(C)I THINK it should be the ANSWER

The ANSWER is OPTION a) SOLID

ogeneous MIXTURE (by APPEARANCE) is OBTAINED.

Le Chatelier's principle implies that a PRESSURE increase shifts an equilibrium to the side of the reaction with the FEWER number of MOLES of GAS, while a pressure decrease shifts an equilibrium to the side of the reaction with the greater number of moles of gas.

zinc is an amphoteric OXIDE....plz MARK as BRAINALIST

Explanation:Solubility of the most of the salt rises with increase in temperature.This is because with increase in temperature, kinetic energy of the molecules increases and the solvent molecules break apart the SOLUTE molecules that are held together by intermolecular attractions more EFFECTIVELY. ALSO for most of the ionic compounds, change in enthalpy is positive and hence the DISSOLUTION PROCESS is endothermic. For endothermic reaction, increase in temperature leads the reaction to forward reaction.

Destructive-distillation definitions. Filters. A process by which organic SUBSTANCES such as WOOD, coal, and oil shale are decomposed by heat in the absence of air and distilled to produce USEFUL PRODUCTS such as COKE, charcoal, oils, and gases. noun. 13.

Then hydrogen GAS gets collected in the gas jar by DOWNWARD displacement of water. If the reaction is slow then we can add a little copper sulphate SOLUTION to ACCELERATE the reaction.

Let the two OXIDES by cu be A and BOxide A:-Mass of Cu in 1g=0.888gMass of O in 1g=1−0.888=0.112gOxide B:-Mass of Cu in 1g=0.799gMass of O in 1g=1−0.799=0.201gIn oxide A:- 0.112× 0.8881 =0.126gIn oxide B:- 0.201× 0.7991 =0.252gSo, 0.126 and 0.252 are the figure of Cu combined with oxygen in both the oxides.∴ Ratio=0.126:0.252or 1:2∴ This is a simple whole ratio that shows that ARGUMENT with the LAW of MULTIPLE PROPERTIES.

tion:Both NH3 and H2O are AMPHOTERIC (they have H atoms that can be DONATED as H+ ions and thus ACT as acids and lone-pair electrons that can accept an H+ and thus act as BASES). Thus, either NH3 or H2O can act as an acid or a base.

tion:Sieving: The process of separating fine particles from the larger particles by using a SIEVE, is called sieving. This METHOD is used in a FLOUR mill where IMPURITIES like HUSK and stones are removed from wheat before grinding it.

If our CONTENT about WRITING 742 as a power of 10 has been USEFUL to you,

r 1 :-❒ Explanation :-Cl₂ , Br₂ and I₂ are Homonuclear diatomic molecule in which electronegativity of the combining atoms is same. So they are more stable and less reactive, whereas I and Cl have different electronegativities and bond between them are polarized,Hence reactive therefore interhalogen COMPOUNDS are more reactive.★ Time saving technique :In this type of question of halogen only go through the polarity of molecule. As we know, diatomic molecule does not have polarity but MOLECULES with dissimilar sizes have polarity resulting in more reactivity.⇝ Answer 2 :-❒ Explanation :-H₂O₂ can act as an oxidising as well as reducing agent, because oxidation NUMBER of oxygen in H₂O₂ is -1 so it can be oxidized to Oxidation State 0 or can be reduced to Oxidation State -2 .H₂O₂ decomposes on exposure to light. So it has to be stored in plastic or wax lined glass bottles in dark for the prevention of exposure. It also has to be kept away from Dust

FFICIENT OF LINEAR thermal expansion (CTE, a, or a1) is a material property that is indicative of the extent to which a material expands upon heating. Different substances expand by different AMOUNTS. Over small temperature ranges, the thermal expansion of uniform linear objects is proportional to temperature change. Thermal expansion finds USEFUL application in bimetallic STRIPS for the construction of THERMOMETERS but can generate detrimental internal stress when a structural PART is heated and kept at constant length.

Primates have modifications to their ulna and RADIUS (BONES of the lower arm) allowing them to turn their hand WITHOUT turning their elbow. Many primates can also swivel or turn their arms at the shoulder. These two adaptations offer advantages to life in the trees.Primates have five digits on their forelimbs. They are able to grasp objects with their forelimbs in what is known as a prehensile movement. A second modification makes one of the digits opposable, allowing the tips of the fingers and thumb to touch.Placement of the eyes on the front of the head increases depth perception, an advantageous trait in tree-dwelling primates. Changes in the location of rods and cones in the eye adapted primates for color vision as well as peripheral vision in dim light.Upright posture allows a primate to view its surroundings as well as to use its hands for some other task. Hominids, the lineage leading to humans, had changes in the shape and size of their pelvis, femur, and knees that ALLOWED bipedalism (walking on two legs). The change from quadruped to biped happened in stages, culminating in humans, who can WALK or run on two legsExplanation:HEHE
