1. Describe an experiment to show the chemical effect of electric current.
2. State three conditions necessary for combustion
3. Describe all that you observe when a piece of iron is placed in copper sulphate solution for a
few minutes.
Explanation:
STEP 1- Take two iron nails.
STEP 2- Clean it with sand paper.
STEP 3- Wrap copper wire around both the nails. And connect the other end to the battery terminal.
STEP 4- Take water in beaker and little amount of salt in it or a few drpos of sulphuric acid in it.
STEP 5- Immerse the nails in the solution.
STEP 6- Observe the nails carefully. You can see bubbles of gases coming out from water near nails.
When, electeric current is passed through water gases like hydrogen and oxygen are evolved.
2.Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
When iron is placed in Copper sulphate solution, the iron is coated with a brown coloured substance "copper" and CuSo4 solution changes from blue to light green. This is due to iron displaces copper as it is more reactive than copper.

Explanation:
goog le
The layer which is closest to the surface is least dense.
What are the layers of ocean?The ocean can be divided into three main layers:
The surface layer (also known as the epipelagic zone), which extends from the surface to about 200 meters deep and is the warmest and lightest layer.
The mesopelagic zone (or twilight zone), which extends from 200 to 1000 meters deep and is characterized by limited light and declining temperatures.
The bathypelagic zone (or midnight zone), which extends from 1000 to 4000 meters deep and is the coldest, darkest, and most pressure-filled layer.
Below the bathypelagic zone lies the abyssopelagic zone, which extends from 4000 to the ocean floor and is characterized by near-constant darkness and extremely cold temperatures.

How many atoms of aluminum (Al) are in 6.98 mol of aluminum?
Answer:
[tex]\boxed {\boxed {\sf 4.20 *10^{24} \ atoms \ Al }}[/tex]
Explanation:
To convert from moles to atoms, we must us Avogadro's number: 6.022*10²³. This tells us the number of particles (atoms, molecules, etc.) in 1 mole of a substance. In this case, it is atoms of aluminum.
We can use the number as a fraction.
[tex]\frac{6.022*10^{23} atoms \ Al}{1 \ mol \ Al}[/tex]
Multiply by the given number of moles: 6.98
[tex]6.98 \ mol \ Al *\frac{6.022*10^{23} atoms \ Al}{1 \ mol \ Al}[/tex]
The moles of aluminum will cancel.
[tex]6.98 *\frac{6.022*10^{23} atoms \ Al}{1 }[/tex]
The denominator of 1 can be ignored.
[tex]6.98 * {6.022*10^{23} atoms \ Al}[/tex]
Multiply.
[tex]4.203356*10^{24} \ atoms \ Al[/tex]
The original measurement of moles has 3 significant figures, so our answer must have the same.
For the number we calculated, that is the hundredth place. The 3 in the thousandth place tells us to leave the 0.
[tex]4.20 *10^{24} \ atoms \ Al[/tex]
There are about 4.20*10²⁴ atoms of aluminum in 6.98 moles.

Do you think personality
traits are primarily inherited
from your parents or
influenced by the
environment? What is your
evidence you researched?
Personality traits are influenced by a combination of genetic and environmental factors. Research suggests that both genetics and the environment play significant roles in shaping an individual's personality.
Studies on twins and adoption give proof that genetics affect personality. When opposed to fraternal twins, who only share 50% of their genetic makeup, identical twins, who share 100% of their genetic material, frequently show stronger similarities in personality traits. This shows that certain personality traits are influenced by hereditary factors.
Yet, environmental influences also have a considerable impact on personality. Despite having comparable DNA, studies on non-twin siblings reared in the same home have found that they frequently display personality differences.
This shows that the environment, including parental practices, cultural influences, and life events, has a significant impact on personality development.

Explain why the metals conduct electricity
write in your own words please, don't copy-paste from internet
Answer:
Metals conduct electricity because the electrons inside the metal are relatively free to move. So when electricity is pass through metals, electrons carry electricity and spread it all over the metal. The mobility of electrons is the reason why metals conduct electricity.

Answer:
Rate = k [X]⁻¹ [Z]²
Explanation:
[X] [Y] [Z] initial rate M M M M · s −1
Exp 1 0.30 0.20 0.35 0.210
Exp 2 0.60 0.10 0.70 0.420
Exp 3 0.60 0.20 0.70 0.420
Exp 4 0.60 0.40 0.35 0.105
In Experiment 2 and 3 where the concentrations of Y and Z were constant, doubling the concentration of Y had no effect on the rate of the reaction. This means, that the rate of the reaction is zero order with respect to Y.
In experiment 3 and 4, dividing the concentration of Z by 2, causes the rate of the reaction to decrease by 4. This means the rate of the reaction is second order with respect to Z.
In experiment 1 and 4, doubling the concentration of X, causes the rate of the reaction to decrease by half. This means that X has an order of -1 with respect to the rate of the reaction.
The rate expression is given as;
Rate = k [X]⁻¹[Y]⁰[Z]²
Rate = k [X]⁻¹ [Z]²

If 3.68 grams of zinc were allowed to react with excess hydrochloric acid to produce zinc chloride and hydrogen gas, how much zinc chloride should be produced?
Suppose that 7.12 grams of zinc chloride is actually recovered, what is the per cent yield?
Answer:
Here... Since there is excess HCl, you know the Zinc will be the limiting reagent. I was able to create the reaction equation based on the info you gave: Z + 2HCl ----> ZCl2 +2H. Now, in order to find the theoretical yield of ZCl, you need to convert Zinc from grams to moles. Do this by dividing by its molar mass (65.38), thus: 3.68 (g) / 65.38 (g/mol) = 0.056286... moles.
Now, using the balanced equation we made earlier, we see that 1 mole of Zinc creates 1 mole of ZCl2. Thus our ratio is 1:1. This makes the next step easy. Since it is 1:1, we multiply the number of moles we have of Zinc (0.056286...) by the number of moles it will create of ZCl (1). (0.056286)(1) = 0.056286 moles ZCl. Now convert this to grams by multiplying by its molar mass (136.28) and you get 7.67 grams. This is your theoretical yield. The percent yield is found by dividing the actual amount obtained (7.12 g.) by the theoretical yield (7.67 g.) then multiply that by 100%. When this is done, your Percent Yield is about 92.8%
