If you move from the equator to a location in the mid-latitudes, the wintertime average temperature will _____, and the temperature range will _____.

Answers

Answer 1

If you progress from the equator to a location within the mid-latitudes, the wintertime average temperature will decrease, and thus the temperature range will increases.

What is the relationship between latitude and temperature?

As latitude increases, the temperature falls, and therefore the other way around. Generally, round the world, it gets warmer towards the equator and cooler towards the poles.

However, other factors could influence the temperature in several locations like altitude, precipitation, and ocean currents

Why is it called latitude?

On a map where north is up, latitudes run laterally (left to right). they're named after the angle created by a line connecting the latitude and the center of the Earth, and therefore the line connecting the equator and the center of the Earth. Latitudes specify the north-south position of a location on the world .

What concentration gradients are established and maintained by the sodium-potassium exchange pump?.

Answers

The concentration gradients are established and maintained by the sodium potassium - potassium exchange pump is the concentration of potassium (k+) is found higher inside the cell (neuron) and the concentration of sodium (Na+) is found higher outside the cell.

The sodium - potassium pump is an active transport that exchange sodium ions for potassium ions.Active transport is the energy - requiring process of pumping molecules and ions across membranes , against concentration gradient.

To move molecules against the concentration gradient , carrier protein is needed.The Na / K+ pump use the energy of ATP molecule to exchange the ions.

The Na+ / K+ Pump goes through cycles to maintain a negative membrane potential.Three sodium ions exit the cell while two potassium ion enters in the cell for every single ATP consumed.

Thus , the sodium - potassium pump maintains the gradient of high concentration of N+ extracellularly and high level of K+ intracellularly.

Determine the empirical formula of a compound containing 48.38 grams of carbon, 6.74 grams of hydrogen, and 53.5 grams of oxygen.

in an experiment, the molar mass of the compound was determined to be 180.15 g/mol. what is the molecular formula of the compound?

do not send links as an answer

Answers

Answer:

First, I will convert from grams to moles. This will give me approximately 4.032 moles of carbon, 6.740 moles of hydrogen, and 3.344 moles of oxygen. Then, I will calculate the mole ratio, using whole numbers. I must also identify the least amount of moles in an element for this step, which is oxygen at 3.344 moles.

Oxygen = 3.344/3.344 = 1

Carbon = 4.032/3.344 = 1

Hydrogen = 6.740/3.344 = 2

The empirical formula will be COH2.

Now that we have the molar mass of the molecular formula, we can calculate for the molecular formula. First, we will begin by discovering the molar mass of the empirical formula, which will be C molar mass x 1 + O molar mass x 1 + H molar mass x 2. That will be equal to 60.949. After that, we can divide the molecular mass by the empirical formula molar mass, giving us approximately 3. Now we will multiply the empirical formula by 3, giving us our molecular formula, which will be equal to C3O3H6.

The orbitals that overlap to form the c-h bond in ethene (h2c=ch2) is  s-sp2. The correct option is d.

What are orbitals?

Orbitals are wave functions that are the places where the electrons can be found. There are different orbitals present. These are s, p, d, and f. Orbitals are of different shapes. Round orbital and eight-like shapes.

Each carbon atom is joined to two hydrogen atoms in the ethylene molecule. Therefore, for the C-H sigma bonds in ethylene, overlap two sp2-hybridized orbitals with the 1s orbitals of two hydrogen atoms.

25.0 ml is taken from a stock solution of concentration 14.9 g/l and added to a 250.0 ml volumetric flask and diluted up to the calibration mark. what is the new concentration (in grams per liter)?

Answers

If 25.0 ml is taken from a stock solution and added to volumetric flask and diluted up to the calibration mark, then the new concentration will be 1.49 g/L.

Now, Concentration of solution is defined as amount of solute present in specific volume of the solution.

Molarity (M) = moles of solute ÷ litres of solution

Here, the concentration of solution is given as, 14.9 g/l

and, the volume of solution is 25.0 ml= 0.025 l

using the equation,

   14.9 = moles of solute ÷0.025

   moles of solute = 0.3725 moles

0.025 l is added to a 0.25 l (250.0 ml =0.25 l) volumetric flask and diluted up to the calibration mark.

Since,

volume of solution = volume of flask

And, moles of solute remains the same.

Therefore,

The new concentration is,

concentration = (0.3725 ÷ 0.25) g/l

New concentration = 1.49 g/l

Answers

The mass ratio (Mass of Q/ Mass of A) of the compound A₂Q₃ is 0.861.

mass ratio is a degree of the performance of a rocket. It describes how a lot greater big the car is with propellant than with out; this is, the ratio of the rocket's moist mass (vehicle plus contents plus propellant) to its dry mass (car plus contents). A extra green rocket layout calls for less propellant to gain a given intention, and would consequently have a lower mass ratio; but, for any given efficiency a better mass ratio usually permits the vehicle to obtain higher delta-v.

Given,

The mass ratio (mass Q)/(mass A) for AQ is 0.574  

We have to find the mass ratio (mass Q)/(mass A) of A₂Q₃.

The mass ratio for  A₂Q₃ is

Mass of Q/ Mass of A = 3 × mass Q/ 2 × mass A

Or, Mass of Q/ Mass of A = (3/2) × (mass Q/ mass A)

Or, Mass of Q/ Mass of A = (3/2) × 0.574

Or,  Mass of Q/ Mass of A = 0.861.

Therefore, the mass ratio for (Mass of Q/ Mass of A) for A₂Q₃ is 0.861.

Answers

We use laundry detergent as a liquid or powder because powder and liquid detergents have more enzymes.

What is detergent?

When present in diluted solutions, a surfactant or combination of surfactants has the ability to clean.There are many different types of detergents; one popular family is the alkylbenzene sulfonates, which are soap-like substances that are more soluble in hard water because the polar sulfonate in detergents is less likely to bind to calcium and other ions found in hard water than the polar carboxylate in soap.

Detergents in both powder and liquid form contain additional enzymes and surfactants that break down grease and slime on clothing. Additionally, because the molecules of liquid and powder soaps can move more freely than those of solid bar soap, it is simpler for them to function as nonionic surfactants.

Answers

To prepare 128.2ml of a 0.364 M aqueous solution of NaCl.the mass in grams, of NaCl need to use to make the solution is 2.723 gm.

Molarity is defined as the no. of moles of solute per liter of solution.

Here,

Molarity =  moles of solute / Liter of solution

0.36 M solution will contains 0.364 moles of NaCl.

therefore, volume of solution in L =  ( 128.2 / 1000 ) L × 1 L

                                                 = 0.1282 L

that means, it will contain, no. of moles of NaCl

= (0.1282 L of solution × 0.364 ) / 1 L of solution      

= 0.0466 moles of NaCl

now, molar mass of NaCl  = 58.44 g/mol    

so, 1 mol of NaCl has a mass of  58.44 g/mol

therefore, 0.0466 moles of NaCl will have mass of

= ( 0.0466 moles of NaCl × 58.44 g ) / 1 mole of NaCl

= 2.723 g
