Na = 22.99 amu
Cl = 35.45 amu
NaCl = 22.99 + 35.45 => 58.44 g/mol
Answer:
<u>The temperature difference is</u>
Explanation:
The formula that is to used is :
ΔΔ
<em>where ,</em>
- <em>Δ is the heat supplied in calories = 300cal</em>
- <em> is the mass of water taken = m (assumed)</em>
- <em>Δ is the change in temperature</em>
- <em> is the specific heat of water = </em>
ΔT :
Answer is: <span>solid wood.
There are </span>five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).
<span>In solid, molecules are closely packed, stiff and do not changes of shape or volume. S</span><span>olid object (in this example wood) does not take on the shape of its container.
</span>Liquids (in this example water) <span>have definite volume, but no fixed shape.
</span>Gases (in this example nitrogen and neeon) not have definite volume and fixed shape, it depends on its container.
