Which two element will most likely form an ionic bond

If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

Darina [25.2K]

The question is incomplete, here is the complete question:

A bottle of rubbing alcohol having aqueous solution of alcohol contains 70% (v/v) alcohol. If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

Answer: The amount of water present in the given bottle of rubbing alcohol is 283.8 mL

Explanation:

We are given:

Volume of bottle of rubbing alcohol = 946 mL

70% (v/v) alcohol solution

This means that 70 mL of rubbing alcohol is present in 100 mL of solution

Amount of water present in solution = [100 - 70] = 30 mL

Applying unitary method:

In 100 mL of solution, the amount of water present is 30 mL

So, in 946 mL of solution, the amount of water present will be = $\frac{30}{100}\times 946=283.8mL$

Hence, the amount of water present in the given bottle of rubbing alcohol is 283.8 mL

What is Potential energy

Alex_Xolod [135]

Answer:

energy that's waiting to happen

Explanation:

as an example if you throw a ball up in the air potential energy is going to happen when it comes down that's going to be energy basically I don't know if you get it but it's called potential energy

Answer:

2.Closed System: A closed system is a thermodynamic system where energy can be exchanged with its surrounding but not matter. Open System: Open systems can exchange matter with the surrounding. Closed System: Closed systems cannot exchange matter with the surrounding. Open System: The mass of the system will vary with time in open systems.

Explanation:

1.The particle model is the name for the diagrams used to draw solids, liquids and gases. In the model, the particles are shown as circles or spheres. However, the particles in ice, liquid water and steam look the same because they are all water, but in different states of matter. Why do we use the particle model in science?

3.An open system can be defined as a system which can exchange both matter and energy with the surrounding. For example, the earth can be recognized as an open system. In this case, the earth is the system, and space is the surrounding. Sunlight can reach the earth surface and we can send rockets to space.

What’s the fastest way to balance chemical equations

Anon25 [30]

Hey there!

The best way to balance chemical equations is to first start by balancing polyatomic ions such as OH and SO₄.

Next, balance other elements, but save elements that are by themselves for last, such as H₂ or Fe. Once you balance everything else you can do the ones by themselves, it's much easier.

Hope this helps!

You use an analytical balance to measure the mass of a weigh boat and record a mass of 1.5624 g. You then add some NaHCO3 to the

never [62]

Answer:

The minimum number of grams of acetic acid that we would need to fully react with your NaHCO3, is 0.263 grams.

Explanation:

Step 1: Data given

Mass weigh boat = 1.5624 grams

Mass of boat + NaHCO3 = 1.92...

Step 2: Calculate ranges

The minimum possible mass of boat + NaHCO3 = 1.9200g

Minimum mass of NaHCO3 = 1.9200g - 1.5624g = 0.3576g

The maximum possible mass of boat + NaHCO3 = 1.9299g

Maximum mass of NaHCO3 = 1.9299g - 1.5624g = 0.3675g

What is the minimum mass of acetic acid that must be used to react with all the NaHCO3 possible in the boat:

This means what mass of CH3COOH reacts with 0.3675g NaHCO3

NaHCO3 + CH3COOH → CH3COONa + CO2 + H2O

1 mole of NaHCO3 consumed, needs 1 mole CH3COOH to produce 1 mole of CH3COONa, 1 mole CO2 and 1 mole H2O

Step 3: Calculate moles NaHCO3

Moles NaHCO3 = mass NaHCO3 / Molar mass NaHCO3

moles NaHCO3 = 0.3675 grams / 84g/mol

moles NaHCO3 = 0.004375 moles

Since 1 mole of NaHCO3 consumed, needs 1 mole CH3COOH

For 0.004375 moles NaHCO3, we need 0.004375 moles CH3COOH

Step 4: Calculate mass of CH3COOH

mass of CH3COOH = moles CH3COOH * Molar mass CH3COOH

mass of CH3COOH = 0.004375 moles * 60.05 g/mol

mass CH3COOH = 0.2627 grams ≈ 0.263 grams

The minimum number of grams of acetic acid that we would need to fully react with your NaHCO3, is 0.263 grams.
