How Much Hear Must Be Obsorberd By 375.0 Grams Of Water To Raise Its Temperature From 10.0c To 35.0c?

Answers

Answer 1

Answer:

The heat absorbed by water is 39243.75 J.

Explanation:

Given data:

Mass of water = 375.0 g

Heat absorbed by water= ?

Initial temperature = 10.0°C

Final temperature = 35.0 °C

The specific heat capacity of water = 4.186 j/g.°C

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT = 35°C - 10°C

ΔT = 25°C

Q = m.c. ΔT

Q = 375.0 g× 4.186 j/g °C × 25°C

Q = 39243.75 J

The heat absorbed by water is 39243.75 J.

Name and describe the chemical models scientists use to make predictions.

Answers

In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations. Models are a mentally visual way of linking theory with experiment, and they guide research by being simplified representations of an imagined reality that enable predictions to be developed and tested by experiment. Models have a variety of uses – from providing a way of explaining complex data to presenting as a hypothesis. There may be more than one model proposed by scientists to explain or predict what might happen in particular circumstances. Often scientists will argue about the ‘rightness’ of their model, and in the process, the model will evolve or be rejected. Consequently, models are central to the process of knowledge-building in science and demonstrate how science knowledge is tentative.

The isotopes of Madeupium (Ma) and their abundance in nature are shown below. Which is the most likely estimate of what the atomic mass is close to?

Ma-74 (74.333 - 85%)

Ma-75 (74.999 - 10%)

Ma-76 (75.700 - 5%)

A. 74 g

B. 75 g

C. 76 g

Answers

Answer:

A = 74 g

Explanation:

Given data:

Ma-74 (74.333 - 85%)

Ma-75 (74.999 - 10%)

Ma-76 (75.700 - 5%)

Atomic mass close to = ?

Solution:

1st of all we will calculate the average atomic mass.

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass) / 100

Average atomic mass  = (85×74.333)+(10×74.999)+(5×75.700) /100

Average atomic mass =  6318.305 +749.99+ 378.5 / 100

Average atomic mass= 7446.795/ 100

Average atomic mass = 74.467 amu

The average atomic mass is closer to the 74 g.

Answers

Answer:

higher temperature → more kinetic energy → more space between particles higher volume

Explanation:

Kinetic Molecular Theory states that gas particles exhibit perfectly elastic collisions and remain in constant motion. Absolute temperature  is directly proportional to the average kinetic energy of gas particles.

The density of silver is 10.49 g/cm^3. Find the volume of a piece of silver with a mass of 31.5 grams.

Answers

Answer:

The answer is 3.00 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question

mass of metal = 31.5 g

density = 10.49 g/cm³

We have

[tex]density = \frac{31.5}{10.49} \\ = 3.002859866...[/tex]

We have the final answer as

What are the 6 types of chemical reactions?

Answers

Answer:

Explanation:

Six common types of chemical reactions are: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions .

Chemical reactions can be classified into six main types based on their characteristics. The six types of chemical reactions are Combination (Synthesis) Reaction, Decomposition Reaction, Displacement (Single Replacement) Reaction, Double Displacement (Double Replacement) Reaction, Combustion Reaction, and Redox (Oxidation-Reduction) Reaction.

Combination reactions involve the union of two or more substances to form a more complex compound. Decomposition reactions involve the breakdown of a single compound into simpler substances.

Displacement reactions occur when an element displaces another element in a compound, resulting in the formation of a new compound and a different element. Double displacement reactions involve the exchange of ions between two compounds, leading to the formation of two new compounds.

Combustion reactions occur when a substance reacts rapidly with oxygen, producing heat and light. Understanding these different types of chemical reactions helps in predicting and understanding the behavior of substances during chemical transformations.

Therefore, the six types of chemical reactions are Combination (Synthesis) Reaction, Decomposition Reaction, Displacement (Single Replacement) Reaction, Double Displacement (Double Replacement) Reaction, Combustion Reaction, and Redox (Oxidation-Reduction) Reaction.

Silver is a shiny metal that conducts electricity very well . It can be molded into thin sheets it means it can spread into a like a sheet and these type of properties is known as malleability.

Potassium is dull and brittle it means that it can't be change into sheet when you try to change in sheet it will break and these properties are called as brittlness and when it is has been dissolved into water, which it does quite easily. Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting points and boiling points.
