In addition to water, what are the predominant species in solution at F?

In addition to water, what are the predominant species in solution at F? Correct Answer Na+, Cl-, and H2CO3

B-At G the CO32- is now HCO3-, so no CO32- remains. The Na+ did not react, so it is still present as ions. The Cl- is from the HCl and remains as separate ions in solution. After G, the H+ from the acid begins to convert HCO3- to form H2CO3, which is complete at point F leaving no HCO3- in the solution. Other than water, all species are strong electrolytes and exist as ions in solution. The H2CO3 will be decomposing to H2O and CO2(g).

Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions. Which kind of assessment is depicted by this situation?

You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. B: The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas.  C: Endangered species may be at risk due to factors such as habitat loss, poaching, and invasive species. D: An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction.
A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y. 
Why do exotic species pose a threat to an indigenous ecosystem such as in a Lake or an isolated island in the Andamans? 1. Such species compete with the local or native species for food. 2. They may be predators of local species. 3. Such species may cause diseases in native species. Select the correct answer code:

A vessel contained a solution of acid and water, in which water was 64%. Four litres of the solution was taken out of the vessel and the same quantity of water was added. If the resulting solution contains 30% acid, the quantity (in litres) of the water in the solution, at the beginning in the vessel, was:

Ants have been living on the earth for more than 100 million years and can be found almost anywhere on the planet. It is estimated that there are about 20000 different species of ants. For this reason ants have been called Earth's most successful species. If you watch ants for any length of time you will see that they really do communicate with each other and very effectively too. Ants communicate by touching each other with their antennae. Ants also use chemicals called pheromones to leave scent trails for other ants to follow. Ants build many different types of homes. Many ants build simple little mounds out of dirt or sand. Other ants use small sticks mixed with dirt and sand to make a stronger mound that offers protection from rain. Western Harvester ants make a small mound on top, but then tunnels up to 15 feet straight down to hibernate during winter. Ant mounds consist of many chambers connected by tunnels. Different chambers are used for nurseries, food storage, and resting places for the worker ants. Some ants live in wood like termites. Army ants don't make a home at all but travel in a large groups searching for food. Ants are social insects which means they live in large colonies or groups. Some colonies consist of millions of ants. There are three types of ants in each species, the queen, the sterile female workers and males. The male ants only serve one purpose, to mate with future queen ants and do not live very long. The queen grows to adulthood, mates, and then spends rest of her life laying eggs. A colony may have only one queen, or there may be many queens depending on the species. Ants go through four stages of development: egg, larva, pupa and adult.
