How many penicillin molecules would you have if you had a total of 36 hydrogen atoms? What would be the total atomic mass?
Answers
Answer:
Explanation:
Molecular formula of penicillin = C₁₆ H₁₈ N₂ O₄S
No of hygrogen atoms = 36
No of molecules = 36 / 18 = 2
molecular weight = 334 amu
molecular weight of 2 molecules = 334 x 2 = 668 amu.

if its 5X 10^3 mm=5m and if its 5X 10^-3 mm=5X 10^-6m
Explanation:
we know,
1m= 1000mm
as given 5X 10^3 mm we have to convert to meter
now 5X 10^3 mm= 5X 10^3/1000=5m
but if its 5X 10^-3 mm= 5X 10^-3/1000= 5X 10^-6m

MACROMOLECULES:
Macromolecules are large or complex molecules made up of monomers. The macromolecules in nature are as follows: proteins, carbohydrates, lipids and nucleic acids. Each macromolecule performs specific functions in the body and hence, are very important. Carbohydrates and lipids are used as energy storage, however, lipids store energy in the body for a long term than carbohydrates. Carbohydrates store energy for a short term because they are readily used by the body.Therefore, both macromolecules are used for energy storage, but only carbohydrates are used for short-term energy storage.

What is the density of 19 milliliters of a liquid substance with a mass of 6.05 grams?
Answers
Answer:
The answer is
0.32 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} [/tex]From the question
mass = 6.05 g
volume = 19 mL
The density of the substance is
[tex]density = \frac{6.05}{19} \\ = 0.3184210526...[/tex]
We have the final answer as
0.32 g/mLHope this helps you

Which phrase best describes igneous rocks?
form when lava and magma cool
accumulate sediments following erosion
require heat and pressure to be formed
consist of many sediment layers
Answers
Answer:form when magma and lava cool :/
Explanation:hope this helps, and I’m this because ingenious rocks are made/ formed from magma and lava.
The phrase which best describes igneous rocks is option A, .i.e., it forms when lava and magma cool.
What is igneous rock?Igneous rocks are formed by the melting of earth's crust into magma, . The two types of this rocks are, Extrusive and intrusive igneous rocks . The slow cooling of magma beneath the surface results in intrusive igneous rock.
Magma in the crystal is in molten liquid state which heat by convection and flows out. This creates slight movement in plates and the hot mantle the cools down to form igneous crystals.
Extrusive igneous rock is created when lava above the surface cools quickly. The magma hardens more quickly after being brought to the surface via cracks or volcanic explosions. As a result, these rocks are crystalline, smooth, and fine-grained.
Thus regarding the formation of igneous rocks, option A is correct.

What happens when a Bose-Einstein condensate forms?
A. A large atom is split into many smaller atoms temporarily.
B. The atoms of the solid condense into one large superatom.
C. It causes all matter touching it to condense into a liquid.
D. The electrons separate from the nuclei forming a mass of unbound positive and negative charges.
Answers
Answer:
the answer would be B
Explanation:
The atoms of the solid condense into one large superatom. Hence, option B is correct.
What are atoms?An atom contains a central nucleus surrounded by one or more electrons.
Bose-Einstein condensation occurs at a temperature very close to absolute zero i.e 273.15 degrees centigrade. Under such conditions, a large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena become apparent macroscopically. A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra-low temperature.
Hence, option B is correct.

O Water exhibits strong adhesion and cohesion, which allows capillary action to occur.
Water has low surface tension, which prevents capillary action from occurring.
Water has high surface tension, which prevents capillary action from occurring.
Answers
Answer:
B water exhibits weak adhesion and cohesion which allows capillary action to occur.
Explanation:
took the test
Water exhibits strong adhesion and cohesion, which allows capillary action to occur.
What property of water allows it to move through a plant?The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be 'pulled' up through the plant as water molecules are evaporating at the surfaces of leaf cells. This process has been termed the Cohesion Theory of Sap Ascent in plants.
What are adhesion and cohesion?Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself and adhesion means that water likes to stick to other things.

What must occur in order for a chemical reaction to be specifically classified as endothermic instead of
exothermic?
Atoms are rearranged.
Chemical bonds are formed.
Energy is released in the form of heat.
Energy is absorbed in the form of heat.
Answers
Answer:
A
Explanation:
What must happen in order for a chemical reaction to be specifically classified as endothermic instead of exothermic is that energy is absorbed in the form of heat.
Chemical reactions can be exothermic or endothermic depending on whether it gives off or absorb energy (in the form of heat).
When energy is given off by a reaction, the temperature of the reaction vessel becomes warmer than the initial temperature before the reaction. Such a reaction is said to be exothermic.
For endothermic reactions, heat energy is absorbed from the surrounding. Thus, the reaction vessel appears colder when compared to the initial temperature before the reaction.

Answers
Complete question is;
Molding a shape from soft, malleable material (clay or plaster) or constructing a shape from harder material (such as metal or paper) is called what?
Molding is what a child does with Play-Doh or origami
Answer:
Modeling
Explanation:
In chemistry, we have a branch called modeling chemistry. In modeling, we organize together a series of models instead of a collection of topics. In this approach, we will begin with a phenomena that can be readily observed and are gradually develop the simplest model of matter that helps us make sense of our observations.
Now in the question, we are Molding a shape from soft, malleable materials like clay/plaster or constructing from harder materials like metal/paper. This means that we are organizing a series of models from either soft & malleable or harder materials to produce a simple model shape.
Thus, this is simply modeling.
