out from the right end and into the left end
This means that the north pole is at the right end and that the south pole is at the left one
