Answer:
0.0252mol/L
Explanation:
The following data were obtained obtained from the question:
Volume of solution = 284mL = 284/1000 = 0.284L
Mole of CuSO4 = 7.157 × 10^-3 mol
Molarity =?
Molarity = mole/Volume
Molarity = 7.157x10^-3 /0.284
Molarity = 0.0252mol/L
The concentration of the solution is 0.0252mol/L
Answer:
The question lacks options, the options are:
A) Energy is transferred to consumers, which convert it to nitrogen and use it to make amino acid
B) Energy from producers is converted into oxygen and transformed to consumers.
C) Energy from the sun is stored by green plants and transferred to consumers.
D) Energy is transferred to consumers, which use it to produce food.
The answer is C
Explanation:
Organisms obtain energy in an ecosystem by feeding on one another in a chain called FOOD CHAIN. Energy is transferred when one organism feeds on another. A food chain always begins with a PRODUCER, which is an autotrophic organism capable of producing its own food via light energy from the sun.
In a terrestrial ecosystem, the energy a plant captures via Its Chlorophyll is used to produce food during photosynthesis. This energy is stored in the plants and transferred when a set of organisms called PRIMARY CONSUMER feeds on the plant. The transfer continues in that order till decomposers.
An electron has a negative charge. When an atom loses an electron, it becomes a positive ion.
When an atom of lithium loses an electron and becomes an ion, it has one less electron shell, so its radius is smaller than the radius of the atom.
The answer is 3.
Non-metal atoms gain an electron, or electrons, from another atom to become >negatively charged ions.
Charles law gives the relationship between volume and temperature of gas.
It states that at constant pressure volume is directly proportional to temperature
Therefore
V/ T = k
Where V - volume T - temperature in kelvin and k - constant
V1/T1 = V2/T2
Parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
Substituting the values in the equation
267 L/ 480 K = V / 750 K
V = 417 L
Final volume is 417 L
