Answer:
[tex]\boxed {\boxed {\sf 600 \ kg/m^3}}[/tex]
Explanation:
We are asked to find the density of a bowling ball. The density of an object is its mass per unit volume. It is calculated by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the bowling ball is 3.0 kilograms and the volume is 0.0050 cubic meters.
m= 3.0 kg v= 0.0050 m³Substitute the values into the formula.
[tex]\rho= \frac{3.0 \ kg}{0.0050 \ m^3}[/tex]
Divide.
[tex]\rho= 600 \ kg/m^3[/tex]
The density of the bowling ball is 600 kilograms per cubic meter.

Does this reaction meet the Law of Conservation of Mass? 2H2 + O2 → 2H2O explain.
Answer:
yes because on the left side 4 hydrogen in right side 4 hydrogen on the left side 2 oxygen in the right side 2 oxygen
Answer:
The Law of Conservation of Mass states that the mass of the system must remain constant over time as the system's mass cannot change because energy is not created nor destroyed. To tell if a chemical equation meets this law, check to see if the number of atoms is the same on both sides of the chemical equation.
Reactant Side:
4 atoms of Hydrogen2 atoms of OxygenProduct Side:
4 atom of Hydrogen2 atoms of oxygen.Remember, when counting the atoms in a equation the subscript is the number that represents the quantity of that specific atom. Subscripts are numbers that come after a symbol and below. If an element does not have a subscript, then it is understood that the subscript is 1. The coefficent represents the quantity of molecules, the coefficient multiplies everything in the formula.

Antoine Lavoisier was able to show that mass wasn't lost or destroyed during chemical reactions by weighing all of the matter in the system before and after reactions occurred. What questions would you ask Lavoisier about how he conducted his investigations?
Answer: we can ask simple qs like was it a fair experiment and what he was actually looking for. Other qs include his variables use and that how he has maintained the experiment. Finally we could ask him for his outcome and what it would ahve changed in the near future
Explanation:
A compound is 2. 00% H by mass, 32. 7% S by mass, and 65. 3% O by mass. What is its empirical formula? The first step is to calculate the mass of each element in a 100-g sample of the compound. We use 100 g because it makes the calculations more straightforward. What is the mass of each element in a 100. 0-g sample of the compound? mass H = g mass S = g mass O = g.
Answer:
We assume that there is 100g of the compound (because it makes it easier to calculate) and we turn the percentages into grams.
2% of Hydrogen = 2g of H
32.7% of Sulfur = 32.7g of S
65.3% of Oxygen = 65.3g of O
Now we change the mass of these elements to moles by dividing the mass by the molar mass (which is the value of atomic mass on your periodic table)
2g/1.01g = 1.98 mol
32.7g/32.06g = 1.02 mol
65.3g/16g =4.08 mol
divide all these mol values by the smallest mol value, which is 1.02. (Round the values to whole numbers)
1.98/1.02 = 2 (rounded) of Hydrogen
1.02/1.02 = 1 of Sulfur
4.08/1.02 = 4 of Oxygen
H2SO4 (also known as sulphuric acid) is your empirical formula.

What is a chemical bond?
A. An intramolecular force holding 2 atoms together
B. An attractive force between 2 molecules
C. A gravitational force holding electrons in their orbits
D. An electrostatic force between a proton and an electron
A chemical bond is an electrostatic force between a proton and an electron. Hence, option D is correct.
What is a bond?A chemical bond is what holds atoms together in molecules.
A chemical bond is what holds atoms together in molecules.
Bonds arise from the electrostatic forces between positively charged atomic nuclei and negatively charged electrons (the positions of which in space are determined by quantum mechanics).
Hence, option D is correct.

How many atoms of each element are in the compound AgNO3? (Hint: Ag is the
symbol for silver, N is the symbol for nitrogen, and O is the symbol for oxygen.)
1 silver, 1 nitrogen and 3 oxygen
Subscripts show the number of atoms of each element in a compound
There is no subscript after Ag which shows there is only one silver atom. There is no subscript after N which shows there is only one nitrogen atom. However, there is a 3 in the subscript after O which shows there are 3 oxygen atoms

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons

if the column of water in the water barometer rose to a height of 39 feet, what would the atmospheric pressure be in mm hg?
The atmospheric pressure for a column of water barometer that rose to 39 feet is 874 mmHg
From the given information, to determine the atmospheric pressure at which the column of the water barometer rose, we will need to convert the height of the water column to mmHg.
From the dimensional analysis of standard rate conversion, we know that:
1 feet = 12 inches
1 inch = 25.4 mm
1 mmHg = 13.6 mm of water.
∴
[tex]\mathbf{\implies 39 \ feet \ of \ H_2O \times \dfrac{12 \ in ch \ H_2O}{1 \ feet \ H_2O} \times \dfrac{25.4 \ mm \ H_2O}{1 \ inch \ H_2O} \times \dfrac{1 mmHg}{13.6 \ mm \ H_2O}}[/tex]
= 874.058 mmHg

Students in class argue about whether salt (NaCl) or water (H2O) has stronger intramolecular forces. Which argument is BEST?
Question 3 options:
Water because it is a common material and will have stronger intramolecular force.
Water is attracted to salt and salt dissociates, so water has stronger intramolecular forces.
Salt never melted and water has a lower boiling point, so salt has stronger intramolecular forces.
Salt is a solid and water is a liquid, so water has stronger intramolecular forces.
Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.
Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.
NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.
Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.
