Answer:
the number of protons and neutrons at both terminals are equal
Explanation:
When the number of positive charge and negative charge are both equally the terminal, it becomes neutral and out of charge, because first it undergo enough chemical reaction and there is no remaining tendency for positive and negative charges to get separated. When this tendency dies, the battery also will run out of charge.
<u>Answer:</u> The mass of 1 mole of lithium is 6.941 grams.
<u>Explanation:</u>
To calculate the mass of a compound or element, we use the formula used to calculate the number of moles:
Where,
Number of moles of lithium = 1 mole
Given mass of lithium = ? g
Molar mass of lithium = 6.941 g/mol
Putting value in above equation, we get:
Hence, the mass of 1 mole of lithium is 6.941 grams.
Explanation:
In general, to balance an equation, here are the things we need to do:
Count the atoms of each element in the reactants and the products.
Use coefficients; place them in front of the compounds as needed.
Answer:
Answers are in the explanation
Explanation:
A bomb calorimeter is a <em>constant volume </em>calorimeter in which medition of change in temperature allows the medition of change in internal energy (ΔU) for chemical reactions or physical changes.
This ΔU can be converted in ΔH thus:
ΔH = ΔU + PV
That means that:
A bomb calorimeter is a piece of equipment designed to measure <em>delta H</em>
As there was said:
Reactions carried out in a bomb calorimeter occur at constant <em>volume</em>
To calculate the heat absorbed or released by a reaction carried out in a bomb calorimeter, we use the equation: <em>q = C * delta T</em>
Where C is the heat capacity of the calorimeter, delta T is the change in temperature and q is the heat produced in the chemical or physical process

Based on the nature of chemical equilibrium, the system reached equilibrium first at the time T2.
<h3>What is chemical equilibrium?</h3>
Chemical equilibrium refers to the state of a reversible chemical reaction in which the rate of forward reaction for the the formation is equal to the rate of backward reaction for the formation of reactants.
In the table of the decomposition reaction given above, the system reached equilibrium first at the time T2 when the concentration of the reactant and products were the same.
