Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga

Answers

Answer 1

Answer:

c. F

Explanation:

As you go top to bottom down a column of the periodic table, atomic radius increases.

As you go left to right across a period of the periodic table, atomic radius decreases.

Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Martha ran 420 m, and Cole ran 60 m less than Martha. The distance Kate ran is right in the middle of Martha and Cole's distances. How far did Kate run?

Answers

Answer:

390 m

Explanation:

Martha ran 420 m

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

The distance Kate ran is right in the middle of Martha and Cole's distances

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

Answer:

gas information The Monroe Doctrine was a United States policy that opposed European colonialism in the Americas. It argued that any intervention in the politics of the Americas by foreign powers was a potentially hostile act against the United States.[1] It began in 1823; however, the term "Monroe Doctrine" itself was not coined until 1850.[2]

U.S. President James Monroe

Secretary of State John Quincy Adams, author of the Monroe Doctrine

The Monroe Doctrine was issued on December 2, at a time when nearly all Latin American colonies of Spain and Portugal had achieved, or were at the point of gaining, independence from the Portuguese and Spanish Empires. It stated that further efforts by various European states to take control of any independent state in the Americas would be viewed as "the manifestation of an unfriendly disposition toward the United States."[3] At the same time, the doctrine noted that the U.S. would recognize and not interfere with existing European colonies nor meddle in the internal affairs of European countries.

President James Monroe first stated the doctrine during his seventh annual State of the Union Address to the Congress. The doctrine asserted that the New World and the Old World were to remain distinctly separate spheres of influence.[4] The separation intended to avoid situations that could make the New World a battleground for the Old World powers so that the U.S. could exert its influence undisturbed.[5] By the end of the 19th century, Monroe's declaration was seen as a defining moment in the foreign policy of the United States and one of its longest-standing tenets. The intent and impact of the doctrine persisted more than a century, with only small variations, and would be invoked by many U.S. statesmen and several U.S. presidents, including Ulysses S. Grant, Theodore Roosevelt, John F. Kennedy, and Ronald Reagan.

After 1898, the Monroe Doctrine was reinterpreted in terms of multilateralism and non-intervention by Latin American lawyers and intellectuals. In 1933, under President Franklin D. Roosevelt, the U.S. went along with this new reinterpretation, especially in terms of the Organization of American States.[6]

C)1,5, 2
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

Δx ≥4.54 * 10^-14 m

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.

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.

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!

2.7 x 10-2 grams of Pb(C2H302)4 are dissolved to make 3.5 mL of
solution. What is the molarity?
Your Answer

Answers

Answer:

The molarity is 0.0174 [tex]\frac{moles}{liter}[/tex]

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.

[tex]Molarity=\frac{number of moles of solute}{volume of solution}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case, being the molar mass of compound Pb(C₂H₃O₂)₄ equal to 443.38 g / mol, then the following rule of three can be applied: if 443.38 grams are contained in 1 mol, 2.7*10⁻² grams in how many moles they are present?

[tex]amount of moles=\frac{2.7*10^{-2} grams*1 mol}{443.38 grams}[/tex]

amount of moles= 6.09*10⁻⁵ moles

Being 1,000 mL= 1 L, then 3.5 mL= 3.5*10⁻³ L

So:

[tex]Molarity=\frac{6.09*10^{-5} moles}{3.5*10^{-3} L}[/tex]

Solving:

Molarity=0.0174 [tex]\frac{moles}{liter}[/tex]

The molarity is 0.0174 [tex]\frac{moles}{liter}[/tex]
