Determine the number of valence electrons for magnesium
12345 [234]

Answer:

Magnesium has 2 valence electrons.

Explanation:

The atomic number of magnesium is 12. This means that it has 12 protons and 12 electrons. The first electron shell can hold 2 electrons, the second can hold 8, so the third will have 2 electrons. The outermost shell of the atom has two electrons. Therefore, magnesium has 2 valence electrons.

3) If an electrical appliance has 150.0 V applied causing a current of 2.34 amps, what is the
eimsori [14]

The resistance of the appliance is 64.1 Ω.

<u>Explanation:</u>

As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,

V = IR

Where V is the voltage (V) = 150.0 V

I is the current (amps) = 2.34 amps

R is the resistance (ohm) or Ω = ?

Now we have to rearrange the equation to get the resistance as,

$R = \frac{V}{I}

Now we have to plug in the values as,

$ R = \frac{150}{2.34}

   = 64.1 Ω

So the resistance of the appliance is 64.1 Ω.

The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH). CO2 + 2LiOH mc011-1.jp
Sunny_sXe [5.5K]
From the given balanced chemical equation,
                            CO2 + 2LiOH --> Li2CO3 + H2O
we can conclude that for every 2 moles of LiOH, we need a mole of CO2. Calculate first the number of moles of CO2 by dividing the given mass by the molar mass giving us an answer of 0.58 moles. Using proportionality,
                             0.58 / x = 1 / 2
The value of x is equal to 1.16 moles.
