Identify each as measurement for area, volume, density, time, mass temp, length: ns, 12g/ml,
1.8pm, 250m2 ,325K and 5.4mL and 90kg

Answers

Answer 1

Answer:

ns - time

12g/ml - density

1.8pm - length

250m2 - area

325K - temperature

5.4mL - volume

90kg - mass

Explanation:

The unit of measurement is used to identify what a measurement is. It is very important to place a specific unit for each measurement made as it distinguishes them from one another. In this question, various measurements were given, which can be identified using their units.

- ns is measurement for time because seconds (s) is its unit

- 12g/ml is measurement for density because grams/milliliters (g/mL) is its unit

- 1.8pm is measurement for length because length can be measured in picometer (pm).

- 250m2 is measurement for area because metre² (m²) is its unit.

- 325K is measurement for temperature because Kelvin is the absolute unit for temperature.

- 5.4mL is measurement for volume because volume can be measured in milliliters (ml).

- 90kg is measurement for Mass because kilograms (s) is its unit.

5. The tradition of giving teachers an apple goes back to 19th century Denmark, where
teachers didn't earn enough for food. So, parents would send their children to school
with an extra snack for the teacher. Would current stdents' grades increase if they
brought in treats for their teachers?

Make a hypothesis help plz

Answers

Answer:

The apple, that innocent bud of an Americana autumn, has pulled off one of the greatest cons of all time. As students across the country prepare to greet a new school year and teacher with a polished bit of produce, the apple cements its place in the patriotic foods pantheon despite its dodgy past.

Answer:

If students brought an extra snack for their teachers it doesn't necessarily mean their grades would increase, but it's not impossible. A lot of teachers today might view it as being something like a suck-up. However, I do know that there are teachers who might be touched by such gestures and give the students extra attention, with this their grades might improve with the extra attention.

the pH value of 0.1 mol dm-3 of acid U is 1. Which statement is true about acid U?

A) slightly soluble in water
B) reacts only with a weak alkali
C) the degree of ionization in water is high
D) has a low concentration of hydrogen ions​

Answers

Answer:

the degree of ionization in water is high

Explanation:

The term pH is defined as the negative logarithm of hydrogen ion concentration.

Hence;

pH = -log[H^+]

The pH scale shows the degree of acidity or alkalinity of a solution. A solution of pH 1 is a strong acid. A strong acid dissociates completely in solution.

Hence, acid U has a high degree of ionization in water.

Is the following reaction feasible at 340K? Mg + ZnO -> MgO + Zn Enthalpy Data: Mg: 0 kJ/mol ZnO: -348 kJ/mol MgO:-602
kJ/mol Zn: 0 kJ/mol Entropy Data: Mg: 33 J/K mol ZnO: 44 J/K mol MgO: 42 J/K mol Zn: 27 J/K mol
A. No, it is not feasible because the Gibbs free energy change is negative.
OB. Yes, it is feasible because the Gibbs free energy change is negative.
C. No, it is not feasible because the Gibbs free energy change is positive.
D. Yes, it is feasible because the Gibbs free energy change is positive.

Answers

Answer:

No, it is not feasible because the Gibbs free energy change is positive

Explanation:

∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol

∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol

From;

∆G = ∆H - T∆S

∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]

∆G = 2.57 × 10^5 J/mol

Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.

Answer:

B. Yes, it is feasible because the Gibbs free energy change is negative.

codes for hair structure.
D. People with curly hair have different hair protein structures than people with
straight hair.
Answer here:

Answers

Answer:

A and D are the answers

Explanation:

the other two don't make sense

The statements C and D are correct, i.e., curly hair have different protein structure from straight hair and curly hair results from a change in the gene.

What is protein?

Proteins are biomolecules made of amino acids. Proteins are very essential to all living things and contributes the body structure. Proteins are mainly up taken through diet and they are the main source of energy.

Hair is made of keratin protein. Keratin makes up our skin and nails too.Curly hair is originating by birth not developing over time. Curly hair is more likely to be occurring through inheritance.

The protein structure the hair follicle is some more bend for curly hair. Curly hair and straight hair originates from different gene traits. The gene type is inherited from the parents.

Hence, for people with curly hair have different protein structure and it result from a change in gene that code for hair structure. Thus options C and D are correct.

Which option describes the structure of the electron shells in a neutral carbon atom? (1 point)
O The inner shell is complete with four electrons. The outer shell is incomplete with two electrons.
O The inner shell is incomplete with three electrons. The outer shell is incomplete with three electrons.
O The inner shell is complete with three electrons. The outer shell is incomplete with three electrons.
O The inner shell is complete with two electrons. The outer shell is incomplete with four electrons.

Answers

Answer:

The inner shell is complete with two electrons. The outer shell is incomplete with four electrons.

Explanation:

There can only be 2 electrons on the first (inner) shell, so it would be complete with two and there needs to be 8 electrons on the outer shell for it to be complete, so it would be incomplete with 4.

I'm having trouble understanding what "the difference in energy between the products and reactants from the surroundings" means. Can you help explain what this means? please​

Answers

Answer:

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.

Explanation:

Due to the absorption of energy when chemical bonds are broken, and the release of energy when chemical bonds are formed, chemical reactions almost always involve a change in energy between products and reactants. By the Law of Conservation of Energy, however, we know that the total energy of a system must remain unchanged, and that oftentimes a chemical reaction will absorb or release energy in the form of heat, light, or both.

In the above reaction, the number of elements on the reactant side are;

4 carbon, C, atoms, 10 hydrogen, H, atoms, and 13 oxygen, O, atoms

The number of elements on the product side of the above chemical reaction are;

The number of carbon atoms, C = 4

The number of hydrogen atoms, H = 10

The number of oxygen atoms, O = 13

Therefore, the number of atoms on the reactant side of the chemical equation are equal to the number of atoms on the product side, and the combustion reaction for isobutane is balanced.
