Answer:

B. It is highly flammable.

Explanation:

Chemical properties deal with how the substance will behave when brought into contact with other substances, and usually have to do with it undergoing some kind of reaction. Flammability is a chemical property.

Density, melting point, and color are all considered physical properties.

Calculate the specific heat of a piece of wood if 2000 g of wood absorbs 75,250 J of heat, and its temperature changes from 30°C

inna [77]

Answer:

C

Explanation:

The specific heat capacity=quantity of heat in joule/mass×change in temperature

from this question the quantity of heat is 75250,the mass is 2000 and the change in temperature is 50-30

which is 20

therefore

c=75250/2000×20

c=75250/40000

c=1.88

I hope this helps

If gas is initially at 350L and 500k then changes to 295K what is the new volume

Dimas [21]

<h2>Hello!</h2>

The answer is:

The new volume is equal to 206.5 L.

To solve this problem, we need to assume that the pressure is constant, and use the Charle's Law equation, so, solving we have:

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

We are given:

$V_1=350L\\T_1=500K\\T_2=295K$

Then, using the Charle's Law equation, we have:

$\frac{350L}{500K}=\frac{V_2}{295K}$

$\frac{350L}{500K}=\frac{V_2}{295K}\\\\V_2=\frac{350L}{500K}*295K=206.5L$

Hence, we have that the new volume is equal to 206.5 L.

Have a nice day!

Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic:

Zinaida [17]

The electron configuration of V³⁺ is [Ar] $3d^2$ . The ion is paramagnetic because it has two unpaired electrons

<h3>What is paramagnetic?</h3>

A weak magnetic field supplied externally can weakly attract some materials, which then create internal magnetic fields that are directed in the same direction as the applied magnetic field. This phenomenon is known as paramagnetic.
Diamagnetic materials, in contrast, are attracted to magnetic fields and produce induced magnetic fields that are directed in the opposite direction from the applied magnetic field.
The majority of chemical elements and some compounds are considered to be paramagnetic materials.
Paramagnetic materials have a relative magnetic permeability that is somewhat more than 1, which makes them attracted to magnetic fields.
The applied field induces a linearly decreasing magnetic moment that is relatively weak.
Modern experiments on paramagnetic materials are frequently done with a sensitive analytical balance since it typically requires a sensitive analytical balance to identify the effect.
