Answer:

You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.

An element with an electronegativity of 0.9 bonds with an element with an electronegativity of 3.1 what phrases best describes t
Ahat [919]

Explanation:

According to the electronegativity table, whenever there a difference of more than 2.0 then the bond formed will be ionic in nature. On the other hand, if electronegativity difference is less than 0.5 then the bond formed will be non-polar covalent in nature.

As it if given that electronegativity difference of given elements will be as follows.

        Electronegativity difference = 3.1 - 0.9

                                                       = 2.2

Since, the electronegativity difference of given elements is 2.2. Hence, these elements will form an ionic bond.

Thus, we can conclude that mostly ionic in character and formed between a metal and non-metal best describes the bond between these elements.

1. Calculate the average reaction rate expressed in moles H2 consumed per liter per second.
valentina_108 [34]

Answer:

1) 0.0025 mol/L.s.

2) 0.0025 mol/L.s.

Explanation:

  • For the reaction:

<em>H₂ + Cl₂ → 2HCl.</em>

<em></em>

<em>The average reaction rate = - Δ[H₂]/Δt = - Δ[Cl₂]/Δt = 1/2 Δ[HCl]/Δt</em>

<em></em>

<em>1. Calculate the average reaction rate expressed in moles H₂ consumed per liter per second.</em>

<em></em>

The average reaction rate expressed in moles H₂ consumed per liter per second = - Δ[H₂]/Δt = - (0.02 M - 0.03 M)/(4.0 s) = 0.0025 mol/L.s.

<em>2. Calculate the average reaction rate expressed in moles CI₂ consumed per liter per second.</em>

<em></em>

The average reaction rate expressed in moles Cl₂ consumed per liter per second = - Δ[Cl₂]/Δt = - (0.04 M - 0.05 M)/(4.0 s) = 0.0025 mol/L.s.

Gallium (Ga) consists of two naturally occurring isotopes with masses of 68.926 and 70.925 amu. (a) How many protons and neutron
pav-90 [236]

Answer:

neutrons_{Ga-69}=38\\\\neutrons_{Ga-71}=40

Explanation:

Hello!

In this case, since isotopes of the same element have the same number of protons and electrons but different atomic mass, we can compute the number of neutrons by subtracting the number of protons to the atomic mass of the isotope; thus, for Ga-69 and Ga-71 (rounded up to whole numbers), we obtain:

neutrons_{Ga-69}=69-31=38\\\\neutrons_{Ga-71}=71-31=40

Best regards!
