Because they are farther across the periodic table<span />
it's true. answer is B.
a hypothesis is a stage before formation of theory. so when we put forward a hypothesis to prove something (in scientific observation) it can be proven true with the experiments conducted.
but of course it's can be proven wrong too, after the experiments conducted. then it is disregard.
a proven hypothesis (a true hypothesis)is the reason for theories.
The formula for the monoprotic acid is taken as HA, reaction with base is as follows;
HA + NaOH ---> NaA + H₂O
Stoichiometry of acid to base is 1:1
At the neutralisation point, number of HA moles = number of base moles
Number of NaOH moles reacted = 0.100M / 1000 mL /L x 30.0 mL = 0.003 mol
Therefore number of HA moles reacted = 0.003 mol
the mass of acid 0.384 g
Therefore molar mass - 0.384 g/ 0.003 mol = 128 g/mol
Answer:
Mass and length
Explanation:
An extensive property is a property of matter that changes as the amount of matter changes. Like other physical properties, an extensive property may be observed and measured without any chemical change (reaction) occurring.
Answer : The temperature for non-catalyzed reaction needed will be 456 K
Explanation :
Activation energy : The energy required to initiate the reaction is known as activation energy.
According to the Arrhenius equation,
Since, the rate for both the reaction are equal.
..........(1)
where,
= activation energy for non-catalyzed reaction = 75 kJ/mol
= activation energy for catalyzed reaction = 49 kJ/mol
= temperature for non-catalyzed reaction = ?
= temperature for catalyzed reaction = 
Now put all the given values in the above formula 1, we get:
Therefore, the temperature for non-catalyzed reaction needed will be 456 K
