The gas generated by four antacid tablets has a greater volume
The gas generated by two antacid tablets has a greater volume
The two reactions produce the same amount of gas
I don't know
Answer: The correct answer is the gas generated by four antacid tablets has a greater volume
Explanation:
In the question, it is given that pressure and temperature of the gas remain constant and we need to compare the volume of the gas produced by 4 antacid tablets and 2 antacid tablets.
As, antacid is the limiting reagent. Hence, more the tablets, more gas will be produced.
Hence, more gas will be produced by four antacid tablets than the gas produced by 2 antacid tablets.
To compare the volume, we use Avogadro's Law which states that volume is directly proportional to the number of the gas at constant pressure and temperature.
(At constant Temperature and Pressure)
Hence, volume will be greater for the gas produced by four antacid tablets.
Therefore, the correct answer is the gas generated by four antacid tablets has a greater volume
b. the chloride ion is twice the size of the magnesium ion.
c. magnesium and chlorine form a double covalent bond.
d. there are two chloride ions for each magnesium ion.
Answer:
The chloride ion accepted two electrons from the magnesium ion.
Explanation:
1. In ionic bonding, only ions of the same element combine to form a compound.
2. In metallic bonding, valence electrons can move freely between atoms.
3. Substances formed through ionic bonding are not considered compounds.
4. In metallic bonding, electrons are transferred between elements in fixed ratios.
Answer: In metallic bonding, valence electrons can move freely between atoms
Explanation:
when metals bond to one another, their outermost energy levels overlap. this allows valence electrons to move freely between atoms in what is sometimes called a “sea of electrons
B) KBr
C) CH3CH2OH
D) HCl
E) C6H6
How is this determined?
The rates of the forward and reverse reactions are unequal.
The concentrations of the products and reactants do not change.
The forward reaction stops at 500 K.
The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.
A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.
