Explanation:
Answer:
0.0071g
Explanation:
From the question, we know that the molarity of the BaCl2 is 0.00237M. This means there are 0.00237 moles in 1dm^3 or 1000cm^3 of solution.
We also know that 35ml of the BaCl2 reacted. Here, we need to calculate the number of moles in 35.7ml of BaCl2.
This is calculated as follows;
0.00237moles are in 1000cm^3
Thus x moles will be present in 35ml ( we should note that cm^3 is same as ml)
X = (0.00237 × 35) ÷ 1000 = 0.00008295 moles.
From the reaction equation, we can see that 2 moles of BaCl2 yielded 1 mole of Ba(OH)2.
This means 0.00008295mole of BaCl2 will yield 0.00008295 ÷ 2 = 0.000041475 moles of Ba(OH)2.
To calculate the mass of Ba(OH)2 formed, we simple multiply the number of moles yielded by the molar mass of Ba(OH)2.
Molar mass of Ba(OH)2 = 137 + 2(17)
= 171g/mol
Mass = 171 × 0.000041475 = 0.007092225g

In this classical conditioning example, Michael's anticipatory nausea when entering the treatment room is considered a conditioned response (CR). Therefore option A is correct.
The conditioned response is a learned response that occurs as a result of the pairing of a neutral stimulus with an unconditioned stimulus (US).
Initially, the chemotherapy (US) would have caused the unconditioned response (UR) of nausea and vomiting. However, after multiple treatments, the treatment room (CS) becomes associated with the chemotherapy (US) through repeated pairings.
Eventually, the treatment room alone (CS) can evoke the conditioned response (CR) of anticipatory nausea before Michael even receives the chemotherapy, as his body has learned to anticipate the unpleasant experience based on environmental cues.
Therefore option A is correct.

what is the average rate of change of y = cos (2x) on the interval [0, π2]?
The average rate of change of the function y = cos(2x) over the interval (0, π/2) is [tex] \frac{-4}{\pi}[/tex]
The average rate of change over a given interval is defined thus :
[tex] R = \frac{f(b) - f(a)}{b - a}[/tex] Where a and b are the interval valuesAt a = 0 :
f(0) = cos(2(0)) = Cos 0 = 1At b = π/2 :
f(π/2) = cos(2(π/2)) = Cos π = - 1Hence,
[tex] \frac{f(b) - f(a)}{b - a} = \frac{-1-1)}{\frac{\pi}{2} - 0} = \frac{-2}{\frac{\pi}{2}} = \frac{-4}{\pi} [/tex]
Therefore, the average rate of change over the interval is [tex] \frac{-4}{\pi}[/tex]

let f be the function defined above, where c and d are constants. if f is differentiable at x = 2 what is the value of c + d?
Answer: The values for the constants are c=2, and d=-4.
explanation: We have the function f, defined as:
and
where c and d are constants.
So, if f is differentiable at x=2, then it must be continuos at x=2, therefore
Let's call this, equation 1.
On the other hand, we have that f is differentiable, therefore
and
so, we calculate
which, replacing in equation 1, gives us
Finally, the answer is that c=2, and d=-4.
The constants have the values c=2 and d=-4.
What is constants?A constant is an identifier (name) for a simple value. As the name suggests, that value cannot change during the execution of the script (except for magic constants, which aren't actually constants). Constants are case-sensitive.
A constant in computer programming is a value that should not be changed by the program while it is running normally, i.e., the value is constant.
Although the phrases "constant" and "named constant" are frequently used interchangeably, a constant is said to be "named" when it is connected to an identifier.

Consider the chemical equation. CuCl2 2NaNO3 Right arrow. Cu(NO3)2 2NaCl What is the percent yield of NaCl if 31.0 g of CuCl2 reacts with excess NaNO3 to produce 21.2 g of NaCl? Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100.. 49.7% 58.4% 63.6% 78.7%
Answer:
D. 78.7% on edge 2020
Explanation:
i got 100
The percent yield of NaCl is 78.7 %
CuCl₂ + 2NaNO₃ → Cu(NO₃)₂ + 2NaCl
How NaNO₃ is determined to be in excess?If the NaNO₃ is determined to be in excess, the limiting reagent is the chloride. We convert the mass to moles:
31 g . 1mol / 134.45g = 0.230 moles
Ratio is 1:2, so we can make a rule of three to determine the theoretical yield
1 mol of copper (II) chloride reacts to produce 2 moles of sodium chloride.
Then you can find out how much NaCl 31.0g of CuCl₂ should produce using stoichiometry. Divide 31.0g by the molar mass of CuCl₂ (134.446g/mol) to get 0.2306mol CuCl₂. Than multiply 0.2306mol CuCl₂ by 2 to get 0.4612mol NaCl.
Than multiply 0.4612mol by the molar mass of NaCl (58.45g/mol) to get 26.95g of NaCl.
that means that 100% yield would give you 26.95g of NaCl so to find percent yield divide 21.2 by 26.95 to get 0.7867 which is 78.7% yield
Then, 0.230 moles of CuCl₂ will react to produce (0.230 .2) /1 ) = 0.461 moles of NaCl → we convert the moles to mass → 0.461 mol . 58.45 g / 1mol = 26.9 g
To find percent yield we do → (Yield produced / Theoretical yield) . 100
(21.2 g / 26.9 g) . 100 = 78.7 %

on a test flight a rocket with mass 400 kg blasts off from the surface of the earth. the rocket engines apply a constant upward force f until the rocket reaches a height of 100 m and then they shut off.
Answer:
F= 11.76 kn
Explanation:
The rocket engines apply a constant upward force of 15680 N.
What is force?Force can be said as the amount of pressure that is applied ob an object. One can easily determine the mass and the velocity to find the force that is applied to an object.
Gravitational acceleration which will be represented by g = 9.8 m/s2
Mass of the rocket which will be represented by M = 400 kg
Constant upward force that is applied on the engine of the rocket which will be represented by F
The height through which engines accelerate the upward force upon the rocket will be represented by h = 100 m
Work done by the engine which will be represented by W
W = Fh
Maximum height well above the surface, this data will represent the rocket reaches which will be represented by H
The work completed with the help of the engine on the rocket is equal to the potential energy gained with respect to maximum height.
W = MgH
Fh = MgH
F(100) = (400)*(9.8)*(400)
F = 15680 N
