Use a graph to solve the equation on the interval

Chemistry
1 answer:
Fofino [41]3 years ago
8 0
In order to solve this graphically, you would construct two lines:
The first of y = √2
The second of y = sec(x)

The solutions will be the intersections over the given domain.
Solving mathematically:
sec x = √2
1/cos(x) = √2
cos (x) = 1/√2

x = -π/4 and π/4

Which element has the following electron configuration: <br> 1s22s22p63s23p64s23d104p65s24d105p5
Natasha2012 [34]
Try adding spaces next time! That's iodine. Check all of the numbers to make sure all of the orbitals are filled, then find the ones which aren't. In this one, only the 5p5 subshell isn't full. 5p5 is the fifth row on the right side, count across the nonmetals and metalloids until the fifth one (a halogen). That's iodine, and that's your answer!

How was Earth’s atmosphere changed during the Great Oxygenation Event?
SpyIntel [72]

Consequences of oxygenation. Eventually, oxygen started to accumulate in the atmosphere, with two major consequences. Oxygen likely oxidized atmospheric methane (a strong greenhouse gas) to carbon dioxide (a weaker one) and water.

Which scientist discovered that the atomic number, rather than the atomic weight, is more responsible for the properties of an e
myrzilka [38]

<em>Answer:</em>

  • The correct option is Moseley who has discovered the atomic number.

<em>Explanation:</em>

  • In 1913, H. Moseley discovered a new properties of an element atomic number. He observed that elements in the periodic table can be arranged better according to atomic number rather than atomic mass.
  • The atomic number of any elements is always equal to numbers of electrons in it.

A 2kg metal cylinder is supplied with 1600J of energy to heat it from 5*C to 13*C. What is the SHC of the metal?
gtnhenbr [62]

Answer:

100Jkg/°C

Explanation:

Given parameters:

Mass of metal  = 2kg

Amount of heat energy  = 1600J

Initial temperature  = 5°C

Final temperature = 13°C

Unknown:

Specific heat capacity of the metal  = ?

Solution:

Specific heat capacity of a body is the amount of heat needed to raise the temperature of unit mass of a body by 1°C.

  H  = m x C x (T₂ - T₁ )

H is the amount of heat

m is the mass

C is the unknown specific heat capacity

T is the temperature

     Insert the parameters and solve;

  1600 = 2 x C x (13 - 5)

   1600  = 16C

        C = 100Jkg/°C
