A sample of aluminum metal absorbs 8.32 J of heat, upon which the temperature of the sample increases from 23.2 degrees C to 30.5 degrees C. Since the specific heat capacity of aluminum is 0.90 J/g-K, the mass of the sample is what in grams?

Answers

Answer 1
Answer:

Given:

8.32 J of heat

from 23.2 degrees C to 30.5 degrees C

heat capacity of aluminum is 0.90 J/g-K

 

Required:

m in grams

 

Solution:

H = mCpT

(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K

m = 1.27g

Identify the elements and the number of atoms of each element in BO2

Answers

The B stands for Boron which is 5 on the periodic table.
The O stands for Oxygen which is 8 on the periodic table.

There is 1 Boron,        It's only 1 because there is only on B which doesn't have coefficent 
There is 2 Oxygen,     The 2 is from the 2 next to the O

A fundamental object that is difficult to divide into smaller bits is known as an element. An element is a substance that cannot be broken down by non-nuclear reactions in chemistry and physics. The elements are boron and oxygen, and their numbers are 1 and 2.

A pure material known as an element is made up of just one type of atom and cannot be divided into two or more different substances. A compound is a pure substance that is created when two or more substances are mixed in a specific mass ratio.

Chemistry's fundamental building block is an atom. It is the smallest fraction of matter into which electrically charged particles cannot be released. It is also the smallest piece of substance with chemical element-like characteristics.

“The element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. Its melting point is 1910 degrees Celsius.” Which correctly evaluates the statement? not reliable because opinions are presented, reliable because testable facts are presented, not reliable because it is very brief ,reliable because metric units are used

Answers

I think the correct answer is the second option. The statement pertaining to the properties of the element vanadium is reliable because the facts presented are testable or can be verified by doing experimentation. Also, nowadays, many studies are present that contains properties of almost anything.

Answer:

B: reliable because testable facts are presented

Habitat ____________ splits ecosystems into pieces and makes populations more vulnerable to disturbances or climate change.A) diversification
B) extinction
C) fragmentation
D) unification

Answers

The correct answer is (C) fragmentation.

Habitat fragmentation is discontinuities in a organism's preferred ecosystem, causing disturbance in a population and ecosystem decay. Cause of fragmentation is geological processes and human activities like deforestation.  Habitat loss, which occur through the process of habitat fragmentation, is considered a greatest to species and biodiversity.

example best shows that the chemistry of water is helpful to plants? Water’s polarity produces a high density, which allows water to move to the leaves. Water’s bent shape causes a slow passage of nutrients up to the leaves of plants. Water’s polarity causes cohesion that pulls other water molecules up through a plant. Water’s bent shape reduces its own passage through the cell membranes of roots.

Answers

The right answer for the question that is being asked and shown above is that: "Water’s polarity produces a high density, which allows water to move to the leaves." Example best shows that the chemistry of water is helpful to plants is that Water’s polarity produces a high density, which allows water to move to the leaves.

Answer:   Water’s polarity causes cohesion that pulls other water molecules up through a plant.
