Answer:

you're going to start by balancing the carbon first. To do this, you want to times the carbon on the right by 4 so we put a 4 in front of the CO2.C4H8 + O2 --> 4CO2 + H2OWe're now going to try and balance the hydrogen by putting a 4 in front of the H2O.C4H8 + O2 --> 4CO2 +4H2OThen we're going to count the oxygens on both side and balance them by putting a 6 in front of the O2.C4H8 + 6O2 --> 4CO2 + 4H2O

Answer:

hope this helps :) please correct me if I'm wrong.

How many moles are found in a 350.mL solution of 13.5M HNO3

Answers

Answer: Moles are found in a 350.mL solution of 13.5M [tex]HNO_{3}[/tex] are 4.725 mol.

Explanation:

Given: Volume = 350 mL (1 mL = 0.001 L) = 0.350 L

Molarity = 13.5 M

Molarity is the number of moles of a substance present in a liter of solution.

Therefore, moles of [tex]HNO_{3}[/tex] present in the given solution are calculated as follows.

[tex]Molarity = \frac{moles}{Volume (in L)}\\13.5 M = \frac{moles}{0.350 L}\\moles = 4.725 mol[/tex]

Thus, we can conclude that moles found in a 350.mL solution of 13.5M [tex]HNO_{3}[/tex] are 4.725 mol.

When crossing parents with genotypes Rr and rr what will be the percentage of the genotypes of the offspring

Answers

Answer:

Explanation:

Heterozygous cross with a hom.ozygous recessive yields the following results

50% rr (hom.ogyzous recessive)

50% Rr (heterozygous dominant)

A heterozygous cross with a homozygous recessive gives the following results: 50% rr (homozygous recessive) and 50% Rr (heterozygous dominant).

What is Parental crossing?

Crossing over is a type of cellular process which occurs during the process of meiosis when chromosomes of the same type line up. When these two chromosomes – one from the mother and one from the father – line up, parts of the chromosome can be switched. Two chromosomes contain the same genes, but the genes may have different forms.

The organisms in this initial hybridization are called the parental or P generation. The progeny of the Rr x rr cross are called F1 generation which will have a heterozygous cross with the homozygous recessive giving the following results: 50% Rr (homozygous recessive) and 50% rr (heterozygous dominant)

A cross between two of the offspring in F1 generation would produce a new set of progeny called second filial generation (or F2 generation).

Thus, a heterozygous cross with a homozygous recessive gives the following results: 50% rr (homozygous recessive) and 50% Rr (heterozygous dominant).

What is indicated by the methyl-prefix?

Answers

Answer:

The molecule is a branched hydrocarbon.

Explanation:

The methyl prefix indicate the presence of a single carbon or the molecule is a branched hydrocarbon.

Prefix in IUPAC Nomenclature

The Prefix is used to show or indicate the substituents, side chains of the molecule and prefix attached to the beginning of a word and the molecules name is based on the number of carbon atoms in IUPAC nomenclature.  The International Union of Pure and Applied Chemistry (IUPAC).

For Example:

Number of carbon Atoms          Root Name                  Prefix (side group)

1                                                    meth-                             methyl-

2                                                   eth-                                ethyl-

3                                                   prop-                              propyl-

4                                                   but-                                 butyl-

5                                                   pent-                               pentyl-

6                                                   hex-                                 hexyl-

7                                                   hept-                                heptyl-

Thus, we can say that prefix tells us the number of carbon atoms in each molecule. A presence of single carbon is indicated by the methyl prefix or we can also say that the molecule is branched hydrocarbon.

La presión de vapor del agua pura a 25 oC es 24,56 mmHg y la de agua de mar es 23,99 mmHg, y si suponemos que el agua de mar sólo contiene cloruro de sodio, calcula su concentración molal.

Answers

Answer:

1.32m es la concentración de NaCl en el agua de mar

Explanation:

La disminución de presión de vapor sigue la ecuación:

P = XP⁰

Donde P es la presión de la solución = 23.99mmHg

X es la fracción molar del solvente

P⁰ la presión del agua pura = 24.56mmhg

23.99mmHg = X*24.56mmhg

0.97679 = X

La fracción molar del solvente se define como:

Moles Solvente / (Moles soluto + Moles solvente)

Asumiendo que las moles de soluto = NaCl = 1:

0.97679 = Moles solvente / (1 + Moles solvente)

0.97679 + 0.97679 Moles solvente = Moles solvente

0.97679 = 0.02321 moles solvente

42 moles solvente = 42 moles de agua.

masa de agua:

42 moles * (18.01g / mol) =758g de agua = 0.758kg

Molalidad, m, son las moles de soluto (1mol NaCl) por kg de solvente (0.758kg):

1mol / 0.758kg =

1.32m es la concentración de NaCl en el agua de mar
