All matter hass mass and volume. Mass is a general property of matter that is the amount of matter it an object. In other words, it is the amount of “stuff” there is.<span>  </span>It is easy to confuse the terms “mass” with “weight” but they are fundamentally different properties. Volume describes how much space matter occupies.<span>  </span>It is not how much “stuff” there is, though that definition is a common mistake that students make.<span>  </span><span>The amount of space that an object takes up is the object’s volume.</span>

How does a conjugate acid differ from its conjugate base?
inna [77]

The conjugate acid is differ from its conjugate base as, conjugate acid is formed by strong base whereas conjugate base is formed by strong acid.

conjugate base is differ from conjugate acids by the presence of the proton. The conjugate acid is formed when proton is added to the bases whereas conjugate bases is formed when proton is released by the acids.

Example of corrugate acids are given below.

NH_{3} → NH_{2} ^{-} +H^{+}

In the above example  NH_{2} ^{-} is conjugate acids.

What is the mass in 0.25 mol of SO2
gulaghasi [49]

0.25 mols SO₂ x 64.058 g SO₂/ 1 mol SO₂ = 16.0145 g SO₂

molar mass of SO₂: 64.058 g

answer: 16 grams of SO₂ (2 sig figs)

check the question to see if its asked for a specific unit for mass (grams or kilograms, if they asked for kiligrams then convert 16 grams to kilograms by dividing it by 1000)

This is the question pls help me
Kryger [21]

Answer:  B

Explanation:  Graph B compares the two temperatures on separate lines so that we can see the comoparison directly, as a function of time.  Not only does the graph quickly answer which condition id most favorable to colony growth, but it also hints at some behaviors that may accelerate growth as time goes on.  Graph C is a possible answer, if the <u>only</u> question is which promotes growth the fastest.   But the questions asks "compare," which Graph B does not allow as well as Graph C.

Consider a bent molecule, such as H2Se, in which the central atom has two lone pairs of electrons. The electronegativities of H
Shalnov [3]

Answer:

Based on these values and on consideration of molecular geometry, the H-Se bond can be considered almost _____non-polar___ and the molecule is __polar_____.

Explanation:

Looking at the difference in electro negativity of the two elements; hydrogen and selenium, one may be led to the conclusion that the molecule is nonpolar since the magnitude of electronegative between the two bonding atoms is minimal.

However, electro negativity difference alone is insufficient to determine the polarity of a molecule. The structure of the molecule is also considered. Based on the structure of the molecule, it is expected to have a dipole moment. Hence the molecule is polar.
