Answer and Explanation:
To calculate this, simply use an equality of proportions:
50 particles : 1 billion particles = <em>x</em> tons : 1.49 million tons
The value of <em>x</em> can be solved for by multiplying the ratio on the left by the value 1.49 million / 1 billion:
So, <em>x</em> = (50)(0.00149) tons = 0.0745 tons
Then, do the same thing for the larger concentration:
<em>x</em> = (200)(0.00149) tons = 0.298 tons
Answer:
A) Concentration
Explanation:
When you add a chemical to itself it becomes more concentrated making it more powerful and faster
Answer:
1. When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules
2. Pure sodium explodes on contact with water
Explanation:
The particals in a physical change alwayd stay the same, but for a chemical change that is the only time they will change. Not during a physical change
<h3>
Answer:</h3>
895.11 g Titanium
<h3>
Explanation:</h3>
Moles of Titanium = 18.7 moles
To get the mass of Titanium;
We use the formula;
Mass = moles × Molar mass
Molar mass = 47.867 g/mol
Therefore;
Mass of Titanium = 18.7 Moles × 47.867 g/mol
= 895.1129 g
= 895.11 g
