Answer:

Lead to Sulfur = 2 : 1

Explanation:

Given

Represent lead with L and Sulfur with S

L1 = 6.46g for S1 = 1 g

L2= 3.23g for S2 = 1 g

Required

Determine the simple whole number ratio of L to S

Divide L1 by L2

L = L1/L2

L = 6.46g/3.23g

L = 2

Divide S1 by S2

S = 1g/1g

S = 1

Represent L and S as a ratio:

L : S = 2 : 1

Hence, the required ratio of Lead to Sulfur is 2 to 1

Limit sodium intake to less than ____________ per day. Limit saturated fat intake to less than ____________ of daily kilocalorie
kotykmax [81]

Answer:

Limit sodium intake to less than <em><u>2,300mg</u></em> per day. Limit saturated fat intake to less than <em><u>10% </u></em>of daily kilocalories. Limit intake of added sugars to less than<em><u> 5% </u></em>of daily kilocalories. Limit intake of alcohol to less than <em><u>3 drinks </u></em>per day for men or less than <em><u>2 drinks</u></em> per day for women.

Explanation:

The human body has been designed such that there are dietary requirements and benefits these intakes give the body. However, excess consumption of certain foods, could be far more detrimental both on the short and long run.

Sodium is majorly consumed in the form of salt (Sodium chloride). When eaten in the right quantity, it serves as an electrolyte which maintains fluid balance in the body however, when taken in excess, it pulls too much fluid, leading to high blood pressure. The recommended salt intake therefore, is less than 2,300mg daily.

Saturated fat when consumed, is a good source for the body to convert diet to energy, keeping the blood sugar levels constant. Lard, fatty meats are examples of saturated fat. However, when consumed in large amounts, saturated fats can cause cholesterol build up in blood vessels, increasing the risk of heart disease. Its intake should therefore be limited to less than 10% of daily kilocalories.

Added sugars are sources of energy to the body however, when taken in large amounts, could impede normal metabolism in the body. Added sugars should be restricted to less than 5% of daily kilocalories in diet.

Alcohol intake such as in wine, when done in moderation, has been shown to reduce the risk of heart diseases. However, when taken in excess, tolerance builds and exposes the body to the risk of conditions such as liver disease, alcohol use disorder.

Which example is a long-term environmental change? La Niña El Niño climate change small asteroid impact
anyanavicka [17]

The correct answer is C. Climate change

Explanation:

Long-term environmental changes occur as major events affect the environment and ecosystems indefinitely. These events differ from short-term environmental changes because the effect of short-term environmental changes is mainly temporary. Also, long-term changes are usually gradual.

Climate change is an example of long-term environmental changes because this implies indefinite and major changes in weather patterns and ecosystems. For example, it is believed climate change will decrease the amount of ice in Earth, change sea level, and lead to the extinction of dozens of species. This does not occur with events such as el niño or a small asteroid impact that affect the environment for a short time and do not imply major changes.

What is the mass of 4.38 x 10^24 formula units of sodium chloride (NaCl)?
lana66690 [7]

Answer:

Mass = 427.05 g

Explanation:

Given data:

Formula units of sodium chloride = 4.38 ×10²⁴

Mass of NaCl = ?

Solution:

One mole contain formula units = 6.022 ×10²³

4.38×10²⁴ formula units × 1mol /6.022 ×10²³ formula units

0.73 ×10¹ mol

7.3 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 7.3 mol × 58.5 g/mol

Mass = 427.05 g

For the combustion reaction of C9H12 in O2: how many moles of O2 is required to react with 0.67 mol C9H12?
miskamm [114]

Answer:

8.0 mol O₂

Explanation:

Let's consider the complete combustion reaction of C₉H₁₂.

C₉H₁₂ + 12 O₂ → 9 CO₂ + 6 H₂O

The molar ratio of C₉H₁₂ to O₂ is 1:12. The moles of O₂ required to react with 0.67 moles of C₉H₁₂ are:

0.67 mol C₉H₁₂ × (12 mol O₂/1 mol C₉H₁₂) = 8.0 mol O₂

8.0 moles of O₂ are required to completely react with 0.67 moles of C₉H₁₂.
