Answer:

Before a chemical reaction happens, what should happen is:

reagent contact,
chemical affinity,
favorable collisions, and
activation energy.

Explanation:

Contact between reagents: In order for the reactant molecules to collide with each other, they must come into contact. For example, sodium is a metal element that reacts with oxygen, oxidizing in minutes when in contact with air.
chemical Affinity: This property refers to the ability of one substance to react with another, because even if two or more substances are brought into contact but there is no affinity between them, the reaction will not occur
favorable collisions: For a chemical reaction to occur, the molecules of the reagents that came in contact must effectively collide. The greater the number of favorable collisions, the faster the chemical reaction will be.
Activation Energy: For collisions to be favorable and result in a chemical reaction, the reagents must have a minimum energy, which is the activation energy. Activation energy is required for the formation of the activated complex, that is, an intermediate structure between reactants and products, where reactant bonds are being weakened and product bonds are being formed.

Page 7e) Mrs. karki deposited a sum of money 7aa in a bank at the rate of 5 90 per year Simple interest. T. She received an inte

Andre45 [30]

The principal money Mrs Karki deposited in the bank was

= Rs 1339

Simple interest (Si) received = Rs 4,740

Time (t)= 6 years

Rate (r)= 59%

Therefore the principal amount (p) =

$p = \frac{si \times 100}{r \times t}$

where,

$p = \frac{4740 \times 100}{59 \times 6}$

$p = \frac{474000}{354}$

$p = 1339$

Therefore, the principal money Mrs Karki deposited in the bank was = Rs 1339

How does the formation of oil differ from the formation of coal

Helen [10]

The formation oil, that is, sweet crude, is typically that accumulate on the seafloor and "kitchen" of the geothermal gradient to be altered in petroleum products.while Most of the coal we use now was formed about 300 million years ago, when much of the earth was covered by steamy swamps.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptat

expeople1 [14]

Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.

In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.

These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.
