Answer:
The acid base imbalance would be metabolic acidosis.
Explanation:
Metabolic acidosis is a systemic failure that can occur from various causes, from an uncompensated diabetic with an excess of ketone bodies in the blood, to poisoning with CO2.
This is regulated and compensated by the respiratory system that seeks to eliminate CO2 through the respiratory tract in order to increase the alkalinity of the blood.
This system is highly accompanied by renal aid that is responsible for excreting acid metabolites and retaining fluids for the dissolution of acidosis.
On the other hand, in patients who suffer from this systemic failure, it will be noticed as a very characteristic symptom of hypercapnia and hyperventilation, since the respiratory system is in charge of increasing the frequency to quickly decrease this acidosis and that the low blood pH do not denature the proteins critical to vital signs.
is the biosphere contains only non-living thing true or false
Answer:
False
Explanation:
It’s both living and non living
Answer:
False
Explanation:
In biospheres, there are both living and nonliving objects present! There are typically large abundances of living objects, such as animals, trees, grass, etc. There are also nonliving objects included in biospheres that are necessary for the prosperity of the living creatures! Examples of these nonliving objects include water for hydration, air for breathing, soil for growth, etc. A biosphere is where all living things are found on Earth, so the question is false since both types of things are found within them and not just nonliving things!

Answer:
Mass = 5.24 g
Explanation:
Given data:
Number of atoms of Ca = 7.9×10²² atoms
Mass of Ca = ?
Solution:
First of all we will calculate the number of moles by using Avogadro number.
1 mole contain 6.022×10²³ atoms
7.9×10²² atoms × 1 mol /6.022×10²³ atoms
1.31 ×10⁻¹ mol
0.131 mol
Mass of Ca:
Mass = number of moles × molar mass
Mass = 0.131 mol × 40 g/mol
Mass = 5.24 g
Used in ur own words, How are elements,compounds,and mixtures different?
Explanation:
Elements are pure substances made up of only atoms that all have the same number of protons in their nuclei. Compounds are molecules held together by covalent bonds. Ionic compounds are held together by ionic bonds. Intermetallic compounds are held together by metallic bonds. Certain complexes are held together by coordinate covalent bonds. A mixture is a combination of two or more elements or compounds which haven't bonded yet, so each mixture is it's own.
Hope this helps!

At a depth of 100 ft in water, the external pressure is 4.0 atm. What is the solubility of N2 from air in blood at this pressure
Answer:
Solubility = 2.142 x [tex]10^{-4}[/tex] M
Explanation:
Solution:
Note: This question is incomplete and lacks necessary data to solve this question. But I have found similar question on the internet and fetched the necessary data to solve:
Missing Data:
Number of Moles of N2 dissolved per litre of blood = 5.357 x [tex]10^{-4}[/tex] M
As we know that, the air is approximately. 78 mol % of N2
N2 = 0.78
Partial pressure of the N2 at 100 ft:
Partial Pressure = 0.78 x (4.0)
Partial Pressure = 3.12 atm
Now, this is 4 times the pressure of nitrogen at 1 atm air pressure.
SO,
According to the Henry's Law, we have:
Solubility = k x [tex]P_{g}[/tex]
Here, k = 4 times
So,
Solubility = 4 x (5.357 x [tex]10^{-4}[/tex])
Solubility = 2.142 x [tex]10^{-4}[/tex] M
What happens to the particles in dry ice when it subimes
Answer:
The particles in dry ice overcomes the force of attraction between them to change directly to gaseous state.
Explanation:
Matter exists in three states- solid, liquid and gas. When heated, solid changes to liquid and then gas. However, upon condensation, gas changes to liquid and then to solid. Some solids when heated change directly to vapour without an intermediate liquid state, such vapour will also condense to solid without going through the liquid state. Example includes: ammonium chloride, iodine crystals and sulphur. These solids undergo SUBLIMATION.
Dry ice which is also known as solid frozen carbon dioxide can undergo sublimation when subjected to -78°C. What actually happens to the particles ( molecules) of the frozen carbon dioxide is the existence of weak intermolecular forces between the molecules. Since the molecules are very weakly attracted to each other, frozen carbon dioxide molecules very readily go from the solid state to the gas state at low temperatures.

If a 12-volt battery produces a current of 20 amps, what is the resistance?
Answer:
0.6 Ω
Explanation:
From the question given above, the following data were obtained:
Voltage (V) = 12 V
Current (I) = 20 A
Resistance (R) =?
From Ohm's law,
V = IR
Where:
V => is the voltage
I => is the current
R => R is the resistance
With the above formula, we can obtain the resistance as follow:
Voltage (V) = 12 V
Current (I) = 20 A
Resistance (R) =?
V = IR
12 = 20 × R
Divide both side by 20
R = 12 / 20
R = 0.6 Ω
Thus the resistance is 0.6 Ω

In order to carbonate soda, soda companies have to compress carbon dioxide close to 1250 mL of carbon dioxide at a pressure of 1.00 atm into a can with a volume of 225 mL. What is the pressure of carbon dioxide inside the soda can?
HELPPPPPPPP
Answer:
Pressure inside soda can = 5.56 atm
Explanation:
Given data:
Initial volume = 1250 mL
Initial pressure = 1.00 atm
Final volume = 225 mL
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.00 atm × 1250m L = P₂ × 225 mL
P₂ = 1250 atm. mL/ 225 mL
P₂ = 5.56 atm

A crest of a wave with an amplitude of 3 meters intersects with another trough of a wave with an amplitude of 2 meters. What is the resulting amplitude?
3 meters
2 meters
6 meters
1 meter
Answer:
A 3 meters
Explanation:
A crest of the wave is the highest peak in the wave that shows the maximum displacement value. The intersection of the 3-meter and 2-meter waves results in amplitude of 1 meter. Thus, option D is correct.
What is amplitude?The amplitude of the wave is the measurement of the wave from the still position towards the crest or the trough of the wave. It is estimated in meters.
The elevation of the wave is at 3, and the depression is at 2 meters when intersected, which results in an amplitude causing destructive interference. As 3 m is above the baseline and 2 m is below the baseline the resulting amplitude will be, 3 - 2 = 1 m.
Therefore, the resulting amplitude is 1 meter.

How much sodium chloride is produced from the synthesis of 100g of sodium and an excess of chlorine gas? 2Na + Cl2= 2NaCl
Answer:
254.35 g of NaCl.
Explanation:
We'll begin by writing the balanced equation for the reaction between sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl). This is illustrated below:
2Na + Cl₂ —> 2NaCl
Next, we shall determine the mass of Na that reacted and the mass of NaCl produced from the balanced equation. This can be obtained as follow:
Molar mass of Na = 23 g/mol
Mass of Na from the balanced equation = 2 × 23 = 46 d
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g
SUMMARY:
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
Finally, we shall determine the mass of NaCl produced by the reaction of 100 g of Na. This can be obtained as follow:
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
Therefore, 100 g of Na will react to produce = (100 × 117)/46 = 254.35 g of NaCl.
Thus, 254.35 g of NaCl were obtained from the reaction.
Which element could provide one atom to make an ionic bond with oxygen?
Answer:
Magnesium
Explanation:
The element that could provide one atom to make an ionic bond with oxygen is magnesium.
Generally, most group II elements will form an ionic bond with oxygen with just one atom.
An ionic bond forms by the transfer of electrons from one specie to another.
Oxygen has a charge of 2-, to use one atom to form ionic bond with this specie, a magnesium atom with 2+ charge will bond with the specie.
This will form:
MgO
This is notable for other group II elements.
2.In a titration, 25.00 cm3 of a solution of hydrochloric acid reacted with 18.40 cm3 of sodium hydroxide solution of concentration 0.15 mol/dm3.
The equation which represents the reaction is:
HCl + NaOH -----> NaCl + H2O
Calculate the concentration of hydrochloric acid in mol/dm3
Answer:
0.11mol/dm³
Explanation:
The reaction expression is given as:
HCl + NaOH → NaCl + H₂O
Volume of acid = 25cm³ = 0.025dm³
Volume of base = 18.4cm³ = 0.0184dm³
Concentration of base = 0.15mol/dm³
Solution:
The concentration of hydrochloric acid = ?
To solve this problem, let us first find the number of moles of the base;
Number of moles = concentration x volume
Number of moles = 0.15mol/dm³ x 0.0184dm³ = 0.00276mol
From the balanced reaction equation;
1 mole of NaOH will combine with 1 mole of HCl
Therefore, 0.00276mol of the base will combine with 0.00276mol of HCl
So;
Concentration of acid = [tex]\frac{number of moles }{volume}[/tex] = [tex]\frac{ 0.00276}{0.025}[/tex] = 0.11mol/dm³
