Answer:
By putting a coefficient 4 on NaI and 2 on Na₂SO₄
4NaI + Pb(SO₄)₂ → Pbi4 + 2Na₂SO₄
Explanation:
- A chemical equation is balanced for it to obey the law of conservation of mass.
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products.
- Balancing involves putting coefficients on reactants and products to get an equal number of atoms of each element on either side of the equation.
- In this case, putting a coefficient four on NaI and two on Na₂SO₄ will make the equation to be balanced.
- Therefore, the balanced chemical equation is;
4NaI + Pb(SO₄)₂ → Pbi4 + 2Na₂SO₄
Answer:
Explanation:
Here, we want to get the new volume of the gas
What we need to know is the law that connects volume and pressure at constant temperature
The law that supports this is the Boyle's law
It states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature
Mathematically, we can have this as represented as:
We can proceed mathematically to solve as follows;
Answer is:
Less than the vapor pressure of pure water
Answer is: (4) proton and neutron.
One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).
The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of one nucleon (1.66·10⁻²⁷ kg).
For example, one carbon atom has mass of 12 amu (unified atomic mass).
The electron has a mass that is approximately 1/1836 that of the proton.
