Answer:
C) nonmetal
Explanation:
Given;
The sample is in liquid state and do not conduct electricity.
We have given four types of classification.So for first,
A) Ionic
Ionic compounds are found in solid state at room temperature and it conducts electricity when dissolved in water. Hence the sample could not be ionic.
B)Metal
Metals are found in solid state at room temperature except mercury and it conducts electricity very well. Mercury also conducts electricity.So the sample is not a metal.
C)Nonmetal
Non metals are found in solid state except bromine which is in liquid state at room temperature and it does not conducts electricity.
Here the property of nonmetal matches with the sample, so the sample is a nonmetal and it could be Bromine.
D)Salt
Salt is an ionic compound found in solid state at room temperature and it conducts electricity when dissolved in water. Hence the sample could not be salt.
A molecule with a triple covalent bond is N2
Na would be the best conductor of electricity

Answer:
For mole conversion always remember 1 mole of compound = molar mass of compound.
Ex. 2 moles H20 to grams
2mol H2O x 18 g / 1mol H20
For molecules use Avogadro's number like moles multiplied to 6.022x10²³ answer will be in molecules.
Explanation:
The waste from the human body is removed in the form of urea and nitrogenous wastes. The urine comprises 95 % water and 5% waste ions formed via glomerular filtration, reabsorption, and secretion.
<h3>How does the urinary system work?</h3>
Waste of the human body can be described as excreted from the human body, especially in the form of urine. Our kidneys play important in the process of excretion. Components of normal human urine include 95 % water and 5 percent solid wastes.
Urine is formed in the nephron, which is the structural and functional unit of the kidney. Urine formation is carried out in three phases Glomerular filtration, Reabsorption, and Secretion.
Glomerular filtration takes place in the glomerulus where blood is filtered. Around 99 percent of the filtrate is reabsorbed by the renal tubules known as reabsorption. The secreted ions are combined with the filtrate and form urine.
