Explanation:

Calculate the amount of heat, in Joules, needed to raise 34.0g of water from 55.0°C to 76.0*C. The specific heat of water is 4.18 J/gºC.

Answers

Answer:

2984.52J

Explanation:

Using the formula: Q = m × c × ∆T

Where;

Q = amount of heat (in Joules)

m = mass (in grams)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

Based on the information provided in the question;

m = 34.0g

c = 4.18 J/gºC.

Initial temperature = 55.0°C

Final temperature = 76.0°C

Hence, Q = m × c × ∆T

Q = 34 × 4.18 × (76 - 55)

Q = 142.12 × 21

Q = 2984.52J

Therefore, 2984.52J is the amount of heat, in Joules, needed to raise 34.0g of the water.

what is Brownian motion​

Answers

Answer: the erratic random movement of microscopic particles in a fluid, as a result of continuous bombardment from molecules of the surrounding medium. Brownian motion, or pedesis, is the random motion of particles suspended in a medium. This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain. Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for the Scottish botanist Robert Brown, the first to study such fluctuations (1827).

What is chemical change?

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

5.What effect can you create by using a quick shutter speed?

Answers

Answer:

Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.

The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

N-O is the most polar without being considered ionic. Hence, option C is correct.

What is an ionic bond?

An ionic bond is formed by the complete transfer of some electrons from one atom to another.

Bonds between carbon and other elements such as oxygen or nitrogen are polar. The polarity of a bond depends upon the electronegativities of the bonded atoms.

what substance has a mass of 9.5 grams and a volume of 2.1 cm^3?
SUBSTANCE.

Answers

Explanation:

Given parameters:

Mass  = 9.5g

Volume  = 2.1cm³

Unknown:

What kind of substance is this = ?

Solution:

To determine the kind of substance given, we need to find its density from the given parameters.

The density of a substance can tell us about such body.

Density is an intensive property and it is the mass per unit volume.

       Density  = [tex]\frac{mass}{volume}[/tex]

Now insert the parameters and solve;

    Density  = [tex]\frac{9.5}{2.1}[/tex]  = 4.52g/cm³

What is the hydrogen ion concentration in the solution?
A. 0.2 mol/dm3
B. 0.05 mol/dm3
C. 1.00 mol/dm3
D. 2.00 mol/dm3

Answers

Answer:B. 0.05 mol/dm3

Explanation:

The hydrogen ion concentration in the solution is 2 mol/dm³

The correct answer to the question is Option D. 2 mol/dm³

We'll begin by calculating the molarity of the solution.

Volume = 25 cm³ = 25 / 1000 = 0.025 dm3

Mole of H₂SO₄ = 0.025 mol

Molarity of H₂SO₄ =?

Molarity = mole / Volume

Molarity of H₂SO₄ = 0.025 / 0.025

Molarity of H₂SO₄ = 1 mol/dm³

Finally, we shall determine the concentration of Hydrogen ion in the solution.

H₂SO₄(aq) —> 2H⁺(aq) + SO₄²¯(aq)

From the balanced equation above,

1 mole of H₂SO₄ contains 2 moles of H⁺.

Therefore,

1 mol/dm³ H₂SO₄ will also contain 2 mol/dm³ H⁺.

Thus, the concentration of Hydrogen ion in the solution is 2 mol/dm³

The correct answer to the question is Option D. 2 mol/dm³
