In a fair test, you should change only one variable so that you can see the effects of the variable you changed. Suppose you wer

Answer:

<em>a) The variable that we will change will be the different liquids.</em>

<em>b) The variable which will be kept same will be the ramp angle, the time for measuring in each experiment and the heat. </em>

Explanation:

In a scientific experiment, an independent variable is a variable which is changed by the researcher so that its effect on the dependent variable can be studied.

A dependent variable is a variable which is under study and might be influenced by changes in the independent variable.

It is best to study the effect of a single independent variable at a time so that we can easily infer the results.

<u><em>In the scenario discussed in the question, we would change the different liquids so that the time taken by each liquid to flow down the ramp can be studied.</em></u>

<u><em>We will keep the ramp angle, the time (of each experiment) and heat for each of the experiments the same so that a just conclusion can be drawn.</em></u>

How much energy is released by the decay of 3 grams of 20Th in the following reaction 230 Th - 226Ra + 'He (230 Th = 229.9837 g/
wolverine [178]

Answer : The energy released by the decay of 3 grams of 'Th' is 2.728\times 10^{-15}J

Explanation :

First we have to calculate the mass defect (\Delta m).

The balanced reaction is,

^{230}Th\rightarrow ^{226}Ra+^{4}He

Mass defect = Sum of mass of product - sum of mass of reactants

\Delta m=(\text{Mass of Ra}+\text{Mass of He})-(\text{Mass of Th})

\Delta m=(225.9771+4.008)-(229.9837)=1.4\times 10^{-3}amu=2.324\times 10^{-30}kg

conversion used : (1amu=1.66\times 10^{-27}kg)

Now we have to calculate the energy released.

Energy=\Delta m\times (c)^2

Energy=(2.324\times 10^{-30}kg)\times (3\times 10^8m/s)^2

Energy=2.0916\times 10^{-13}J

The energy released is 2.0916\times 10^{-13}J

Now we have to calculate the energy released by the decay of 3 grams of 'Th'.

As, 230 grams of Th release energy = 2.0916\times 10^{-13}J

So, 3 grams of Th release energy = \frac{3}{230}\times 2.0916\times 10^{-13}J=2.728\times 10^{-15}J

Therefore, the energy released by the decay of 3 grams of 'Th' is 2.728\times 10^{-15}J

Ionic compounds form because ___ charges attract
notsponge [240]

Answer:

Ionic bonding is the attraction between positively- and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.
