<span>When a chemist mixes oxygen gas and hydrogen gas to form water, which is composed of one oxygen and two hydrogen atoms per molecule. The hydrogen and oxygen atoms bounds together by making a bond called covalent bond.<span> In a covalent bond, two atoms are bound together because they each want to "share" each other's electrons.</span></span>

Which is associated with a fission reaction? *
podryga [215]

Answer: Radioactive waste

Explanation:

The nuclear fission reaction consists of heavy atomic particles or heavy nucleus, like plutonium and uranium and in radioactive heavy metals. In the fission reaction the nucleus get split into equal masses of particles. This process is associated with release of large amount of energy. The fission of radioactive waste can cause deadly mutations in living beings.

What's the deffinition of igneous rock
Aliun [14]
<span>Igneous rocks are those rocks that were formed through cooling and solidifying the molten materials. The best example for igneous rock is solid volcanic java. Lava are liquid that comes from a volcano, but once it is dried and solidify, it becomes a rock and called igneous rock.
Another example is the granite and basalt. And according to research igneous rock comes from the latin word ignis which means fire. Thus this says it all. From a liquid becomes a rock.

The compound gallium phosphide () is a compound semiconductor having mixed ionic and covalent bonding. The electronegativities f
9966 [12]

Answer:

0.08875

Explanation:

Hello,

In this case, the first step is to compute the difference in the electronegativity for the formed bond between gallium and phosphorous by:

\Delta E=2.1-1.6\\\\\Delta E=0.5

Thus, we can compute the percentage of ionic character by:

\%\  ionic\ character=16\Delta E +3.5 (\Delta E)^2\\\\\%\  ionic\ character=16*0.5+3.5*0.5^2\\\\\%\  ionic\ character=8.875\%

So the fraction is just:

\frac{8.875}{100}=0.08875

Which has sense since gallium phosphide is a non-polar compound.

Regards.

Thomas poured 25 mL of 0.60 M HCl into a large bottle. He then added enough water so that the new (diluted) concentration was 0.
Molodets [167]

Answer:

The answer to your question is 150 ml

Explanation:

Data

Volume 1 = 25 ml

Concentration 1 = 0.6 M

Volume 2 = ?

Concentration 2 = 0.1 M

Formula

            Volume 1 x Concentration 1 = Volume 2 x Concentration 2

Solve for Volume 2

             Volume 2 = (Volume 1 x Concentration 1)/Concentration 2

Substitution

             Volume 2 = (25 x 0.6) / 0.1

Simplification

            Volume 2 = 15 / 0.1

Result

            Volume 2 = 150 ml
