Chemistry
1 answer:
grigory [225]4 years ago
7 0

Answer:

1-true

2-false

3-false

4-true

Explanation:

The reaction rates depend on many factors, one of them is the amount of reagents, the temperature, and the presence or absence of catalyst.

Catalysts accelerate the reaction rate, as does the increase in the amount of reactants.

On the other hand, low temperatures, low amounts of reagents could slow down.

Is titanium or magnesium higher in the reactivity series?Explain your answer
Jet001 [13]

MAGNESIUM IS HIGHER IN THE REACTIVITY SERIES.

Explanation:

The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities.

The reactivity series provides information whether a metal can displace another in a single displacement reaction. It can also be used to obtain information on the reactivity of metals towards water and acids.

Magnesium reacts very slowly with cold water, but rapidly  in boiling water, and very vigorously with acids.

Titanium reacts with concentrated mineral acids, pyrometallurgical extraction using magnesium,  or less commonly other alkali metals, hydrogen or calcium in the Kroll process .
