Cerrena [4.2K]2 years ago
7 0

Explanation:

2moles of NaOH -> 2moles of H2O

so the number of moles r equal.

hence moles of H2O is 12.5

Peyote has effects similar to those of __________, but with different types of hallucinations.
prisoha [69]

Peyote has similar effects with that of LSD but with different hallucinations.

LSD is a hallucinogen that is chemically synthesized. It is developed from ergot which is a kind of mold that can be found on the rye grain. Getting high on acid (LSD) or also known as acid trip or psychedelic experience creates visual and sensory distortions, a change in thought processing, intense emotions like that of euphoria and on some people a derivation of surprising new insights.

Mescaline or peyote is a naturally occurring psychedelic substance that is found in a specific cactus species known as peyote cactus. In terms of hallucination, the user sees or hears things that are not there and have no actual basis in reality. Hallucinations that occurs during mescaline intoxication are often unreal that can cause distress and confusion.

What is the bronsted acid of NO2- + H2O HNO2 + OH-​
sammy [17]
<h3><u>Answer</u>;</h3>

H2O -Bronsted Acid

<h3><u>Explanation;</u></h3>
  • Bronsted-Lowry acids are  H+ donors , while Bronsted-Lowry bases are H+ acceptors .
  • A reaction of a Bronsted-Lowry acid and a Bronsted base is a neutralization reaction that is characterized by H+ transfer.
  • The above reaction is an example of base ionization or dissociation where;

                 B (aq) + H2O (l) → BH+ (aq) + OH– (aq)

          That is; Base + Acid will give a conjugate acid + hydroxide ion

  • In our case; NO2- + H2O → HNO2 + OH-​ ; H2O is the H+ donor and thus, it is a Bronsted Acid.

Nutritional biochemists have known for decades that acidic foods cooked in cast-iron cookware can supply significant amounts of
podryga [215]

The number of ferrous ions present in jar are 3.1x 10^21.

<h3>Steps</h3>

Since we have 737 g, 5,896 servings are generated.

If one serving contains 49 mg of iron, then one can contains 49*5,896 mg of iron.

In other words, if made in a cast-iron pot, one jar of tomato sauce has 288,9 mg of iron.

The number of ferrous ions present in jar are 3.1x 10^21.

<h3>What exactly does nutritional biochemistry mean?</h3>

Nutritional biochemistry is the study of nutrition as a science that deals with physiology, medicine, microbiology, pharmacology, chemistry, and biology and uses these sciences for the investigation of health, diet, and nutrition as well as the research of disease and the administration of medications.

<h3>What does nutritional biochemistry teach you?</h3>

This covers a fundamental knowledge of molecular genetics, biostatistics, epidemiology, and metabolism. Learn the laboratory skills necessary for current biochemical and molecular investigations into diet and its impact on health and illness.

A solution was made by dissolving 5.10 mg of hemoglobin in water to give a final volume of 1.00 ml. the osmotic pressure of this
Assoli18 [71]

The molecular weight of hemoglobin can be calculated using osmotic pressure

Osmotic pressure is a colligative property and it depends on molarity as

πV = nRT

where

π = osmotic pressure

V = volume = 1mL = 0.001 L

n = moles

R = gas constant = 0.0821 L atm / mol K

T = temperature = 25°C = 25 + 273 K = 298 K

Putting values we will get value of moles

moles=\frac{\pi V}{RT}=\frac{0.00195X0.001}{0.0821X298}mol

we know that

moles=\frac{mass}{molarmass}

Therefore

molarmass=\frac{mass}{moles}=\frac{5.10X10^{-3}g}{7.97X10^{-8}}=6.399X10^{4}g
