The force of gravity

Asuming all orbitals are in the same energy level which type of orbital has the lowest energy?

Virty [35]

Answer: C. S orbital

Explanation: The s orbital is the lowest orbital shell which is much closer to the nucleus. This orbital can hold a maximum of 2 electrons, a perfect example for this is the 1s orbital which is the closest to the atomic nucleus.

How many moles of TNT would be detonated if you used 539.88 grams of TNT? The structure of TNT is C7H5N3O6. Round your answer to

Kruka [31]

Answer:

Moles of TNT = 2.38 moles

Explanation:

First , calculate the molar mass of the compound TNT

The formula is : C7H5N3O6

How to calculate molar mass?

Molar mass : It is the mass of substance in grams which is present in 1 mole of the compound.It is calculated by:

Molar mass = Number of atoms x the atomic mass of the element

Atomic mass of the elements are given below :

C = 12.0107

H = 1.0079

N = 14.0067

O = 15.9994

Molar mass of C7H5N3O6 =

= (7 x C) + (5 x H) + (3 x N) + (6 x O)

= 7(12.0107) +5(1.0079) + 3(14.0067) + 6(15.9994)

Molar mass = 227 .13 gram/mole

Mole are calculated using the formula:

$Moles =\frac{given\ mass}{Molar\ mass}$

Given mass = 539.88 grams

Molar mass = 227.13 g/mole

$Moles =\frac{539.88}{227.13}$

= 2.3769

Moles = 2.38 moles

Ivahew [28]

The answer is: <span>Light strikes a beautiful white perch under water. This light is reflected back to your eyes allowing you to see the fish. As the light left the water it changes speed causing the light to bend away from the normal.
Hope this helps!

Homogeneous mixture that does not settle out upon standing reflect light is an element. solid. hydrated.

andrey2020 [161]

Homogeneous mixture that does not settle out upon standing but which will reflect light is called COLLOIDS.
There are three types of homogeneous mixtures, these are: solutions, colloids and suspension. Colloids are usually distinguished by Tyndall effects. Light passing through a colloidal dispersion will be reflected.<span />
