Answer:

Explanation:

I could have set up an experiment to determine the density of the metal in the jar. When I derive the density of the metal, I will compare it with that of every other metal to see if it properly fits any.

Density is the mass per unit volume of substance. It is the amount of substace contained per unit volume.

To find the density of the metal, the mass of the metal is obtained by directly weighing it. The volume is found by immersing the metal in water as it will sink. The volume of the water displaced is the volume of the metal. A measuring cylinder or an overflow is used to determine the volume of the liquid displaced.

     Then:

             Density = \frac{mass}{volume}

In experiment 1, how many moles of benzoic acid are present? how many moles of sodium bicarbonate are contained in 1 ml of a 10%
nexus9112 [7]

First, let us calculate the moles of solute or sodium bicarbonate is in the 1 ml solution.

<span>moles  = 1 mL * (1 g / 9 mL) = 0.11 moles</span>

 

The molar mass of sodium bicarbonate is 84 g/mol, therefore the mass is:

mass = 0.11 moles * 84 g/mol

<span>mass = 9.33 g</span>

A certain chemical reaction releases of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put in
m_a_m_a [10]

To relate the quantity of a substance to the amount of heat transferred and heat capacity, temperature, number of moles is given by

q=ncpΔT

where

n is number of moles

cp is molar heat capacity

ΔT=Tfinal−Tinitial is the temperature difference

What particles would you find in a nucleus of an atom
sammy [17]

Answer:

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.
