Answer:

192g

Explanation:

so for this find out there moles of CH4 by moles=mass/mr

48/16=3 then use molar ratio 1:2 so times it by 2 which is 6 moles. then uses mass =moles*mr so 6*32=192g is the answer hope this helps to understand.

Veneno.

Explicación:

El veneno es la sustancia que puede causar la muerte porque el veneno destruye las células que entran en contacto con el veneno. Si el veneno causa menos daño por lo que no ocurre la muerte del paciente mientras que por otro lado, si el veneno entra en contacto con los órganos vitales y causa más destrucción, el paciente eventualmente morirá, por lo que podemos decir que las sustancias tóxicas y venenosas causan daño y muerte. de la gente.

meaning:An acid is a chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts. Some acids burn or dissolve other substances that they come into contact with.

Answer:

Bonding property

Explanation:

Distillation deals with boiling solutions. Therefore the boiling point has a major part to play. Boiling point of a substance deals with the type of bonds present. For example water has hydrogen bonding which is a weak intermolecular force therefore the boiling point of water isn't that high. If we were to focus on an ionic compounds the boiling point would be higher because ionic compounds have ionic bonding which are stronger bonds which therefore requires more energy to break those bonds therefore a higher boiling point.

In this case for the ethanol to distill the property it's focusses on is the bonds. The strength of the bonds really.

Explanation:

Answer:

Solution given:

H20=1+1+16=18grams

we have

1 mole of water =18grams

now

150grams of water=1/18*150=25/3 =8.33mole.

150 grams of water =8.33mole.

Note:

mole =given mass/actual mass of molecule/atom

1 mole of water is 18 grams.

Then,

150 grams of water,

→ 1/18 × 150

→ 25/3

→ 8.33333 . . .

Hence, 150 grams of water is 8.3 moles.

Answer:

Ionic bond and covalent bond

Explanation:

The two main types of chemical bonding are ionic bond and covalent bond.

In an ionic bond, there is a transfer of electrons from one atom to another. Usually from a metal to a nonmetal leading to the existence of an ion pair. Ionic compounds are soluble in water and have high melting and boiling points due to the strong electrostatic interaction between ions in the compound.

A covalent bond involves sharing of electrons between atoms. In an ordinary covalent bond, the shared electrons are furnished by the two bonding atoms while in a dative covalent bond, the two bonding electrons are furnished by only one of the bonding species.

C. The final substance in beaker A is a pure substance while in Beaker B is a mixture

Explanation:

A pure substance is a substance that contains a constant and definite proportion of a single substance. Elements and compounds are the two known pure substances while mixtures are substances of different compositions mixed together.

In this question, two beakers; A and B are said to contain different substances. Beaker A contains elemental sulfur (S) that forms a yellow powder while beaker B contains sand and water. From the explanation above, the final substance in beaker A is a pure substance (element) while in beaker B is a mixture of sand and water.

The given molecule is an aldehyde with the formula HCHO. It is the simplest and primary aldehyde . Hence, option c is correct.

Aldehydes are a class of organic compounds that contain a carbonyl group (a carbon double-bonded to an oxygen) at the end of a carbon chain. The general formula for an aldehyde is RCHO, where R is a substituent or side chain attached to the carbonyl group.

Aldehydes are often characterized by their distinctive odor, which can be described as pungent and irritating. Some common aldehydes include formaldehyde (used in building materials and as a disinfectant), acetaldehyde (found in alcoholic beverages), and benzaldehyde (used in food flavorings).

Aldehydes are important intermediates in many chemical reactions, and they are used in a variety of industrial and laboratory applications. They can be synthesized by the oxidation of primary alcohols or by the partial oxidation of hydrocarbons. The given compound is formaldehyde HCHO.

Answer:

20 grams.

Explanation:

5 mols of a compound has a mass of 100 grams

1 mol of the same compound has a mass of 100/5 = 20 grams

Explanation:

AH is negative because the reaction gives out heat (exothermic).

AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.

AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.

Answer:

uryehrufurudududjehshsyshzyyxzhsu

Answer:

1.72 M

Explanation:

Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:

Molarity = number of moles (n? ÷ volume (V)

According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.

Using mole = mass/molar mass

Molar mass of MgCl2 = 24 + 35.5(2)

= 24 + 71

= 95g/mol

mole = 58.7g ÷ 95g/mol

mole = 0.618mol

Volume of solution = 359ml = 359/1000 = 0.359L

Molarity = 0.618mol ÷ 0.359L

Molarity = 1.72 M

Answer:

Ghana Empire is was a kingdom in western Africa.

The Oyo Empire was the ancient African Kingdom is located in western Africa.

The Oyo Empire prospered on regional trade and became a key facilitator in moving slaves from Africa's interior to the coast and waiting European sailing ships, with its capital at Old Oyo near the River.

The human trade was so extensive that this region of Africa became known simply as the "Slave Coast."

Finally, despite all efforts, the Oyo Empire became a protectorate of the United Kingdom in 1888; its states ceased to exist as a superpower, and it never regained its prominence in the region.

During the colonial period, however, the Yoruba were one of Africa's most urbanized groups.

Thus, the ancient African kingdom of the Oyo Empire was located in western Africa.

Answer:

V = nRT/P

Explanation:

The ideal gas law states that

PV=nRT

where P = pressure, V = volume, n = number of moles, R = ideal gas constant, and T= temperature

P V = n R T

to get V on its own, divide both sides of the equation by P

V = (nRT)/P
