True/False. A characteristic of a good cardiac biomarker is that it is normally present in a HIGH concentration in the peripheral blood.

Answers

Answer 1

Good cardiac biomarkers typically have a HIGH concentration in the peripheral blood, which is one of their distinguishing traits.

A biomarker that accurately predicts heart injury is one that is normal. The cardiac biomarker levels in your blood are determined by this test. Enzymes, hormones, and proteins are some examples of these markers. After your heart has been put under a lot of stress and has become harmed from not getting enough oxygen, cardiac biomarkers become visible in your blood. This could be the result of a heart attack.

Cardiac indicators are biomarkers that can be used to assess heart health. They may be helpful in the early diagnosis or prediction of disease. Even though they are frequently mentioned in relation to myocardial infarction, other diseases can cause an increase in cardiac.

The Universal Space Agency wants to know the results of your Sim investigation. Write your report to the lead chemist, explaining why there is liquid water on the outside of the can but no liquid nitrogen. Use evidence from your investigation in your explanation.

Answers

Answer:

Due to warm temperature.

Explanation:

There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.


it is used to lift water from a well​

Answers

Answer:

When air is admitted into the well, the water recedes from the level of static head to the bottom of the discharge pipe. The displaced column of liquid rises up the discharge pipe. Air bubbles mix with water and this reduces the specific gravity of the column of water sufficiently to lift it to the surface.

What is the mass in grams of 9.02x10^28 atoms of Fe​

Answers

Answer:

83.674 grams of Fe

Explanation:

9.02 x 10²⁸ atoms

To convert from atoms to grams, we first need to convert atoms to moles. To do this, divide the atoms by Avogadro's Number, 6.02 x 10²³

9.02 x 10²⁸ ÷ 6.02 x 10²³

= 1.498 moles of Fe

Now we need to convert moles to grams. To do this, multiply the moles by the molar mass of Fe. The molar mass can be found on the periodic table.

1.498 • 55.845

= 83.674 grams of Fe

A student performs an acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice. Which solution should the student use as the base solution in this acid-base titration experiment?

Answer:

The answer is Option B, NaOH is the solution student should use as the base solution in this acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice.

What is an Acid Base Titration ?

An acid–base titration is a method of quantitative analysis.

It is used for determining the concentration of an acid or base by neutralizing it with a standard solution of base or acid of known concentration.

An indicator is used to monitor the progress of the acid–base reaction.

Ascorbic acid, HC₆H₇O₆ is an acid. So can be titrated with a base , sodium hydroxide, NaOH using the indicator, phenolphthalein.

HC₆H₇O₆(aq) + NaOH(aq) → NaHC₆H₇O₆(aq) + H₂O(l)

Among the options , HCl is an acid , LiBr , CaCl₂ are salts , NaOH is the only base.

Phenolphthalein changes from colorless to pink (or red) when all of the acid gets neutralized.

Therefore NaOH is the solution student should use as the base solution in this acid-base titration experiment to determine the amount of ascorbic acid in different brands of juice.

how would you prepare 500 ml of a .50m solution of naoh from a 2 m stock solution

Answers

Explanation:

i.e M = m/V(L)

M= Molarity of substance

m = number of moles of substance (i.e solute)

V(L) = volume of solution in Litres

So talking about our question molarity should be 0.5 M,volume should be 0.1 L , and we should know that Molar Mass of NaOH is 40 because Atomic mass of Sodium i.e (Na known as Natrium) is 23,Atomic mass of Oxygen (O) is 16 and Atomic mass of Hydrogen is 1.

Adding them all up gives Molecular mass of NaOH as 40

So if we solve above equation we get no of moles of NaOH present in 0.1 litres of solution

Let’s do that math

Rearranging equation we get m=M×V(L) i.e m= 0.5×0.1 =0.05. So 0.05 moles of NaOH are present in 100 ml of 0.5 Molar solution

Now we also know that to find no of moles of a substance we have a formula and it is m=W/Mw where

m = no of moles of a substance

W = Mass of substance

Mw = Molecular weight of the substance

So substituting all values and rearranging equation we get mass of NaOH as

W=m×Mw = 0.05×40=2 grams

Hence we found the required mass of NaOH as 2 grams.

Now talking about shortcut

we know as explained above M=m/V(L) and m=W/M

Substituting value of m(no of moles) in M=m/V(L) we get M=WMw×V(L)

Try substituting the values yourself and get the answer

Note :: The value of Volume should always be substituted in terms of Litre only. That is the reason i used the letter (L) at all the places with V

So thats all get the answer and comment any other problems below

how many moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​

Answers

Answer:

10 moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​.

Explanation:

The balanced reaction is:

N₂ + 3 H₂ → 2 NH₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

N₂: 1 moleH₂: 3 molesNH₃: 2 moles

Then you can apply the following rule of three: if by reaction stoichiometry 1 mole of nitrogen produces 2 moles of ammonia, 5 moles of nitrogen produces how many moles of ammonia?

[tex]moles of ammonia=\frac{5 moles of nitrogen*2 moles of ammonia}{1 mole of nitrogen}[/tex]

moles of ammonia= 10

10 moles of ammonia could be obtained from a maximum of 5.0 moles of nitrogen​.

A gas has a volume of 5.00 L at 20 degrees Celsius. What is the volume of gas at 150 degrees Celsius.

Answers

Answer:

7.22 L

Explanation:

From the question,

Applying Charles law,

V₁/T₁ = V₂/T₂...................... Equation 1

Where V₁ = Initial volume of gas, V₂ = Final volume of gas, T₁ = Initial Temperature of gas in Kelvin, T₂ = Final Temperature of gas in Kelvin

Make V₂ the subject of the equation

V₂ = (V₁×T₂)/T₁................. Equation 2

Given: V₁ = 5.00 L, T₁ = 20 °C = (20+273) K = 293 K, T₂ = 150 °C = (150+273) K = 423 K

Substitute these value into equation 2

V₂ = (5.00×423)/293

V₂ = 7.22 L
