1. Se preparan 750 ml de una disolución en agua, que contiene 0,00071 moles de Nitrato de potasio para adobar una carne de res. Calcular la ppm de la disolución. 2. Una muestra de 600 ml de disolución tiene 4 mg de ión fluoruro (F-). Cuántas ppm de F hay en la muestra?. Ayudaaaaaa plis
Answer:
1. 95.7 ppm
2. 6.67 ppm
Explanation:
Podemos pensar la denominación ppm como partes por millón, es un tipo de unidad que define concentración de solutos en una solución.
ppm = μg/g o si lo queremos ver en volumen, μg/mL
Quiere decir microgramos de soluto en 1 g de solución o mL de solución.
Ej 1. En primer lugar convertimos los moles de KNO₃ a gramos
0.00071 mol . 101.1 g/mol = 0.071781 g
Si pasamos los gramos a μg → 0.071781 g . 1000000 μg/ 1g = 71781 μg
Dividimos 71781 μg /750 ml = 95.7 ppm
Ej 2. Convertimos los mg a μg → 4 mg . 1000 μg/ 1 mg = 4000 μg
Ahora dividimos: 4000 μg /600 ml = 6.67 ppm

what method would you use for your hypothesis.
Could you use filtration on a solution?
Answer:
No.
Explanation:
This is because a solution is a mixture with two substances that have already dissolved in each other and so there is no residue left. Filtration works such that part of the mixture has smaller particles that can pass through the membrane of the filter paper while the bigger particles get stuck onto the paper as residue. A solution has a uniform size particle throughout and thus filtration does not work for purifying a solution.

Ublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water
Answer:
True
Explanation:
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage.
For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water which bypasses the conversion to liquid stage and goes straight to the gaseous form.

Answer:
B. Respiration
Explanation:
cellular respiration is the process where cells use glucose (C6H12O6) and oxygen gas (O2) to make carbon dioxide (CO2) water (H2O) and ATP, which is energy
formula:
C6H12O6 + 6O2 -> 6CO2 + 6H20 + 38ATP

Answer:
2Al + 3Na2SO4 -----> Al2(SO4)3 + 6 Na
Explanation:
Product should be Al2(SO4)3
Because Al contains +3 charge
And SO4 contains -2 charge
To balance this postive and negative charge we multiple +3 with 2 and -2 with 3
How does dermal tissue play a key role in transpiration?
Answer:
Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss. Stomata are specialized pores that allow gas exchange through holes in the cuticle. Unlike the stem and leaves, the root epidermis is not covered by a waxy cuticle which would prevent absorption of water.
Explanation:
A green pea plant (Gg) is crossed with a yellow pea plant (gg). What is the probability that the offspring will be heterozygous?
A.25%
B.50%
C.75%
D.100%
Answer:
50 percent
Explanation:
G g
g Gg gg
g Gg gg
since one of the plants are already heterozygous, only half will be heterozygous since the other plant is homzygous
There is 50% probability that the offspring will be heterozygous.
What is heterozygous?At a given gene locus, the existence of two different alleles. One normal allele and one mutant allele, or two separate mutated alleles, can make up a heterozygous genotype (compound heterozygote).
what is allele?An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.
so, if green pea plant (Gg) is crossed with a yellow pea plant (gg), there will be 50% probability that the offspring will be heterozygous, we can find it by making punnett square so here is the solution
Hence, the correct option is B i.e. 50%

25cm3 of a 0.4M sodium hydroxide solution was diluted into 250cm3 of water. What is the molarityof the resultant solution.
Answer:
0.04 M
Explanation:
From the question given above, the following data were obtained:
Initial volume of solution (V1) = 25 cm³
Initial Molarity of solution (M1) = 0.4 M
Final volume of solution (V2) = 250 cm³
Final Molarity of solution (M2) =?
We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.4 × 25 = M2 × 250
10 = M2 × 250
Divide both side by 250
M2 = 10/250
M2 = 0.04 M
Therefore, the resulting molarity of the diluted solution is 0.04 M

An atom of hydrogen loses its electron. What is its charge
Answer:
When an atom of hydrogen loses its electron it becomes positively charged.
Hope it will help you........Final Answer: +1
Explanation/Reasoning:
Because hydrogen is an atom (not an ion), you'll write it as H (not H+). Hydrogen (H) has one proton and one electron, so if it loses its electron, it will only have one proton. Therefore, it becomes an ion of H+. This means that the charge will be +1.

1. Suppose that there were two isotopes of Sodium.
28% of the naturally occurring sodium atoms had a
mass of 22, and 72% atoms had a mass of 23. What
would the average atomic weight of sodium be?
Answer: C. The university surveys 600 randomly selected students who attend the university. Correct
Explanation:
22.72 is the average atomic weight of sodium.
What are isotopes?Isotopes are different versions of a specific element.
1st isotopes of 22u = 28%
2nd isotopes of 23u = 72%
The average atomic weight of sodium be=
22 x 28 + 23 x72
=2272/100
=22.72
Hence, 22.72 is the average atomic weight of sodium.
