Methane and ethane are both made up of carbon and hydrogen. In methane, there are 12.0 g of carbon for every 4.00 g of hydrogen,

Sati [7]

Answer:

The answer is: Law of multiple proportions

Explanation:

The law of multiple proportions is a law of chemical combination given by Dalton in 1803.

According to this law, if more than one chemical compound is formed by combining two elements, then the mass of an element that combines with the fixed mass of other element is represented in the form of small whole number ratio.

<u>Therefore, is an illustration of the law of the law of multiple proportions.</u>

Method used to separate ethanol from propanol

N76 [4]

Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.

Scientists tracking a flock of ducks found that, on average, the ducks flew 740 km south in 12 hours. What were the speed and ve

Verizon [17]

1) 17.1 m/s

2) 17.1 m/s south

Explanation:

The speed of an object is a scalar quantity indicating "how fast" is the object moving, regardless of its direction of motion.

Being a scalar quantity, it has only a magnitude, while it doesn't have a direction.

The speed of an object is given by the formula:

$v=\frac{d}{t}$

where:

d is the distance covered by the object, which is the total length of the path covered by the object

t is the time taken to cover the distance d

In this problem we have:

$d=740 km =740,000 m$ is the distance covered by the ducks

$t=12 h \cdot 60 \cdot 60 =43,200 s$ is the time taken

Substituting, we find:

$v=\frac{740,000}{43,200}=17.1 m/s$

The velocity of an object is a vector quantity indicating how fast the object is moving in a certain direction.

Being a vector, velocity has both a magnitude and a direction.

The magnitude of the velocity is given by:

$v=\frac{d}{t}$

where

d is the displacement, which is the shortest distance in a straight line between the initial position and the final position of motion

t is the time taken for the displacement d to occur

And the direction is equal to the direction of the displacement.

In this problem:

$d=740 km = 740,000 m$ south is the displacement

$t=12 h \cdot 60 \cdot 60 =43,200 s$ is the time taken

Substituting, we find:

$v=\frac{740,000}{43,200}=17.1 m/s$ south
