Nomski0: You've got the idea but you're not putting it in the right words. Try again......maybe?u cn korect me instead |

Elliotwiz1: ethanol is soluble in water because of the presence of hydroxyl ...outch#GBAM I dnt nid to say anytin again |

Tenison96:sowie i did nt put it d way it supose to,buh i gv sm idea na |
Re: SCIENCE GURUS LODGE by Nomski0(f): 10:16am On Oct 25, 2013 |
Mikebis: u cn korect me insteadOkay. It all has to do with density and volume. Density and volume have an inverse relationship. The density of water is 1, a small iron rod has a small volume hence a large density > 1 hence it sinks. The ship has a very large volume with would mean a small density < 1 hence it floats. |

Nomski0: Okay.d summary is,density of iron is grta dan dat of water. |

The gravitational constant varies from place to place on the earth's crust. Give a reason why. |

Mikebis: In a chemical rxt after 10s,10mol frm initial conc of 6mol of d reactant are dsapear.1.calculate d rate constbnt.2.calculate d half like.3.calculate d rate of reactn.chai..na wa o,no 1 to do dis little clculatns |

Nomski0: The gravitational constant varies from place to place on the earth's crust. Give a reason why. Varies cos of the earths topography. Its minimum at the equator, and increases with latitude. |
Re: SCIENCE GURUS LODGE by Nomski0(f): 10:36am On Oct 25, 2013 |
Tenison96:Not quite. |
Re: SCIENCE GURUS LODGE by Mikebis(m): 10:37am On Oct 25, 2013 |
Nomski0: The gravitational constant varies from place to place on the earth's crust. Give a reason why.because weight is dtamin by gravity nd grauitx varies ova d facd of earth |
Re: SCIENCE GURUS LODGE by Nobody: 10:38am On Oct 25, 2013 |
Nomski0: Not quite. Just edited it. Read again |
Re: SCIENCE GURUS LODGE by Nomski0(f): 10:41am On Oct 25, 2013 |
Mikebis: because weight is dtamin by gravity nd grauitx varies ova d facd of earthI know it varies but why? |
Re: SCIENCE GURUS LODGE by Nomski0(f): 10:43am On Oct 25, 2013 |
Tenison96:Well its very true. But not the answer i was hoping for. |

Switching to biology. What are Germ Layers? |
Re: SCIENCE GURUS LODGE by Mikebis(m): 10:46am On Oct 25, 2013 |
Nomski0: I know it varies but why?because d earth is spherical |
Re: SCIENCE GURUS LODGE by Mikebis(m): 10:52am On Oct 25, 2013 |
Tenison96: Switching to biology.germ layer rfrd to as germ epithelium whch is a grp of cell formd during animal.we av 3 germs layer whch are ectodem d outer part,mesodem d mdle part nd endodem d ina part |
Re: SCIENCE GURUS LODGE by Nomski0(f): 10:56am On Oct 25, 2013 |
Tenison96: Switching to biology.Germ layers are germinal epithelium tissues. They are pronounced in vetebrates and are mostly involved in embryogenesis. |

FrancisTony: Mehn, this group is cool and i need a cracking chemistry question.chemistry? Here u go An unknown compound contains only carbon, hydrogen, and oxygen. Combustion of 7.50 g of this compound produced 11.0g of carbondioxide and 4.50 g of water. How much C and H were in the original sample? Good morning gurus |

Nomski0: The gravitational constant varies from place to place on the earth's crust. Give a reason why.because the earth isn't a perfect sphere ...itz flattened at d poles, hence, the distance from d suface, to the center of gravity of the earth, varies at different locations ....in othr wordz ....since itz flattened at the poles, the poles are closer to the centre of gravity, so the pull will be felt more at the poles .... |

Nomski0: The gravitational constant varies from place to place on the earth's crust. Give a reason why.it is because the earth is not a perfect sphere.. Its sides are flattened |

What are the bypass in gluconeogenesis and the enzymes responsible? |
Re: SCIENCE GURUS LODGE by Nobody: 11:16am On Oct 25, 2013 |
State Doppler EffecT? |
Re: SCIENCE GURUS LODGE by Nomski0(f): 11:16am On Oct 25, 2013 |
Shape of the earth is correct. Y'all were right. Gluconeogenesis is a process which involves many enzymes, so which of them are you referring to. And what is bypass |
Re: SCIENCE GURUS LODGE by Nomski0(f): 11:19am On Oct 25, 2013 |
FrancisTony: State Doppler EffecT?The velocity of a sound decreases with increasing distance. The frequency/intensity of a sound reduces as the hearer moves further away from the sound or as the source of the sound moves away from the hearer. |

I_am_Sylva: chemistry?molar mass of CO2=44, molar mass of H2O=18 taking C as carbon 11g of CO2 was produced .. So 12/44=C/11 C = 3grams or 0.25mol . . 4.5g of H2O was produced... So 2/18=H/4.5 H = 0.5 grams or 0.5mol . . Oxygen 7.5 - (3 + 0.5) =3.5g of oxygen or 0.22mol solving furda, ..the empirical formula of the compound that waz combusted is: CH2O |
Re: SCIENCE GURUS LODGE by Mikebis(m): 11:34am On Oct 25, 2013 |
I_am_Sylva: chemistry?let me gv it a try,buh no abuse me if am wrng o. Let d unknw cmpnd b x usn equilibrium constant ur product/reactant kc=[11.0][4.50]/[7.50] xo we av 6.6 there4 usn 6.6 to divd d molar mass of C nd H. We av 6.6/12=0.55 for C 6.6/2 =3.3 for H |
