Answer:

should be made illeagl everywhere

Explanation:

i took the test

Abraham Lincoln believed that American democracy meant equal rights and equality of opportunity. According to him, slavery is wrong both morally and politically. He said that slavery should be made illegal everywhere. The correct option is B.

The 13th Amendment to the U.S constitution ratified in 1865 in the aftermath of the civil war, abolished slavery in the united states. The 13th Amendment states that ''Neither slavery nor involuntary servitude, except as a punishment for crime shall exist within the united states.

The term slavery indicates the ownership of a person as property, especially in regards to their labor. A slave is a person who is owned by another person or is forced to work against their own will.

Lincoln's position on slavery in the united states is one of the most discussed aspects of his life. Lincoln frequently expressed his moral opposition to slavery in public and private.

Thus the correct option is B.

Explanation:

The troposphere forms the lowest level of the Earth's atmosphere, extending down to the surface of the Earth. This layer also features the heaviest weight of all Earth atmosphere layers, comprising approximately 75 percent of the total atmospheric weight. The troposphere varies in thickness and height around the world.

Explanation: Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.)

Answer:

A chemical reaction occurs when reactants are converted into products. A chemical equation is a representation of a chemical reaction using chemical symbols. The chemical equation also indicates the physical state of the reactants and products. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

Explanation: because UwU

A chemical equation is an expression that gives the identities and quantities of a chemical reaction. A chemical equation shows the reactants on the left side and the products on the right which are separated by an arrow.

A chemical equation is the representation of a chemical reaction in terms of symbols of the substances. A chemical equation consists of reactants participating in the reaction, formed products, and an arrow showing the direction of the chemical reaction.

The equation in which the number of atoms of substances is equal on either side of the equation is called a balanced chemical equation.

The law of conservation of mass follows by a balancing of a chemical equation. According to this law, in a chemical reaction, the mass can neither be created nor destroyed.

By obeying this law, the total mass of the elements present on the reactant side should be equal to the total mass of elements present on the product side in a balanced chemical equation.

Answer:

A new substance was forming

Explanation:

Two types of changes are undergone by substances involved in a reaction. They are physical changes and chemical changes. Physical changes are those changes that does not involve the synthesis of a new product. On the other hand, CHEMICAL CHANGES alters the chemical composition of the substances involved, and hence, new substances are formed.

Chemical changes are usually characterized by change of temperature, color change, evolution of a gas etc. According to this question, Mia mixed two substances in a test tube and noticed that the test tube became warm. She also noticed gas coming from the test tube. Based on Mia's observations, a CHEMICAL CHANGE, LEADING TO THE FORMATION OF NEW SUBSTANCE, HAS OCCURRED.

Explanation: There is more force pulling on the object

Answer:

119.0023 grams

Explanation:

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles KBr, or 119.0023 grams.

The mass of one mole of KBr is 118 grams. Hence, the mass of 9.3 moles of KBr is 1097.4  grams.

Potassium bromide is an ionic compound formed from combination of potassium and bromine atom involving the loss of electron from the potassium metal to the bromine atom.

The atomic mass of potassium (K) = 39 g/mol

atomic mass of Br = 79 g/mol

Hence, the molar mass of KBr = 79 + 39 = 118 g/mol

Therefore , the mass of one mole of KBr is 118.

The mass in grams of 9.3 moles of potassium bromide is thus, 9.3 times the mass of one mole of KBr. Thus,

mass of 9.3 moles = 9.3 × 118 = 1097.4 g.

Therefore, the mass in grams of 9.3 moles of KBr is 1097.4 g.

Answer:

1.78 atm

Explanation:

From the question given above, the following data were obtained:

Mass of Cl = 355 g

Molecular weight of Cl = 70.9 g/mol

Volume (V) = 70.0 L

Temperature (T) = 30 °C

Pressure (P) =?

Next, we shall determine the number of mole in 355 g of chlorine (Cl). This can be obtained as follow:

Mass of Cl = 355 g

Molecular weight of Cl = 70.9 g/mol

Mole of Cl =.?

Mole = mass /molecular weight

Mole of Cl = 355 /70.9

Mole of Cl = 5 moles

Next, we shall convert 30 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Temperature (T) = 30 °C

Temperature (T) = 30 °C + 273 = 303 K

Finally, we shall determine the pressure of the gas as illustrated below:

Volume (V) = 70.0 L

Number of mole (n) = 5 moles

Temperature (T) = 303 K

Gas constant (R) = 0.0821 atm.L/Kmol

Pressure (P) =?

PV = nRT

P × 70 = 5 × 0.0821 × 303

P × 70 = 124.3815

Divide both side by 70

P = 124.3815 / 70

P = 1.78 atm

Therefore, the pressure of the gas is 1.78 atm

The pressure of the gas in atmospheres if it's temperature is 30.0 degrees celcius is 1.77 atm.

Pressure of the given gas will be calculated by using the ideal gas equation as:

PV = nRT, where

P = pressure of chlorine gas = ?

V = volume of chlorine gas = 70 L

R = universal gas constant = 0.082 L.atm / K.mol

T = temperature chlorine = 30 degree celsius = 303 K

n is the moles of gas which can be calculated as:

n = W/M, where

W = given mass of chlorine gas = 355g

M = molar mass of chlorine gas = 70.9g/mol

n = 355/70.9 = 5 moles

On putting all these values on the above equation and calculate for P, we get

P = (5)(0.082)(303) / 70

P = 1.77 atm

Hence required pressure is 1.77 atm.

Answer:

See the answer below

Explanation:

Beryllium forms an ion with 2 electrons in its outermost shell. Hence the charge on the element is 2+, that is,  Be2+. In order for Be to form a stable bond with another element, such an element must have a deficit of electrons  in its outermost shell. Beryllium will have to donate its 2 electrons to this element for its self-stability.

Answer:

The correct answer is 10 core electrons and one valence electron.

Explanation:

The electrons in an atom, which are not valence and do not take part in chemical bonding are known as core electrons. The core electrons and the nucleus of an atom produces the atomic core. These core electrons are held tightly with the nucleus. On the other hand, the outer shell electrons, which are associated with an atom and take part in the generation of a chemical bond is the outer shell is open are known as valence electrons.

In the given question, the atomic number of an element is 11, thus, the electronic configuration will be,

1S² 2S² 2P⁶ 3S¹

Hence, there is only one valence electron and 10 core electrons.
