The addition of an acid to water increases the [H30*) of the solution and increases the solution pH.

Consider the Lewis structure for glycine, the simplest amino acid: (a) What are the approximate bond angles about each of the tw

UkoKoshka [18]

Each carbon is tetrahedrally planar and has three sections, making all bond angles in (a) 120°.(b) hybridization with sp2.(c) If a double bond is present in the compounds, one of the bonds is a sigma connection and the other a pi bond.

<h3>What is an example of an amino acid?</h3>

A basic amino group (NH2), a carboxyl group group (COOH), and an organic Aromatic rings that really is specific to each amino acid make up an amino acid, an organic molecule.

<h3>Which five amino acids are there?</h3>

You must obtain the nine essential amino acids cytochrome c, isoleucine, hcl, lysine, methionine, phenylalanine, alanine, tryptophan, and valine through your food.They are essential for several bodily processes, such as protein biosynthesis, tissue regeneration, and nutrient uptake.

A gas company in Massachusetts charges $1.30 for 15.0 ft^3 of natural gas. (a) Convert this rate to dollars per liter of gas. (b

aleksley [76]

Answer:

Explanation:

a ) 15( ft)³ = 15 ( 12 inch )³ = 15 x 12 x 12 x 12 (inch)³ = 25920 (inch)³

=25920( 2.54 cm)³ = 25920 x 2.54 x 2.54 x 2.54 cm³ =424752.7 cc

424752.7/1000 litre = 424.75 liter

424.75 liters cost 1.30 dollars

1 liter costs 1.3/424.75 = 3.06 x 10⁻³ dollars.

So rate

= 3.06 x 10⁻³ dollars/liter

b ) one liter of water takes 0.304 ft³ of gas

2.1 liter will take 0.304 x 2.1 = 0.6384 ft³ of gas

cost = 1.3 x .6384 / 15 = 0.055328 dollar = 55.33 x 10⁻³ dollar.

rubidium-83 is an element that can undergo electron capture to form a more stable nuclide. which of the isotopes below is formed

Rasek [7]

The krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.

What is isotopes?

isotopes are defined as atoms with a constant number of protons but a variable number of neutrons. Despite having different masses and hence having different physical qualities, they have nearly identical chemical properties.

What is stable nuclide?

Since stable nuclides are not radioactive, they do not spontaneously decay into radioactive elements as happens with radionuclides. They are commonly referred to as stable isotopes when such nuclides are discussed in connection to particular elements.

The electron capture process will turn rubidium-83 into krypton-83. When a proton in the nucleus catches an inner electron and creates a neutron, this process is known as electron capture.

Therefore, krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.

If 7.25g of chlorine is reacted with excess hydrogen and produces 7.25 g HCl. What is the percent yield?

lozanna [386]

Answer:

94.61 %

Explanation:

percent yield = (actual yield / theoretical yield) X 100%

The balanced equation for the reaction is:

H2 (g ) + Cl2(g) => 2 HCl (l)

So, the theoretical yield =

7.25g of chlorine X (2mol of Cl / 35.453 g of Cl) X (2mol Cl / 2mol of HCl) X 37.469g of Hcl / 2mol of Hcl = 0.409 x 18.735 = 7.663g of Hcl

Using this theoretical yield and the provided value for actual yield, the percent yield = (actual yield / theoretical yield) X 100%

= (7.25 g / 7.663g) X 100

= 94.61 %
