Behavior patterns which are already present at birth are called ____

quester [9]

When a liquid evaporates, it releases heat energy into the surroundings because the molecules obtain energy ( when they are being evaporates), causing the molecules to vibrate fast and escape into the atmosphere!

How does the shape of an enzyme affect its function?

lutik1710 [3]

Each enzyme's active site is suitable for one specific type of substrate – just like a lock that has the right shape for only one specific key. Changing the shape of the active site of an enzyme will cause its reaction to slow down until the shape has changed so much that the substrate no longer fits.

Some scientists believe that life on Earth may have originated near deep-ocean vents. Balance the following reactions, which are

goldenfox [79]

Answer :

(1) The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

(1) The unbalanced chemical reaction is,

$CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the $CH_3SH$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The unbalanced chemical reaction is,

$H_2S(g)+CO(g)\rightarrow CH_3CO_2H(g)+S_8(s)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '8' put before the $H_2S\text{ and }CO$ and the coefficient '4' put before the $CH_3CO_2H$ we get the balanced chemical equation.

The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

1 mole of hcl(g) has a greater entropy than 1 mole of hbr(g). true or false

yan [13]

False. Due to:
Entropy increases with molecular size (mass of compound)
HBr has greater molecular size (molar mass) than HCl
The value of standard entropy of HCl(g) is 187 joules/ kelvin
The value of standard entropy of HBr(g) is 199 joules / kelvin
