D. Adding more of the chemical will heat the water but only up to a certain temperature

<h3>Further explanation</h3>

Chemical changes are changes in the process that produce new substances that are different from the initial/ forming substances. Chemical changes are usually known as chemical reactions. So there are products/reactions and reactants and there is a change in the molecule/particle

The chemical reaction is usually followed by the release of heat, gas, change in color, precipitate substance etc

The heat that occurs in the addition of chemicals is caused by the reaction with water. But there is a constant rise in temperature when water reaches <em>its maximum capacity to react with these chemicals.</em>

Evidenced by the addition of 15 g and 20 g of chemicals, the temperature changes are constant

chubhunter [2.5K]

Answer:

Primary structure is the correct answer.

Explanation:

The primary structure is the simple level of protein structure.

Primary structure is a basic amino acids sequences in a protein.

In the primary structure, amino acids are attached together by a covalent bond.
Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains

Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.

What are the moles of gas are in a 30 liter scuba canister if the temperature of the canister is 300 K and the pressure is 200 a

Lady_Fox [76]

Answer:

$n = 243.605$

Explanation:

Given

$Pressure, P = 200\ atm$

$Temperature, T = 300k$

$Volume, V = 30L$

Required

Calculate the number of moles

We'll apply the following formula to solve this question

$n = \frac{pV}{RT}$

Where

$R = 0.0821 L\ atm/(mol\ K)$

The above equation is an illustration of the ideal gas law

Substitute values for p, V, R and T in:

$n = \frac{pV}{RT}$

$n = \frac{200 * 30}{0.0821 * 300}$

$n = \frac{6000}{24.63}$

$n = 243.605$

<em>Hence, there are 243.605 moles</em>

An atom of which of these elements most likely forms an anion? A. AI B. Br C. Ca D. Mg

Papessa [141]

The answer is B. A good way determine this is how far right the element is on the periodic table. The further right the element is, the more electronegative it is meaning it is more willing to accept an electron. This can be explained using the valence electrons and how many need to be added or removed to complete the octet. The further right you are, the easier it is for the element to just gain a few electrons instead of loose a bunch. Noble gases are the exception to this since they don't normally react though.
