Option (d) is the correct answer.
According to law of conservation of mass, mass can neither be created nor it can be destroyed as it can only be transferred from one form to another.
This means that in a chemical reaction the mass of reactants is equal to the mass of products.
Total mass of reactants is as follows.
= 116 g/mol
Total mass of products is as follows.
= (2 \times 58) g/mol
= 116 g/mol
Hence, we can conclude that mass is conserved in both physical and chemical changes.
B. eneegy is the answer of your question
C. Physical and chemical
Matter can be conserved in both physical and chemical changes.
ENERGY IS CONSERVED in human being in the form of glycogen and energy is conserve and release in exothermic and endothermic reactions
energy or density
False. No matter what you do mass cannot be destroyed or removed.
It is Mass in conserved in physical changes
venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.
here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.
so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
