The law of constant proportions affects the ratio when two or more substances combine to form a new substance. The law of constant proportion, also known as Proust's law or the law of definite composition, states that a chemical compound will always have its component elements in a fixed proportion, regardless of the pathway undertaken to prepare that substance.<span />
Answer:
369 ml
Explanation:
Mass of Aluminium (Al) = 20 g
Molar concentration = 2.007M
Molar concentration = Number of moles / Volume
The relationship between mass and number of moles;
Number of moles = Mass / Molar mass
Number of moles = 20 / 27 = 0.741 mol
2.007 = 0.741 / Volume
Volume = 0.741 / 2.007 = 0.369 L
converting to millilitres by multiplying by 1000
Volume = 0.369 * 1000 = 369 ml
R = 1.3 A° = 1.3 × 10^(-10) m
V = 9.20277208×10^(−30) m.
A hurricane is a type of severe cyclone formed when winds rotate as the pressure between low and high-pressure areas increases.
<h3>What is a hurricane?</h3>
A cyclone is a violent storm that occurs when cyclone winds exceeds a speed of 74 miles (119 kilometers) per hour.
Hurricanes are classified according to their strength and catastrophic potential on a scale ranging from 1 to 5 (more violent).
In conclusion, a hurricane is a cyclone formed when a it rotates as the low and high-pressure areas increases.
