Answer:
T2= 7.3°C
Explanation:
To solve this problem we will use Charles law equation i.e,
V1/T1 = V2/T2
Given data
V1 = 269.7 L
T1 = 6.12 °C
V2= 320.4 L
T2=?
Solution:
Now we will put the values in equation
269.7 L / 6.12°C = 320.4 L / T2
T2= 320.4 L × 6.12°C/ 269.7 L
T2= 1960.85 °C. L /269.7 L
T2= 7.3°C
A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical <span>arrangement of polar bonds in a more complex molecule.</span>
Answer:
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
Explanation:
The image depicts the atoms of two different elements; atoms of lighter and heavier elements.
And the rate of diffusion (movement of atoms) of an element is inversely proportional to the square root of its molecular.
⇒ As the weight increases, the rate of diffusion (movement of atoms) decreases.
And as the weight decreases, the rate of diffusion (movement of atoms) increases.
so, heavier atoms move slowly compared to lighter atoms.
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
Answer:
b. reactants are two ionic compounds.
Explanation:
A double-replacement reaction is different from a single-replacement reaction because a double-replacement reaction is a reaction between two ionic compounds while in a single-replacement reaction one atom replace another atom. In addition, the product formed from a double-replacement reaction often precipitate from the given solution.
