Answer:

A. 1:1

Explanation:

Lithium 1s2 2s1

Chlorine 1s2 2s2 2p6 3s2 3p5

Lithium is a group 1 element. When it forms a compound, it loses it's one valence (outermost) electron.

Chlorine is a group 7 element. When it forms a compound, it gains one electron to achieve a stable electronic configuration.

Since Li loses one electron and Cl gains one electron. The formular of the compound formed would be;

LiCl

The correct option is;

A. 1:1

Answer:

15% adenine

Explanation:

Thymine and adenine are a nitrogenous base pair so they would equal the same.

Answer:

712 moles of Hg are produced

Explanation:

Based on the reaction:

2HgO → 2Hg + O₂

Where 2 moles of HgO reacts producing 2 moles of Hg and 1 mole of O₂

To solve this question we need to find the moles of Hg produced, then, using its molar mass:

Moles Hg:

3.55mol HgO * (2 mol Hg / 2 mol HgO) = 3.55 mol Hg

Grams -Molar mass Hg: 200.59g/mol-:

3.55mol Hg * (200.59g/mol) =

712 moles of Hg are produced

Answer:

What substance changed physically under all three condition? Copper Wire

What substance changed chemically under all three condition? Steel Wool

What evidence indicates a chemical reaction is occurring? New gases are produced; A phase change has occurred; A color change

Select the three answers that are examples of a chemical reaction. The mixing of an acid and base shows an increase in temperature; after baking bread there is a new odor or smell; when hair is bleached it changes to a lighter color

Which data supports this inference? Baking soda dissolving; A gas formed, creating bubbles

Which experiment best shows evidence of energy being released in a chemical reaction? Heat and light are given off when paper is burned

Which experiment likely resulted in the formation of a precipitate? Two solutions are mixed together and a yellow solid forms

The BEST evidence for a chemical reaction is the formation of a new substance.

Explanation:

2. When heat and light are being given off, energy is being released. Paper burning is a chemical reaction b/c when paper is burnt, it is a new substance and the act can't be undone.

3. When a yellow solid forms, that solid is the participate.

4. You will for sure have a chemical reaction if a new substance is created.

5. Copper wire changed physically b/c the copper wire can be returned to its original condition in all of these situations and no new substance was formed. Steel Wool changed chemically b/c it can't be returned to its original state under any condition and new substances were formed every time.

6. New substances formed indicate a chemical reaction. A color change also is an indication of a chemical reaction.

7. When a substance can't be turned into its original position or a new substance is produced, a chemical reaction occurred.

Answer:

the mass of 8.03 mole of NH3 is 136.51 g

Explanation:

The computation of the mass is shown below:

As we know that

Mass = number of moles × molar mass

= 8.03 mol  × 17 g/mol

= 136.51 g

Hence, the mass of 8.03 mole of NH3 is 136.51 g

We simply multiplied the number of moles with the molar mass so that the mass could come

Answer:

The melting of a glacier is an example of interaction among;

Hydrosphere, asthenosphere, atmosphere

Explanation:

The melting of a glacier is an example of the interactions among the Earth's cryosphere and hydrosphere

The cryosphere is described as the portions on Earth where water appears in solid (frozen) form such as glaciers, frozen grounds, snow covered land, sea ice, ice sheets, river ice, ice caps, etc.

The hydrosphere is all the forms water on a planet including, ice, liquid water and water vapor, therefore, the cryosphere is a part of the hydrosphere

The geosphere comprises the Earth's interior, including the asthenosphere, which is fluid and hot and therefore spread heat through both conduction and convection to the hydrosphere that raises the ocean temperatures and lead to glacier melting

The green house effect in the atmosphere results in global warming that raises the average temperature of the Earth which in turn raises the temperature of the oceans and the troposphere, resulting in melting of a glacier

Therefore, the melting of a glacier is an example of interaction among the hydrosphere, asthenosphere, and, atmosphere

Answer:

Q = 5805 Joules.

Explanation:

Given the following data;

Mass = 2250g

Specific heat capacity of silver = 0.129 J/g·°C

Initial temperature, T1 = 0.0°C

Final temperature, T2 = 200.0°C

To find the quantity of heat needed;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

dt = T2 - T1

dt = 200 - 0

dt = 200°C

Substituting the values into the equation, we have;

[tex] Q = 225*0.129*200[/tex]

Q = 5805 Joules.

Therefore, the amount of heat needed is 5805 Joules.

Given values:

                                                      [tex]= 200-0[/tex]

                                                      [tex]= 200^{\circ} C[/tex]

As we know the formula,

→ Heat capacity, [tex]Q = mcdt[/tex]

By substituting the values, we get

                                [tex]= 225\times 0.129\times 200[/tex]

                                [tex]= 5805 \ Joule s[/tex]

Thus the above answer is right.

Answer:

It is an covalent bond.

Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.

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]
