A chemist is performing a chemical reaction under a fume hood. The chemist has a set of beakers, flasks, and tubes set up under the fume hood, with various liquids being combined inside the glass containers. The fume hood is turned on in order to withdraw any toxic gases and expel them outside the building. Which part of this system is designated as the surroundings?.
The part of the system that is designated as surroundings is;
Inside the fume hood
Thermodynamics SystemsWe are told that the chemist is performing a reaction under a fume hood.
Now, in thermodynamics there is what we call homogenous and heterogenous systems. Each of those systems have what we call surroundings, system and boundary.
Now, everything that is around a system is referred to as a surrounding while boundary is simply defined as everything that is external to the system.
Now, in this case since the chemist is performing the chemical reaction under a fume hood, then the boundary will be everything outside the fume hood while the surroundings will be inside the fume hood.

A worker pushes a box with a horizontal force of 50. 0 n over a level distance of 5. 0 m. If a frictional force of 43 n acts on the box in a direction opposite to that of the worker, what net work is done on the box ?.
Answer:
7N
Explanation:
Since the forces are working in opposite directions, you substract i.e
50.0N - 43N = 7N
A saturated aqueous solution of cdf2 is prepared. The equilibrium in the solution is represented above. In the solution, [cd2+]eq=0. 0585m and [f−]eq=0. 117m. Some 0. 90mnaf is added to the saturated solution. Which of the following identifies the molar solubility of cdf2 in pure water and explains the effect that the addition of naf has on this solubility?.
The option that identifies the molar solubility of CdF₂ in pure water is;
A: The molar solubility of CdF₂ in pure water is 0.0585M, and adding NaF decreases this solubility because the equilibrium shifts to favor the precipitation of some CdF₂.
Understanding Molar SolubilityThe equation of this reaction is;
CdF₂ (s) ⇄ Cd²⁺ (aq) + 2F⁻ (aq)
We are told that;
[Cd²⁺] (eq) = 0.0585m and [F⁻] eq = 0.117m.
Also, we see that 0.90m NaF is added to the saturated solution.
Now, molar solubility is defined as the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
Thus, we can conclude that The molar solubility of CdF₂ in pure water is 0.0585M, and adding NaF decreases this solubility because the equilibrium shifts to favor the precipitation of some CdF₂.

Explanation:
A box is sliding down an incline tilted at an angle 14. 0° above horizontal. The box is sliding down the incline at a speed of 1. 70 m/s. The coefficient of kinetic friction between the box and the incline is 0. 380. How far does the box slide down the incline before coming to rest?.
The net forces on the box acting parallel and perpendicular to the incline, respectively, are
∑ F[para] = mg sin(14.0°) - F[friction] = ma
∑ F[perp] = F[normal] - mg cos(14.0°) = 0
where m = mass of the box and a = its acceleration.
The second equation tells us
F[normal] = mg cos(14.0°)
so that friction has a magnitude of
F[friction] = 0.380 F[normal] = 0.380 mg cos(14.0°)
Solve the first equation for a :
mg sin(14.0°) - 0.380 mg cos(14.0°) = ma
a = g sin(14.0°) - 0.380 g cos(14.0°)
a ≈ -1.24 m/s²
Assuming the box slides down the incline with constant acceleration, solve for ∆x, the distance it slides before coming to rest:
0² - (1.70 m/s)² = 2a ∆x
∆x = -(1.70 m/s)² / (2 (-1.24 m/s²))
∆x ≈ 1.16 m

How many integers between 2022 and 2388 have four distinct digits arranged in an increasing order?.
Answer:
The total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order is 15.
Explanation:
Given :
Numbers -- 2020 and 2400
The following steps can be used in order to determine the total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order:
Step 1 - According to the given data, there are two numbers 2020 and 2400.
Step 2 - So, the integers having four distinct digits arranged in increasing order are:
2345, 2346, 2347, 2348, 2349, 2356, 2357, 2358, 2359, 2367, 2368, 2369, 2378, 2379, and 2389.

131.6 N/C12.6 ° above the negative x–axisHow are the net electric field magnitude and direction calculated?The possible questions based on a similar question posted online are;
(a) The net electric field at the origin.
The electric field due to charge q₁ is given as follows;
[tex]\vec E_{1x} = \mathbf{ \dfrac{1}{4 \cdot \pi \cdot \epsilon_0} \cdot \dfrac{q_1}{\vec{r}^2_2}}[/tex]
Which gives;
[tex]\vec{E}_{1x} =\mathbf{ \dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(-4 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2}} \cdot cos\left(arctan\left(\dfrac{0.8}{0.6} \right) \right) =-21.6 \, N/C[/tex]
[tex]\vec{E}_{1y} = \mathbf{\dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(-4 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2}} \cdot sin\left(arctan\left(\dfrac{0.8}{0.6} \right) \right) = 28.8 \, N/C[/tex]
Which gives;
[tex]\vec{E}_1 = \mathbf{21.6 \, N/C \cdot \hat x + 28.8 \, N/C \hat y}[/tex]
[tex]\vec{E}_{2x} = \dfrac{\left(9 \times 10^9 \, N \cdot m/C^2 \right) \cdot \left(6.00 \, nC \times \dfrac{10^{-9}C}{1 \, nC} \right)}{\left(1 \, m \right)^2} = 150 \, N/C[/tex]
Therefore;
[tex]\vec {E} = \left[ 21.6 \, N/C - 150 \, N/C \right] \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)[/tex]
[tex]\vec {E} = \mathbf{\left( -128.4 \, N/C \right) \left( \hat x \right) + \left(28.8 \, N/C \right) \left( \hat y \right)}[/tex]
The magnitude of the net electric field is therefore;
E = [tex]\sqrt{(-128.4^2 + 28.8^2)}[/tex] ≈ 131.6
The magnitude of the net electric field at the origin is E ≈ 131.6 N/C(b) The direction of the net electric field at the origin.
