Quartz is the type of mineral used for both mechanical and chemical weathering
Answer:
10.3 mol Ga(ClO₃)₃
Explanation:
Let's consider the following balanced thermochemical equation.
2 Ga(ClO₃)₃(s) ⇒ 2 GaCl₃(s) + 9 O₂(s) ΔH = - 130.4 kJ
According to the balanced thermochemical equation, 130.4 kJ of heat are released when 2 moles of gallium chlorate react. The number of moles of gallium chlorate that must react to produce 674 kJ of energy is:
674 kJ × 2 mol Ga(ClO₃)₃/130.4 kJ = 10.3 mol Ga(ClO₃)₃
Answer:
Explanation:
To be accurate, it must be able to make measurements that are close to the actual value.
Answer: The moles of HCl are 0.0244
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute = ?
= volume of solution in ml
Now put all the given values in the formula of molality, we get
Therefore, the moles of HCl are 0.0244
Answer:
How do the water molecules closest to the burner compare to the water molecules closest to the surface of the liquid? ... They are closer together and moving slower than those at the surface. They are more spread out and moving faster than those at the surface. The diagram shows the sun's interior.
