<u>Out of all given option, the following statements are true about a system:</u>

  • A system is a group of objects analyzed as one unit.
  • Energy that moves across system boundaries is conserved

Answer: Option A and B

<u>Explanation:</u>

A system is "a complicated item whose parts or segments are identified with probably a portion of different segments", it very well may be material or calculated. All systems have piece, structure, and condition, yet just material systems have instruments (or forms), and just some material systems have shape.

As per systems, all articles are systems or segments of another system. For instance, a nuclear core is a physical material system made out of protons and neutrons related by solid atomic association; a cell is a natural material system made out of related organelles by non-covalent synthetic securities and metabolic pathways; and a logical hypothesis is a consistent reasonable system made out of theories, definitions, and hypotheses related by relationship and conclusion.

What volume of solution gives the desired moles?
motikmotik

Answer:

1. 0.073L

2. 0.028L

3. 0.014L

Explanation:

The volume for the different solutions are obtained as shown below:

1. Mole = 0.53mol

Molarity = 7.25M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.53/7.25

Volume = 0.073L

2. 0.035mol from a 1.25M

Mole = 0. 035mol

Molarity = 1.25M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.035/1.25

Volume = 0.028L

3. Mole = 0.0013mol

Molarity = 0.090M

Volume =?

Molarity = mole /Volume

Volume = mole /Molarity

Volume = 0.0013/0.090

Volume = 0.014L

What is the potential energy of 4kg object sitting on a 3m ledge?
bagirrra123 [75]
Potential energy (Pe) = m*g*h

m = 4 kg
g = 10 m/s²
h = 3 m

And now:

Pe = 4*10*3

Pe = 120 Joules ou J

elixir [45]
Well you didn't list the following. So
Primary elements would be the sequence of amino acids
Secondary would be interactions between nearby residues, such as beta sheets and alpha helices
Tertiary would be the overall 3-D structure, including disulfide bonds
Quaternary refers to interactions among polypeptide chains
