renal calculi contain crystallized calcium, magnesium, and uric acid. explain why patients with hyperparathyroidism would be at risk for developing renal calculi.
Patients with hyperparathyroidism would be at risk for developing renal calculi because of high calcium levels excreted by the kidney.
Hyperparathyroidism occurs when there is over secretion of parathyroid hormone by the parathyroid glands.
The parathyroid hormone is responsible for the following in the body:
Release of calcium by bones into the bloodstream. Absorption of calcium from food by the intestines, and Conservation of calcium by the kidneys.Renal calculi are strong masses of stones deposited in the kidneys or urinary bladder.
When there is excess calcium in the blood due to hyperparathyroidism, the kidneys would be over burdened with the excretion of excess calcium.
That extra calcium in the kidney & the urine leads to kidney stone development ( renal calculi).
Therefore, patients with hyperparathyroidism would be at risk for developing renal calculi because of high calcium levels excreted by the kidney.

What is the molar mass of ammonia (NH,)?
o 15 g/mol
o 17 g/mol
42 g/mol
43 g/mol
Answer:
17 g/Mol
Explanation:
To determine the molar mass of any compound, you have to add up the molar masses of every atom that make up the respective compound. In this case NH3 equals one nitrogen atom and three hydrogen atoms.
What does that mean? Ammonia's molar mass will be the sum of the molar mass of one nitrogen atom and 3 times the molar mass of a hydrogen atom.

You have 505 mL of a 0.160 M HCl solution and you want to dilute it to exactly 0.100 M. How much water should you add
This problem is providing information about the volume and concentration of HCl as 505 mL and 0.160 M respectively, and it is asking for the water that have to be added to prepare a 0.100-M solution.
In such a way, we work over the assumption of constant moles in dilution processes, so that we are able to write:
[tex]M_1V_1=M_2V_2[/tex]
Which relates de volume and concentration at the beginning and end of the experiment. This means we can solve for the resulting volume of the solution as a first calculation:
[tex]V_2=\frac{M_1V_1}{M_2}\\\\V_2=\frac{0.160M*505mL}{0.100M}=808mL[/tex]
Hence, the following amount of water must be added:
[tex]V_w=808mL-505mL=303mL[/tex]

Answer:
if by EXACTLY means 130.0000, then the answer is 3.3250
by EXACTLY means 1.299 <Kmass<1.301 then the answer is 3.33
EXPLANATION
which best represents the number of moles in exactly 130 grams of potassium metal?
the elemental mass of K is 39.098
so exactly 130 divided by 39.098 = 3.3250
if by EXACTLY means 130.0000, then the solution is 3.3250 by EXACTLY means 1.299 <Kmass<1.301 is 3.33
What is Potassium Metal?
Potassium metal responds rapidly with atmospheric oxygen to create flaky white potassium peroxide in exclusively moments of exposure.
It stood preferably isolated from potash, the ashes of plants, from which its appellation derives.
In the systematic table, potassium is one of the alkali metals, all of which have a single valence electron in the outermost electron shell,
That is easily drawn to produce an ion with a positive charge a cation, that connects with anions to form salts. Potassium in disposition materializes only in ionic salts.
When the elementary mass of K is 39.098
Therefore, exactly 130 divided by 39.098 is = 3.3250

Any of the Group 17 elements (the halogens) only need one additional electron to take on the electron configuration of the noble gas just to it's right. That would be argon (Ar) in this case.
For this reaction, the needs of both elements (to reach a stable Group 17 electron configuration) is matched: Just one electron is provided (Na) and taken (Cl) and that forms a single bond

Which image represents a homogeneous mixture?
Which image represents a heterogeneous mixture?
Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.
What are Homogenous and Heterogenous mixtures?A homogeneous mixture is defined as having a fairly uniform form and composition, so many homogeneous mixtures are referred to as solutions whereas heterogeneous mixtures are defined as separate substances or phases. The three states or states of matter are gas, liquid and solid.
Some examples of mixtures that include mixtures of sand and water, mixtures of sugar and salt, and mixtures of lime juice and water.
In homogenous solution, particles are distributed uniformly and have uniform composition while in heterogenous solution, particles are distributed non-uniformly and have non-uniform composition
Thus, Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

Heat is a form factor that changes the solid from light to light to gaseous mediums. The phases take place in a cyclic manner.
The solid to liquid changes take place due to the melting or fusion, solid to gas take lace through the sublimation, liquid to gas is by vaporization, and gas to liquid is condensation. Thus the heat is added and leads to the weakening of the electrical attraction within the molecules.Hence the correct option is C.

How did the scientists create atoms of element 115
Answer:
With ions of calcium in a cyclotron. This produced four atoms of moscovium. Moscovium is a synthetic element with the symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. In December 2015, it was recognized as one of four new elements by the Joint Working Party of international scientific bodies IUPAC and IUPAP. On 28 November 2016, it was officially named after the Moscow Oblast, in which the JINR is situated.[7][8][9]
Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds.[10] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as a heavier homologue of the pnictogen bismuth. Moscovium is calculated to have some properties similar to its lighter homologues, nitrogen, phosphorus, arsenic, antimony, and bismuth, and to be a post-transition metal, although it should also show several major differences from them. In particular, moscovium should also have significant similarities to thallium, as both have one rather loosely bound electron outside a quasi-closed shell. Over a hundred atoms of moscovium have been observed to date, all of which have been shown to have mass numbers from 286 to 290.
