He conjugate pair for a weak acid is--

Answers

Answer 1

Answer: The stronger acid, however, is on the left side of the equation. The general rules suggest that the stronger of a pair of acids must form the weaker of a pair ofconjugate bases. The fact that HCl is a stronger acid than the H3O+ ion implies that the Cl- ion is a weaker base than water.

A sample of sodium hydroxide (NaOH) has a mass of 160.0 g. The molar mass of NaOH is 40.00 g/mol. How many moles of NaOH does this sample contain?A) 4.000
B) 40.00
C) 160.0
D) 6,400

Answers

The correct answer is A. A sample of sodium hydroxide (NaOH) has a mass of 160.0 g which is equal to 4 moles of NaOH. TO calculate this, we use the relation of the molar mass given.

160.0 g NaOh ( 1 mol NaOH / 40.0 g NaOH ) = 4.000 mol NaOH

The answer is a because all you have to is 160*1/40=4.000

In the process of electrolysis, current can flow through a liquid because A. water molecules become negatively charged. B. hydrogen is electrically neutralized in the solution. C. negative ions are attracted to the anode. D. cations of the electrolyte accumulate at the positive electrodes.

Answers

B. Hydrogen is electrically neutralized in the solution. Hydrogen is a chemical element with symbol H and atomic number 1. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table.

The correct answer is

C. Negative ions are attracted to the anode.

How can a mixture of nails and sawdust be most efficiently separated into its component parts?

Answers

I am pretty sure that sawdust float in water so you could dump the mixture in water so that all of the sawdust float on the surface while the nails sink to the bottom.

You might also be able to use a strong magnet since nails are usually magnetic while sawdust is not.

I hope this helps. Let me know if anything is unclear or if you need a different method.

How many grams of Ny must react to form 1.7 grams of ammonia, NH3?
0.052 g
1.49
0.00589
2.8 g

Answers

Answer:

Explanation:

Here we have to use stoichiometry.

First of all, we have to calculate the mass of 100% of yield:

1.7 g ------- 98%

X -------- 100%

X = 1.73 g (approximately)

Second, we have to calculate the mass of N2 that is necessary to react to produce the mass of 1.73g of NH3. To do that, we have to use the Molar mass of N2 and NH3 and don't forget the stoichiometric relationship between them.

Molar Mass N2 : 14x2 = 28 g/mol

Molar Mass NH3: 14 + 3 = 17 g/mol

28g (N2) ------- 17x2 (NH3)

X ------------ 1.73 g

X = 1.42 g (approximately)

In a laboratory experiment, John uses a mesh to separate soil particles from water. Which technique of separation is he using?

Answers

He is using filtration technique

It's a technique which is used for separation of solids and fluids by putting them through a medium which allow only fluid to pass through, leaving the solids (in this case the soil) alone.

The fluid that passed is called the filtrate
