Answer:

Photodisintegration!

Explanation:

also called Phototransmutation, in physics, nuclear reaction in which the absorption of high-energy electromagnetic radiation (a gamma-ray photon) causes the absorbing nucleus to change to another species by ejecting a subatomic particle, such as a proton, neutron, or alpha particle.

The <span>simple machine found on the head of the ax is </span>Wedge. A wedge is an inclined plane that can be moved. When an ax is used to split wood, the ax handle exerts a force on the blade of the axe, which is the wedge. That force pushes the wedge down into the wood. The wedge in turn exerts an output force splitting the wood in two.

Assoli18 [71]

Answer:

The entropy change of carbon dioxide = 0.719 kJ/k

Explanation:

Given:

1.5 m - 3 insulated rigid tank contains 2.7 kg of carbon dioxide at 100 kPa

The objective is to determine the entropy change of carbon dioxide

Formula used:

ΔS=

Solution:

On considering,

$C_{P} =0.846 kJ/kg K\\C_V=0.657 kJ/kg k\\$

ΔS= $mc_{v} lu\frac{p_{2} }{P_{1} }$

On substituting the values,

ΔS= $2.7*0.657lu\frac{150}{100}$

ΔS=0.719 kJ/k

Which event occurs after erosion of Earth's surface?

masya89 [10]

Answer: Surface materials breaks down into smaller pieces.

Explanation:

Erosion is the geological process in which the topmost layer of the soil is worn away and transported by natural forces such as wind or water. A process which resembles erosion is weathering, which lead to breaking down or dissolution of rocks, but does not involve movement of the rock or soil materials.

After erosion the layers at the top of the soil are also broken down to smaller bits by factors such as water and winds.

What is the angle between the carbon-chlorine bonds in the phosgene ( cocl2 ) molecule?

lina2011 [118]

Answer: The angle between the carbon-chlorine bonds in phosgene will be 120°

Explanation: Formula used to calculate the hybridization:

${\text{Number of electron pairs}} =\frac{1}{2}[V+N-C+A]$

where,

V = number of valence electrons present in central atom i.e. carbon = 4

N = number of monovalent atoms bonded to central atom = 2

C = charge of cation = 0

A = charge of anion = 0

For $COCl_2$

${\text{Number of electron pairs}} =\frac{1}{2}[4+2-0+0]=3$

The number of electron pairs are 3 which means that the hybridization will be $sp^2$ and the electronic geometry of the given molecule will be trigonal planar.

The bond angle in this electronic geometry is 120°
