Answer: X2Y5
Explanation:
X has 2 dots and Y has 5 dots
At STP volume is 22.4 L
Molar mass NO₂ = 46.0 g/mol
1 mole ---------- 22.4 L
? mole ---------- 11.4 L
moles = 11.4 * 1 / 22.4
moles = 11.4 / 22.4
= 0.5089 moles of NO₂
Mass NO₂ :
moles NO₂ * molar mass
0.5089 * 46.0
= 23.4094 g of NO₂
hope this helps!
There are many ways to test and identify metal. The easiest way is observing its color. Also how reflective it is. Other ways would be boiling point, melting point, density, or conductivity of the metal.

The following types of bonds exists between the listed atoms;
- Si and O - polar covalent
- O and O - Covalent
- C and H - Covalent
- Li and F - ionic
- Ba and S - ionic
<h3>What is a polar covalent bonds?</h3>
A bond is polar covalent when the electronegativity difference between the bonding atoms is above that found in a nonpolar covalent bond. Now we shall see the types of bonds between these atoms.
- Si and O - polar covalent
- O and O - Covalent
- C and H - Covalent
- Li and F - ionic
- Ba and S - ionic

Answer:
This strand contains nucleotides that are complementary to those in the template sequence. Base pairing ensures that the sequence of nucleotides in the existing template strand is exactly matched to a complementary sequence in the new strand, also known as the anti-sequence of the template strand
