B is mixing C is mass becoming a liquid and D. is dissolving no chemical reaction happened there.
Hope that helps!
Weather is the temperature or climate over a short period of time.
Answer:
The mass of CO22 in total is 264 g.
The atomic mass for C is 12 g / mole.
The molar mass for CO22 is (12 + (2 × 16)) = 44 g / mole.
m C = (12 / 44) × 264 = 72 g
So, there are 72 g of C in 264 g of CO2

3.6 x 10²³
Explanation:
Given parameters:
Number of cell per body = 60 trillion body cells
Population of the earth = 6 billion
Unknown:
Total number of living human body cells = ?
Solution:
To solve this problem, simply find the product:
Total number of living human body cells = number of cell per body x population of the earth
1 trillion = 1 x 10¹²
60 trillion = 6 x 10¹³
1 billion = 1 x 10⁹
6 billion = 6 x 10⁹
Total number of living human body cells = 6 x 10¹³ x 6 x 10⁹
= 6 x 6 x 10⁽¹³⁺⁹⁾
= 36 x 10²² or 3.6 x 10²³
