The major argument of opponents of the 1919Treaty of Versailles was that the treaty would
require the United States to
(1) become involved in future international
conflicts
(2) pay for war damages
(3) adopt a policy of military alliances
(4) keep troops permanently in Europe

Answers

The Treaty of Versailles would require the United States to become involved in future international conflicts.

  • The Treaty of Versailles was signed to end World War I in 1919.
  • The treaty also became a peace treaty presented by the Allied (France, Britain and the United States).
  • The opponents of the Treaty of Versailles, like, Germany oppose America involvement in Europe.
  • They believed that America, being disconnected geographically by the ocean, has no right to interfere.
  • When the United States had entered the war, the Germans protested.

Therefore we can conclude that Germans oppose America involvement in future international conflicts.

Thus option 1. is the correct answer.

You are giving an unknown element that dull in color. All you have to identify it is an electrical source and a meter that detects electrical charges. You would know it is a nonmetal if you turn on the electrical source and

Answers

Metals conduct electricity while nonmetals do not. Therefore if when you turn on the electrical source and the devise indicates a current, you know the substance is a metal. If you turn on the electrical source and the devise indicates no current, the substance is a nonmetal. I hope this helps. Let me know if anything is unclear.

Answers

Final answer:

Epithelial tissue can be multilayered and waterproof to protect from external threats, or single layered to allow for gas and nutrient exchange. Connective tissue supports and joins other tissues. Nervous tissue conveys information in the form of electrical transmission and is found in the brain and spinal cord. Muscle tissue consists of long, thin cylindrical cells that have specialized proteins for contraction.

Explanation:

The question is asking to match characteristics with their respective tissue types. There are four main types of tissues in the human body: epithelial tissue, connective tissue, nervous tissue, and muscle tissue.

Epithelial tissue is a protective tissue that can be multilayered and waterproof, or single layered to allow for exchange of gases and nutrients. It covers the surfaces of the body, lines the cavities and organs, and forms glands. Examples of epithelial tissue include the skin, the lining of the digestive tract, and the lining of blood vessels.

Connective tissue supports and joins other tissues. It provides structural support, connects and anchors organs, and stores energy. Examples of connective tissue include blood, bone, adipose tissue (fat), and fibrous tissue (tendons and ligaments).

Nervous tissue is responsible for transmitting electrical signals. It forms the brain, spinal cord, and nerves. Nervous tissue allows us to sense and respond to our environment, and it coordinates and controls body functions.

Muscle tissue consists of long, thin cylindrical cells that have specialized proteins for contraction. It allows for movement and generates force. There are three types of muscle tissue: skeletal muscle (attached to bones and responsible for voluntary movement), smooth muscle (found in the walls of organs and blood vessels, responsible for involuntary movement), and cardiac muscle (found in the heart and responsible for pumping blood).

Which unit is used to express the pressure of a gas?

Answers

According to the International System of Units, the unit of pressure is pascal (Pa). However, in calculating, we use atmosphere (atm), which is also a unit of pressure, more often.

Consider the following reaction: SO2Cl2(g)⇌SO2(g)+Cl2(g) A reaction mixture is made containing an initial [SO2Cl2] of 2.2×10−2M . At equilibrium, [Cl2]= 1.3×10−2M . Calculate the value of the equilibrium constant (Kc).

Answers

The value of equilibrium constant (Kc) will be 0.0188.

Equilibrium constant :

The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.

Given reaction:

SO₂Cl₂(g)⇌SO₂(g)+Cl₂(g)

To find:

Kc=?

The equation that represents kc for the given reaction will be:

k_c=([SO_2][Cl_2])/([SO_2Cl_2])

On substituting the initial concentration:

k_c=([SO_2][Cl_2])/([SO_2Cl_2])\n\nk_c=([1.3*10^(-2)][1.3*10^(-2)])/([2.2*10^(-2)-1.3*10^(-2)]) \n\nk_c=0.0188

Thus, the value of equilibrium constant (Kc)will be 0.0188.

brainly.com/question/12858312
The value of equilibrium constant is equal to the quotient of the products raised to its stoichiometric coefficient over the reaction's reactants raised to its respective stoichiometric coeff. The equation is Kc=[SO2][Cl2]/[SO2Cl2]= [1.3*10^-2][1.3*10^-2]/[2.2*10^-2-1.3*10^-2]=0.0188. The final answer is Kc=0.0188.

Within a particular compound, an atom gives up two electrons. This atom is A. part of a covalent compound.
B. positively charged.
C. negatively charged.
D. not part of an electrolyte.

Answers

Answer:

The correct answer is option B. positively charged.

Explanation:

Hello!

Let's solve this!

When an atom yields its electrons, it yields part of its negative charge. Therefore, it immediately transforms into a positively charged ion.

This positively charged ion is called cation.

We conclude that the correct answer is option B. positively charged.
Positively charged due to donating two electrons and becoming an ion.
