M(NaCl)/{2M(NaCl)}=m(Cl₂)/M(Cl₂)
m(Cl₂)=M(Cl₂)m(NaCl)/{2M(NaCl)}
m(Cl₂)=70.90*7.5/{2*58.44}=4.55 g
m(Cl₂)=4.55 g
Carbon Dioxide has two polar C=O. bonds, but the geometry of Carbon dioxide is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.
I hope this helps :)
Answer:
Coefficient's are 2, 2, 1
Explanation:
We are given;
Unbalanced equation;
H₂O₂ → H₂O + O₂
We are required to determine the suitable coefficients that would balance the equation.
- We need to know that for an equation to obey the law of conservation of mass it has to be balanced.
- Balancing involves making sure that the number of atoms of each element are equal on both sides of the equation.
In this case;
To balance the equation we put the coefficients 2, 2, 1 respectively
Therefore;
The balanced equation is;
2H₂O₂ → 2H₂O + O₂
Thus, Suitable coefficients are, 2, 2, 1
Balance Chemical equation is,
P₄ + 10 Cl₂ → 4 PCl₅
According to Balance Equation,
123.89 g (1 mole) of P₄ reacts to produce = 4 Moles of PCl₅
Then,
23 g of P₄ will react with excess Cl₂ to produce = X moles of PCl₅
Solving for X,
X = (4 mol × 23 g) ÷ 123.89 g
X = 0.742 g of PCl₅
Result:
When 23 g of P₄ is reacted with excess Cl₂, 0.742 g of PCl₅ is produced.
Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand
