NH4(CO3)

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:

4) Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change.

Explanation:

Mixtures contain different substances with different physical properties, such as boiling point, melting point, solubility, density, and so on. These properties can be used to separate the individual substances in the mixture through various techniques. For example, distillation is a separation technique that relies on differences in boiling points of the substances in a mixture. When a mixture is heated, the substance with the lower boiling point will vaporize first, and it can be collected and cooled to form a pure substance. Similarly, other techniques such as chromatography, filtration, and crystallization also rely on differences in physical properties to separate mixtures.

On the other hand, chemical changes involve the rearrangement of atoms within a substance, resulting in the formation of a new substance with different properties than the original. While chemical changes can be used to synthesize new substances, they are not typically used to separate mixtures.

Answer:

D. in wavelength and temperature!

Explanation:

The energy has been the strength and the viability of the substance and has been measured as wavelength and temperature.

Energy can be defined as the ability of the substance to perform work. The work done has the unit of measurement Joule.

The energy has been the representation of the randomness and the physical and mental system of the substance.

Thus, the temperature has been the measure of the amount of physical energy and the wavelength as the energy of the radiations.

Thus, the energy can be best measured with wavelength and temperature. Hence, option D is correct.

Answer:

stimulus is anything that can trigger a physical or behavioral change. The plural of stimulus is stimuli. Stimuli can be external or internal. An example of external stimuli is your body responding to a medicine. An example of internal stimuli is your vital signs changing due to a change in the body.

Answer: The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

Explanation:

Force is defined as the product of object's mass and acceleration.

Mathematically,

F = ma     ......(1)

or,

a = F/m      .....(2)

where,

F = Force exerted on an object = 60N

m = mass of an object = 30kg

a = acceleration of the object = ?

Putting values in above equation, we get:

a = 60 kg.m/s^2/30 kg = 2m/s^2

The acceleration of the car is 2m/s^2.

From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.

And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.

Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

A net force of 60 N north acts on an object with a mass of 30 kg , so according to Newton's second law of motion the acceleration of the object would be 2 m / s²,the amount of acceleration would decrease if the mass of the object increases.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

F =m × a

As given in the problem, a net force of 60 N north acts on an object with a mass of 30 kg.

60 = 30 × acceleration

acceleration = 60 / 30

                     = 2 m / s²

Thus, the acceleration of the object would be 2 m / s² , and the acceleration would decrease if the mass of the object increases.

Answer: No. The ball wil not bouce back to you. A ball is similar to how light behaves because when you bounce a ball, it will go in a straight line and when it hits something, it will bouse again and go somewhere else. This is also how light behaves.

Explanation:

The ball will not bounce back to you. It will bounce again but go somewhere else similar to the way light behaves.

When a beam of light travels through a medium, it hits the particles in them.  Some of the light rays get absorbed while a few rays get scattered in various directions. The intensity of the scattered light depends on the size of the particle and its wavelength.

When light reaches matter, it can be refracted, reflected, absorbed, or scattered. Light travels in the same direction after hitting the surface is reflected light since the surface is smooth but never follows the same path.

Scattering happens when light bounces off an object or particle in a variety of directions. A ball shows behavior as light. When you bounce a ball, it follows a straight path and hits something, it will bounce again but in a different direction. That is how the light behaves.

Answer:CH4(g) + 2O2(g) →2H2O(l) + CO2(g)

Explanation: CH4 is dioxide and water. So basically whats happening here is that CH4 is being burned down

Since hydrocarbon fuels only contain two elements, we always obtain the same two products when they burn.

Answer:

CH4(g) + 2O2(g) →2H2O(l) + CO2(g)

and it is the chemical reaction that makes it yellow

Explanation:

its obvious

Answer: It may seem as though burning destroys matter, but the same amount, or mass, of matter still exists after a campfire as before. Look at the sketch in Figure below. It shows that when wood burns, it combines with oxygen and changes not only to ashes but also to carbon dioxide and water vapor.
