Answer: The  volume is 57.52 mL if the temperature if raised to 343K.

Explanation:

Given: [tex]V_{1}[/tex] = 27 mL,       [tex]T_{1}[/tex] = 161 K

[tex]V_{2}[/tex] = ?,        [tex]T_{2}[/tex] = 343 K

According to Charles law, at constant pressure the volume of an ideal gas is directly proportional to temperature.

Formula used is as follows.

[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\\frac{27 mL}{161 K} = \frac{V_{2}}{343 K}\\V_{2} = 57.52 mL[/tex]

Thus, we can conclude that volume is 57.52 mL if the temperature if raised to 343K.

Answer:

B

Explanation:

Traits acquired during a lifetime are not passed on to offspring.

Answer: The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides

Explanation:

The moon's gravity affects the oceans nearest the moon because the moon's gravity pulls water into a tidal bulge is a true statement.

The tidal force is the result of the moon's gravitational pull.

The tidal force causes Earth—and its water—to bulge out on its closest and furthest sides from the moon. High tides cause these water bulges.

Thus, the statement is correct.

Answer:

You can make 149.1g of KCl

Explanation:

1 mole of potassium chloride, KCl, contains 1 mole of potassium, K. That means, with 2.000 moles of K we can make 2.000 moles of KCl. To solve this question we must convert these moles of KCl to mass in grams using its molar mass (Molar mass KCl = 74.5513g/mol):

Mass KCl:

2.000 moles KCl * (74.5513g / mol) =

Answer:

O Presence of nucleus in cells

Explanation:

Answer:

The compound with the correct formula is;

A. MNO₃

Explanation:

The number of oxidation states in the metal, M = One oxidation state

The formula of the compound formed by the metal, M = MHCO₃

We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1

Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;

The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.

Answer:

but you should

Explanation:

but you should

Answer:

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.

The correct equation for remaining radioactive nuclei is "Start Fraction 0.5 to the n power over A end Fraction"

Radioactive nuclei are unstable nuclei that decay by producing energetic particles like photons, electrons, neutrinos, protons, neutrons, or alpha particles (two protons and two neutrons bound together). Ionizing particles are a subset of these particles.

The number of radioactive nuclei will be remained after n life cycles:

A/A*= [tex](1/2)^{n}[/tex]

It can be written as, A=A*[tex](1/2)^{n}[/tex]

where, A is remaining material and A* is starting material.

Answer:

the mercury would be lowest at location 4.

Explanation: this is because pressure and altitudes have inverse relationship at the troposphere. higher altitude has lower pressure. also pressure at location 4 contribute to pressure at location 1. but pressure at location 1 do not contribute to pressure at location 4.

Answer:

10.1 M

Explanation:

Applying,

pH = -log(H⁺).................... Equation 1

But,

[H⁺][OH⁻] = 1×10⁻¹⁴................ Equation 2

Where [H⁺] = Hydrogen ion concentration, [OH⁻] = Hydroxyl ion concentration.

From the question,

Given: [OH⁻] = 1.25×10⁻⁴ M

Substitute into equation 2

[H⁺][1.25×10⁻⁴] = 1×10⁻¹⁴

[H⁺] = 1×10⁻¹⁴/1.25×10⁻⁴

[H⁺] = 0.8×10⁻¹⁰ M

[H⁺] = 8×10⁻¹¹ M

Also, Substitute the value of [H⁺] into equation 1

pH = -log[8×10⁻¹¹]

pH = 10.1 M

You can use a very simple formula for first order decay...

Fraction Remaining (FR) = 0.5n where n is the number of half lives that have elapsed.

In the current problem we want to find the FR, and we know n = 2 half lives elapsed (60 yr/30yr = 2)

FR = 0.52 = 0.25

Since we started with 5.0 g, and we have 0.25 (1/4) left, that would be 5.0 g x 0.25 = 1.25 g

Explanation:

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.
