THANK YOU.

Answer:

When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.

Answer:

The sun

Explanation:

Because plants use sunlight to conduct photosynthesis which is the process the need to create energy

Answer:

The answer is A

Explanation:

I dont see any claim

Answer:

You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Whenever the plant needs energy, it can chomp a little glucose off of the starch.

without energy it wont get energy/food so it will eventually die

Answer:

A. H2O

Explanation:

Let us first define the three types of bonds:

1. Nonpolar Covalent: electronegativity difference < 0.4

2. Polar Covalent: electronegativity difference between 0.4 and 1.8

3. Ionic: electronegativity difference > 1.8

This will help us eliminate choices C and D:

-NaCl has a electronegativity difference of 3.0 - 0.9 = 2.1 (ionic bond)

-Cl2 has a electronegativity difference of 3.0 - 3.0 = 0 (nonpolar covalent bond)

However, we still have two more options, A and B, but they are not diatomic for us to use the electronegativity differences with.

We must now consult their geometries. Because CO2 has a linear geometry (O=C=O), the two sides will cancel each other out, resulting in a nonpolar covalent bond. At this point, by process of elimination, we can already determine the answer to be A. H2O. We can verify this by looking at the geometry of H2O, which is bent (H-O-H; imagine the O is above the H's, I cannot draw it in this response). H2O's bent geometry classifies it as polar covalent; the electrons are slightly more attracted towards the O, the more electronegative element. Side note: this makes the O slightly more negative in charge, whilst the H's are slightly more positive in charge.

P.S. I apologize for not being able to draw and demonstrate that last paragraph, but I hope you get a general idea. You can search up the "H2O geometry" and "CO2 geometry" to get a better idea! :)

H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct

A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond.

Consider the hydrogen chloride (HCl) molecule. Each atom in HCl requires one more electron to form an inert gas electron configuration.

Water (H₂O), like hydrogen Chloride (HCl), is a polar covalent molecule. When we look at a diagram of water , we can see that the two hydrogen atoms are not evenly distributed around the oxygen atom

Water (H₂O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule.Thus, This is an example of polar covalent chemical bonding.

Therefore, H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct

Carbon Tetrahydride reacts with Oxygen gas to form Carbon Dioxide gas and Dihydrogen Monoxide gas.

Explanation:

10 ml should the patient take in each dose

Given

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

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

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.

Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

In 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:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The 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.

Answer:

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.

Answer:

Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.

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.
