The question is incomplete as the mass of copper is also needed to solve this. The given mass of copper is 0.9075 g.

The volume of 6.0 M sodium hydroxide(NaOH) required to fully react with copper nitrate produced is 4.76 ml.

The reaction between copper(Cu) and nitric acid(HNO3) is as follows:

Cu + HNO3 = Cu(NO3)2

According to the above reaction

1 mole of copper produces 1 mole of copper nitrate

Or 63.5 g of copper produces 1 mole of copper nitrate

Thus, 0.9075 g of copper produces 1/63.5 x 0.9075 = 0.0143 moles of copper nitrate

The reaction between sodium hydroxide(NaOH) and copper nitrate {Cu(NO3)2} is as follows:

2NaOH + Cu(NO₃)₂ ---> 2NaNO₃ + Cu(OH)₂

From the above equation,

1 mole of copper nitrate fully reacts with 2 moles of sodium hydroxide

Thus, 0.143 moles of copper nitrate fully reacts with 2 x 0.143 = 0.286 moles of sodium hydroxide

The molarity of the given  NaOH solution is 6 M.

Hence its volume would be

Molarity = No. Of moles/Volume of solution(in liters)

6 = 0.286/ Volume

Volume = 0.0476 liters or 47.6 ml.

Hence, the volume of 6.0 M sodium hydroxide(NaOH) required to fully react with the copper nitrate produced is 4.76 ml.

The blurring effects of the Earth's atmosphere would decide the smallest angular size that this telescope could resolve.

The term "angular size" refers to an object's apparent size as seen from an observer on Earth. The least angular size can be affected by the magnitude of lights received by telescopes, which can be changed by the earth's hazy atmosphere. Telescopes collect and amplify light from distant objects. Earth's atmosphere substantially limits astronomical observations for two basic reasons.

First, not all atmospheric wavelengths are equally transparent, and some wavelength regimes are completely out of range for ground-based telescopes. Therefore, while developing a telescope with a specific angular size, the earth's atmosphere must be considered.

A. They consist of one or more atoms bonded together.

Explanation:

40.1L volume of h2 gas that is measured at 26 c and 100 kpa will be produced from Na of mass given as 3.25g.

Kilopascal (kPa), a 1,000-fold increase in the meter-kilogram-second system’s measure of pressure and tension (the International System of Units [SI]).

Blaise Pascal, a French mathematician and scientist, is honored by its name.

The formula below can be used to translate kg/cm2 into kPa:

A kPa equals 1000 pascals (Pa)

1 kg/cm2 is equal to 98066.5 pascals (Pa), or kPa value multiplied by 1000 Pa.

Thereafter,

T = 26°C

= 299K

P = 100kPa

P= 100/101.325

=0.986923 atm

mass = 3.25g

Atomic mas of H = 1.00784

molar mass of H2 gas = 2x10.00784

= 2.01568g/mol

mole of H2 in 3.25g = 3.25/2.01568 = 1.612359 mol

This gas provided in the question follows the ideal gas equation, so it can be written as

PV = nRT

⇒ V = nRT/P

= (1.612359x 0.0821x 299) / 0.986929

⇒ V = 40.104473

V = 40.1 L

Thus, the volume of gas was found to be 40.1Liter.

Answer:

I don't have the full details so... Position 1 + Position 2

That's if "0" doesn't count as a position.

Explanation:

"What was the distance traveled" is basically "how much did you travel?"

e.g. Position 1 was 12 miles, and Position 2 was 7. 12 + 7 = 19.

(a) The new speed of the aircraft with respect to the ground is 1,539.13 mph.

(b) The direction of the aircraft is 7⁰ north east.

The new speed of the air craft is the resultant speed of the aircraft and it is calculated as follows;

R² = A² + B² - 2AB cos(R)

where;

A = 701 mph + 848 cos(13)

A = 1,527.266 mph

B = 848 x sin(13)

B = 190.76 mph

R = √(A² + B²)

R = √[(1,527.66²) + (190.76²)]

R = 1,539.13 mph

θ = arc tan (y/x) = arc tan (B/A)

θ = arc tan (190.76/1527.66)

Nuclear fusion can release large amounts of energy is the True statement.

The nuclear fusion reaction occurs when two or more atom combine together to form a heavier atom. For example, when two hydrogen atoms fuse to form one helium atom.

This is the same process that powers the sun and creates huge amounts of energy several times greater than fission. It also doesn't produce highly radioactive fission products.

The nuclear fusion reaction releases large amount of energy, because Fusion reactions have an energy density many times greater than nuclear fission.

The thickness of an anti-reflective coating is 96 nm.

Define Wavelength?

The wavelength in waves is defined as the distance between the crests and troughs. It can be calculated in the meter in the SI system. The crest is the upper part of the wave, and the trough is the lower part.

Given that,

The index of the anti-reflective coating is n = 1.3

The wavelength is denoted as  λ = 500 nm = 500×[tex]10^{-9}[/tex]m

The expression for interference can be written as

2t = (m+½)λf

m=0 is the minimum reflection order.

λf is referred to as the wavelength of the film.

By substituting the values in the above expression we get,

2t = (m+½)λf

2t = (0+½)λf

t = λf/4 (this will noted as equation 1 for more clarity )

The wavelength of the light in a medium with refractive index can be expressed as

λf = λ/n

By substituting the values in equation1 we get,

t = λf/4

t = (λ/n)/4

t = λ/4n = 500/(4×1.3) = 96 nm.

Therefore , the thickness of an anti-reflective coating is 96nm.

Manhattan distance is a popular heuristic function for sliding-tile puzzles. It is calculated by tallying the number of moves along the grid that each tile takes to move away from its intended position. The obvious option for a heuristic function is the Euclidean (straight-line) distance, which, as far as we are aware, can never underestimate the distance but might do so if there is a target obstacle to avoid on the way there.

The effect after the current is tripled is changing the drift velocity by a factor 3.

We need to know about drift velocity of electrons to solve this problem. The drift velocity can be determined as

v = I / (n . A . q)

where v is drift velocity, I is current, n is atom number density, A is surface area and q is the charge.

From the question above, we know that

I2 = 3 . I1

According to drift velocity formula, the drift velocity is proportional to current

v ~ I

Hence, the ratio of drift velocity and current is

v1 / v2 = I1 / I2

The explanation on how the rudders turn the boat​ is by redirecting the fluid  which results in an opposite force aiding the motion of the boat.

This law was coined by Isaac Newton and it states that when object X exerts a force on another object Y, the object Y must exert a form of counter force which has the same magnitude but opposite in direction.

In the case of the rudder, it redirects the fluid which then exerts an equal force of the same magnitude and an opposite direction. This thereby results in the motion of the boat and is therefore the most appropriate choice.

The temperature of a 1.59l flask containing 0.175mol of Ne at a pressure of 1.09atm is 120.70 K.

How do you find the temperature of the compound?

We know that the ideal gas law uses the formula:

PV = nRT

where,

P is referred as the pressure, which is measured in atmospheres (atm),

V is referred as the volume, which is measured in cubic meter ([tex]m^{3}[/tex]),

T  is referred as the temperature, which is measured in kelvin (K),

R  is referred as the ideal gas law constant , i.e., 0.0821 atm(L)/mol(K),

n is known as the number of moles (mol).

Given that,

P = 1 atm = 101 325 Pa

  1.09 atm = 1.09 atm x 101 325 Pa/atm = 110 444 Pa

n = 0.175 mol

V = 1.59 x 10⁻³ m³
