If the total mass of the product, mercuric oxide, HgO, is 433.2 grams, what is the total mass of the Mercury and Oxygen on the reactants side of the equation?
What are the grams?
To determine the total mass of mercury (Hg) and oxygen (O) on the reactants side of the equation, we need to know the balanced chemical equation for the reaction involving mercuric oxide (HgO).
Without the specific reaction, we cannot accurately determine the mass of the mercury and oxygen on the reactants side. If you provide the balanced chemical equation, I can assist you in calculating the mass.
2Hg + O2---> 2HgO
If the total mass of the product, mercuric oxide, HgO, is 433.2 grams, what is the total mass of the Mercury and Oxygen on the reactants side of the equation?
What are the grams?
In the balanced chemical equation:
2Hg + O2 ---> 2HgO
we can see that there are 2 mercury atoms (Hg) and 1 oxygen molecule (O2) on the reactants side. To calculate the total mass of mercury and oxygen on the reactants side, we need to know the molar mass of each element.
The molar mass of mercury (Hg) is approximately 200.59 grams/mol, and the molar mass of oxygen (O) is approximately 16.00 grams/mol.
Since we have 2 mercury atoms, the total mass of mercury on the reactants side is:
2 mol Hg * 200.59 g/mol Hg = 401.18 grams of mercury
For oxygen, we have 1 oxygen molecule (O2), so the total mass of oxygen on the reactants side is:
1 mol O2 * 16.00 g/mol O2 = 16.00 grams of oxygen
Therefore, the total mass of mercury (Hg) and oxygen (O) on the reactants side of the equation is 401.18 grams of mercury and 16.00 grams of oxygen.
The correct answers to fill in the blanks are:
The ____ coefficient ______ Response area is the number in ___ front of the element or compound.
A. front
B. coefficient
C. equation
D. right
The correct answers to fill in the blanks are:
The coefficient Response area is the number in front of the element or compound.
In order to determine the coefficient, you would need to look at a chemical equation. A chemical equation is a representation of a chemical reaction where the reactants (starting materials) are placed on the left side of an arrow and the products (resulting substances) are placed on the right side. The coefficient is a whole number that is written before a compound or element and indicates the number of moles or molecules of that substance involved in the reaction.
For example, consider the equation: 2H2 + O2 → 2H2O
In this equation, the coefficient for H2 is 2, which means there are 2 molecules of hydrogen gas involved. Similarly, the coefficient for O2 is 1, indicating that there is 1 molecule of oxygen gas involved. The coefficient for H2O is also 2, indicating that there are 2 molecules of water produced.
Therefore, when referring to the number in front of an element or compound in a chemical equation, we use the term "coefficient".
