1. Which of the following chemicals is a nonelectrolyte?a. molten naphthalenab. sodium hydroxide solutionc. aqueous sulfuric acid solutiond. aqueous ethanoic acid solutione. aqueous potassium iodide solution
The First thing that you must knew about Electrolyte Solution, Have the Criteria:
- The Solution that Perfect Ionized
- Strong Acid or alkali (have strong electrolyte) and weak Acid or alkali (have Weak Elektrolytes)
- Salt Solution (NaCl, KCl, and any others)
I thing Molten Napthalena Is the best Answer, Napthalena as an Organic coumpund has a Stabilized structur, so dificult to ionized.
I Hope that answer your question...
2. How many solutions do the systems of equations have?y =-1/3 x + 9y =- 2/6x
SISTEM PERSAMAAN LINEAR
Hanya 1 solusi, karena tidak ada fungsi kuadrat atau parabola, hanya ada garis/linear
yaitu :
y = -⅓x + 9
y = -⅓x
Tapi untuk garis yang seperti ini, tidak ada solusi karena memiliki gradien yang sama yaitu -⅓, tidak ada solusi yang memenuhi bahkan solusi imajiner. Pembuktiannya :
y = -⅓x + 9
y = -⅓x
_________-
0 = 9
dan kita tahu bahwa 9 ≠ 0 maka sistem linear tsb tidak memiliki solusi
PembahasanNomor 1[tex] \sf y = - \frac{1}{3} x + 9 [/tex]
mencari nilai x
[tex] \sf y = - \frac{1}{3} x + 9 \\ \sf (0) = - \frac{1}{3} x + 9 \\ \sf \frac{1}{3} x = 9 \\ \sf x = 9 \times 3 \\ \sf x = 27 [/tex]
mencari nilai y
[tex] \sf y = - \frac{1}{3} x + 9 \\ \sf y = - \frac{1}{3}(0) + 9 \\ \sf y = 0 + 9 \\ \sf y = 9 [/tex]
Nomor 2[tex] \sf y = - \frac{2}{6} x= - \frac{1}{3} x [/tex]
mencari nilaix
[tex] \sf y = - \frac{1}{3} x \\ \sf (0) = - \frac{1}{2} x \\ \sf x = - 2 [/tex]
mencari nilai y
[tex]\sf y = - \frac{1}{3} x \\ \sf y = - \frac{1}{3} (0) \\ \sf y = 0[/tex]

11. how many grams of NaC1 required to prepare each of the following solutions2500 ppm (w/v) NaC1 250 mL solutions
Penjelasan:
Formula : m NaCl (in Molar) = n ppm × mL
= 2500 ppm = masses of Salt / mL
= masses of Salt (µg) = 2500 ppm × mL
= massea of salt (µg) = 2500 ppm × 250 mL
= masses of salt (µg) = 625 µg or in mg = 625 µg × 10^-4 = 0,0625 grams
12. What are the causes of global warming and solutions for our earth.
Jawaban:
Global warming is caused by the increase of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide, methane, and water vapor, trap heat from the sun, causing the Earth's temperature to rise.There are several main causes of this increase in greenhouse gases. One is the burning of fossil fuels, such as coal and oil, for energy. This releases large amounts of carbon dioxide into the air. Deforestation and land use changes, such as the conversion of forests to agricultural land, also contribute to the increase in carbon dioxide by reducing the number of trees that can absorb the gas.
To solve these issues, we can take several actions. One solution is to switch to renewable energy sources, such as solar and wind power, which do not produce greenhouse gases. We can also implement policies to reduce our reliance on fossil fuels and encourage the use of electric vehicles.
Planting trees and protecting forests can also help to absorb carbon dioxide from the atmosphere. In agriculture, we can adopt practices that reduce methane emissions from livestock, such as changing their diet and improving manure management. Overall, to solve the problem of global warming, it is important for individuals, communities, and governments to work together to reduce greenhouse gas emissions and adopt sustainable practices.

Penjelasan:

14. The following text is for question 1-5 These days, increasing number of households use gas hot water systems, which mostly burn LPG (liquefied petroleum gas). It is a good solution if you live in an area with limited sunlight for a solar hot water system. There are two main types of hot water systems. The first is storage water heaters, which heat and store water in an insulated tank for use when it is needed. The second is instantaneous systems (or continuous flow systems), which only heat water when it's needed and don't use a storage tank. The second type is the most popular in the country, as it is more affordable. In instantaneous systems, the water is heated by a gas burner as it flows through a coiled pipe called a heat exchanger. The gas burner starts when a hot water tap is turned on. It only heats the amournt of water that is required instead of continuously heating a full tank.1. What is the topic of the text?A.
