The new pressure is 81.675 torr

Since temperature and moles are held constant, we use Boyle's Law:

A gas law known as Boyle's law asserts that a gas's pressure is inversely proportional to its volume when it is held at a fixed temperature and of a given mass.

To put it another way, as long as the temperature and volume of the gas remain constant, the pressure and volume of the gas are inversely proportional to one another.

The Anglo-Irish chemist Robert Boyle proposed Boyle's law in the year 1662.

P1V1=P2V2. Simply plug in your values. The units can remain in torr. Converting to atmospheres is not needed.

(242 torr)(27.0 L)=P2(80.0 L)

P2=[(242)(27)]/80 = 81.675 torr

Hence The new pressure is 81.675 torr

Write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate. identify the ox
asambeis [7]

Well in this case, silver nitrate is reduced:

Ag<span>+  </span><span>+  </span>e<span>−  </span>→ Ag(s) ↓

 

Meanwhile, the aluminum is oxidized forming a positive ion:

Al(s<span>)  →  </span>Al<span>3+  </span><span>+  3</span>e−

 

To get the overall reaction,  we add the half equations so that the electrons are eliminated:

Al(s<span>)  +   3</span>Ag<span>+  </span><span>→  </span>Al<span>3+  </span><span>+  3</span>Ag(s)

 

And similarly:

Al(s<span>)  +  3</span>AgNO3(aq<span>)  →  </span>Al(NO3)3(aq<span>)  +  3</span>Ag(s<span>)</span>

On a coordinate plane, which single transformation could map point A (3,-4) onto point A' (1.5,-2)? *
Ksenya-84 [330]

Answer: A dilation with rule: (x,y)\to(\dfrac12x,\dfrac12y)

Explanation:

A dilation is a non-rigid transformation that creates an image that is the same shape as the original but has a different size.

It uses a scale factor k such that

(x,y)\to(kx,ky)

(x,y)= coordinates of original figure

(kx,ky) = corresponding coordinate in the image.

To transform: A (3,-4) onto point A' (1.5,-2).

Using scale factor k= \dfrac12, we have

A(3,-4)\to A'(\dfrac12\times3, \dfrac12\times-4)=A'(1.5,-2)

Required rule: (x,y)\to(\dfrac12x,\dfrac12y)

F a shell can hold a maximum of 32 electrons, what is the value of n? 2 3 4 5
Arte-miy333 [17]

Answer: 4

Explanation:

Principle Quantum Numbers: This quantum number describes the size of the orbital. It is represented by n.

Azimuthal Quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number: This quantum number describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from (-l\text{ to }+l). When l = 2, the value of m_l will be -2, -1, 0, +1, +2.

Given : a f subshell, thus l = 3 , Thus the subshells present would be 3, 2, 1, 0 and thus n will have a value of 4.

Also electrons give are 32.

The formula for number of electrons is 2n^2.

2n^2=32

n=4

Thus principal quantum no will be n= 4.
