D)2,1,2
E)none of the above

PLEASE EXPLAIN WHY! I will mark the brainliest!

Answers

Answer:

C; 1, 5, 2

Explanation:

First, we do atom inventory:

Think of the arrow as a divider

On the left side, we have 4 phosphorus and 2 oxygens

On the right side, we have 2 phosphorus and 5 oxygens

Now we try to balance:

To make it easier, we want to try and make the 5 oxygens get to an even number so, we put a 2 in front of the P2O5 which makes it 2P2O5

Since we put a 2 in front of the P2O5, we have to multiply our phosphorus and oxygen on the right side by 2, which brings us to now have 4 phosphorus and 10 oxygens.

So now the oxygens are unbalanced.

To balance the oxygens, we put a 2 in front of the O2 located on the left side which makes us multiply our oxygen by 5, making it now 10.

Final result:

We end up having P4 + 5O2 = 2P2O5

An effective treatment for some cancerous tumors involves irradiation with "fast" neutrons. The neutrons from one treatment source have an average velocity of 3.5×107 m/s. If the velocities of individual neutrons are known to within 2.0% of this value, what is the uncertainty in the position of one of them?

Answers

Answer:

4.54 * 10^-14 m

Explanation:

From Heisenberg's uncertainty principle, we can write;

Δp.Δx ≥ h/4π

Given that;

Δp =Δmv

So;

Δmv.Δx ≥h/4π

Δmv =2/100(3.5×10^7 m/s * 1.66 * 10^-27)

Δmv =1.162 * 10^-21 Kgms-1

Δx ≥6.63 * 10^-34 /4 * 3.142 * 1.162 * 10^-21

What is air?

The term "air" is used to refer generally to the concoction of gases that composes the Earth's atmosphere. Nitrogen makes up the majority of this gas (78%), with oxygen, water vapor, argon, carbon dioxide, and trace gases also present.

There is no color or smell in pure air. Dust, pollen, and spores are common airborne contaminants; additional pollutants are alluded to as "air pollution." Since there isn't air in space, the so-called air on another planet, like Mars, would have different manufacturer.

6. A car is driving in a large circle at a constant speed of 20 miles per hour. Is the car accelerating? How do you know?​

Answers

The car is not accelerating, because the car is driving at a constant speed of 20 miles per hour.

You are watching the Indy 500 car race on television with your brother. He says, "Did you know that these cars race at a speed of over 200 mph? That velocity is amazing!" Having learned that speed and velocity are not the same, you decide to explain the difference to your brother.

Answers

Answer:

See explanation

Explanation:

All physical quantities are broadly classified into scalar quantities and vector quantities.

Scalar quantities have magnitude but do not have direction. Vector quantities have both magnitude and direction. Hence the main difference between a scalar quantity and a vector quantity is that a vector has direction while a scalar quantity does not.

Speed is a scalar quantity while velocity is a vector quantity. You have just specified a magnitude of 200 mph without mentioning its direction. This implies that you are referring to speed of the cars in the race and not velocity because velocity of the cars must indicate the direction!

which part of a star does the star’s energy come from?

Answers

Answer:

For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. At the end of a star's lifetime, its core becomes a stellar remnant : a white dwarf , a neutron star , or, if it is sufficiently massive, a black hole .

When developing a product such as cookware specific heat well as health cost and ease of use our important factors to consider one of the materials tested which is the best suited for cookware and why explain based on safety/health cost specific heat and ease of use

Answers

Answer:

In short, the thermal conductivity of a material is how readily that material absorbs and transmits (releases) energy. When the fire or heating element of a range comes in contact to a pan, the energy from the heat source is transmitted to the pan. This increases the internal kinetic energy of the pan (commonly called "heating up"). The heated material then transmits the energy to nearby materials that are at a lower average molecular kinetic energy level (at a lower temperature than the material). The higher the thermal conductivity of the material, the faster it will heat up and also, the faster the heated area will spread to unheated areas of the same piece of material.

For example, if we placed a large sheet of stainless steel (fairly low thermal conductivity as cooking materials go) on a burner and turned on the burner, the area directly under the burner would get hot while the rest of the sheet slowly heats up. The burner imparts heat quickly only to the region of steel directly over it. The rest of the pan heats up from the conduction of the heat from that spot. When the outer edges of the sheet have reached a hot temperature, the spot directly over the burner would be extremely hot. The figure below shows an example of the temperature of the sheet of steel over a gas burner. The hottest parts are shown in white, hot is red and cool is blue.

If a 67.3G rock is dissolved in 2.00L of acid, what is the molar concentration of gold in the acid solution

Answers

Answer:

[Au] = 0.171 M

Explanation:

For this question, we assume the rock is 100 % gold.

First of all, we determine the moles of gold

67.3 g . 1mol/ 196.97g = 0.342 moles

Molar concentration is defined as the moles of solute, contained in 1L of solution.

Our solution volume is 2L.

M = 0.342 mol / 2L = 0.171

Molar concentration, also called molarity of solution is the most typical unit of concentration.

Cole ran 60 m less than Martha = 420 m - 60 m = 360 m

Kate distance = (420 + 360) / 2 = 780 / 2 = 390 m

aqueous solution.
Na2Co3(aq)+FeCl,(aq) to
FeCo3(s) + NaCl(aq)
balanced:
Ionic Equation:
Net Ionic Equation:

Answers

Answer: The balanced molecular equation is:

[tex]Na_2CO_3(aq)+FeCl_2(aq)\rightarrow 2NaCl(aq)+FeCO_3(s)[/tex]

The ionic equation is:

[tex]2Na^+(aq)+CO_3^{2-}(aq)+Fe^{2+}(aq)+2Cl^-\rightarrow 2Na^+(aq)+2Cl^-(aq)+FeCO_3(s)[/tex]

The net ionic equation:

[tex]Fe^{2+}(aq)+CO_3^{2-}(aq)\rightarrow FeCO_3(s)[/tex]

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The balanced molecular equation is:

[tex]Na_2CO_3(aq)+FeCl_2(aq)\rightarrow 2NaCl(aq)+FeCO_3(s)[/tex]

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The ionic equation is:

[tex]2Na^+(aq)+CO_3^{2-}(aq)+Fe^{2+}(aq)+2Cl^-(aq)\rightarrow 2Na^+(aq)+2Cl^-(aq)+FeCO_3(s)[/tex]

The ions which are present on both the sides of the equation are sodium and chloride ions. and hence are not involved in net ionic equation.

The net ionic equation:

[tex]Fe^{2+}(aq)+CO_3^{2-}(aq)\rightarrow FeCO_3(s)[/tex]
