Answer:

It is because of Various things that we do, If we did not exist, several animals that went extinct because of us, would have thrived, If it wasn't for us filling the sky with so much CO2's, we wouldn't have the Earth heating up even more. Also, other things that we do such as Urbanization, Desertification, and Deforestation. All of these words will be defined under this text.

Explanation:

Deforestation: When humans cut down too many trees can result in habitat loss/ more CO2's

Desertification: When land used to be a grassland but humans used too much of a resource and turned it into a hot, sandy wasteland.

Urbanization: When you take land and fill it with tons of buildings, homes, and businesses. This can result in over-crowding, and spreading of diseases.

Provide the electronic structure diagram of propene showing all molecular orbitals

exis [7]

Answer:

Explanation:The pi-molecular orbitals in propene (CH3-CH=CH2) are essentially the ... This central carbon thus provides two p-orbitals – one for each pi bond – and these two different p-orbitals have to be perpendicular, leading to a twisted structure as shown: ... It all comes down to where the location of the electron-deficient carbon

A 25.0-mL sample containing Cu2+ gave an instrument signal of 25.2 units (corrected for a blank). When exactly 0.500 mL of 0.027

irga5000 [103]

Answer:

The molar concentration of Cu²⁺ in the initial solution is 6.964x10⁻⁴ M.

Explanation:

The first step to solving this problem is calculating the number of moles of Cu(NO₃)₂ added to the solution:

$C = \frac{n}{V} \\0.0275 = \frac{n}{0.0005} \\$

n = 1.375x10⁻⁵ mol

The second step is relating the number of moles to the signal. We know the the n calculated before is equivalent to a signal increase of 19.9 units (45.1-25.2):

1.375x10⁻⁵ mol _________ 19.9 units

x _________ 25.2 units

x = 1.741x10⁻⁵mol

Finally, we can calculate the Cu²⁺ concentration :

C = 1.741x10⁻⁵mol / 0.025 L

C = 6.964x10⁻⁴ M

Why water is able to stick to the side of a glass

Snezhnost [94]

Answer:

Water uses adhesive forces that allow it to stick to certain surfaces such as glass.

Explanation:

When the angle between vertical direction and the glass wall is small, surface tension is stronger and the component of gravity perpendicular to the glass wall is small. The result of this causes water to stick to the side of a glass.

Hope this helps!
