Sam pipettes out 10 mL of 1.5 M AgNO3 solution and dilutes it to make the total volume of 30 mL. What is the concentration of the new solution?

Answers

Answer 1

The new concentration (molarity) of the solution is 0.5M.

According to this question, Sam pipettes dilutes 10ml of a 1.5 M AgNO3 solution with water until the final volume is 30 ml.

Formula =

C1V1 = C2V2

Where;

C1 = initial molarityC2 = final molarityV1 = in initial volumeV2 = final volume

1.5 × 10 = 30 × C2

15 = 30C2

C2 = 15/30 = 0.5M

Therefore, the new molarity of the solution is 0.5M.

Suppose a runner completes a 10K (10.0 km) road race in 45 minutes and 35 seconds.

What is the runner's average speed in miles per hour?

Answers

The average speed of the runner in miles per hour would be 8.18 miles per hour.

What is the average speed?

The average speed of a moving object is the ratio of the total distance traveled by the object and the total time taken to cover the distance. Mathematically, this can be expressed as;

Average speed = total distance traveled/ total time taken

In this case;

Total distance = 10 km

Total time = 45 minutes, 35 seconds

In order to find the average speed in miles per hour, let's convert the distance from km to mile and the time to hour.

1 km = 0.621371 mile

10 km = 10 x 0.621371

          = 6.21371 miles

1 hour = 3600 seconds

60 seconds = 1 minute

45 minutes = 45 x 60

                    = 2700 seconds

Total time = 2700 + 35

                 = 2735 seconds

3600 seconds = 1 hr

2735 seconds =  2735/3600

                         = 0.7597 hour

The average speed of the runner in miles per hour:

6.21371/0.7597 = 8.18 miles per hour

What is double displacement reaction?

When two reactants change ions to create two new compounds, the reaction is referred to as a double displacement reaction. Double displacement reactions usually result in the development of a precipitate as a product.

The positive-charged cations and negative-charged anions of the reactants swap places (double displacement) to generate two new products in this sort of reaction. Also called: A metathesis reaction or a double replacement reaction are other names for a double displacement reaction.

The equation becomes:

AlBr₃ + K₂SO₄ → KBr + Al₂(SO₄)₃

Aluminium bromide (AlBr₃) reacts with potassium sulphate (K₂SO₄) to form potassium bromide (KBr) along with aluminium sulphate (Al₂(SO₄)₃).

Balanced reaction becomes:

2AlBr₃ + 3K₂SO₄ → 6KBr + Al₂(SO₄)₃

2 mol      3 mol       6 mol    1 mol

In this reaction, two moles of aluminium bromide react with three moles of potassium sulphate to produce six moles of potassium bromide along with one mole of aluminium sulphate.

What is the role of K + ion channels in an action potential?

Potassium channels play a role in repolarization of the membrane, which follows membrane depolarization by Na, and in some cases Ca, channels during the action potential; this is necessary for returning the membrane to a negative potential to terminate the action potential signal.

What effect does opening K+ channels have on membrane potential?

It's a great day at the beach, and you're there for some fun and sun! One reason the day is so special is that the weather is so pleasant—sunny and warm. Energy from the sun warms the beach with Radiation. The breeze is warm enough to keep you warm, but it also keeps you from overheating. Ocean breezes move because energy is Convection. When you lie down on the sand, you spread a beach towel down so that the sand will not make you too hot by transferring heat by Conduction.

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field.

Heat is transferred through convection, which is the large-scale movement of molecules inside gases and liquids. Conduction is used to move heat from the object to the fluid initially, but fluid motion is responsible for the bulk of the heat transfer.

Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced.

How much energy is required to heat 100g of water at 25°C to steam at 125°C?

Answers

The amount of energy required to heat 100 g of water is 268000 J.

What is energy?

Energy is the ability or the capacity to perform work.

To calculate the amount heat energy required to change the water to steam, we use the formula below.

Formula:

Q = CmΔt+cΔt........... Equation 1

Where:

Q = Amount of energym = Mass of the waterΔt = Change in temperature of the waterc = Latent heat of vapourization of waterC = Specific heat capacity of the water

From the question,

Given:

m = 100 g = 0.1 kgΔt = 125-25 = 100 °CC =  4200 J/kg°C. c = 2260000 J/kg

Substitute these values into equation 1

Q = (0.1×100×4200)+(2260000×0.1)Q =  42000+226000Q = 268000 J

How amino acids take part in salt-bridge formation?

Two non-covalent interactions—hydrogen bonding and ionic bonding—combine to form a salt bridge. One of the most significant noncovalent forces in chemistry and in biological systems is ion pairing. In a normal acid-base neutralization process, amino acids interact with one another to create salt. Simple attraction between the positive and negative charges and the shift of the -H (positive ion) from the acid to the amine constitute the reaction.

Amino acids that take part in bridge formation are- The anionic carboxylate (RCOO) of either aspartate or glutamate and the cationic ammonium (RNH3+) from lysine or the guanidinium (RNHC(NH2)2+) of arginine most frequently form the salt bridge.
