A substance is a good conductor of electricity. Which of the following best explains the probable position of the substance in t

Mariana [72]

Answer: Option (A) is the correct answer.

Explanation:

Elements present in group 1 are known as alkali metals. Whereas elements present in group 2 are called alkaline earth metals and elements from group 11 to 12 are transition metals.

As it is known that metals have the ability to lose electrons in order to attain stability and electricity is the flow of electrons from one point to another.

Therefore, metals are good conductors of heat and electricity.

Thus, we can conclude that the statement it’s between groups 1 to 12 because it is metal best explains the probable position of the substance in the periodic table.

How much heat will be absorbed by a 26.3 g piece of aluminum (specific heat = 0.930 J/g･°C) as it changes temperature from 23.0°

kotykmax [81]

Answer:

$\boxed {\boxed {\sf 1076.196 \ Joules}}$

Explanation:

Since we are given the mass, specific heat, and temperature, we should use the following formula for heat energy.

$q=mc\Delta T$

The mass of the aluminum is 26.3 grams. Its specific heat is 0.930 Joules per gram degree Celsius. We need to find the change in temperature.

The change in temperature is the difference between the initial temperature to the final temperature.
The temperature changes <em>from</em> 23.0°C <em>to</em> 67.0°C, so the initial is 23 degrees and the final is 67 degrees.
ΔT= final temperature - initial temperature
ΔT= 67°C - 23°C
ΔT= 44°C

Now we know all the values.

m= 26.3 g
c= 0.930 J/g °C
ΔT= 44°C

Substitute the values into the formula.

$q= (26.3 \ g}) \times (0.930 \ J/g \textdegree C) \times (44 \textdegree C)$

Multiply the first two numbers together. The units of grams cancel.

$q= 24.459 \ J/ \textdegree C \times 44 \textdegree C$

Multiply again. This time, the units of degrees Celsius cancel.

$q=1076.196 \ J$

<u>1076.196 Joules</u> of heat will be absorbed by the piece of aluminum.

Which of the following is not a part of the ideas john dalton proposed in his model

NNADVOKAT [17]

The following which is not a part of Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

<h3>What is Dalton atomic theory?</h3>

Dalton has proposed his theory in three parts and each part stated that

The first portion of his theory asserts that all stuff is made up of indivisible atoms.

According to the second section of the theory, all atoms of a given element have the same mass and characteristics.

Compounds, according to the third section, are combinations of two or more different types of atoms.

Dalton has given three laws

Law of conservation of mass
Law of definite proportion
Law of multiple proportion

Thus, the following which is not a part of Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.
