Someone thought there was water in Beaker C. He drank some and quickly spat out.He said that it was salty. Explain why this happened.

Answers

Answer 1

Answer:

He assumed wrongly

Explanation:

It happened this way because the person assumed wrongly.

Most other compounds have the same physical appearance as water especially when in liquid form.

This can be a very tricky one in the laboratory. The sense of taste is not the best way to fathom what a particular compound is made up of. This is the reason why this student or person faced this sort of problem. Water has different properties that can be tested for using simple techniques in the laboratory.

Answers

Answer:

See explanation

Explanation:

In the section A,B

C triple bond O has a higher bond energy. A triple bond is shorter and more difficult to break hence they have a higher bond energy.

For the same reason in the C,D section; C triple bond N has a higher bond energy.

In the next section, the higher the bond order the shorter the bond. Hence C triple bond C is the shortest in the A,B section while C triple bond O is the shortest in the C,D section. Both have a bond order of 3.

In the A,B section; I is larger than Br hence H-Br has the shortest bond length.

In the C,D section; Br is larger than Cl hence P-Cl has the shortest bond length.

10. Haley the hummingbird can fly from a pansy flower to a hibiscus flower 20 meters away in 5 seconds.
What is her speed?

Answers

Answer:

4

Explanation:

Speed=Distance/time, so 20/5 divide time divided by distance. so the answer is 4.

The speed of Haley the hummingbird is 4 m/s.

From the question,

We are to calculate the speed of Haley the hummingbird

Speed is given by the formula

[tex]Speed =\frac{Distance\ traveled}{Time\ taken}[/tex]

From the given information,

The hummingbird can fly from a pansy flower to a hibiscus flower 20 meters away in 5 seconds.

That is,

The bird can cover a distance of 20 meters in 5 seconds.

Therefore,

Speed of the hummingbird = [tex]\frac{20}{5}[/tex]

Speed of the hummingbird = 4 m/s

Hence, the speed of Haley the hummingbird is 4 m/s.

ii) then the mixture is filtrated and so the sand and the salt water was seperated

iii) the salt water is heated with the help of burner until the water gets evaporated

iv) after the water gets evaporated, the salt is remained in the container

3. observation:

on adding water to the mixture, the salt is completely dissolved in the waterwhen filtrated the sand is seperated from the salt waternow the salt water when heated with the burner until the evaporation, the water is evaporatedthe salt is precipitated and remained in the container

Sedimentary rocks begin forming when existing rocks are worn away by wind and rain in a process called weathering. Weathering breaks rock into smaller pieces called sediment. Erosion is the removal and movement of sediment. Weathering and erosion happen slowly, over thousands and even millions of years. Eventually, layers of sediment are deposited on top of one another and pressed together. Sedimentary rock is formed when sediment sticks together after liquid is squeezed out. Sometimes, fossils get trapped between sediment layers.The sediment of sedimentary rocks can range in size from a grain of sand to a shell or pebble. The name of the rock thats created depends on the sediment that its made of. For example, shale is made of clay. Conglomerate is made of coarse sediment the size of small pebbles. The sediments of limestone are small shells.Which of the following is an example of erosion?AWind breaking down an existing rock into smaller pieces.BLayers of sediment pressed and sticking together.CSmall shells being moved by water to the shore.DAnimal fossils getting trapped between sediment layers.
