According to the fact that t<span>hey both include the reaction change of elements through different processes, there should be a nice connection between them. In math, numbers pose as an element, and in chem - </span><span>elements are physical things. Both of them can change due to reaction or a formula.</span>
Answer:
3.91 × 10⁴ J/mol
Explanation:
We can calculate the heat of solution using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the solution
m is the mass of the solution
ΔT is the change in the temperature
The mass of LiCl is:
The mass of the solution is:
m = mLiCl + mH₂O = 10.6 g + 200.0 g = 210.6 g
Q = c × m × ΔT = (4.184 J g⁻¹ °C⁻¹) × 210.6 g × 11.08 °C = 9763 J
In a constant pressure calorimeter, the molar enthalpy of solution for LiCl is:
Answer:
Cedar, mahogany, red wood or something else is fine, but the only downside is that it will cost you more. However, a project that is partially or fully exposed to the elements, something more than normal lumber is a must. The most cost effective method is to use pressure treated lumber.
Explanation:
<span>The measurement 4.06 x 10^-5g represents: 0.0000406 g</span>
Answer:
1. They debated about many things.
2. Greek philosophers debated about things. They did not have a scientific/experiment based approach to studying nature. They did not have tools.
3. Democritus
4. Democritus had the basic idea of atoms, even though he had no experimental evidence to support his thinking.
5. taught that there were substances called atoms and that these atoms made up all material things. The atoms were unchangeable, indestructible, and always existed.
