<span>In sanitary landfills, liquid that is produced by the interaction of rainwater with solid waste is called a leachate. This is because when rainwater makes contact with the solid wastes which are usually buried, the liquid draws out chemical constituents from those wastes. The leachate can then carry harmful substances that can seep through underground and affect groundwater.</span>

</span> All normal eggs from the mother have an X chromosome while usually half the sperm cells from the father have a Y (male) chromosome and the other half have an X (female) chromosome and it is therefore the father's sperm that dictates which gender the embryo will take.
If the egg is fertilized by a sperm with a Y chromosome then the embryo will be a genetic male due to XY chromosome combination.
<span>If the egg is fertilized by a sperm with an X chromosome then of course the embryo will be a genetic female due to XX chromosome combination.</span>
ANSWER
The correct answer is A
<u>EXPLANATION</u>
From the equation 
<u>L.H.S.</u>
Fe = 1
O =2
<u> R.H.S</u>
Fe =2
O =3
Now, let try to balance the oxygen atoms first,
To do this, we know the Least Common Multiples of 2 and 3 is 6
To get 6 atoms of oxygen at L.H.S multiply 2 by 3 and on the R.H.S, multiply 3 by 2
L.H.S.
R.H.S
This means that, 3 should be in front of 
at the L.H.S and 2 should come before 
in the R.H.S of the equation
Now, we have
L.H.S.
Fe = 1
O = 6
<u>R.H.S</u>
Fe =4
O =6
The equation is still not balanced since Fe is not balance
The Least Common Multiple of 1 and 4 is 4
Which means that we need to multiply 1 by 4 at the L.H.S and 4 by 1 at the R.H.S
L.H.S.
R.H.S
We now, have
<u>L.H.S. </u>
Fe= 4
O=6
<u>R.H.S</u>
Fe =4
O=6
Hence the balanced equation is
Answer:
Ammonia feels slippery or soapy to the touch because<u> it is an [alkaline] base and can dissolve some of the fats and oils in your skin.</u>
Explanation:
The concept <em>alkali</em> refers to salts that contain alkali and alkaline earth metal elements. According to chemists, all alkaline solutions are <u>basic</u>.
Ammonia is an alkaline solution that, when combined with water, it actually makes soap. This base feels slippery to the touch because when it makes contact with all the oils that are naturally present in your skin, it produces soap, making it slippery and soapy.
