Answer:
0,1276 M
Explanation:
Molair mass of NaOCl = 74,44 g/mol
You have 9,5 g/L.
You need to calculate with the molair mass, how many moles 9,5 g are:
9,5 g / 74,44 g/mol = 0,1276 mol
0,1276 mol / 1 L = 0,1276 M
The molarity of a bleach solution containing 9.5 g of NaOCL per liter of bleach is mathematically given as
M= 0.1276 M
What is the molarity of a bleach solution containing 9.5 g of NaOCL per liter of bleach?Generally, the equation for the Molar mass is mathematically given as
M=m/(g/mol)
Therefore
M=9,5 g / 74,44 g/mol
M= 0,1276 mol
Hence
M= 0.1276 M
In conclusion, the molarity
M= 0.1276 M

Newton's first law is demonstrated in what station?
Answer:
hope this helps!
Explanation:
This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it. Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop.

Which of the following would happen if Earth's moon were half the size that it is now? O The oceans' tidal variations would be smaller because the Moon would exert less gravitational pull on Earth's oceans. O The oceans' tidal variations would be greater because the Moon would exert less gravitational pull on Earth's oceans. O The oceans' tidal variations would be greater because the Moon would exert more gravitational pull on Earth's oceans. The oceans' tidal variations would be smaller because the Moon would exert more gravitational pull on Earth's oceans. & Previous

What is the purpose of a catalyst?
Answer:
option c
Explanation:
as catalyst increases the reaction while activation energy is inversely proportional to rate of reaction, so option c is correct
The purpose of a catalyst to lower the activation energy of a reaction.
What is catalyst?A type of chemical that, without becoming consumed by the process, speeding a chemical reaction or reduce the temperature as well as the pressure required to initiate one. The addition of a catalyst to speed up a reaction is known as catalysis.
What is activation energy?The bare minimum additional energy needed by a reactive molecule to transform into a product is considered as activation energy.
The purpose of a catalyst is to lower the activation energy of a reaction.
Therefore, the correct answer will be an option (C).

Describe an every day example of an object that has energy of motion and object that has stored energy
Answer:
Humans
Explanation:
Humans have energy of motion and store energy.
Every object will have any form of energy. For instance, when we are walking we gains a kinetic energy. We use electronic devices where electrical energy is stored and can be converted to mechanical energy to activate any motors.
What is energy transformation?Energy can neither be created nor be destroyed. However it can be transformed to any other forms. Thus, the total energy will conserved always.
We have a lot of example for energy transformation and storage. The energy form stored by virtue of the position of an object is called potential energy. Whereas, when the object starts moving potential energy converts to kinetic energy.
Thus, thermal vibrations of particles, our every day activities all are associated with a kinetic energy. Kinetic energy of each body depends on the mass and velocity of the body. The more the mass and velocity more will be the kinetic energy.

This is the type of wave that travels in one direction but the energy travels in the opposite direction
Answer:
Transverse wave
Explanation:
A wave is defined as a disturbance along a medium which transfers energy from one point to another.
A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.
In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.

The vapor pressure (in torr) of a 35°C solution : 52 torr
Further explanationGiven
x propanol = 0.75
P°ethanol=100 torr
P°propanol=36 torr
Required
the vapor pressure
Solution
Raoult's Law
P solution = xA.P°A +xB.P°B
x ethanol = 1- 0.75 = 0.25
Input the value :
P solution = 0.25 x 100 + 0.75 x 36
