Which type of dry-chemical fixed application method introduces a concentration of agent into a closed area

Answers

Actuating mechanism is the dry-chemical fixed application method which

introduces a concentration of agent into a closed area.

The actuating mechanism is commonly used in piping systems and

involves the transport of a control member in automatic or remote control

systems.

The closed system makes manual navigation very difficult which is why the

actuating mechanism in automatic systems are usually used to make it less

tedious and accurate.

why does helium fusion require higher temperatures

Answers

Answer:

Nuclear fusion of hydrogen to form helium occurs naturally in the sun and other stars. It takes place only at extremely high temperatures. That's because a great deal of energy is needed to overcome the force of repulsion between the positively charged nuclei.

If i initially have a gas with a pressure of 84 kpa and a temperature of 350 c and i heat it an additional 230 degrees, what will the new pressure be? assume the volume of the container is constant.

Answers

Answer:

67.824

Explanation:  You want to use the combined gas law equation (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). So first cross out what remains constant, so volume(V) and I assume moles (since it was not mentioned as a change). Then you can solve algebraically for the answer!

Hope this helped!

The new pressure will be 139.2 kpa .

What is the combined Gas Law?

According to combined gas law,

[tex]\rm\dfrac{PV}{nT} = R[/tex]

In the Combined Gas Law,if we change either one of the variables the others will also change.

When the moles of the gas is constant , the above equation can be written as ,

[tex]\rm \dfrac{P'V'}{T'}= \dfrac{PV}{T}[/tex]

Given is P = 84kpa , T= 350⁰ C and T' = 350+230=580⁰ C , V=V' , P'=?

So we will substitute the values in the above formula keeping volume constant.

[tex]\rm \dfrac{P'}{T'}= \dfrac{P}{T}[/tex]

[tex]\rm\dfrac{P'}{580}= \dfrac{84}{350}[/tex]

[tex]\rm P' = \dfrac{84\times 580}{350}[/tex]

[tex]\rm P'= 139.2 \;kpa[/tex]

Therefore the new pressure will be 139.2 kpa .

Answer:

5.57 x 10^24 atoms

Explanation:

first, you are seeking the number of ATOMS of Boron.

Boron has an Atomic mass of 10.8 g/mol (see #5 on the periodic table)

100 gm of Boron would have 100 g /10.8 g/mol =9.26 moles

each mole has Avogadros number of atoms 6.02 x 10^23

9.26 moles has 9.26 x 6.02 x 10^23 atoms =5.57 x 10^24 atoms

The oxidation half equation is Zn ------> Zn^2+ + 2e while the reduction half equation is Cu^2+  + 2e------> Cu.

A redox reaction is a reaction in which there is a loss/gain of electrons. The specie that gives out electrons experiences an increase in oxidation number while the specie that gains the electrons experiences a decrease in oxidation number.

For the reaction; CuCl2 + Zn → ZnCl2 + Cu

The oxidation half equation is;

Zn ------> Zn^2+ + 2e

The reduction half equation is;

Cu^2+  + 2e------> Cu

The chloride ion is excluded because its oxidation number does not change from left to right in the reaction.

the factor that governs the formula of an ionic compound such as ca3n2 is

Answers

Answer:

the charge or oxidation number on the cation and anion.

Explanation:

The factor that governs the formula of an ionic compound such as Ca3N2 is the charge or oxidation number on the cation and anion.

In the example, Ca has a +2 charge, N has a -3 charge

So we need 3 x ( +2) to balance 2 x (-3) and have an electrically neutral compound, so

+6 -6 =0

The factor that governs the formula of an ionic compound such as Ca₃N₂ is charge.

What are ionic compounds?

Those compounds in which ionic bond is present between the cation and anion is known as ionic compound.

The most important factor that is essential for the formation of ionic compounds are charge i.e. positive charge and negative charge. In the given compound Ca₃N₂, Calcium (Ca) is present in the +2 oxidation state and Nitrogen is present in the -3 oxidation state. So due to attraction between these charges they make a ionic compound.

Hence charge is important factor.

Explanation:

They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.

Why are you more likely to become dehydrated in hot weather?

Answers

Answer:

sweat

Explanation:

you get dehydrated in hot weather because your body will release sweat to try and keep you cool

Answer:

Well, the heat can sometimes be very subtle in how it affects the body. If you're out in the sun, it can take just 30 minutes or up to a few hours for the heat to cause dehydration, nausea or it could cause trouble concentrating. When it's hot and humid, your risk of dehydration and heat illness increases. That's because when the air is humid, sweat can't evaporate and cool you as quickly as it normally does, and this can lead to an increased body temperature and the need for more fluids.

Answers

An observer in one of those galaxies see the other galaxy moving away at 400000 km/s.

Relative velocity is the velocity of an object with respect to another object, that is the time rate of change of relative position of one object with respect to another object.

Since two galaxy are moving in opposite directions with a velocity of 200,000 km/s. Hence the relative velocity between the two galaxies is 400000 km/s (200000 + 200000)

Therefore an observer in one of those galaxies see the other galaxy moving away at 400000 km/s.
