The reaction is a synthesis reaction.

<h3>What are synthesis reactions?</h3>

Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.

Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.

The different elements that combine are referred to as the reactants while the result of the combination is known as the product.

For example: A + B --> AB

In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.

This is a good example of a synthesis/combination reaction.

Mass defect is associated with:

gizmo_the_mogwai [7]

Answer:

B. Nuclear fission

Explanation:

Nuclear binding energy is used to determine whether fission or fusion will be a favorable process. The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.

Determine the magnitude of the acceleration experienced by an electron in an electric field of 664 N/CN/C .

VARVARA [1.3K]

Answer:

$a=-1.17\times 10^{14} \hspace{3}\frac{m}{s^2}$

Explanation:

A charged particle that is in a region where there is an electric field, experiences a force equal to the product of its charge by the intensity of the electric field:

$F_e=q*E$

If the electric field is uniform, the force is constant and so is the acceleration. Applying the equations of uniformly accelerated rectilinear motion, we obtain the velocity of the particle at any time or after having moved a certain distance:

$a=\frac{qE}{m}$ (1)

Where:

$E=Electric\hspace{3}field\hspace{3}strength=664\frac{N}{C} \\q=Electric\hspace{3}charge\hspace{3}of\hspace{3}the\hspace{3}particle\\m=Mass\hspace{3}of\hspace{3}the\hspace{3}particle$

The electric charge and the mass of the electron are known constants:

$q=-1.6\times 10^{-19} C\\m=9.1\times 10^{-31} kg$

So, replacing this data in the equation (1) :

$a=\frac{(-1.6\times 10^{-19})*(664) }{9.1\times 10^{-31} } =-1.167472527\times 10^{14} \approx -1.17\times 10^{14} \hspace{3}\frac{m}{s^2}$

The minus sign is due to the fact that the charge is negative, therefore it experiences a force in the opposite direction to the field.

Rank the following groups in order of decreasing priority: A. bondCtbondCH B. bondCH(CH3)2 C. bondCH2CH3 D. bondCHdbondCH2

Lelu [443]

Answer:

(CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3

Explanation:

Giving the following ; CH3, CH2CH3, CH2CH2CH3, (CH2)3CH3

Priority increases as the number of CH2 group increases and vice versa, as such the one with more CH2 group will be the highest priority and the least compound with the small CH2 group attached, will have the smallest priority.

The arrangement is as follows ; (CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3

Explain why space junk is a hazard to an astronats or spacecraft

Pie

Answer:

Space junk is travelling so fast that a collision with an astronaut or a spacecraft could be disastrous.

Explanation:

Space junk orbits the Earth at speeds of about 28 000 km/h.

That's so fast that even an orbiting fleck of paint has enough kinetic energy to cause impact craters on the surface of a spacecraft. They are even more dangerous to an astronaut on a space walk.

Much of the space debris is larger and more dangerous than a fleck of paint.

One rough estimate of the amount of space debris is

<em> </em><u>Size</u><em> </em> <u>Number of objects</u>

< 1 cm 200 000 000

1 cm to 10 cm 700 000

> 10 cm 30 000

Satellites, etc. 18 000

The chances of collision are small, but any collision can be disastrous.
