characteristic of compounds
Answer:
Characteristics of a compound
The properties of a compound are different from the properties of its constituents. Formation of a compound is generally accompanied by evolution of energy in the form of heat or light. A compound has a fixed melting point and boiling point. A compound is always homogeneous in nature.
Given a 0.5 M stock solution of aqueous NaCl, how much of the stock solution would you need to make a 50 mL sample of 0.25 M aqueous NaCl solution? How much water would you need to add to the NaCl solution?
Answer:
25 ml of stock
Explanation:
Molarity x Volume of Concentrated Stock = Molarity x Volume of Diluted Stock
=> Mc x Vc = Md x Vd => (0.5M)(x) = (0.25M)(50 ml)
=> x = Vc = (0.25M x 50 ml) / (0.50M) = 25 ml of stock

why are noble gases considered the most stable elements
Answer:
they have the maximum number of valence electrons their outer shell can hold.
Explanation:
An environmental chemist analyzed the effluent (the released waste material) from an industrial process known to produce the compounds carbon tetrachloride (CC14) and benzoic acid (HC7H5O2), a weak acid that has one acidic hydrogen atom per molecule. A sample of this effluent weighing 0.3518 g was shaken with water, and the resulting aqueous solution required 10.59 mL of 0.1546 M NaOH for neutralization. Calculate the mass percent of HC7H5O2 in the original sample.
The mass percent of benzoic acid in the sample is 55.5%.
The equation of the reaction is; HC7H5O2(aq) + NaOH(aq) ----> NaC7H5O2(aq) + H2O(l)
Number of moles of NaOH reacted = concentration × volume
Number of moles of NaOH reacted = 10.59/1000 L × 0.1546 M
Number of moles of NaOH reacted = 0.0016 moles of NaOH
Since the reaction is 1:1, 0.0016 moles of HC7H5O2 reacted also.
Hence, mass of HC7H5O2 = 0.0016 moles × 122 g/mol = 0.1952 g
Mass percent of HC7H5O2 in the original sample = 0.1952 g/ 0.3518 g × 100 = 55.5%

how toxic is uranium
Answer:
Inhaling large concentrations of uranium can cause lung cancer from the exposure to alpha particles. Uranium is also a toxic chemical, meaning that ingestion of uranium can cause kidney damage from its chemical properties much sooner than its radioactive properties would cause cancers of the bone or liver.

Answer:
Adaptation.
Explanation:
The survival characteristic adopted by Arctic foxes during different seasons is called adaptation.
The term adaptation is used to define any behavioral or physical characteristics adopted by animals to help them survive their environment. The survival characteristics in the animal can be categorized into three domains: body parts, body coverings, and behaviors. In Arctic foxes, we see body coverings survival characteristics.
