Nepheline a nonpartisan that survives at room temperature can be used to protect wool clothing from being eaten by moths.

serg [7]

Nephilim has very weak intermolecular forces
So on heating it directly turns gas from solid.

Nathaline is non polar
Water is polar

So it is not expected to dissolve in water.

What is the chemical formula for the compound ammonium phosphate? Use the list of polyatomic ions and the periodic table to help

Talja [164]

Answer: The correct answer is Option C.

Explanation:

We are given some polyatomic ions with their oxidation states. Polyatomic ions are defined as the ions which are formed from more than 2 atoms.

We need to find out the chemical formula for ammonium phosphate.

For this, the polyatomic ions used are:

Ammonium ion - $NH_4^+$

Phosphate ion - $PO_4^{3-}$

By using criss-cross method, the oxidation state of the ions are exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Thus, the chemical formula for this compound is $(NH_4)_3PO_4$

Hence, the correct answer is Option C.

How do you balance this: Br2 + H2O + SO2 = HBr + H2SO4

pochemuha

Answer:

Br2+ 2H2O + SO2= 2HBr + H2SO4

Let's Compare the left side of the equation to the right side of the equation.

Left: Br= 2, H= 2, S= 1, O = 1+2

Right: Br=1, H= 1+2, S=1, O= 4

We can see that only S is balanced and not the other 3 elements.

I'll try to make each element balance.

For Br; I'll multiply by 2 on the left to make it equal to the right.

For H; Since the 2 for Br on the right affected also H, that H ( for HBr) Already has a 2, but then it adds with the other H2( for H2SO4) to give a total of 4 H on the right side. But then there's only 2 H on the left. so we multiply that 2 by a 2 ( which is written infront of the H2O to give a total of 4 H on the left side.

For O; Because of the 2 infront of the H2O, it affects the O in H2O..so now we have 2 O plus the 2 O ( in SO2) to give a total of 4 O which is equal to the right side.

Cross aldol condensation reaction was carried out by reacting Acetone with Benzaldehyde in presence of sodium hydroxide. How man

natta225 [31]

Answer:

Carbons 1 and 3

Explanation:

We must remember that by definition alpha carbons are the carbon (or carbons) next to the carbon that contains the main group. In this case, the main group is the carbonyl group (C = O) in the middle of the molecule. In the acetone molecule, we have three carbons, the carbons neighboring the carbon of the carbonyl group (carbon two) will be the alpha carbons. (Red and blue carbons or carbons one and three)

See figure 1 for further explanations.

I hope it helps!
