Answer:
Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
Some extra info, but the main ones are there for you :)
Explanation:
Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
Esophagus. After you swallow, peristalsis pushes the food down your esophagus into your stomach.
Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.
Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.
Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.
Gallbladder. Your gallbladder stores bile between meals. When you eat, your gallbladder squeezes bile through the bile ducts into your small intestine.
Small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Large intestine. In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.

How many atoms in 13.88 mole of lead? (Round to 3 sig figs)
Answer:
8.36 x 10^24 atoms/molecules
Explanation:
Avagadro's Number: 6.02214076 × 10^23
Avagadro's Number shows the number of molecules in 1 mole of substance. In this case, if there is 13.88 moles of lead, we multiply 13.88 by Avagadro's number:
(6.02214076 × 10^23)(13.88) = 8.358536 x 10^24 = 8.36 x 10^24

pH 2.90 (the approximate pH of lemon juice
pH 3.86 (the approximate pH of sauerkraut)
pH 10.81 (the approximate pH of milk of magnesia)
pH 4.11 (the approximate pH of orange juice)
pH 11.61 (the approximate pH of household ammonia)
The pH of human blood ranges from 7.35 to 7.45 with it usually being around 7.40. If the blood pH gets below 7.35 a person goes into acidosis. If the pH gets above 7.45 a person goes into alkalosis. Both acidosis and alkalosis can be fatal. How much more acidic is a person’s blood if it has a pH of 7.3 compared to its preferred 7.4? How much more alkaline is a person’s blood if it has a pH of 7.6 rather than its preferred 7.4?
Answer:
Explanation:
pH = -log{H+]
{H+} = 10^(-pH)
pOH = 14 - pH
{OH-} = 10^(-pOH)
pH 2.90 (the approximate pH of lemon juice
{H+} = 10^(-2.9)
pOH = 14 - 2.9 = 11.1
{OH-} = 10^(-pOH) = 10^(-11.1)
pH 3.86 (the approximate pH of sauerkraut)
{H+} = 10^(-3.86)
pOH = 14 - 3.86 = 10.14
{OH-} = 10^(-pOH) = 10^(-10.14)
pH 10.81 (the approximate pH of milk of magnesia)
{H+} = 10^(-10.81)
pOH = 14 - 10.81 = 3.19
{OH-} = 10^(-pOH) = 10^(-3.19)
pH 4.11 (the approximate pH of orange juice)
{H+} = 10^(-4.11)
pOH = 14 - 4.11 = 9.89
{OH-} = 10^(-pOH) = 10^(-9.89)
pH 11.61 (the approximate pH of household ammonia)
{H+} = 10^(-11.61)
pOH = 14 - 11.61 = 2.39
{OH-} = 10^(-pOH) = 10^(-2.39)

The same amount of heat is added to a 10-g sample of each of the following metals. If each metal is initially at 20.0°C, which metal will reach the highest temperature? show your work
A. gold 0.129 J/(g °C)
B. beryllium 1.82 J/(g °C)
C. calcium 0.653 J/(g °C)
D. copper 0.385 J/(g °C)
Answer: A
Explanation:
A
Heat is the product of the mass, specific heat, and delta temperature. The gold metal will reach the highest temperature. Thus, option A is correct.
What is specific heat?Specific heat (c) is the heat required by a substance to get heated a unit mass by a unit of temperature. The specific heat is given as,
[tex]\rm c = \rm \dfrac{Q}{m \times \Delta T}[/tex]
Here, Q is the heat applied, m is the sample's mass and delta T is the change in the temperature.
The value of heat applied is the same for all the metals, so a change in temperature is calculated as,
[tex]\rm \Delta T = \rm \dfrac{Q}{c . m }[/tex]
From this, it can be said that the temperature is inversely related to the specific heat of the metal and hence the metal having the smallest c will have the highest change in the temperature.
Therefore, gold (c = 0.129 J/(g°C)) will reach the highest temperature.

Define ductility.
Ty!!
Explanation:
Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how ‘soft’ or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present. An increase in carbon, for example, will increase the strength but decrease the ductility.
Answer:
ductility of a metal able to be drawn out into a long thin wire.

According to his prelaboratory theoretical yield calculations, a student's experiment should have produced 1.44g of magnesium oxide. When he weighed his product only 1.23g of magnesium oxide was present. What is the student percent yield?
The percent yield of the product formed in the experiment is 85.41%.
What is percent yield?Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.
In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .
In the given example, actual yield=1.23 g and theoretical yield=1.44 g
Thus on substituting values in the given formula, 1.23/1.44×100=85.41 %.
Thus , the percent yield of sample is 85.41%.

In chemistry a coefficient denotes the number that is seen in front of the formula of a equation. The coefficient in the given equation 4CO₂ is 4.
What is a coefficient?A number which precedes the formulas of reactants and products in order to balance a chemical equation is defined as a coefficient. It represents the number of atoms or molecules of each elements which are present in the reaction.
A chemical equation should be balanced and it must obey the law of conservation of mass which states that the number of reactants and products on both sides of the equation should be equal.
The coefficients are the numbers which are required to balance a chemical equation and it may vary while balancing a equation. The coefficient is found to be 1 if no number is mentioned in front of the formula of the reactants and products.
In the given equation 4CO₂, 4 is the coefficient which shows that 4 'C' atoms and 8 'O' atoms are present in the compound CO₂.
Thus the coefficient in the compound 4CO₂ is 4.
