The pressure will continue to build up eventually causing a release of pressure or an explosion.
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)

Answer:
116.88 g
Explanation:
Step 1: Write the balanced equation for the synthesis of NaCl
Na + 1/2 Cl₂ ⇒ NaCl
Step 2: Calculate the moles corresponding to 45.978 g of Na
The molar mass of Na is 22.990 g/mol.
45.978 g × 1 mol/22.990 g = 1.9999 mol
Step 3: Calculate the number of moles of NaCl formed from 1.9999 moles of Na
The molar ratio of Na to NaCl is 1:1. The moles of NaCl formed are 1/1 × 1.9999 mol = 1.9999 mol.
Step 4: Calculate the mass corresponding to 1.9999 moles of NaCl
The molar mass of NaCl is 58.443 g/mol.
1.9999 mol × 58.443 g/mol = 116.88 g
Answer:
C. Solid in liquid
Explanation:
Seawater is an example of a solid in liquid solution.
Sea water is made up of:
- water
- mineral salts
- dissolved gases
A liquid solution is always made up of a solute being dispersed within the solvent medium.
The solvent is the liquid or fluid medium.
Such solutions are homogeneous because the solute particles are distributed evenly or uniformly in the solvent.
The solute is usually present in smaller amount compared to the solvent.
Hey there! Here is the answer:
B.) decrease; increase
Here's why:
As you move from left to right across a period on the periodic table the size of an atom will decrease. As you move from top to bottom down a group on the periodic table the size of an atom will increase.
I really hope this answer helps you out! :)
