Hi !
1.the theological perspective of man's dominance in a dominant world was shown to be no longer tenable.
2. Heliocentricity uprooted the theological doctrine that the universe revolved around Man as the paramount and most glorious end-result of Creation, with the Sun, the Stars, the other Planets and the whole Universe .
Hood it helps and have a wonderful day!
Because PE is proportional to the height of where the mass is, and the top of the swing is the highest the mass of the 'bob' ever gets.
Explanation:
The pH of a solution can you be found by using the formula
![pH = - log [ { H_3O}^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7B%20H_3O%7D%5E%7B%2B%7D%5D)
Since we are finding the [H3O+] , substitute the value of the pH and find it's antilog
We have
![4.63 = - log[ { H_3O}^{+}] \\ [ { H_3O}^{+}] = {10}^{ - 4.63} \\ \\ = 2.344 \times {10}^{ - 5} mol {dm}^{ - 3}](https://tex.z-dn.net/?f=4.63%20%3D%20%20-%20%20log%5B%20%7B%20H_3O%7D%5E%7B%2B%7D%5D%20%5C%5C%20%5B%20%7B%20H_3O%7D%5E%7B%2B%7D%5D%20%20%20%3D%20%20%7B10%7D%5E%7B%20-%204.63%7D%20%20%5C%5C%20%20%20%5C%5C%20%20%3D%202.344%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%205%7D%20mol%20%7Bdm%7D%5E%7B%20-%203%7D%20%20)
Hope this helps you
Answer:
The answer to your question is 42.9 g of Ca
Explanation:
Data
mass of Ca = ?
mass of N₂ = 10 g
Balanced chemical reaction
3Ca + N₂ ⇒ Ca₃N₂
Process
1.- Calculate the molar mass of the reactants.
Ca = 3(40) = 120 g
N₂ = 2(14) = 28 g
2.- Calculate the mass of Calcium using proportions and the molar mass of the reactants.
120 g of Ca ---------------- 28 g of N₂
x ---------------- 10 g of N₂
x = (10 x 120) / 28
x = 1200 / 28
x = 42.9 g of Ca
Answer:
If the planet has a lower orbital radius it means the planets proximity to the sun is farther away. The climate of the planet will be colder than a planet that would have a closer proximity to the sun.
