A doctor prescribes 125 mg of penicillan to be taken 4 times each day. The
concentration of the solution given to the patient is 250mg penicillan/5ml. How
many mL should the patient take in each dose?
1) 500 mL
2) 10.0 mL
3) 2.50mL
4) 50.0 mL
5) 2.0 mL
10 ml should the patient take in each dose
Further explanationGiven
125 mg of penicillan ⇒ 4 times/day
The concentration = 250 mg/5 ml
Required
The volume of the dose
Solution
The mass of penicillan/day :
= 125 mg x 4 times
= 500 mg
The volume/day :
= 500 mg : 250 mg/5 ml
= 10 ml

Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?
Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
Reaction stoichiometryIn first place, the balanced reaction is:
4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 molesThe molar mass of the compounds is:
NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 gramsMass of N₂ formedThe following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?
[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]
mass of N₂= 56.42 grams
Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

Hey can someone please help me with this
Answer:
This is not a redox reaction.
Explanation:
A redox reaction is a reaction that involves reduction and oxidation processes. The best way to identify a redox reaction. Changes in the oxidation number f the species indicates that it is a redox reaction.
Na+
Reactant side = +1, Product Side = +1; No change
Cl-
Reactant side = -1, Product Side = -1; No change
Ag+
Reactant side = +1, Product Side = +1; No change
N
Reactant side = +5, Product Side = +5; No change
O
Reactant side = -2, Product Side = -2; No change
There is no change in any of the oxidation numbers, Hence this is not a redox reaction.

A student increases the temperature of a 300 cm3 balloon from 40 °C to 110 °C.
What will the new volume of the balloon be? Round your answer to one decimal point.
(To convert, add 273.15)
Will Mark brainliest!!!
Answer:
367.1 cm³
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 300 cm³
Initial temperature (T₁) = 40 °C
Final temperature (T₂) = 110 °C
Final volume (V₂) =?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273.15
Initial temperature (T₁) = 40 °C
Initial temperature (T₁) = 40 °C + 273.15
Initial temperature (T₁) = 313.15 K
Final temperature (T₂) = 110 °C
Final temperature (T₂) = 110 °C + 273.15
Final temperature (T₂) = 383.15 K
Finally, we shall determine the final volume (i.e the new volume) of the balloon. This can be obtained by using the Charles' law equation as illustrated below:
Initial volume (V₁) = 300 cm³
Initial temperature (T₁) = 313.15 K
Final temperature (T₂) = 383.15 K
Final volume (V₂) =?
V₁/T₁ = V₂/T₂
300 / 313.15 = V₂ / 383.15
Cross multiply
313.15 × V₂ = 300 × 383.15
313.15 × V₂ = 114945
Divide both side by 313.15
V₂ = 114945 / 313.15
V₂ = 367.1 cm³
Therefore, the new volume of the balloon is 367.1 cm³

they use echos to communicate
Explanation: dolphins make echos in order to signal there partners, and others in there pod. or they can use it to signal for prey, or signal that they are in trouble.
Answer: A good example for this one is bats.
Explanation: While a couple of bats are known to emanate the beats through their nose, most bats will in general express them. The recurrence is estimated to be around 200 heartbeats each second, nonetheless, the time frame can fluctuate with the types of a bat. Credits: Adi Ciurea/Shutterstock A bat's squeaks are more rewarding than Ben's on the grounds that with higher recurrence comes higher-goal or more distinctive detail – they are equipped for evading deterrents no more extensive than a human hair! They use it to find and explore towards prey, for example, a hurrying bug. As the distinguished sound waves that structure the pictures are basically echoes, they should adjust to a standard — the recovered train of heartbeats should be sufficiently noisy to get back to the sender, yet short sufficient with the end goal that the reverberation of the sender returns before the following one withdraw.

For the following elements (Group 1A), Li, Na, K, Rb), which atom is larger overall?
Answer:
The smallest atom you have listed would be lithium (Li).
Explanation:
Lithium is the third smallest atom listed on the periodic table of the elements. It has an atomic number of three, meaning it has three protons in it's nucleus.
Atom size (Atomic radius) increases from UP to DOWN in the same COLUMN(group) of the periodic table. For example, in the first group, the Atomic radius trend from smallest to greatest is: H (smallest) -- Li -- Na -- K -- Rb -- Cs -- Fr (greatest).
Reason is, the increasing energy level (increases from n=1 to n=7) causes the shielding effect increase dramatically. And since the size of atom is mostly consist of electrons, more energy level is filled, the larger the atom will be.)
However, in the same ROW from left to right, the atomic size decreases as the number increases. For example, Li #3, is larger than Flourine (F) with an atomic number 9 because they are on the same ROW.

Highlight the examples of radiation in the passage
below.
A chemist working in the laboratory is
investigating the thermal energy of H2O in a
solid, liquid, and gas state. First, she places
ice in a pan on a burner and heats it. She
records the temperature at which the solid ice
melts. Next she takes the liquid water and
heats it in a microwave. The liquid begins to
bubble and evaporate into a gas. She records
the temperature at which the liquid water
turned into a gas.
Answer:
Heating of the liquid water in a microwave.
Explanation:
Radiation is a form of heat transfer process that does not require a material medium rather it travels through space or vacuum in the form of electromagnetic waves or radiation. Heat transfer by radiation occurs in the form of microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. Some common examples of heat transfer by radiation is the warming of the Earth by the Sun, the warmth one experiences while sitting by the campfire, or the heating up of foods in a microwave.
Black bodies or surfaces are good absorbers as well as emitters of radiation. On the other shiny or white surfaces are poor radiators of heat.
From the above discussion on radiation, it can be seen that when the chemist takes the liquid and heats it in a microwave, the heat absorbed by the liquid to change to gaseous state is transferred through radiation.
