What would he have concluded about the relative masses of nitrogen and hydrogen atoms
One nitrogen atom and one hydrogen atom, each weighing six mass units, make up an atom of ammonia.
According to his book "A New System of Chemical Philosophy," published in 1808, a compound of ammonia has a nitrogen to hydrogen mass ratio of 1 to 5.Dalton proposed that the concept of atoms could be used to explain the laws of conservation of mass and definite proportions. He proposed that atoms, which he described as "solid, massy, hard, impenetrable, moving particle(s)," are the smallest, indivisible units of matter.Learn more about Dalton's atomic theory here:

How many total atoms are in 0.310 g of P2O5?
The number of atoms in 0.310 g of P₂O₅ is 6.57 × 10²⁰ atoms.
How to calculate number of atoms?The number of atoms in a substance can be calculated by multiplying the number of moles present in that substance by Avogadro's number as follows:
no of atoms = no of moles × 6.02 × 10²³
According to this question, there are 0.310grams of phosphorus oxide (P₂O₅). The molar mass of P₂O₅ is 283.889 g/mol.
no of moles = 0.310g ÷ 283.889 g/mol
no of moles = 0.00109moles
The number of atoms = 6.02 × 10²³ × 0.00109 moles = 6.57 × 10²⁰ atoms
Therefore, 6.57 × 10²⁰ atoms is the number of atoms in P₂O₅.

B. The MOST plausible prediction and explanation of the ending mass is 3g of (AgCl + NaBr); matter is conserved so the total mass will be the same in the beginning and end.
What is the law of conservation of matter?
The law of conservation of matter states that mass cannot be created nor destroyed, but can be converted from one form to another.
When the law of conservation of matter or mass is applied in a chemical reaction we will observe the following;
the mass of the reactants and mass of products are conservedthe total mass of the reactants is equal to the total mass of the producteach component of the reaction is conservedno new element is createdFrom the given chemical reaction;
2 g of NaCl + 1 g of AgBr = ?AgCl + ? NaBr
Based on the law of conservation of matter, the total mass of the reactants (3 g) must be equal to the total mass of the product (3 g) because matter is conserved.
Thus, the MOST plausible prediction and explanation of the ending mass is 3g of (AgCl + NaBr); matter is conserved so the total mass will be the same in the beginning and end.

Calcium nitrite is used as a corrosion inhibitor in lubricants. What is the molality of a solution prepared by dissolving 18. 5 g of calcium nitrite in 83. 5 g of distilled water?.
The molality of a solution prepared by dissolving 18.5 g of calcium nitrite in 83.5 g of distilled water is 1.677m.
Molality is defined as the ratio between the amount of solute in a solution and the mass of corresponding solvent in the solution.
m = moles of solute/mass of solvent(kg)
If we have 18.5 g of calcium nitrite, using the formula for molar mass, solve for its number of moles.
n = mass/MM
moles of solute = 18.5 g calcium nitrite / 132.089 g/mol
moles of solute = 0.1400570827 moles calcium nitrite
Using the formula for molality, solve the molality of solution prepared by dissolving 0.1400570827 moles calcium nitrite in 83.5 g of distilled water.
m = moles of solute/mass of solvent(kg)
m = 0.1400570827 moles calcium nitrite / 83.5 g(1kg/1000g)
m = 0.1400570827 moles calcium nitrite / 0.0835 kg

If 43.6J of heat is added to a 0.985g block of metal, the temperature of the metal increases by 12.4C. Calculate the specific heat capacity of the metal.
The specific heat capacity of the metal when the temperature rises by 12.4°C is 3.569 J/g°C.
What is specific heat capacity?Specific heat capacity is defined as the heat capacity of the substance divided by the mass of the substance.It is the amount of heat added to one unit mass of substance to increase it's temperature by one unit.The SI unit is joule per kelvin per kilogram.
It varies with temperature and for each different state of matter it is different.Specific heat capacity of a substance is higher when it is allowed to expand as a result of heating.It is measured by a technique called differential scanning calorimetry.
It is calculated by the given formula,
W=mcΔt
where W=energy supplied
m= mass of substance
c=specific heat capacity
Δt= temperature change
Substituting the values given in the problem in the above equation,
c=43.6/0.985×12.4=3.569 J/g°C
Thus, the specific heat capacity of metal is 3.569 J/g°C.

2. Conduction occurs best in metals because they have a high
The correct answer is when electrons bump into atoms and other electrons.
Because of how tightly packed their particles are, metals are particularly good heat conductors because vibrations are transferred very fast. Additionally, they have a lot of free electrons.
Metals get their strength and other qualities from these when they gently float through the framework. The free electrons that are nearest to the heat source are heated as the metal warms up. As a result, they move more quickly through the metal, crashing into other electrons as well as atoms. They naturally vibrate more quickly as a result (or move through the metal faster in the case of collisions with other free electrons). As a result, the metal swiftly dissipates the heat.
