Answer:
d
Explanation:
i think its d but im not sure.
The molar mass of K is 39, Cr is 52, and O is 16. The rough calculation of these numbers are 294.
Answer:
3,5-dichlorohex-1-ene
Explanation:
The compound is; H2C=CH-C(Cl)H-CH2-C(Cl)H-CH3. We can rightly call this compound by the name, 3,5-dichlorohex-1-ene.
We arrived at this name by first counting the longest parent carbon chain, that gives hexane. The compound has a double bond at the 1-position. Also, there are two substituent chlorine atoms at positions 3 and 5 in the structure, hence the name given.
Molar mass:
CH₄ = 12 + 1 x 4 = 16.0 g/mol
CO₂ = 12 + 16 x 2 = 44.0 g/mol
Balanced <span>equation :

<span>CH</span>₄<span> + 2 O</span>₂<span> = CO</span>₂<span> + 2 H</span>₂<span>O
</span>
16.0 g CH₄ --------------- 44.0 g CO₂
(mass of CH₄) ----------- 46.4 g CO₂
mass of CH₄ = 46.4 x 16.0 / 44.0
mass of CH₄ = 742.4 / 44.0
= 16.87 g CH₄
hope this helps!
Explanation:
Hence in this experiment, the importance of experiment is being tested, as it is added only in one set of plant.
A manipulated variable is an independent variable whose amount can be changed during an experiment.
Here the fertilizer is a manipulated variable.
