Answer:
does your son ever talk to strangers?
Explanation:
This is called
Nuclear fusion
Example is two hydrogen atoms fuse to form a helium atom
Where some of the atoms of hydrogen turn in to energy
So the answer is A
Blood should NOT be stored in an airtight container
<h3>Explanation:</h3>
We can store blood by dried it on a swab. To collect the dried blood, we should moisten a sterile cotton swab using distilled water or tap water, then shake the swab to remove excess water. Gently swab the stain with the moistened swab tip until the swab thoroughly absorbs the blood.
We can store blood also in the dried blood stains and as a scraping. The fresh collected blood, dried blood stains, wet blood stains are contained the DNA.
Airtight containers are the plastic used to make the durable containers and it is free from BPA and has been graded to be safe to be used with food supplies. The lid of this container has an innovative airtight mechanism which helps to maintain the airtight environment inside the container.
According to book "Criminal Investigation" By Ronald F. Becker on page 114, the airtight containers can cause condensation of moisture within the container and result in bacteria that can destroy, alter or contaminate the blood.
Blood components should be stored at temperatures storage in accordance with the requirements listed. Failure to follow correct storage requirements result in decreased transfusion efficacy

Answer:
c = 0.377 J/g.°C
c = 0.2350 J/g.°C
J = 27.3 J
Explanation:
We can calculate the heat (Q) absorbed or released by a substance using the following expression.
Q = c × m × ΔT
where,
c: specific heat
m: mass
ΔT: change in the temperature
<em>It takes 49.0J to raise the temperature of an 11.5g piece of unknown metal from 13.0°C to 24.3°C. What is the specific heat for the metal? Express your answer numerically, in J/g.°C</em>
Q = c × m × ΔT
49.0 J = c × 11.5 g × (24.3°C - 13.0°C)
c = 0.377 J/g.°C
<em>The molar heat capacity of silver is 25.35 J/mol.°C. How much energy would it take to raise the temperature of 11.5g of silver by 10.1°C? Express your answer numerically, in Joules. What is the specific heat of silver?</em>
<em />
The molar mass of silver is 107.87 g/mol. The specific heat of silver is:
Q = c × m × ΔT
Q = (0.2350 J/g.°C) × 11.5 g × 10.1°C = 27.3 J
