Answer:</h3>
Pb₃O₄ + 4HNO₃ → 2Pb(NO₃)₂ + PbO₂ + 2H₂O
<h3>
Explanation:</h3>
- Balancing a chemical equation involves putting appropriate coefficients on the reactants and products to make the number of atoms of each element involved equal on both sides of the equation.
- When a chemical equation is balanced then it obeys the law of conservation of mass.
- The law of conservation of mass requires the mass of reactants to be equal to the mass of the products.
- In this case, to balance the equation, we put the coefficients 1, 4, 2, 1 and 2 receptively on the equation.
Thus, the balanced equation will be;
Pb₃O₄ + 4HNO₃ → 2Pb(NO₃)₂ + PbO₂ + 2H₂O\
- Therefore, on the reactants side there are 3 Pb atoms, 16 O atoms, 4 H atoms and 4 nitrogen atoms.
- Product side : 3 Pb atoms, 16 O atoms, 4 H atoms and 4 nitrogen atoms.
Thus, the equation obeys the law of conservation of mass.
Then you will multiply the number of moles by 6.022×1023formula units/mol . To determine the molar mass of a compound, add the atomic weight on the periodic table in g/mol times each element's subscript. Since the formula unit CaO has no subscripts, they are understood to be 1
the answer is photosynthesis
The correct answer is 0.9803 atm
Given, pressure of nitrogen = 745 mmHg
Conversion factor: 760 mmHg = 1 atm
Converting 745 mmHg to 1 atm
745 mmHg x ( 1 atm / 760 mmHg) = 0.9803 atm
So is the pressure of nitrogen is 0.9803 atm
That all angles are the same in degress
