When a sample of aqueous hydrochloric acid was neutralized with aqueous sodium hydroxide in a calorimeter, the temperature of 148.3 g of water surrounding the reaction increased by 5.43 degrees * C . If the specific heat of water is 1.00 cal/(g C) , calculate the quantity of energy in calories involved in this neutralization reaction. (Ignore the heat gain by the calorimeter)

805.3cal

Explanation:

All neutralization reactions produce heat when occurs.

The reaction of HCl with NaOH produce heat increasing the aqueous medium in 5.43°C. The equation of the released energy is:

Q = S×m×ΔT

Where Q is heat,

S is specific heat of the solution (1.00cal/g°C)

m is mass of water: 148.3g

ΔT is change in temperature: 5.43°C

Q = 1.00cal/g°C×148.3g×5.43°C

Q = 805.3cal

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

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.
