Answer:
Answer below.
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
to counteract the sourness of the acids. just did this assignment so i know this is correct
Answer:
TRIAL 1:
For “Event 0”, put 100 pennies in a large plastic or cardboard container.
For “Event 1”, shake the container 10 times. This represents a radioactive decay event.
Open the lid. Remove all the pennies that have turned up tails. Record the number removed.
Record the number of radioactive pennies remaining.
For “Event 2”, replace the lid and repeat steps 2 to 4.
Repeat for Events 3, 4, 5 … until no pennies remain in the container.
TRIAL 2:
Repeat Trial 1, starting anew with 100 pennies.
Calculate for each event the average number of radioactive pennies that remain after shaking.
Plot the average number of radioactive pennies after shaking vs. the Event Number. Start with Event 0, when all the pennies are radioactive. Estimate the half-life — the number of events required for half of the pennies to decay.
Explanation:
Answer : The height of the column in a barometer is, 10.3 m
Explanation :
To calculate the height of the column in a barometer we are using formula as:
where,
P = external pressure =
Conversion used :
h = height of the column in a barometer = ?
= density of water =
Conversion used :
g = constant of gravity =
Now put all the given values in the above formula, we get:
Therefore, the height of the column in a barometer is, 10.3 m
