The General Name For Hydrocarbons With At Least One Triple Covalent Bond Is _____. (2023)

First write the formula and make sure it is balance

MgSO4 + BaCl2 --> MgCl2 + BaSO4

then, we need to determine which reactant is the limiting reagent. using their respective molar masses.

1.20 g MgSO4 x (1 mole MgSO4/ 120.3 g)=0.00998 moles

10.0 g BaCl2 x (1 mole BaCl/ 172 g) = 0.0580 moles

Since MgSO4 give the less amount of moles, MgSO4 is the limiting reagent.

0.00998 moles MgSO4 (1 mole BaSO4/1 mole MgSO4) (233.3 g/ 1 mole BaSO4) = 2.34 grams

Explanation:

A chemical property is defined as the property that brings changes in chemical composition of a substance.

For example, flammability, combustion, reactivity, electronegativity etc are allchemical properties.

On the other hand, a property that does not bring any change in chemical composition of a substance is known as a physical property.

For example, shape, size, mass, density etc are all physical properties.

Thus, we can conclude that these may all be classified as chemical properties of a substance.

Answer:

C) chemical properties

Explanation:

These may all be classified as chemical properties of a substance. A chemical property is a property that may be observed during a chemical reaction with another substance.

Matter is anything that has mass and takes up space. It can be in the form of solids, liquids, or gases. When you look at an object, you are able to see many of its properties. Scientists classify matter based on its chemical and physical properties that have been observed and tested. Some physical properties are only known through experimentation, while others are visible to the naked eye.

A physical property is a characteristic that can be observed or measured without changing the composition of the sample. Physical properties can be used to describe mixtures as well as pure substances. Because these pure substances have uniform and unchanging compositions, they also have consistent and unchanging physical properties.

A). The number of solute particles increases

Answer:

The correct option is A

Explanation:

Electronegativity is the tendency of an atom to attract shared electron towards itself. Generally, metals have low electronegativity, this is because they have few valence electron(s) in there outermost shell and it's easier for them to lose this electron(s) than to gain electrons. Hence, Francium and Titanium are both wrong because they are both metals.

Non-metals however have an almost filled outermost shell, and hence it is easier for them to attract electron(s) than to lose. Thus, in the periodic table, electronegativity increases from left to right across the period (with group zero excluded from this trend). We can deduce from the above that halogens (in group 17) have the highest electronegativity in each period.

From the options provided, Fluorine is the answer based on earlier discussions. It should however be noted that Fluorine is the most electronegative element because it's electrons are closely bound to it's atom because the outermost shell, where the valence electrons are, is close to the centre nucleus. The force and the short distance between the positively charged nucleus and the negatively charged valence electrons makes fluorine the most electronegative element. Because it's very difficult to lose any of this electron and easier to gain an electron this way. Oxygen and Nitrogen are the next most electronegative elements because of this reasons.

The element which does not form a monatomic ion is Argon

Explanation

Argon is a group 18 ( noble gas) element.

All noble gas element are inert ( they are non reactive)

Since argon is inert, it does not form a monatomic ion since it has 8 valence electron in it's outermost energy level. ( Argon outermost energy level is fully occupied with electrons)

Answer:

3. low boiling point

Explanation:

There are primarily 4 types of intermolecular forces which exists between molecules. In the increasing strength, these forces can be grouped as:

Ionic bond > hydrogen bonds > dipole-dipole > dispersion forces

Hydrogen bond is essentially a bond formed between H-atom and a highly electronegative atom like N, O, F etc. These are strong forces of attraction. Greater the H-bonding greater is the attractive force which will result in molecules having high melting and very high boiling points. It will also increase the polarity of the molecule making it more soluble in water.

Answer:

C) The diameter of the atom decreases somewhat as electrons are added, and D) The attractive force of the nucleus increases.

Explanation:

From left to right in the period the atomic number of the element increases. This increases the number of protons in the nucleus, and thus increases the nuclear forces. Also from left to right in the period gradually more and more electrons are added. Electrons that enter the d orbital have poor shielding effect compared to the s and p block elements. The combination of poor shielding effect and the increase in nuclear charge cause the atomic radii to decrease.

Answer:

The answer is c) 1e-

Explanation:

The chemical change is the loss of 1 electron (1 e-) in 1 atom of sodium (Na) to give a sodium cation (Na⁺). You have to put the electron in the cation side of the equation. In this way, the overall process is electrically neutral (1 positive charge is neutralized by 1 negative charge and the other side has not charges):

Na → Na⁺ + 1 e-
