The density of copper is 8.92 g/cm3. What is the volume in L of a 230.14 mg sample of copper?

D=M/V so you plug in 8.92 for the density and 230.14 for the mass. then solve and get 25.8. you may need to do dimensional analysis with the different units of measures

It 32g of potassium nitrate can be dissolved in 1cm3 of water at 20oC before a saturated solution is obtained, how much potassiu
Dmitry_Shevchenko [17]

Answer:

160 gm

Explanation:

Five times as much water means you can dissolve 5 times as much potassium nitrate    5 x 32 = 160 gm  <u> <===== this seems unlikely though as I doubt 32 g  of  potassium nitrate will dissolve in only  1 cm^3 of water 1 cm^3 of water is only 1 gm of water </u>

6. Lysozyme is an enzyme that hydrolyzes sugar linkages in the bacterial cell wall and was first discovered by Alexander Fleming
balu736 [363]

Answer:

See explaination

Explanation:

The Cys3-cys97 and cys21-cys142 disulfides restrict the unfolded state of lysozyme enzyme to a class of more compact structures with a less exposed hydrophobic surface, compared to the unfolded states of reduced/non-crosslinked lysozyme. there are 2 major factors which lead to the stabilization of lysozyme due to disulfide bonds-

1- increase in the loop size due to the formation of disulfide bonds that leads to an increase in the even entropic effect.

2- the region formed should be flexible. the strain energy due to the formation of the disulfide bond is lower.

cys21-cys142 has a higher Tm than the cys3-cys97 because it involves flexible parts of the molecule. 21 and 142 residues are located on opposite sides of the active-site cleft where significant hinge-bending motion is seen. this introduces minimal strain in the protein.

Examine the nuclear reaction: 1 1 H+ 1 0 n -&gt; 2 1 H.
Lera25 [3.4K]
1) Conversion of an isotope one chemical element or an isotope into another chemical element is called as nuclear transmutation.
<span>
2) In a nuclear transmutation reactions</span> can be achieved either due to radioactive decay or  due to nuclear reactions. 

3) In this technique, it is possible to convert a stable element into radioactive atom by bombarding in with high speed particles. The initial stable nuclei is referred as parent nuclei, the fast moving particle is referred as projectile while new element which is formed is called as daughter element.

4) In the present reaction:
                                        <span>1 1 H+ 1 0 n -> 2 1 H
1 1H is a parent nuclei which is bombarded with the fast moving projectile
(1 0 n) to generate a new daughter nuclei (2 1H). </span>

If you react 156.0 g of calcium chloride with an excess NaOH, how much sodium chloride should you get?
laiz [17]

Answer:

164.3g of NaCl

Explanation:

Based on the chemical equation:

CaCl2 + 2NaOH → 2NaCl + Ca(OH)2

<em>where 1 mole of CaCl2 reacts with 2 moles of NaOH</em>

To solve this question we must convert the mass of CaCl2 to moles. Using the chemical equation we can find the moles of NaCl and its mass:

<em>Moles CaCl2 -Molar mass: 110.98g/mol-</em>

156.0g CaCl₂ * (1mol / 110.98g) = 1.4057 moles CaCl2

<em>Moles NaCl:</em>

1.4057 moles CaCl2 * (2mol NaCl / 1mol CaCl2) = 2.811 moles NaCl

<em>Mass NaCl -Molar mass: 58.44g/mol-</em>

2.811 moles NaCl * (58.44g / mol) = 164.3g of NaCl

How spectral lines are formed
Ket [755]

=Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…
