Given the following chemical reaction:202 CH4 CO2 2 H20What mass of CH4 is required to completely react with 100 grams of O2?
Helga [31]
Molar mass:

O₂ = 32.0 g /mol             CH₄ = 16.0 g/mol

2 O₂ + CH₄ = CO₂ + 2 H₂O

2 x 32 g O₂ ---------------> 16 g CH₄
100 g O₂ ------------------> ( mass of CH₄)

mass of CH₄ = 100 x 16 / 2 x 32

mass of CH₄ = 1600 / 64

= 25 g of CH₄

hope this helps!

A part of an mrna molecule with the following sequence is being read by a ribosome: 5' ccg-acg 3' (mrna). the anticodon loop of
monitta

The first trna's anticodon loop, which will complement this mrna, is 3' GGC 5'.

<h3>What is anticodon ?</h3>

A complementary codon in messenger RNA binds to a triplet of nucleotide bases in transfer RNA that identifies the amino acid delivered during protein synthesis at a ribosome.

A codon is a trio of nucleotides, or triplet, that can be found on mRNA and codes for a certain amino acid when it is translated. A bond is created when an anticodon, which is a three-nucleotide sequence on tRNA, meets with the matching sequence on mRNA.

Each tRNA has a trio of bases known as an anti-codon. to determine the entire anti-codon sequence required to match a certain strand of mRNA. to match the complementary nucleotides in the mRNA sequence.

To learn more about anticodon from the given link:
