In which layer(s) would a solid cube with 6 cm sides and mass of 270 g float? Explain.

The buoyancy of an object is dictated by its density. So let us calculate for density, where:density = mass / volume
Calculate the volume first of a solid cube:volume = (6 cm)^3 = 216 cm^3 = 216 mL
Therefore density is:density = 270 g / 216 mLdensity = 1.25 g / mL
Therefore this object will float in the layer in which the density is more than 1.25 g / mL.

Answer:

Oxidation  half  reaction  is  written   as    follows when  using  using  reduction potential  chart

example  when  using  copper  it is  written  as  follows

CU2+   +2e-  --> c(s)  +0.34v

oxidasation  is the  loos  of  electron  hence copper oxidation  potential  is  as  follows

cu (s)  -->  CU2+   +2e    -0.34v

The decomposition of methanol, ch3oh(g), to form ch4(g) and o2(g) absorbs 252.8 kj of heat per mole of oxygen formed. write a ba
Svetllana [295]
The thermochemical equation is the chemical equation including the net change of enthalpy (heat).

The chemical equation for the decomposition of methanol to form methane and oxygen is:

2CH3OH --> 2CH4 + O2

The thermochemical equation is:

2CH3OH ---> 2CH4 + O2  - 252.8 kJ

Note that the heat is placed as negative at the right side because it is absorbed during the decomposition, so the environment will have 252.8 kJ less per each mole of O2 produced.

You can equivalently write:

2CH3OH + 252.8 kJ --> 2CH4 + O2

The mass of .10 moles of iron is:
Stels [109]

Answer:

<em>so mass in gram=560grams</em>

Explanation:

number of moles=10moles

molar mass=56grams/moles

mass in gram of Fe=?

as we know that

number of moles=\frac{mass in gram}{molar mass}

<em>evaluating the formula</em>

<em>number of moles×molar mass=mass in gram</em>

<em>mass in gram=10moles×56grams/moles</em>

<em>mass in gram=560grams</em>

<em>i hope this will help you :)</em>
