Answer:
8.8 yards per second
Explanation:
50 - 20 = 30 yards
30 yards/3.4 seconds = 8.8235
First, recognize that this is an elimination reaction in which hydroxide must leave and a double bond must form in its place. It is likely an E2 reaction. Here is an efficient mechanism:
1) Pre-reaction: Protonate the -OH to make it a good leaving group, water. H2SO4 or any strong H+ donor works. The water is positively charged but still connected to the compound.
2) E2: Use a sterically hindered base, such as tert-butoxide (tButO-) to abstract the hydrogen from the secondary carbon. [You want a sterically hindered base because a strong, non-sterically hindered base could also abstract a hydrogen from one of the two methyl groups on the tertiary carbon, and that leads to unwanted products, which is not efficient]. As the proton of hydrogen is abstracted, water leaves at the same time, creating an intermediate tertiary carbocation, and the 2 electrons in the C-H bond immediately are used to make a double bond towards the partial positive charge.
In the products we see the major product and water, as expected. Even though you have an intermediate, remember that an E2 mechanism technically happens in one step after -OH protonation.
Answer:
heat can move from any source but if we are being legitimate it moves from convection
Explanation:
The mass of the product is <em>98.78 g.</em>
The word equation is
aluminum + chlorine → product
20.00 g + 98.78 g → <em>x</em> g
If each reactant is completely consumed, the <em>Law of conservation of Mass </em>tells us the mass of the product must be 98.78 g.
Answer:
that is all I know sorry hope that may help you :)
Explanation:
Indicator is a substance which shows different colors in acidic and basic medium. Indicators can be natural (derived from natural sources) or artificial ( man-made) for example :
*Litmus is an indicator. Acid turns blue litmus into red while base turns red litmus into blue
* Turmeric solution does not show change in color (remains yellow) in acidic solution and turns red in basic solution.
