listen it has to do with limiting reactant increasing the concentration of the limiting reactant will not only increase the rate of reaction but also the amount of product because more moles of limiting reactant are present.this question is a repeat and i did it in 1 min.
please view my comment6 A student added 10.0 cm3
of 0.100 mol/dm3
hydrochloric acid to an excess of zinc. The
volume of hydrogen produced was recorded at intervals until no more gas was produced.
This was experiment P.
The experiment was repeated with a different acid solution, again using an excess of zinc.
This was experiment Q.
The graphs of the two experiments are shown on the grid below.

Q
Which acid solution would give the graph for experiment Q?
(a) 10 cm3
of 0.050 mol/dm3
hydrochloric acid
(b) 10 cm3
of 0.200 mol/dm3
hydrochloric acid
(c) 20 cm3

hydrochloric acid
(d) 20 cm3
of 0.200 mol/dm3
hydrochloric acid
i cannot find anything about powder form in this question?
but 50% is trait? 25% is normal and the other 25% is sickle cell anaemia..yes it is because the allele is carried but the trait isnt shown, as in u have the allele, but the cells dont have a sickle shape i think
i guess it z :?but 50% is trait? 25% is normal and the other 25% is sickle cell anaemia..
co dominance is basically neither is dominant over the other...right?
i also think the same thingi guess it z :?
In particle physics, antimatter is the extension of the concept of the antiparticle to matter, where antimatter is composed of antiparticles in the same way that normal matter is composed of particles. But this is nt in our syllabus :/What is Antimatter?
Please explaiin nitrogen cycle in short ?
I kno it'sIn particle physics, antimatter is the extension of the concept of the antiparticle to matter, where antimatter is composed of antiparticles in the same way that normal matter is composed of particles. But this is nt in our syllabus :/
not in our syllabus..jus kiddingIn particle physics, antimatter is the extension of the concept of the antiparticle to matter, where antimatter is composed of antiparticles in the same way that normal matter is composed of particles. But this is nt in our syllabus :/
Thankyout
THERE U GO, the siplest drawing
welcome at anytimeThankyou
circulating phagocytes produce surface glycoprotein receptors that increase their ability to adhere to the inner surface of capillary walls, enabling them to squeeze out of the capillary and be attracted to the site of infection.Q) phagocytes and lymphocytes are the same in size then why cant lymphocytes squeeze out of capillary walls in tissue fluid ?
What is oxygen debt ?
bacterium: singularAre there any different between bacteria and bacterium?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
