Answer:
Hyperkalemia
Explanation:
The condition of acidosis can also cause Hyperkalemia because the higher H concentration diffuses to the ICF, pushing K towards the ECF.

How many molecules are present in this formula? 3H2 (SO)4
Molecules are formed when two or more atoms chemically bond together. In 3H₂(SO)₄, three molecules are present.
What are molecules?Molecules are the smallest unit present in any compound and are formed by a group of atoms. A number denoted in front of the chemical species is the coefficient that represents the number of molecules.
The coefficient present in front of the reactant or the product in a chemical reaction gives the number of the molecules present in a compound. As three is denoted in front of the sulphuric acid, hence will be the number of the molecules.
Therefore, there are three molecules present in sulphuric acid.

(fence post model)
Answer:
hola espero que mi respuesta ayude
Explanation:
The concentration of hydroxide ion (-OH) in 1.37 x10^-5 m solution of Ba(OH)2 is calculated as follows
write the equation for dissociation of Ba(OH)2
Ba(OH)2 = Ba^2+(aq) + 2OH^-(aq)
by use of mole ratio between Ba(OH)2 to OH^- which is 1:2 the concentration of OH^- = 2x ( 1.37 x10^-5) = 2.74 x10^-5 M

a. spring.
c. aquifer.
b. well.
d. travertine.
A natural flow of ground water that has reached surface level is call a spring.
Water moves underground downward and sideways, in great quantities, due to gravity and pressure.
A spring is the result of an aquifer being filled to the point that the water overflows onto the land surface. They come in different sizes, from intermittent seeps, which flow only after much rain, to huge pools flowing hundreds of millions of gallons daily.

The ribosomes of plant cells are sites for the synthesis of
(a) ATP (b) nucleic acids (c) sugars (d) proteins
Answer:
Proteins
Explanation:
Their Function Formation Encoded in mRNA into polypeptide chains of amino acids that produces protein
The ribosome of plant cells are sites for the synthesis of proteins. The correct option is (d).
What are ribosomes?Ribosomes are organelles that take part in the synthesis of proteins. The prokaryotic cell's ribosomes are smaller than the eukaryotic cell's ribosomes.
Currently, ribosomal RNA is a component of the cell's ribosome or protein-building machinery. The process of making proteins, or translation, is carried out by ribosomes.
The ribosome, which translates the genetic code generated in mRNA into an amino acid sequence, is universally responsible for protein synthesis. The two ribosomal subunits, small and big, come together to form the full ribosome, which is used to produce proteins.
Therefore, the correct option is (d) proteins.

Answer:
We have the atoms, and we have the molar mass of Vanadium (listed in the periodic table) which should be 50.94g/mol.
The first step is to convert the 4.18 x 10^23 atoms into moles by dividing the atoms by Avogadro's number (6.02 x 10^23)
(4.18 x 10^23)/(6.02 x 10^23) = 0.694 moles
Now we know that moles is equal to the mass divided by the molar mass. So now that we have the moles and the molar mass of Vanadium, we can rearrange the equation to find mass. Once you have rearranged it, you have to multiply the moles by the molar mass.
So 0.694 moles x 50.94g/mol = 35.35g of V

Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth
Newton's Second law of motion states that "the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object."

Explanation:
noble gases are used in many situations where a safe and constant environment must be maintained. for example, helium is used to provide a protective atmosphere for making fiber optics and semiconductors. argon is used to fill incandescent and flourescent light bulbs to prevent oxygen from corroding the hot filament. why are noble gases used in these situations?
Answer:
Because they do not naturally react with other elements
Explanation:
Since noble gases do have a fulfilled valence shell, they do not react with other elements because they're already stable by the themselves.
Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.

Based on the data, should the scientist accept or reject his hypothesis?
Answer:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Butane (C4 H10(g), Delta. Hf = â€"125. 6 kJ/mol) reacts with oxygen to produce carbon dioxide (CO2 , Delta. Hf = â€"393. 5 kJ/mol ) and water (H2 O, Delta. Hf = â€"241. 82 kJ/mol) according to the equation below. 2 upper C subscript 4 upper H subscript 10 (g) plus 13 upper o subscript 2 (g) right arrow 8 upper C upper O subscript 2 (g 0 plus 10 upper H subscript 2 upper O (g). What is the enthalpy of combustion (per mole) of C4H10 (g)? Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants. â€"2,657. 5 kJ/mol â€"5315. 0 kJ/mol â€"509. 7 kJ/mol â€"254. 8 kJ/mol.
The enthalpy of this reaction is -5315 KJ/mol.
The equation of the reaction is;
2C4H10(g) + 13O2(g) -----> 8CO2 (g) + 10H2O(g)
We know that the enthalpy of reaction can be obtained from the enthalpy of formation of the reactants and products as follows;
ΔHrxn = ΔHf(products) - ΔHf(reactants)
We have the following information from the question;
ΔHf C4H10 = - 125. 6 kJ/mol
ΔHf CO2 = - 393. 5 kJ/mol
ΔHf H2O = - 241. 82 kJ/mol
ΔHf O2 = 0 KJ/mol
Hence;
[(8 × (- 393. 5 )) + (10 × (- 241. 82))] - [2( - 125. 6))]
= -5315 KJ/mol
