Answer:

16 g.

Explanation:

The formula for carbon monoxide is CO.

So there is one atom of oxygen in the formula, therefore there is one mole of oxygen gas ( one mole occupies 22,4 L at STP)

One mole of oxygen atoms =  atomic mass of oxygen in grams = 16 grams.

[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.

Answer:

Temperature is the average kinetic energy of the molecules. Absolute zero is the temperature where molecular motion stops and is the lowest possible temperature. ... The relationship between Celsius and Kelvin temperature scales is given by K = °C + 273.15.5

Answer:

Six valence electrons!!

Explanation:

Hope this helps!!

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

Answer:

3.40x10¹⁰ grams

Explanation:

First we convert 5.25x10³² atoms to moles, using Avogadro's number:

5.25x10³² atoms ÷ 6.023x10²³ atoms/mol = 88.72x10⁸ mol

Then we convert K moles to grams, using its molar mass:

88.72x10⁸ mol * 39 g/mol = 3.40x10¹⁰ g

So 5.25x10³² atoms of K would weigh 3.40x10¹⁰ grams.

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]

Explanation:

Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.

There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.

Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

Explanation:

They travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space. Hence, option C is correct.

An electromagnetic wave (radiation) can be defined as a type of wave that does not require any medium for its propagation. Also, light energy is a good example of an electromagnetic wave (radiation).

Electromagnetic waves are used in science as a propagating medium used in all communication processes device to transmit data from the device of a sender to the device of the receiver.

Answer:gas formation

Explanation:

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]
