Answer:

The heat generated per gram of sample in calories is 0.87 g

Explanation:

Given that,

A calorimeter made from a can is used to measure the calories in a peanut.

During the experiment, the  measured calories were 35% of the true/accepted value given by references

Suppose, the mass of peanut is 0.4 g and find the

We need to calculate the heat generated per gram of sample in calories

Using formula of heat generated

q=\dfrac{q_{penut\ calorimeter}}{m_{peanut}}

Put the value into the formula

q=\dfrac{0.35}{0.4}

q=0.87\ g

Hence, The heat generated per gram of sample in calories is 0.87 g

Explanation:

  1. area of rectangle=l×b
  • 15=5×b
  • b=3cm

2.area of rectangle=l×b

  • 28=l×4
  • l=7cm

3. perimeter of square=4×L

  • 24=4×L
  • L=6cm

4. perimeter of rectangle=2(L+b)

  • 14=2(4+b)
  • 14=8+2b
  • 2b=6
  • b=3cm

Consider the double replacement reaction given below: HgNO3(aq) + KBr(aq) → HgBr (??) + KNO3(??)The state of matter for HgBr wou
Andreas93 [3]

Answer: The state of maater for HgBr is solid.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

HgNO_3(aq)+KBr(aq)\rightarrow HgBr(s)+KNO_3(aq)
