Answer:
Hydrogen is the lightest element in the periodic table. Hydrogen is a gas of diatomic molecules and is colorless, odorless, non-toxic, and highly combustible. It is the most abundant chemical substance in the universe as it constitutes roughly 75% of all normal matter.
Answer:
A substance that is comprised of more than one kind of atom reinforced together. Blend: A mix of at least two components or mixes that have not responded to bond together; each part in the combination holds its own properties.
Explanation:
Answer:
The heat required to change 25.0 g of water from solid ice to liquid water at 0°C is 8350 J
Explanation:
The parameters given are
The temperature of the solid water = 0°C
The heat of fusion, = 334 J/g
The heat of vaporization, = 2260 J/g
Mass of the solid water = 25.0 g
We note that the heat required to change a solid to a liquid is the heat of fusion, from which we have the formula for heat fusion is given as follows;
ΔH = m ×
Therefore, we have;
ΔH = 25 g × 334 J/g = 8350 J
Which gives the heat required to change 25.0 g of water from solid ice to liquid water at 0°C as 8350 J.
