Answer:
Making models
Explanation:
Classifying is the grouping together of items that are alike in some way. Answer: Making models involves creating rep- resentations of complex objects or processes.
The correct answer would be 0.1505 M/s. Given the rate of disapperance of HBr, we can easily calculate the rate of apearance of the products by looking at the coefficients of the substances in the reaction. In this case, for every two moles of HBr, 1 mole of Br2 is being produced so the reaction rate would be:
- 1/2 (r(HBr)) = rBr2
- 1/2 (-0.301) = rBr2
Rate of appearance of Br2 = 0.1505 M/s
Answer:
B, increases rate of collisions
Explanation:
Answer:
Hexanoic acid is water insoluble and sodium hexanoate is water soluble
Explanation:
Hexanoic acid is water insoluble because of presence of long 6 membered non polar and hydrophobic hydrocarbon chain.
When hexanoic acid is treated with NaOH, it is converted to an ionic salt sodium hexanoate which is highly soluble in water because of it's ionic nature.
So, the reaction is given as:
Hexanoic acid + NaOH 
Sodium hexanoate + water
Reaction in terms of molecular structure has been shown below.
Hi ;)!
So:
4.2 mm (/10) = 0.42 cm
2.0 cm + 2.6 cm + 0.42 cm = 5.02 cm ;)
