100 cm is meter stick.

Centimeter is denoted by the (cm). It is a metric unit of the measurement which is used for measuring the length of an object.

Meterstick is a foldable ruler which is used to measure the length, and it is common in the construction industry. They are made up of wood or plastic and often they have a plastic or metal joints so that they can be folded together.  

A meter measuring stick, which is one meter (39.37 inches) long, it contains 100 centimeters. Thus, centimeter is equal to one-hundredth of a meter. The word centimeter comes from the late 18th-century. The word centimeter derived from the Latin root "centum"/ means "hundred" and the Greek root "metron", meaning "measure".

the partial pressure of gas A in the total volume is 3.57 bar, and the partial pressure of gas B in the total volume is 0.70 bar.

When the gases are allowed to mix together, the total pressure of the mixture is equal to the sum of the partial pressures of each gas. The partial pressure of each gas is equal to the product of the total pressure and the mole fraction of that gas. To find the mole fraction of each gas, we first need to find the number of moles of each gas. The number of moles of gas in container A is given by PV/RT where P is the pressure, V is the volume, R is the ideal gas constant and T is the temperature.

n_A = (2.90 bar * 747 mL) / (8.314 J/molK * (273.15 + 23)) = 0.0295 mol

The number of moles of gas in container B is given by PV/RT

n_B = (4.30 bar * 119 mL) / (8.314 J/molK * (273.15 + 23)) = 0.0045 mol

The total number of moles of gas in the mixture is the sum of the number of moles of gas in container A and container B.

n_total = n_A + n_B = 0.0295 mol + 0.0045 mol = 0.0340 mol

The mole fraction of gas A in the mixture is the number of moles of gas A divided by the total number of moles of gas.

x_A = n_A / n_total = 0.0295 mol / 0.0340 mol = 0.8735

The mole fraction of gas B is

x_B = n_B / n_total = 0.0045 mol / 0.0340 mol = 0.1324

The partial pressure of gas A is equal to the total pressure multiplied by the mole fraction of gas A.

P_A = (0.8735) * (2.90 bar + 4.30 bar) = 3.57 bar. The partial pressure of gas B is equal to the total pressure multiplied by the mole fraction of gas B. P_B = (0.1324) * (2.90 bar + 4.30 bar) = 0.70 bar

So the partial pressure of gas A in the total volume is 3.57 bar, and the partial pressure of gas B in the total volume is 0.70 bar.

The pressure of N2O gas at a density of 3.10 g/L and a temperature of 298 K is 751 mmHg. To calculate the pressure of the N2O gas at a given density and temperature, we can use the ideal gas law: PV = nRT.

We know that the density of the gas is 3.10 g/L, and the temperature is 298 K. To find the pressure, we can assume that the volume of the gas is 1 L, and solve for pressure. where P is the pressure of the gas, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

The density of a gas can be converted to moles using the formula:

Density = m/V

m = Density*V

Now we can use the ideal gas law to calculate the pressure:

P = (mRT)/V

R is the ideal gas constant = 0.0821 L atm K^-1 mol^-1

P = (3.10g0.0821 L atm K^-1 mol^-1298 K)/1 L

The density of the metal beads, given that total mass of the metal plus alcohol in the flask was determined to be 38.6794 g is 3.22 g/mL

We'll begin by obtaining the density of the alcohol in the flask with the metal beads. This is illustrated below:

Density = mass / volume

Density of alcohol = 19.7325 / 25

Density of alcohol = 0.7893 g/mL

Next, we shall determine the volume of the alcohol in the 25 mL flask. This can be obtained as follow:

Volume = mass / density

Volume of alcohol in flask = 13.5734 / 0.7893

Volume of alcohol in flask = 17.2 mL

2H2 + O2 -> 2H20 is the balanced equation for the reaction of Hydrogen with Oxygen to form water so

If you have 32g of O2 this is a simple Dimensional analysis problem

32g O2 x 36.03056g H20/31.9988g O2 this way the O2 cancels out and you are left with just the H2O so your raw answer would be 36.0319112, then if your instructor requires a significant figure answer that would be to 2 significant figures the information you were given 32g O2, so as above 36g or Water are produced. Just a different way to view and solve the problem with the balanced equation so you can see the way everything relates to everything else. the molar masses of O2 and H2O are simply found my adding up 2 Oxygens 15.9994g x2 = 31.9988g and H2O = 2(1.00794) + 15.9994 = 18.01258 but you then have to multiply that by 2 because the reaction states you get 2 mols in the reaction so that is where I came up with the 36.03056g for the solution. Hope this helps. Dimensional Analysis is and can be one of the best ways to solve these problems, because not always are you going to be dealing with 1:2 ratios.

The unit of f''(a) is milliliters/minute^2

The function t=f(a) models the time, in minutes, for a chemical reaction to occur as a function of the amount a of catalyst used, measured in milliliters.

So, here double differentiation is to be done.

t=f(a)

differentiating with respect to t,

d(t)/dt = d(f'(a))/dt

or, d(f'(a))/dt = 1

again differentiating with respect to t,

d [d(f'(a))/dt]/dt = d(1)/dt = 0 ...1

or, f''(a) = 0

so, here if we put 'unit expression' in Left hand side of 1

it is d [d(f'(a))/dt]/dt  i.e.  mililiters/miniute/minute [as given t is measured in minute and f(a) is measured in ml)

The student collected data on the mass of each artificial cell. The student predicted that the cell in the beaker with 25% sugar solution would have the greatest change in mass after 24 hours. The student's prediction would be correct.

The artificial cell placed in the beaker with 25% sugar solution would likely have the greatest change in mass after 24 hours because of osmosis.

Osmosis is the movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration. In this case, the artificial cell has a semi-permeable membrane that allows water to pass through, but not sugar.

The 25% sugar solution in the beaker is less concentrated than the sugar solution inside the artificial cell, so water will move from the beaker into the cell, causing the cell to swell and increase in mass.

On the other hand, the artificial cells in the beakers with 0% and 12.5% sugar solutions will have less of a change in mass as the solution outside of the cell is more concentrated than inside the cell.

The simplest formula for a compound is made up of 1.677 grams of iron and 0.640 grams of oxygen would be FeO.

What the question is asking here is the empirical formula of an oxide of iron made up of 1.677 grams of iron and 0.640 grams of oxygen. The empirical formula shows the formula in the simplest whole-number ratio of the atoms.

Iron (Fe) = 1.677 grams

Oxygen (O) = 0.640 grams

Converting the masses to moles:

Fe = 1.677/56 = 0.0299 mol

O = 0.640/16 = 0.0400 mol

Now, let's divide by the smallest mole:

Fe = 0.0299/0.0299 = 1.0

O = 0.0400/0.0299 = 1.3

Thus, the empirical formula of the oxide of iron is FeO.

Newton's law of motion that act upon the vehicles at the point of impact is the second law of motion.

Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum that is produced. Mathematically, we have;

F = m·v - m·u/Δt

Where;

m = The mass of the object

v = The final velocity of the object

u = The initial velocity of the object

Δt = The duration of motion of the object during change in velocity

Therefore, given that the mass, 'M', of the truck is larger than the mass, 'm', of the minivan, where the time of change in velocity Δt, and the initial and final velocities of both automobiles are the same such as in a sudden stop, the garbage ruck will exert more force than the minivan, and therefore, the garbage truck has a greater initial momentum before the automobiles are brought to a stop.
