Respuesta:
16 gramos de vitamina C y 8 gramos de colorantes.
Explanation:
Debemos multiplicar el porcentaje de cada componente por la cantidad total (100 %) de zumo.
800 g de zumo = 100%
- Tenemos un 2 porciento (2 en 100 o 2/100) de vitamina C. Por lo tanto, la cantidad en gramos de vitamina C es:
2/100 x 800 g = 16 g
- Tenemos un 1 porciento de colorantes en el zumo (1/100). Por lo tanto, la cantidad en gramos de colorantes es:
1/100 x 800 g = 8 g

What is the proper compound formula for Hydrogen Cyanide?
A.) H(CN)2
B.) H2(CN)
C.) HCN
D.) H2(CN2)
Answer:
C
Explanation:
Cyanide's formula can be found either on google on on a reference table at the "polyatomic ions" table. Hydrogen, H, has a charge of 1+ when bonded, and cyanide has a charge of 1- overall, so they will be in a one to one ratio while bonded. As such, the equation is HCN.

Answer:
electron
Explanation:
hope this helps:)
According to the research, electrons are the part of the atom that is involved in chemical reactions.
What are electrons?It is a subatomic element that is located around the nucleus of the atom, formed by neutrons and protons and is the lightest essential particle that makes up an atom.
In chemical reactions reagents or reactants are involved, specifically in oxidation-reduction reactions electrons are transferred between chemical species, the oxidizing substance loses electrons and the other gains electrons.
Therefore, we can conclude that according to the research, electrons are the part of the atom that is involved in chemical reactions.

Explanation:
which other metal can substitute (in place of) iron explain you answer.. Aluminum, copper or iron?
Answer+Explanation:
Titanium ( in place of iron)
Titanium could be an excellent replacement for iron when it comes to tensile strength versus weight. It would be the first choice as a building material metal and building skeletons/bridges would use titanium instead of iron.
Magnesium alloys (in place of aluminum)
Magnesium alloys potentially met the present demands for lighter and reliable construction. With comparable specific stiffness, higher specific strength and energy absorption magnesium alloys have the potential to replace steel and aluminum alloys.
aluminum (in place of copper)
Most non-copper metal cabling is aluminum, and it is often used in areas where copper is not a likely alternative. However, it is used more now as a replacement than it has ever been. It is cheaper than copper, and its relative density allows for more cable to be made from a ton of aluminum than a ton of copper.

The white Dwarfs are a group of stars that are-
A)Extremely bright and hot
B)Low in brightness but are average to high in temperature
C)Average in brightness but high in temperature
D)Average in brightness and average in temperature
Answer: A
Explanation:
The white Dwarfs are a group of stars that are extremely bright and hot. Hence option A is correct.
What are stars?Stars are defined as any large gaseous heavenly body that emits light as a result of its own internal energy sources. Stars are celestial bodies that generate their own energy through the fusing of gases. They resemble bright orbs that burn gas and produce energy. Our solar system's star, the Sun, generates energy through the fusion reaction in which helium transforms into hydrogen.
When a white dwarf first forms, it is extremely hot, but because it has no energy source, it will gradually cool as it emits its energy into space. This implies that the color temperature of its radiation, which is initially high, will gradually decrease and turn red. After using up all of their nuclear fuel, stars like the Sun become white dwarfs.
Thus, the white Dwarfs are a group of stars that are extremely bright and hot. Hence option A is correct.

Answer:
A. Convert the 200 mol of water to kilograms of water.
Explanation:
To find the molality of 10mol of NaCl in 200mol of water, convert the 200mol of water to kilograms of water.
Molality is one of the several ways of measuring concentration of a solute in a solvent;
Molality = [tex]\frac{number of moles of solute}{mass of solvent}[/tex]
To solve this problem, simply convert the 200mole to mass of water.Sodium is a non-metal

Ammonia (NH3) is widely used as a fertilizer
and in many household cleaners. How much
ammonia is produced when 3.55 mol of hydrogen gas react with an excess of nitrogen
Answer:
Mass of ammonia produced = 40.29 g
Explanation:
Given data:
Number of moles of H₂ = 3.55 mol
Mass of ammonia produced = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Now we will compare the moles of ammonia with hydrogen
H₂ : NH₃
3 : 2
3.55 : 2/3×3.55 = 2.37 mol
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 2.37 mol × 17 g/mol
Mass = 40.29 g

Answer:
Sustancia Masa (g) Composición (% m/m)
Proteínas 5,5 4,4
Azúcares 5,0 4,0
Sodio 0,06 0,048
Potasio 0,15 0,12
Explanation:
Para calcular la composición porcentual en masa de las sustancias debemos usar la siguiente ecuación:
[tex] \%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 [/tex]
En donde:
[tex]m_{s}[/tex] es la masa de la sustancia
[tex]m_{sol}[/tex] es la masa del yogurt = 125 g
Para las proteínas:
[tex] \%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 = \frac{5,5 g}{125 g} \times 100 = 4,4 \% [/tex]
Para los azúcares:
[tex] \%_{m/m} = \frac{5,0 g}{125 g} \times 100 = 4,0 \% [/tex]
Para el sodio:
[tex] \%_{m/m} = \frac{0,06 g}{125 g} \times 100 = 0,048 \% [/tex]
Para el potasio:
[tex] \%_{m/m} = \frac{0,15 g}{125 g} \times 100 = 0,12 \% [/tex]

Global warming is mainly due to
CFC's
Ozone Holes
Nitric and sulfuric acids
Greenhouse gases
Answer:
Explanation:
Glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace. It has become clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than at any time in the last 800,000 years.
We often call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place. While many people think of global warming and climate change as synonyms, scientists use “climate change” when describing the complex shifts now affecting our planet’s weather and climate systems—in part because some areas actually get cooler in the short term.
Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts. All of those changes are emerging as humans continue to add heat-trapping greenhouse gases to the atmosphere, changing the rhythms of climate that all living things have come to rely on.
What will we do—what can we do—to slow this human-caused warming? How will we cope with the changes we've already set into motion? While we struggle to figure it all out, the fate of the Earth as we know it—coasts, forests, farms, and snow-capped mountains—hangs in the balance.
