Jamie rolls a 6-sided die 30 times and determines that the experimental probability of rolling a 2 is Start Fraction 1 over 15 E

anyanavicka [17]

Answer:

Conduct more trials

Explanation:

Theoretical Probability can be defined as what someone is expecting to happen

Experimental Probability on the other hand, is defined as what actually happens.

Probability is usually calculated in the same way for experimental probability and that of theoretical probability. You divide the total number of possible ways in which a particular outcome can happen, by the total number of outcomes itself.

In Experimental probability, the more times a probability is tried, it gets closer and even more closer to theoretical probability.

So, for the question, Jamie should improve the number of tries more, so as to get his experimental probability results to be closer to the theoretical probability result.

In Ontario, some electricity comes from coal-burning generators. Coal is a natural form of carbon that has a large amount of sul

irinina [24]

Answer:

a)

$C(s)+O_{2}(g) \rightarrow CO_{2}(g)$

$S(s)+O_{2}(g) \rightarrow SO_{2}(g)$

b)

Sulphurdioxide

c)

$SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)$

$SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)$

d)

Incomplete combustion produce harmful gases.

Explanation:

a)

Carbon reacts with atmospheric oxygen to form carbondioxide as well as sulphur dioxide.

The chemical equations are as follows.

$C(s)+O_{2}(g) \rightarrow CO_{2}(g)$

$S(s)+O_{2}(g) \rightarrow SO_{2}(g)$

b)

Sulfur dioxide is very harmful to the environment to cause acid rains.

This harmful gas mix with rain water to form sulphuric acid.

c)

The balanced chemical equation for the reaction that produces harmful environmental effects is as follows.

$SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)$

$SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)$

$SO_{3}(g) +H_{2}O(l) \rightarrow H_{2}SO_{4}(l)$

d)

In the absence of proper amount of oxygen required for combustion, incomplete combustion will take place which will result in formation of more carbondioxide an other harmful gases.
