What's the deffinition of igneous rock

Aliun [14]

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.

Uranium-235 and uranium-238 are considered isotopes of one another

Aliun [14]

I'm confused so I'm assuming that you want to know why, so its because they have a different number of neutrons. Hope I helped if not please update your question.

Lead(II) nitrate and ammonium iodide react to form lead(II) iodide and ammonium nitrate according to the reaction Pb(NO3)2(aq)+2

alina1380 [7]

Answer:

0.519 L of a 0.590M NH4I solution is required

Explanation:

Step 1: The balanced equation

Pb(NO3)2(aq) + 2NH4I(aq) → PbI2(s) + 2NH4NO3(aq)

Step 2: Given data

Molarity of NH4I = 0.590 M

Volume of Pb(NO3)2 = 225 mL = 0.225 L

Molarity of Pb(NO3)2 = 0.680 M

Step 3: Calculate number of moles Pb(NO3)2

Number of moles = Molarity * volume

Number of moles Pb(NO3)2 = 0.680 M * 0.225L

Number of moles Pb(NO3)2 = 0.153 moles

Step 4: Calculate moles of NH4I

For 1 mol Pb(NO3)2 consumed, we need 2 moles NH4I

For 0.153 moles of Pb(NO3)2, we have 0.306 moles of NH4I

Step 6: Calculate volumen of NH4I

Molarity = moles of NH4I / volume

0.590 M = 0.306 moles / volumen

volume =0.306 moles / 0.590M

volume = 0.519 L

0.519 L of a 0.590M NH4I solution is required

How many moles do we have if we have 7.02 x 1024 molecules of

Aloiza [94]

Answer:

10 moles of methane

Explanation:

1 mole of methane contains 6.02 × 10^23 molecules (Avogadro's number)

x moles should contain 7.02 x 1024 molecules of

methane

So,

x= 7.02 x 1024 × 1/6.02 × 10^23

x= 10 moles of methane
