Answer:

The carrying capacity of this population would be 125 we know this because we see that this number occur multiple times and seems to be the tipping point after which the number of the population always go down

Answer:

Ionic compounds are compounds whereas metals are elements. Ionic compounds are electrolytes whereas metals are conductors. Ionic compounds are brittle whereas metals are malleable and ductile. ... Most ionic compounds will dissolve in polar solvents like water whereas metals will either be insoluble or react with water.

Explain why the product at the negative electrode is not always a metal.

Elena-2011 [213]

Answer:

Whether you get the metal or hydrogen during electrolysis depends on the position of the metal in the reactivity series: the metal will be produced if it is less reactive than hydrogen. hydrogen will be produced if the metal is more reactive than hydrogen.

Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hy

kolezko [41]

Answer:

number of hydrogen atom in 1.8 mole of NH2OH = $9.8\times 10^{22}$

Explanation:

percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule

= $\frac{3\times 1}{14+3+16}$ \times 100

= 9.09 percentage

therefore number of moles in 1.8 moles of hydroxy amine = $\frac{9.09}{100}\times 1.8$

= .16 moles of hydrogen

number of hydrogen atom = (number of moles )×(avagadro number)

= $9.8\times 10^{22}$ atoms of hydrogen

You are given 24.3 grams of Mg and combine it with 32.1 grams of Sulfur, what is the mass of MgS? *

koban [17]

Answer:

ExplanatioFirst let us compute for the molar mass of Mg(OH)2.

molar mass = 24.3 + 2 (16) + 2(1.0)

molar mass = 58.3 g/mol

So the mass is then:

mass = 3.2 mol * (58.3 g/mol)

mass = 186.56 gramsn:
