It takes 12. 5 ml of a 0. 30 m hcl solution to neutralize 285 ml of naoh solution. What is the concentration of the naoh solution?
Answer: M₂ = 0
Explanation:
HCl + NaOH — NaCl + H2O
For acid base titrations:
M₁ V₁ = M₂ V₂where lower-script 1 and 2 are the molarity and volume for acid and base respectively.
M₁ = 0.30 M
V₁ = 12.5 ml
M₂ = (unknown)
V₂ = 285
0.30 x 12.5 = 285 M₂
M₂ = 3.8/ 285
M₂ = 0
p.s I think there is an error with the typed question. It’s not possible to use 285 ml of base against 12.5 ml of acid.

What is Public policy?Governmental bodies create laws, set policies, and distribute funds in every society. A system of rules, regulations, courses of action, and financial priorities involving a specific subject that have been established by a governmental body or its representatives is known as public policy.
People and organizations frequently make an effort to influence public policy through advocacy, education, or the mobilization of interest groups.
In Western-style democracies, public policy is clearly shaped differently from how it is in other systems of government. But it is logical to suppose that competing interest groups would always make an effort to sway policymakers in their direction.
Therefore, Public policy begins with identifying an issue. Then, government officials form a solution. and Finally, a government agency implements the solution.

A spring gun shoots out a plastic ball at speed v0. The spring is then compressed twice the distance it was on the first shot
Based on the compression of the spring and the speed, the following are true:
The factor by which the spring's potential energy is increased is = 4.The factor of increase in speed = 2.What is the factor of increase in potential energy?Potential energy is found as:
= 0.5k x (2 x compression²)
= 4 x 1/2kx²
The 4 shows that the potential energy increases by 4 times.
What is the factor of increase in speed?Initial speed is:
= x × √(k/m)
New speed will be:
= Compression factor x speed
= 2x × √(k/m)
The speed will therefore be increased by a factor of 2.

This theory of emotion suggests that first a specific physiological response to stimuli is experienced, and the emotion that results is an interpretation of this unique physiological "code"
James–Lange theory is a physiological theory of emotion that explains that emotions are created in response to experiences and stimuli, where the autonomic nervous system creates physiological responses.
What is James–Lange theory?It is a theory proposed independently by William James and Carl Lange, which suggests that emotions occur as a consequence of physiological reactions to events.
For this theory, emotions are processes that involve a series of triggering conditions or relevant stimuli.
Therefore, we can conclude that the James–Lange theory explains the origin of the components of emotion and where physiological activation plays an important role in the existence of an emotional response.

When a cat drops from a tree to the ground the conversion of gravitational potential energy to Kinetic energy takes place.
After eating its prey the conversion of Chemical to mechanical energy takes place.
Energy conversionEnergy is neither created nor destroyed rather it is transformed/converted from one form to another. when the cat is at rest on the tree it possesses a potential energy but at it falls to the ground the potential energy is converted to a kinetic energy. Also
As the cat consumes the rat the energy absorbed from the consumption of the rat is converted to mechanical energy which enables the mobility of the rat.
Hence we can conclude that the conversion of energy is as listed above.

Charlie earns an annual salary of $61,870. If he is paid weekly, how much would his gross pay be each week?
In a year, there are total 52 weeks usually, so annual salary is weekly salary times 52. Charles' weekly pay is given by: Option d: $1,189.81
How to count the number of ways in a year?
A year contains approx 365 days usually (leaving leap years)
A week contains 7 days.
Dividing 365 in group of 7s, we get:
(1 as remainder, 52 as quotient), so one day is left only) (this is not always the case that there would be 52 weeks only, there can be sometimes 51 weeks due to some incomplete weeks).
(for general case, we will assume there are 52 weeks in an year).
For the considered case, it is specified that:
Annual salary of Charles = $61,870
There are 52 weeks in an year, so, dividing his salary in 52 parts, we get his weekly salary as:
Thus, Charles' weekly pay is given by: Option d: $1,189.81
