Impossible to form from given reactants

Explanation:

Only sodium has carbonate ion here .so only possible way to displace carbonate is to use potassium

When sodium carbonate and Potassium iodide react with each other double displacement reaction occurs

As potassium is powerful than sodium it displaces sodium to form potassium carbonate .

Then you have to use water and then you can use calcium suppliment .

Answer:

  • Calcium chloride
  • Sodium carbonate

Explanation:

The reaction :

<u>CaCl₂ + Na₂CO₃ ⇒ CaCO₃ + 2NaCl</u>

<u />

This is clearly an example of a displacement reaction, where sodium displaces calcium in calcium chloride to form sodium chloride, and we are left with calcium carbonate.

A team of scientists is conducting tests to measure the boiling point of a liquid using a thermometer in the liquid. The team is
NISA [10]

The most reasonable step to take will be to check the calibration of the

thermometer to ensure that it is giving accurate readings.

Experiments which are done to be give the same results under standard

conditions. Common causes of incorrect results during the analysis of

boiling point of substances include heating the substance too rapidly or

the thermometer not being properly calibrated.

The thermometer is used to measure the temperature and so must be

properly calibrated to give accurate readings.

The ozone "hole" over Antarctica formed as the result of a series of chemical reactions. The loss occurs in part through three c
mixer [17]

Answer:

A)

Cl + O3 --> ClO + O2

2ClO --> ClOOCl

ClOOCl --> 2 Cl + O2

B)

Cl2 + 4O3 -> 2 ClO + 5O2

Explanation:

Step 1: Chlorine atoms react with ozone (O3) to form chlorine monoxide and molecular oxygen

Cl + O3 --> ClO + O2

Step 2: Chlorine monoxide molecules combine to form ClOOCl gas

2ClO --> ClOOCl

Step 3: ClOOCl absorbs sunlight and breaks into chlorine atoms and molecular oxygen

ClOOCl --> 2 Cl + O2

B) Overall Balanced equation

Cl2 + 4O3 -> 2 ClO + 5O2

What adaptations of the harpy eagle allow it to be such a successful rainforest predator?
IgorC [24]
The ranking of most eagles in the food chain is at the top. They are called apex predator.

The harpy eagle is one of the largest eagle there is. Common to most eagles are its sharpness of their vision. Most eagles use it to sight their predator while circling above the ground at a distance unseen by the prey. However, harpy eagles adapted a way of hunting prey which is called perch-hunting.

Perch-hunting is a way of looking for predator by scanning the trees for prey by flying in short distances from a tree to another tree. The harpy eagle developed this skill since it is hard to sight a prey in a rain forest because of the leaves and trees blocking its vision. Hence, perch-hunting is very apt for the scenario of a rain forest eagle.
