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 />

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.

Which scenario best exemplifies the way a signal is passed down an axon coated with myelin sheath?

goblinko [34]

Runners sprinting short distances in a relay race and handing off a baton scenario best exemplify the way a signal is passed down an axon coated with a myelin sheath.

Axons are long extensions of neurons (or nerve cells) involved in the transmission of nerve impulses away from the cell body. Each nerve cell has an axon that is over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the ends of the axon.

Each neuron in the brain has long cables that meander from the body of the cell. These cables, several times thinner than human hair, are called axons and are where electrical impulses leave neurons and are received by other neurons.

there are 1540 megawatts of wind-generated electricity produced globally every year. This amount is equivalent to how many kilow

Reptile [31]

1.54 x 10⁶kW

Explanation:

The problem here is converting from megawatts into kilowatts.

Given 1540megawatts.

The mega- and kilo- watts are prefixes that denotes multiples of units.

1 megawatt = 10⁶watts

1 kilowatt = 10³watts

Now given 1540megawatts power to Kilowatt power;

We see that :

1000kW = 1mW

1540mW x $\frac{1000kW}{1mW}$ = 1.54 x 10⁶kW

Write the condensed formula from left to right, starting with (CH3)x where x is a number.

pochemuha

Complete question:

Write the condensed formula from left to right, starting with (CH3)x where x is a number.

See attached image for the structure formula of the compound

Answer:

(CH₃)₂CHC(CH₃)₃ named as 2,2,3-Trimethylbutane

Explanation:

If we number the longest chain of the carbon starting from the left, we will observe that there are four carbons in the straight chain as shown in the image.

Starting from first carbon from the left of the carbon chain, at carbon number number 2, there two alkyl group, that is two methyl (CH3 is two). Also at carbon number 3, there are three alkyl group, that is three methyl (CH3 is three).

The condensed formula will be written as;

(CH₃)₂CHC(CH₃)₃

This compound is named as 2,2,3-Trimethylbutane, an isomer of Heptane
