Velocity is a vector quantity that describes the rate and direction of an object's motion.

a) The velocity of the fluid:

V = 35 gpm / (π * (1.05 in)^2 / 4) = 7.09 ft/s

b) Reynolds number:

Re = (62.3 lbm/ft^3 * 7.09 ft/s * 1.05 in) / (1.2 cP) = 4,211.9

[2]- a) Expression to find pressure of methane gas at point B:

PB = PA + rgh

b) Pressure of methane gas at point B:

PB = 1,000 psig + (0.072 lbm/ft^3 * 32.2 ft * 0.0689 psia/ft) = 1,233.5 psig

c) Pressure of oil at point C:

PC = PB - 0.433 psia/ft * 32.2 ft = 1,093.3 psig

[3]- Expression to find pressure of inlet water Pw needed to displace oil:

Pw = PC + (σ / r) * (h2 - h1)

Pw = 1,093.3 psig + (σ / 0.072 lbm/ft^3) * (32.2 ft - 0 ft) = 1,093.3 psig + (σ / 0.072 lbm/ft^3) * 32.2 ft.

What is velocity?

Velocity is a vector quantity that describes the rate and direction of an object's motion. It is commonly represented by the symbol 'v' and is measured in meters per second (m/s). Velocity includes both the speed and the direction of the object. For example, if an object is moving north at 10 m/s, its velocity would be 10 m/s north. Velocity can also be determined by taking the derivative of the position function with respect to time.

A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base, in relatively equal and "large" quantities. Calculations are based on the equation for the ionization of the weak acid in water forming the hydronium ion and the conjugate base of the acid. "HA" represents any weak acid and "A-" represents the conjugate base.

HA(aq) + H2O(l) --> H3O+(aq) + A-(aq)

Ka = [H3O+][A-]

Answer:

234

Explanation:

From the question given above, the following data were obtained:

Alpha particle => ⁴₂He

²³⁸₉₂U —> ? + ⁴₂He

Let the unknown be ⁿₓZ. Thus, the equation becomes

²³⁸₉₂U —> ⁿₓZ + ⁴₂He

Next, we shall determine x, y and Z. This can be obtained as follow:

92 = x + 2

Collect like terms

92 – 2 = x

90 = x

x = 90

238 = n + 4

Collect like terms

238 – 4 = n

234 = n

n = 234

ⁿₓZ => ²³⁴₉₀Z => ²³⁴₉₀Th

Thus the balanced equation

²³⁸₉₂U —> ²³⁴₉₀Th + ⁴₂He

Therefore, the atomic mass of the first element is 234

Answer:

The ideal gas law is a formula that relates the pressure, volume, temperature, and number of moles of a gas. It can be expressed as:

PV = nRT

where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the gas constant, and T is the temperature in Kelvin.

Since the number of moles and the temperature are constant in this problem, we can rearrange the formula to solve for the pressure:

P = (nRT) / V

Plugging in the known values, we get:

P = (nRT) / V

= (n * R * (35 + 273)) / 0.25 L

= (n * R * 308 K) / 0.25 L

We are given that the pressure is 500 mmHg and the volume is 0.25 L at this pressure, so we can set these equal:

500 mmHg = (n * R * 308 K) / 0.25 L

Solving for n, we get:

n = (500 mmHg * 0.25 L) / (R * 308 K)

We know that the pressure and volume of the gas at its original state are what we are trying to solve for. Let's call the original pressure P_0 and the original volume V_0. We can then express the relationship between the original and final state of the gas as:

P_0 * V_0 = n * R * T

Substituting the expression we found for n and the known values, we get:

P_0 * V_0 = ((500 mmHg * 0.25 L) / (R * 308 K)) * R * 308 K

Solving for P_0, we get:

P_0 = (500 mmHg * 0.25 L) / (R * 308 K) * (R * 308 K) / V_0

= (500 mmHg * 0.25 L) / (V_0)

Since V_0 = 0.5 L, we can substitute this value to get:

P_0 = (500 mmHg * 0.25 L) / (0.5 L)

= 500 mmHg / 2

= 250 mmHg

Therefore, the original pressure of the gas was 250 mmHg.

Answer: There are [tex]5.42 \times 10^{23}[/tex] [tex]Ca^{2+}[/tex] ions present in 0.9 mol of [tex]CaCl_{2}[/tex].

Explanation:

According to the mole concept, there are [tex]6.022 \times 10^{23}[/tex] atoms present in one mole of a substance.

As here, 0.9 mol of [tex]CaCl_{2}[/tex] are present. Also, there is only one atom of Ca is present in a molecule of [tex]CaCl_{2}[/tex].

Hence, calcium ions present in 0.9 mol of [tex]CaCl_{2}[/tex] are calculated as follows.

[tex]No. of ions = 1 \times 0.9 \times 6.022 \times 10^{23}\\= 5.42 \times 10^{23}[/tex]

Thus, we can conclude that there are [tex]5.42 \times 10^{23}[/tex] [tex]Ca^{2+}[/tex] ions present in 0.9 mol of [tex]CaCl_{2}[/tex].

Answer:

the answer to this is 71.0 grams of chlorine

Answer:

70.0 %

Explanation:

Step 1: Given data

Step 2: Calculate the mass of oxygen (mO) in the compound

The mass of the compound is equal to the sum of the masses of the elements that form it.

mNxOy = mN + mO

mO = mNxOy - mN

mO = 250 g - 74.66 g = 175 g

Step 3: Determine the percent composition of oxygen in the sample

We will use the following expression.

%O = mO / mNxOy × 100%

%O = 175 g / 250 g × 100% = 70.0 %

The mass of an atom of element Z is 4 amu. This can be determined by subtracting the mass of an atom of carbon (12 amu) and an atom of oxygen (16 amu) from double the mass of an atom of oxygen (32 amu). 32 amu - 12 amu - 16 amu = 4 amu.

An atom of carbon is a basic building block of all organic materials. It is the 6th element in the periodic table and has an atomic number of 6. Carbon atoms have 6 protons and 6 neutrons, and have a valence of 4. This means that carbon atoms can form four bonds with other atoms. Carbon is the basis of all life on Earth, as it is essential for the formation of proteins, fatty acids, and other molecules necessary for life. Carbon atoms have the ability to form a wide variety of molecules with different properties, which makes them highly versatile and important in many different fields, such as medicine and engineering.

Explanation:

The computation of the volume of the elevation is given below:

Here we assume the volume of the elevation be x

As we know that

V¹ ÷ T¹ = V² ÷ T²

Here

V^1 = 1500

T^1 = 290

V^2 = x

T^2 = 210

Now place these values to the above formula

So,  

1500 ÷ 290 = x ÷ 210

x = 1086.2 L

Lewis dot structure of any compound tells about the bonding and outermost electrons present in all the entities present in that compound.

Radon is a noble gas atom and have stable electronic configuration, but still they form radon flouride products due to the high electronegativity of flourine it attracts the lone pair of electrons of radon.

For the formation of compound promotion of 1, 2 or 3 electrons from the 6p orbital to the vaccant 6d orbitals will give rise to 2, 4 or half filled orbitals so they will form only products with odd number of atoms.
