Answer:
Although hydrogen has the highest calorific value, it is not used as a domestic fuel. It is because hydrogen is a highly combustible and it reacts explosively when it comes in contact with air. And hence as a result, storing of the hydrogen gas is difficult and is dangerous at the same time.
I believe it is aluminum

Answer:
<h2>30.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
volume = final volume of water - initial volume of water
From the question
volume = 35.9 ml - 25.8 ml = 10.1 mL
We have
mass = 2.99 × 10.1 = 30.199 g
We have the final answer as
<h3>30.2 g</h3>
Hope this helps you
Climate is the answer because a meteorologist study climate
Fe (iron) has 26
protons,30 neutrons and 26 electrons. In order to calculate the binding energy,
first you need to find the total mass of all particles in the nucleus:
<span>
<span>26 x mass of proton + 30 x mass of neutron ( all in a.m.u.) =
say "m" </span></span>
<span>
Mass defect is m- 55.9207 amu, then convert it into grams and
put in equation E = mc2 to get binding energy of Fe.</span>
<span> Divide it by number of nucleons to get binding
energy per nucleon</span>.
