I believe the statement above is true. <span>A </span>carbohydrate<span> is a </span>biological molecule<span> consisting of </span>carbon<span> (C), </span>hydrogen<span> (H) and </span>oxygen<span> (O) atoms, usually with a hydrogen–oxygen </span>atom ratio of 2:1. <span>When a </span>carbohydrate<span> is broken into its component sugar molecules by </span>hydrolysis<span> (e.g. sucrose being broken down into glucose and fructose), this is termed saccharification.</span>
CH2O2 formic acid I believe so
Answer:
one potassium, one nitrogen and three oxygen
Explanation:
potassium is K, nitrogen is N and oxygen is O
5.57 × 10²⁵ molecules of Br₂ will have a mass of 14862.33g
HOW TO CALCULATE MASS:
- The mass of an element can be calculated by multiplying the number of moles by its molar mass. That is;
mass (g) = moles (mol) × molar mass (g/mol)
- However, the number of moles in 5.57 × 10²⁵ molecules of Br₂ will be calculated first by dividing the number of molecules by Avogadro's number.
no. of moles = 5.57 × 10²⁵ ÷ 6.02 × 10²³
no. of moles = 5.57/6.02 × 10²⁵-²³
no. of moles = 0.93 × 10²
no of moles = 93 moles
Molar mass of Br₂ = 159.81g/mol
Mass of Br₂ = 93 × 159.81
Mass of Br₂ = 14862.33g
- Therefore, 5.57 × 10²⁵ molecules of Br₂ will have a mass of 14862.33g.
