Answer:

Mass% of calcium is 36%

Mass% of chlorine is 64%

Explanation:

15g of compound has 5.41g Ca.

100G of compound will have 36g of Ca

We know mass% of a compound is the amount of substance(in Gram) present in 100g of compound.

So 36% similarly mass% of CL is 64%

ANSWER:

Hint: Diffusion is the net movement of anything from a region of HIGHER concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. Sublimation is the transition of a substance directly from the solid to the gas state.

Complete step by step solution: Naphthalene BALLS disappear with time without leaving any solid. Naphthalene undergoes sublimation easily i.e., the change of state of naphthalene from solid to gas without the intervention of the liquid state. Thus, naphthalene balls keep on forming naphthalene vapours which disappear into the air with time without leaving any solid.

We can get the smell of perfumes sitting several meters away. Perfume has a higher DEGREE of vaporization and its vapour diffuses into the air easily. Gaseous particles possess high speed and move very rapidly in all directions. When perfume is sprayed, its particles diffuse into the particles of air at a very fast rate and reach our nostrils. This enables us to smell the perfume from a distance.

When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. The particles of smelly gas are free to move quickly in all directions. They eventually spread through the whole room from an area of high concentration to an area of low concentration.

Note: Sublimation is a type of phase transition, or a change in a state of MATTER, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.

Answer:

When there is not enough of one reactant in a chemical reaction, the reaction stops abruptly. To figure out the amount of product produced, it must be determined reactant will limit the chemical reaction (the limiting reagent) and which reactant is in excess (the excess reagent). One way of finding the limiting reagent is by calculating the amount of product that can be formed by each reactant; the one that produces less product is the limiting reagent.

Explanation:

The following SCENARIO illustrates the significance of limiting reagents. In order to assemble a car, 4 tires and 2 HEADLIGHTS are needed (among other things). In this example, IMAGINE that the tires and headlights are reactants while the car is the product formed from the reaction of 4 tires and 2 headlights. If you have 20 tires and 14 headlights, how many cars can be made? With 20 tires, 5 cars can be produced because there are 4 tires to a car. With 14 headlights, 7 cars can be built (each car needs 2 headlights). Although more cars can be made from the headlights available, only 5 full cars are possible because of the limited number of tires available. In this case, the headlights are in excess. Because the number of cars formed by 20 tires is less than number of cars produced by 14 headlights, the tires are the limiting reagent (they limit the full completion of the reaction, in which all of the reactants are USED up).

Explanation:

We can rewrite this expression to obtain the equation of angular VELOCITY: ω = r × v / |r|² , where all of these variables are vectors, and |r| denotes the absolute value of the radius. Actually, the angular velocity is a pseudovector, the DIRECTION of which is PERPENDICULAR to the plane of the rotational movement

Answer:

ELECTROCHEMICAL series also sometimes referred to as activity series is a LIST that describes the arrangement of elements in order of their increasing ELECTRODE potential VALUES. The series has been established by measuring the potential of VARIOUS electrodes versus standard hydrogen electrode (SHE).

(C)CHANGES with CHANGE of CONCENTRATION of ELECTROLYTE

Answer:

change in which one or more new SUBSTANCES are formed is known as chemical change.

For Example, when the iron is exposed to air and MOISTURE, rust formation takes place. Rust is nothing but Iron Oxide; a new substance formed out of the reaction. The COLOUR of the surface of the iron also changes. HENCE, rusting of iron is a chemical change.

Answered by Rohith kumar. R. maths dude

▪Let ,

•A=FIRST group wins

•B= second group wins

•C=new PRODUCT is introduced

●We want to FIND the probability that the new product introduced by second group .

▪Hence we take ,

●P (F|<U>G) =P (F).P (F|G)/P (E).P (G|E +P (F).P (G|F)

▪P.E=Probability of first group wins =0.6.

▪P(E|G)=0.7.

▪P (B)=Probability that the second group wins =0.4

▪P (G|F)=0.3.

☆Putting the values in the given formula

☆P (F|G)= 0.4×0.3 /0.6×0.7+0.4×0.3

☆P (F|G)= 0.12 /0.42+0.12

☆P (F|G)= 0.12 / 0.54

☆P (F|G)= 2 /9

☆☆Therefore ,

☆The required Probability is 2 /9

☆Hope it helps u mate.
