Answer:group 1A(1)
Explanation:
Arctic foxes grow new fur with different seasons. They grow brown fur in the summer and white fur in the winter. These changes are examples of which survival characteristic?
adaptation
hibernation
metamorphosis
migration
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.
Therefore, option A is correct.

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
Which statement describes a physical property of copper?
Answer:
Copper is typically a solid and has a coppery, bronzy color. It is a metal and has a relatively high melting point. It has a strong luster and can conduct electricity.
Answer:
RESHAPE BY A FORCE.
Explanation:
1. It can be reshaped by a force. Physical property can be observed and measured without any changes in molecular composition.
2. A physical property is one that can be change without altering the identity of the substance. These set of properties is not concentration dependent they are use to describe matter. Example are: density, solubility, melting point and color and odor. For this case the second option seems to fit the description it can be reshape by force.
In terms of percentages, what are the 3 biggest uses of natural gases?

Q1. Consider respiration, one of the most common chemical reactions on earth occur according
to the reaction:
C6H1206 +602 = 6CO2 + 6H2O + energy
What mass of CO2 forms in the reaction of 25g of glucose with 40g of oxygen?
Answer: First we need to know how many moles of each reactant there are.
C6H12O6 : 25g/180.06g/mol=0.1388mol
O2: 40g/32g/mol=1.25mol
The equation tells us we need 6 moles of O2 for every 1 mole of Glucose.
6 x 0.1388 = 0.8328
So, we have more O2 then needed – it is in excess.
Glucose is the limiting reagent – we use this for the calculation.
The equation tells us we make 6 moles of CO2 for every 1 mole of Glucose
So, we make 0,8328 moles of Carbon Dioxide
Explanation:
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.

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.

A compound has the combined properties of the elements from which it is made. Atoms show the macro properties of an element.
Hybridization
of Bromine in BrF5
Answer:
the hybridization of bromine in BrF5 is SP³d².
Explanation:
Because its forms five single bond &have one lone pair that consider as sigma. So total sigma bond is 6. Hence hybridisation is SP³d².
