D. Pentane. Pentane has 5 Carbon and 12 Hydrogen, like the molecule shown.
No, darker colors like purple and blue have higher wave frequency which transmit more energy.
First, the symbol for sodium oxide is Na₂O
Each Na (sodium) has a charge of 1+, and each O has a charge of 2- :
Na₂¹⁺O²⁻
There are two Na's, however, and each one is 1+, however, so the Na₂ has a total charge of 2+. Because of this, the 2+ from the 2 Na's and the 2- from the O cancel each other out to make 0.
Answer:
\text{0.30 cm}^{3} \times \left (\dfrac{10^{-2}\text{ m}}{\text{1 cm}}\right )^{3} = 3.0 \times 10^{-7} \text{ m}^{3}
Explanation:
0.030 cm³ × ? = x m³
You want to convert cubic centimetres to cubic metres, so you multiply the cubic centimetres by a conversion factor.
For example, you know that centi means "× 10⁻²", so
1 cm = 10⁻² m
If we divide each side by 1 cm, we get 1 = (10⁻² m/1 cm).
If we divide each side by 10⁻² m, we get (1 cm/10⁻² m) = 1.
So, we can use either (10⁻² m/1 cm) or (1 cm/10⁻² m) as a conversion factor, because each fraction equals one.
We choose the former because it has the desired units on top.
The "cm" is cubed, so we must cube the conversion factor.
The calculation becomes

The volume of NaOH solution is 0.532 L.
<em>Step 1</em>. Calculate the <em>moles of NaOH</em>.
Moles = 11.5 g NaOH × (1 mol NaOH/40.00 g NaOH) = 0.2875 mol NaOH
<em>Step 2</em>. Calculate the <em>volume of NaOH</em>
Volume = 0.2875 mol NaOH × (1 L NaOH/0.540 mol NaOH) = 0.532 L
