What is the answer to Isotope 3?

Answer:

Insulin production would decrease.

Explanation:

Insulin and Glucagon work together to balance the sugar levels in the human blood stream. They work together in a negative feedback loop. Glucagon stimulates the liver to release glucose into the bloodstream in a process known as glycogenolysis. Insulin on the other hand is a sugar-lowering hormone.

Therefore, if glucagon secretion were permanently inhibited, insulin production would decrease as there would not be excess blood sugar to be reduced.

Answer:

Insulin production would decrease.

Answer:

The possible valances can be determined by electron configuration and electron negativity

Good Luck even though this was asked 2 weeks ago

Explanation:

All atoms strive for stability. The optima electron configuration is the electron configuration of the VIII A family or inert gases.

Look at the electron configuration of the nonmetal and how many more electrons the nonmetal needs to achieve the stable electron configuration of the inert gases. Non metals tend to be negative in nature and gain electrons. ( They are oxidizing agents)

For example Florine atomic number 9 needs one more electron to reach a valance number of 8 electrons to equal Neon atomic number 10. Hence Flowrine has a valance of -1

Oxygen atomic number 8 needs two more electrons to reach a valance number of 8 electrons to equal Neon atomic number 10. Hence Oxygen has a valance charge of -2.

Non metals with a low electron negativity will lose electrons when reacting with another non metal that has a higher electron negativity. When the non metal forms an ion it is necessary to look at the electron structure to determine how many electrons the element can lose to gain stability.

For example Chlorine which is normally -1 like Florine when it combines with oxygen can be +1, +3, + 5 or +7. It can lose its one unpaired electron, or combinations of the unpaired electron and sets of the three pairs of electrons.

Answer:

[tex]4.13[/tex] x [tex]10^{2}[/tex] = 413 kg

Explanation:

4.13 x 10 = 41.3 then we multiply 41.3 by 10 agian = 41.3 x 10 = 413

so, we multiplied ten two times that = [tex]10^{2}[/tex]

= 4.13 x [tex]10^{2}[/tex]= 413 kg

Given that 1 kilogram = 1000grams, the value of 413 kilograms in grams, using scientific notation is 4.13 × 10⁵g.

Note that;

1 kilogram = 1000grams

Given that;

Since, 1 kilogram = 1000grams

413 kilograms = ( 413 × 1000 )grams

413 kilograms = ( 413000 )grams

413 kilograms = 4.13 × 10⁵ g

Given that 1 kilogram = 1000grams, the value of 413 kilograms in grams, using scientific notation is 4.13 × 10⁵g.

Answer:

Specific gravity compares the density of a substance to the density of air.

Specific gravity is compared the density of a substance to the density of water.

Specific Gravity is a dimensionless quantity that can be defined as the ratio of the density of a substance to the density of the water at a particular temperature.

The mathematical formula of the specific gravity can be written as:

Specific gravity = density of substance / density of water

The density of water at 4°C is used as a reference point as water has the highest density of 1000 kg/m³.  Specific gravity or relative gravity does not have any dimension as it is a dimensionless quantity.

Specific gravity is the ratio of a substance’s density to that of water at a specific temperature. The temperature plays an important role in determining the specific gravity of a substance.

Therefore, specific gravity is a characteristic of the substance at a particular temperature and pressure that also affects the specific gravity.

pOH of a solution = 5.95

Given

The concentration of hydronium ions : 8.9 x 10⁻⁹

Required

pOH

Solution

pOH = - log[OH]​

[H₃O⁺]= 8.9 x 10⁻⁹

pH = - log[H₃O⁺]

pH = 9 - log 8.9

pH = 8.05

pH + pOH = 14

pOH = 14-pH

pOH= 14-8.05

pOH = 5.95

Answer:

The total air pressure at the top of the highest peak in the world is 253.5 torr

Explanation:

The partial pressures of the gases present at the top of Mount Everest are;

Nitrogen, N₂ = 201.0 torr

Oxygen, O₂ = 50.0 torr

Argon, Ar = 2.0 torr

Carbon dioxide, CO₂ = 0.5 torr

By Dalton's law of partial pressure, the total pressure that a mixture of gases exerts is equal to the sum of the partial pressures of the individual gases

Mathematically, the law can be expressed as follows;

Total pressure, P = ∑P[tex]_i[/tex] = P₁ + P₂ + · · ·

From which we have;

The total air pressure at the top of the highest peak in the world, Mount Everest, [tex]P_{Total Mont Everest}[/tex] = The sum of the partial pressures of N₂, O₂, Ar, and CO₂

[tex]P_{Total Mont Everest}[/tex] = 201.0 torr + 50.0 torr + 2.0 torr + 0.5 torr = 253.5 torr

[tex]P_{Total Mont Everest}[/tex] = 253.5 torr = 0.33355263 atmosphere

Therefore, the total air pressure at the top of the highest peak in the world,  [tex]P_{Total Mont Everest}[/tex] = 253.5 torr

The total air pressure at the top of the highest peak in the world is 253.5 torr.

Dalton's law of gases states that total pressure of any mixture of gases is equal to the sum of the partial pressures of individual gases.

Given that,

Partial pressure of Nitrogen gas = 201 torr

Partial pressure of Oxygen gas = 50 torr

Partial pressure of Argon gas = 2 torr

Partial pressure of Carbon dioxide gas = 0.5 torr

Total pressure at the top = 201 + 50 + 2 + 0.5 = 253.5 torr

Hence total pressure is 253.5 torr.

Explanation:

Given data:

Number of atoms of cobalt = 3.31 × 10²² atoms

Mass of cobalt atoms  = ?

Solution:

We will calculate the number of moles of cobalt by using Avogadro number.

1 mole contain 6.022× 10²³ atoms

3.31 × 10²² atoms  × 1 mol / 6.022× 10²³ atoms

0.549 mol × 10⁻¹

0.0549 mol

Mass of cobalt:

Mass = number of moles × molar mass

Mass = 0.0549 mol × 58.93 g/mol

Mass = 3.24 g

Answer:

V₂ = 1.41 L

Explanation:

Given data:

Initial temperature = 35°C (35 +273.15 K = 308.15 K)

Initial volume = 1.5 L

Final temperature = 17°C (17+273.15 K = 290.15 K)

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 1.5 L × 290.15 K / 308.15 k

V₂ = 435.23 L.K / 308.15 k

V₂ = 1.41 L

Explanation:

The activity or electrochemical series is an arrangement of elements according to their order

of reactivity.

If we look at the reactions, one thing that we must note is that the reactions that can occur are those in which an element that is higher in the series displaces another element that is lower in the series.

Br is higher in the electrochemical series than I so it can displace it. Ni is higher than Ag in the electrochemical series hence it can displace it.

We already know that the original substance was pure. If this substance was pure and it was powdery in nature then we have a footing to start from.

Secondly, a 4.93 g of shinny metallic liquid was left behind. This shinny metallic liquid must be an element.

Since there was a loss in mass during heating, it follows that there were other components of the pure powder.

Answer:

920mL of water

Explanation:

To solve this question we need to find as first the mass that must be added of water to make 1000mL of syrup using specific gravity. Thus, we can know the volume of water that mus be added:

1.31 is 1.31g/mL. In 1000mL = 1310g/1000mL. As the mass added of sucrose is 850g, the mass of water = Volume of water is:

1310g - 850g = 460g of water = 460mL to make 1L, To make 2L the amount of water that must be added is:

460mL * 2  =

The number of milliliters of water are used to prepare two liters of syrup is 920 mL of water.

Given that,

Based on the above information, the calculation is as follows:

1.31 is = 1.31g/mL.

Now

In 1000mL = [tex]1310g \div 1000mL[/tex].

Now if the mass is added so the mass of water should be equivalent to the volume of the water.

= 1310g - 850g

= 460g of water

Now

= 460mL for 1L,

To make 2L the water should be  

= 460mL (2)

= 920mL of water
