Answer:

You can search in GOOGLE there are LOTS of IMAGES on concept MAP of PERIODIC classification of elements

ANSWER:

The answer is:-

Explanation:

Molecular MASS of co2=44gm

no. of moles(n) =given mass/molecular mass

n=22/44=1/2

1 MOLE CONTAINS 6.022×10^23 molecules

1/2 moles contains (6.022×10^23)/2molecules

=3.011×10^23molecules

ANSWER:

PLZ MARK me brainliest

Explanation:

When solute and SOLVENT mixes in a definite proportion then solution is defined,

In solution solute PRESENT in less quantity and solvent present in high quantity.

For example when a 100 gm sugar is dissolve in 1 liter of WATER then 100 gm of sugar is solute and 1 liter of water is solvent and the resultant is the solution.

The boiling POINT of alcohol in the increasing order is (1)<(2)< (3)

Option A

Explanation:

• primary alcohol has higher boiling point as compared to secondary boiling point. This is due to the property of the formation of HYDROGEN bond. For the conversion of the liquid state to the gaseous state there should be much more separation between the compounds

• as a RESULT of these two separate the two molecules of the compound more amount of ENERGY is required to break the hydrogen bond which is present in primary alcohol

To know more,

Why do primary alcohols have higher boiling points than secondary ...

Answer:

Potassium carbonate

Explanation:

Potassium carbonate (K2CO3) is a white SALT, soluble in water (insoluble in ethanol) which forms a STRONGLY alkaline solution. It can be made as the PRODUCT of potassium HYDROXIDE's absorbent reaction with carbon DIOXIDE. It presents a large capacity to absorb moisture.

ANSWER:

IDENTICAL CHARGES PLACED in CORNER

ANSWER:

if U add VINEGAR and BAKING SODA the vinegar will splash

Explanation:

Magnesium hydroxide OUGHT to be an alkali, but it is insoluble in water. Alkali as measured by PH requires that it be soluble in water. THEREFORE, magnesium ribbon when it is BURNED forms magnesium oxide, and that isn’t soluble either

Answer:

Electron orbitals which have the same ENERGY LEVELS are KNOWN as degenerate orbitals

ANSWER: SODIUM chloride

Explanation:

Answer:

Carbon dioxide is COMPOSED of one carbon atom COVALENTLY bonded to two oxygen atoms. It is a GAS (at standard temperature and pressure) that is exhaled by animals and utilized by plants during photosynthesis. Carbon dioxide, CO2, is a chemical compound composed of two oxygen atoms and one carbon atom.

ANSWER:

ANSWER:

Pyocyanin being added to protein solutions influenced the INTENSITY of the subsequent chemiluminescence caused by KMnO4. The amplitude of chemiluminescence for albumin, peptone and peroxidase decreased by 38, 39 and 42%, respectively. Pyocyanin had only a minor effect on the chemiluminescence of alcohol dehydrogenase; it decreased the intensity of the reaction by 7%. The reaction of chemiluminescence for CYTOCHROME c and lysozyme did not change in the presence of pyocyanin.

Explanation:

Gene duplication has long been recognized as a potential source of EVOLUTIONARY NOVELTY (Ohno, 1970). ... When this subfunctionalization or neofunctionalization occurs, the same evolutionary mechanisms that would apply to any single gene also occur. PROTEIN sequence might change; REGULATORY sequences might be ALTERED.

In the REDUCTION of NITRIC oxide, 50% of reaction was completed in 108 seconds when initial pressure was 336 mm Hg and in 147 seconds initial pressure was 288 mm Hg. FIND the order of the reaction.

ANSWER:

The answer is a OPTION A

Answer:

Tick the correct answer:

1. III) Sublimation

2. iii) Physical change

3. iii) Ag

True or False:

1. True.

2. False. In an ENDOTHERMIC reaction, HEAT is absorbed.

3. False. The substances formed in a chemical reaction are CALLED products.

Answer the following questions:

1. Carbon dioxide is present in aerated drinks. When thermal energy is added to a substance, automatically, the physical state changes. Temperature, Pressure are physical factors that affect the states of matters.

2. Evaporation:

• Surface phenomenon
• Natural change

Boiling:

• Bulk phenomenon
• Human-made change.

ANSWER:

All the matter is MADE up of indivisible particles known as "ATOMS". Atoms are the structural units of an element/ matter and they can not be further DIVIDED. ... In FACT, now they are atoms of Hydrogen and oxygen which can not be further broken down. Therefore, we can say that atoms are the "building blocks" of matter

ANSWER:

MAKE sure that all words are SPELLED correctly.

Answer:

In PHYSICAL chemistry, extent of reaction is a quantity that measures the extent in which the reaction proceeds. It is usually DENOTED by the GREEK LETTER ξ. The extent of a reaction has units of amount (moles).

Answer:

Sedimentation is process in which particle tends to settle down at the bottom of water body . Example of sedimentation are :- tea LEAVES SETTLING down on cup of tea, SOIL settling in pond water etc. Decantation is the separation process of two immiscible LIQUID mixture or SOLID and liquid mixtures

Answer:

At MEAN position

due to momentum conservation

first speed increases due to RESTORING force, then GRADUALLY the direction of force CHANGE to OPPOSITE direction of movement and at that point body is in maximum velocity and that point in SHMis the mean position
